Jellyfish stings – Symptoms and causes


Jellyfish stings are relatively common problems for people swimming, wading or diving in seawaters. The long tentacles trailing from the jellyfish body can inject you with venom from thousands of microscopic barbed stingers.

Jellyfish stings vary greatly in severity. Most often they result in immediate pain and red, irritated marks on the skin. Some jellyfish stings may cause more whole-body (systemic) illness. And in rare cases jellyfish stings are life-threatening.

Most jellyfish stings get better with home treatment. Severe reactions require emergency medical care.

Common signs and symptoms of jellyfish stings include:

  • Burning, prickling, stinging pain
  • Red, brown or purplish tracks on the skin — a “print” of the tentacles’ contact with your skin
  • Itching
  • Swelling
  • Throbbing pain that radiates up a leg or an arm

Severe jellyfish stings can affect multiple body systems. These reactions may appear rapidly or several hours after the stings. Signs and symptoms of severe jellyfish stings include:

  • Stomach pain, nausea and vomiting
  • Headache
  • Muscle pain or spasms
  • Weakness, drowsiness, fainting and confusion
  • Difficulty breathing
  • Heart problems

The severity of your reaction depends on:

  • The type and size of the jellyfish
  • Your age, size and health, with severe reactions more likely in children and people in poor health
  • How long you were exposed to the stingers
  • How much of your skin is affected

When to see a doctor

Seek emergency treatment if you have severe symptoms.


Jellyfish tentacles contain microscopic barbed stingers. Each stinger has a tiny bulb that holds venom and a coiled, sharp-tipped tube. The jellyfish uses the venom to protect itself and kill prey.

When you brush against a tentacle, tiny triggers on its surface release the stingers. The tube penetrates the skin and releases venom. It affects the immediate area of contact and may enter the bloodstream.

Jellyfish that have washed up on a beach may still release venomous stingers if touched.

Types of jellyfish

While many types of jellyfish are relatively harmless to humans, some can cause severe pain and are more likely to cause a systemic reaction. These jellyfish cause more-serious problems in people:

  • Box jellyfish. Box jellyfish can cause intense pain. Life-threatening reactions — although rare — are more common with this type. The more dangerous species of box jellyfish are in the warm waters of the Pacific and Indian oceans.
  • Portuguese man-of-war. Also called bluebottle jellyfish, Portuguese man-of-war jellyfish live mostly in warmer seas. This type has a blue or purplish gas-filled bubble that keeps it afloat on the water and acts as a sail.
  • Sea nettle. Common in both warm and cool seawaters, sea nettles live along the northeast coast of the United States and are abundant in the Chesapeake Bay.
  • Lion’s mane jellyfish. These are the world’s largest jellyfish, with a body diameter of more than 3 feet (1 meter). They’re most common in cooler, northern regions of the Pacific and Atlantic oceans.

Risk factors

Conditions that increase your risk of getting stung by jellyfish include:

  • Swimming at times when jellyfish appear in large numbers (a jellyfish bloom)
  • Swimming or diving in jellyfish areas without protective clothing
  • Playing or sunbathing where jellyfish are washed up on the beach
  • Swimming in a place known to have many jellyfish


Possible complications of a jellyfish sting include:

  • Delayed hypersensitivity reaction, causing blisters, rash or other skin irritations one to two weeks after the sting
  • Irukandji syndrome, which causes chest and stomach pain, high blood pressure and heart problems


The following tips can help you avoid jellyfish stings:

  • Wear a protective suit. When swimming or diving in areas where jellyfish stings are possible, wear a wet suit or other protective clothing. Diving stores sell protective “skin suits” or “stinger suits” made of thin, high-tech fabric. Consider protective footwear as stings can also occur while wading in shallow water.
  • Get information about conditions. Talk to lifeguards, local residents or officials with a local health department before swimming or diving in coastal waters, especially in areas where jellyfish are common.
  • Avoid water during jellyfish season. Stay out of the water when jellyfish numbers are high.

Jellyfish Sting

Is this your child’s symptom?

  • Sting from a jellyfish
  • Jellyfish cause most of the stings that occur in sea water
  • The creature’s stinger injects venom into the human skin. This is what causes the sting.
  • The main symptoms are pain, burning and redness at the sting site. Red lines are common.
  • The Sea Nettle is a type of stinging jellyfish often found in Chesapeake Bay

Jellyfish Facts

  • They are umbrella shaped, clear sea creatures with long trailing tentacles. They move slowly through the water by pulsing the upper body. Also carried by ocean currents. Their tentacles can be 10 feet or longer.
  • Other Names. Jellies or sea jellies. Large groups of jellies are called a bloom. Blooms can close beaches.
  • Where They Live. Found in every ocean and coastline.
  • Numbers. Jellies have increased in numbers worldwide. Warmer ocean temps and pollution of ocean waters are factors. Fishing the ocean too much is also a cause. Tuna, shark and swordfish eat jellies.
  • Stings. Stings can occur while wading, swimming or diving in salt water. Honolulu gets over 1000 911 calls per month for stings.
  • Beached Jellies. Even beached or dying jellies can sting. So can pieces of tentacles floating in the water. They can release venom for up to 2 weeks.
  • Treatment. Vinegar is used to stop the venom in stingers. Caution: Do not use ammonia, urine, rubbing alcohol, fresh water or ice. They all can trigger the release of more venom. If you don’t have vinegar, move on to scraping off the stingers.
  • Prevention. Mainly do not go in the water where jellies are seen. Wearing a thin layer of clothing (such as pantyhose) also can protect you. Reason: The stingers are short and cannot puncture clothing. Special “stinger suits” can be bought in diving stores.

Cause of Sting Reactions

  • The long tentacles have thousands of stingers.
  • When a stinger is touched, it pierces the skin and injects venom.
  • The venom is what causes all the symptoms.

Types of Jellyfish Sting Reactions

  • Local Reactions are most common. Symptoms are raised, red lines that cross each other. The sting causes pain or burning at the site. Sometimes hives in the sting area occur. Blisters can occur in severe cases. Severe pain lasts 1-2 hours. Itch may last for a week. If the skin damage is severe, red or purple lines can last for weeks.
  • General Reactions can occur if there are many stings. More stings give a higher dose of venom. Large venom symptoms are vomiting, dizziness, weakness and headache.
  • Anaphylaxis (A severe allergic reaction). Life-threatening reactions are very rare with the stings. Most are caused by box jellyfish found in the South Pacific and Australia. The main symptoms are trouble breathing and swallowing, along with hives. It starts rapidly, most often within 20 minutes of the sting.

Care Advice for Jellyfish Sting

  1. What You Should Know About Jellyfish Stings:
    • Jellyfish cause most of the stings that occur in the ocean.
    • Most stings are harmless. The pain is like a bee sting.
    • Jellies have long tentacles with lots of tiny stingers.
    • Pieces of tentacles that wash up on the beach can still cause stings.
    • They produce lines of redness and burning pain.
    • Here is some care advice that should help.
  2. Step 1 – Sea Water Rinse to Remove Large Tentacles:
    • Rinse area with sea water. This will help remove any large tentacles stuck to the skin.
    • Do not rinse with fresh water (will trigger stingers).
    • Do not scrub or rub area (will trigger stingers).
    • Do this until you can get some vinegar.
  3. Step 2 – Vinegar Rinse to Stop the Stinging: (Exception: Chesapeake Bay jellyfish – see #6)
    • Rinse area with vinegar (5% acetic acid) for 15 minutes.
    • Reason: Stops the stingers from stinging if still attached to the skin.
    • Caution: Do not use with Chesapeake Bay jellyfish. (Reason: May trigger stingers. Instead, use a baking soda rinse with these stings).
    • Avoid rubbing alcohol for all stings. Reason: will trigger the stingers.
    • If you can’t get vinegar, move on to scraping off the stingers.
  4. Step 3 – Scrape the Area to Remove Small Stingers:
    • Scrape off any stingers you can see. Use the edge of a credit card or dinner knife.
    • Do not use your bare fingers. (Reason: you will get stings on your hands). Put on gloves if you have them.
    • Then, coat area with shaving cream or any mild cream. Scrape the area again.
    • If the stingers are stuck to body hair, shave with a razor.
  5. Step 4 – Repeat Vinegar Rinse: (Exception: Chesapeake Bay Jellyfish – go to #6)
    • Keep a cloth wet with vinegar on the area.
    • Do this for 15 more minutes.
  6. Chesapeake Bay Jellyfish (Sea Nettle) – Baking Soda Rinse To Stop The Stinging:
    • Rinse area with a mixture of sea water and baking soda for 15 minutes.
    • This stops the stingers from stinging if still attached to the skin.
    • Then, remove small stingers with scraping or shaving.
    • Caution: Do not use vinegar rinse.
  7. Pain Medicine:
    • To help with the pain, give an acetaminophen product (such as Tylenol).
    • Another choice is an ibuprofen product (such as Advil).
    • Use as needed.
  8. Cold Pack for Pain:
    • For pain and swelling, rub with an ice cube. You can also use a cold wet washcloth. Do this for 10 minutes as needed.
    • Caution: Don’t use until stingers are removed. (Reason: water or ice will trigger stingers).
  9. Steroid Cream for Itching:
    • For itching or swelling, put 1% hydrocortisone cream (such as Cortaid) on the sting.
    • No prescription is needed.
    • Use 3 times per day.
    • Keep the cream in the fridge. (Reason: it feels better if put on cold).

Jellyfish Stings: Symptoms, Causes, Treatments


What are jellyfish stings?

Jellyfish are sea creatures that live in all of the world’s oceans. They have soft, bell-shaped bodies with lengthy tentacles.

Many jellyfish have stinging cells called nematocysts in their tentacles. These cells contain a poisonous substance (venom) that helps jellyfish protect themselves. The venom also helps them capture food by stinging it.

Some of the jellyfish whose stings can be serious include box jellyfish, lion’s mane, Portuguese man-of-war, and sea nettle.

Symptoms and Causes

What causes jellyfish stings?

People may come into contact with the nematocysts of a jellyfish when they are swimming in the ocean or walking on the beach. This contact can cause the venom from the nematocysts to be injected into the body. More than 150 million jellyfish stings happen in the world each year.

Depending on the type of jellyfish and how much of the skin touches the venom, the sting can cause pain or other serious health problems. Some jellyfish stings can be life-threatening. It is important to get medical help if you have severe symptoms after a jellyfish sting.

What are the symptoms of jellyfish stings?

The symptoms of jellyfish stings depend on the type of jellyfish you made contact with. Mild jellyfish stings usually cause minor pain, itching, and, in some cases, a rash.

More serious jellyfish stings can cause greater harm. You should get medical help if you have more severe symptoms, including:

  • Difficulty breathing
  • Chest pain
  • Muscle cramps
  • Skin blistering
  • Numbness or tingling
  • Nausea or vomiting
  • Difficulty swallowing
  • Worsening redness, rash or pain if a sting gets infected

Management and Treatment

How are jellyfish stings treated?

Most people do not need to see a doctor for a jellyfish sting. Symptoms of a jellyfish sting usually go away after a few hours. Sometimes, a rash remains from a few days to two weeks.

You can treat mild jellyfish stings with the following steps:

  1. If you are stung at the beach or in the ocean, pour sea water onto the part of your body that was stung. Do not use fresh water.
  2. Use tweezers to remove any tentacles you see in your skin.
  3. Next, apply vinegar or rubbing alcohol to the affected area to stop the burning feeling and the release of the toxin.
  4. After you have poured vinegar on the site, apply shaving cream or a mixture of baking soda and sea water. When this is dry, scrape the mixture off with a credit card.
  5. To help reduce the pain, apply calamine lotion or hydrocortisone cream. You can also use an ice pack or hot water to help with the pain and swelling.

Your doctor may treat more serious jellyfish stings with medications to relieve pain, neutralize the venom’s effects (antivenin) and reduce the itching and rash (antihistamine).


How can jellyfish stings be prevented?

People can be stung by a jellyfish any time they are in or near the ocean. To reduce your risk of being stung:

  • Ask lifeguards or park rangers if any jellyfish are present around your beach. (Some beaches post a warning flag when jellyfish are reported.)
  • If you surf or dive in the ocean, wear a protective body suit.
  • Never touch a jellyfish that has washed up on shore. Dead jellyfish still have venom in their tentacles that can sting on contact.

First Aid Treatment for Jellyfish Stings

Call 911 if:

  • The person displays signs of a severe allergic reaction.
  • The sting is from a box jellyfish.
  • The sting covers more than half an arm or leg.

For more information about severe allergic reaction, see Anaphylaxis.



1. Get Out of the Water

2. Stop the Stinging

  • Rinse the area with vinegar for at least 30 seconds.
  • Remove tentacles with a pair of tweezers.
  • After you remove the tentacles, soak the affected area in hot water (104-113 F or 40-45 C) for at least 20 minutes. If you don’t have a thermometer, make sure the water is hot but not scalding. A hot shower is OK if that’s easier than soaking. Stay in the water for 20 to 45 minutes.
  • These treatments are based on research done in the Indo-Pacific areas and may not work for all stings.

3. Treat Discomfort

4. Follow Up

For less severe stings:

  • Use ice packs or over-the-counter pain relievers or antihistamines for welts.
  • Clean open sores three times a day and apply antibiotic ointment. Bandage if needed.

For a severe reaction:

  • You may be in the hospital for several days.
  • You need antivenin (also called antivenom) for Australian box jellyfish stings. Get to an ER and get the antivenin as quickly as you can.

How to Treat a Sting on or Near Your Eyes

It’s OK to wash your eyes with seawater. But get to the ER as soon as you can. They’ll flush your eyes with saline and give you pain medications. The ER doctor will probably send you to an ophthalmologist, a doctor who specializes in eye care.

Do Home Remedies Work?

Not really. Most are unproven. You may hear about these, but don’t try them:

  • Baking soda
  • Meat tenderizer
  • Pressure bandage
  • Urine
  • Alcohol
  • Scraping out stingers
  • Rinse with fresh water
  • Rub with a towel

Symptoms, What to Do & What to Avoid


Jellyfish use their stings to subdue their prey. Their tentacles are armed with thousands of nematocysts that can pierce the skin and inject venom. Depending on the species and the venom dose, a sting can cause reactions ranging from mild to life-threatening.


Jellyfish stings are common with an estimated 150 million incidences per year. Most are mild and readily treatable at home.

The symptoms of a mild jellyfish sting may include:

  • A stinging, prickling, or burning pain
  • Red or purplish “track marks” along the route of contact with the tentacle
  • Local itching and swelling
  • Throbbing pain radiating up an arm or leg
  • Rash (occasionally)


There is a lot still unknown about the causes of a severe reaction to jellyfish stings, in part because there are over 2,000 species of jellyfish around the world.

While most jellyfish stings are relatively mild, some can be severe and even life-threatening. This risk varies not only by the jellyfish species and venom dose but also by the individual’s response to the venom.

In some cases, the symptoms may be caused by the venom itself (typically a neurotoxic reaction affecting the heart and respiration). In others, a sting may provoke a severe reaction known as anaphylaxis in which the immune system over-reacts to the venom. Both may be involved and are often difficult to tell apart.

In most cases, a severe reaction will occur immediately or soon after the sting. However, if anaphylaxis is involved, reactions have been known to be delayed for days and even weeks.

Symptoms of a severe jellyfish sting include:

  • Numbness or tingling
  • Shortness of breath
  • Wheezing
  • Chest pain
  • Muscle cramps
  • Hives
  • Blistering skin
  • Nausea or vomiting
  • Difficulty swallowing
  • Rapid heartbeat
  • Heart palpations
  • Dizziness or fainting

Symptoms like these require immediate medical care. Call 911 or have someone rush you to the nearest emergency department.

If left untreated, anaphylaxis can lead to shock, coma, heart or respiratory failure, or death.

Images of Jellyfish Stings, First Aid


Jellyfish are aquatic invertebrates that can sting people who come into direct contact with them. The stingers, which are typically located on the ends of the jellyfish tentacles, contain poisons that are often toxic to humans.

Although most jellyfish are not especially dangerous to people, some are extremely toxic.

Portuguese man-of-war is not actually a jellyfish but rather a colony of small, predatory animals (hydrozoan). However, due to their similarity with jellyfish, this information applies to Portuguese man-of-war stings as well.

First Aid Guide
The rescuer should take care to avoid injury by wearing gloves and protective clothing or any readily available barrier.

  1. Remove the affected individual from the water.
  2. Wipe stingers or tentacles off with a towel.
  3. Wash the affected area with salt water.

Some self-care measures will help some jellyfish stings but will cause an adverse reaction in other types. For that reason, the following should be avoided without advice from a medial professional.

  • DO NOT wash or soak the affected area with fresh water if the injury occurred in salt water.
  • DO NOT apply vinegar, urine, alcohol, or meat tenderizer/water solution to the affected area.
  • DO NOT rub the affected area.
  • DO NOT raise the affected area above the level of the heart.
  • DO NOT give the person medication.

Who’s at risk?

Stings from jellyfish most often occur in salt water, while swimming or wading, when a person accidentally comes into contact with the jellyfish. Stings from some jellyfish may also occur if a person comes into contact with jellyfish that have washed onto the beach or detached tentacles in the water. Certain jellyfish tentacles that have become detached are still capable of causing stings for 2 weeks or more. Jellyfish stings sometimes occur in fresh water as well.

Signs and Symptoms

A jellyfish itself consists of a bell shape with suspended tentacles. They open and close their bell-like body to drift and slowly swim in the water.

The sting of a jellyfish may appear swollen, red, and bleeding. The affected area may burn and feel painful.

Additionally, the person who has been stung by a jellyfish may experience the following:

  • Nausea or vomiting
  • Paralysis
  • Sweating
  • Weakness
  • Difficulty breathing
  • Cramps
  • Diarrhea
  • Pain in unaffected areas, such as the groin or armpit

When to Seek Medical Care

Seek medical care if the person is having difficulty breathing, is bleeding profusely, or other body-wide (generalized) symptoms are occurring, such as the following:

  • Nausea or vomiting
  • Paralysis
  • Sweating
  • Weakness
  • Cramps
  • Diarrhea
  • There is pain in an area not directly affected by the jellyfish sting, such as the groin or armpit

Treatments Your Physician May Prescribe

In the case of some jellyfish stings, such as a sting from the box jellyfish of Australia, an antivenin may be necessary to treat the symptoms of anaphylactic shock.

The treatment may vary depending on the type of jellyfish sting. General treatment measures for most jellyfish stings are as follows:

  1. Immerse the sting area in hot water until pain is relieved.
  2. Remove tentacles (if still present) with forceps.
  3. Remove stingers (nematocysts) with shaving cream and a razor.
  4. Administer pain reliever and treat itching.

Are you treating jellyfish stings with the right liquid? – Find a DO

An estimated 150 million people are stung by jellyfish globally each year. In most cases, the sting is painful, but not life-threatening and easily treatable.

For a rare few, a sting can lead to vomiting, trouble walking, nausea, headaches, and seizures. The most dangerous sting—from the box jellyfish found in Australia and the South Pacific—can cause anaphylaxis, a severe allergic reaction that can lead to death. Symptoms include trouble breathing and swallowing, along with hives.

How to know if you’ve been stung by a jellyfish

A jellyfish sting will lead to painful, irritated marks on the skin. These red, brown or purplish tracks are the imprint of where tentacles made contact with skin. Hives or blisters may occur in the sting area.

Victims of a jellyfish sting commonly describe burning, prickling or stinging sensations.

“For the vast majority of cases, the pain begins within minutes, peaks approximately five minutes after the sting and lessens in a few hours,” says Robert Greer V, DO, a third-generation osteopathic physician with a family practice in West Palm Beach, Florida. “While the pain will vary greatly in severity, it generally won’t last longer than 24 hours.”

Itching can linger for a week and marks on the skin may last for weeks.

What is the best treatment?

Advice varies slightly by region, but physicians broadly agree upon the following three treatment steps.

First, remove any tentacles or stingers that remain on the skin with a pair of tweezers or gloved hands. Do not touch the stingers with bare hands.  In a pinch, a credit card or other utensil can be used, but be careful not to spread the venom onto untouched skin.

The second step is to rinse the area with a topical treatment like Sting No More or vinegar, commonly available at lifeguard stations. Finally, apply a heat pack or immerse the affected area in hot water for 20-40 minutes.

The use of a mild hydrocortisone cream or an oral antihistamine may help relieve itching and swelling.

Seek medical attention for worsening symptoms or if you experience swelling or a throbbing pain that radiates up a leg or an arm. Stings to the eyes or mouth should be treated by a physician.

What not to do

While it may be tempting to immediately rinse the affected water, do not pour cold drinking water on the sting because it can release more venom and increase your pain. In the absence of vinegar or sting spray, wash with saltwater.

Urinating on the sting will not help.

“Pure fiction,” says Dr. Greer. “We don’t know how the pee myth evolved but it’s not a good practice.”

Do not use bare hands to wipe the area because the venom may still be active.

How to prevent jellyfish stings

Talk to lifeguards, local residents or officials with a local health department before swimming or diving in coastal waters, especially in areas where jellyfish are common. Stay out of the water when jellyfish numbers are known to be high.

When swimming in areas where jellyfish are present, wear a wet suit or other protective clothing. Diving stores sell protective “stinger suits” made of thin, high-tech fabric. Protective footwear is encouraged in shallow water.

Why do jellyfish sting people?

Because jellyfish are slow, weak animals, they use their tentacles to sting and immobilize their prey by discharging a tiny, harpoon-like structure that carries venom. Jellyfish do not seek humans so stings usually result from accidental contact, notes Dr. Greer.

Tentacles that have detached from the jellyfish can continue to sting. Avoid touching jellyfish at all times, even if they have washed up on the beach.

90,000 first aid and burn treatment

Going to the sea, especially to foreign countries, remember that you can return home not only with happy memories. Sea waters have their own inhabitants, communication with which can lead to unpleasant consequences. A jellyfish sting is one of the most common results of such contact. In such a situation, it is better to have at least minimal information and know what to do if a jellyfish stung.

How does a jellyfish bite

At first glance, jellyfish are harmless creatures that can be admired at the depths of the sea or near the coast.But, not everything is as rosy as it seems at first glance. Of course, there are individuals that are harmless to humans, but there are also those that can thoroughly ruin the rest on the Cote d’Azur. From a jellyfish bite, the consequences are very serious.

Poisonous specimens are mainly found abroad. Relatively harmless Aurelia, Kornerota and Mnemiopsis live in the Black Sea waters. However, they can also cause discomfort.

Jellyfish sting with the nematocysts available to them – stinging cells that all coelenterates are endowed with.Thus, they defend themselves from enemies and get their own food. The stings contain toxic substances that cause a lot of painful sensations and other unpleasant manifestations.

A jellyfish bite occurs with the nematocysts they have.

Stinging cells end in sensitive hairs, contact with which provokes the ejection of a long sharp thread that penetrates the human skin. Upon penetration into the body, the tip of the thread breaks off, and the poison contained in it gradually penetrates into the epidermal layers. Usually, toxins cause nerve symptoms. More serious consequences depend on the type of jellyfish.

Symptoms and manifestations after a jellyfish bite

The peculiarities of burns of some types of jellyfish include slowly developing symptoms. The first signs may appear an hour after the bite. It is then that the maximum concentration of poison in the blood occurs, and until that time the person does not even suspect about the danger. In order not to waste time and immediately take action, you need to know what a jellyfish bite looks like.

The external signs of a burn are the same for all types of coelenterates, but they appear with different intensity. This is redness in the affected area, skin redness, the formation of small red rashes or blisters, which can then fill with fluid and form bruises. If you are stung by a weakly poisonous jellyfish, then such manifestations will be less sensitive. A person feels itching and severe burning, acute pain up to and including loss of consciousness upon contact with ocean inhabitants. The toxins of the most dangerous species of jellyfish can leave numerous scars, ulcers and abscesses on the affected areas.Penetrating into the skin, the poison will gradually cause a general allergic reaction from other vital systems:

  • nausea, dizziness and vomiting;
  • 90,021 muscle spasms and cramps;

    90,021 pelvic and abdominal pain;

  • paralysis of the diaphragm;
  • arrhythmia and increased blood pressure;
  • 90,021 interruptions in breathing;

    90,021 diarrhea;

  • sweating and general malaise.

Nausea, dizziness and vomiting are the main symptoms of a jellyfish bite

In severe cases, anaphylactic shock, coma and even death can develop.If the painful sensations persist, and the unpleasant symptoms intensify, an urgent need to consult a doctor. This condition is especially dangerous for children and the elderly.

First aid, what to do after a jellyfish bite

Most jellyfish stings cause nothing more than discomfort and do not require medical attention. But if you observe in yourself or another victim the manifestation of a strong allergic reaction, the rash has spread over a large area of ​​the body, or the bite was made by a particularly poisonous individual, then the minutes of delay may end badly.It is important to know what a jellyfish burn looks like in order to immediately begin therapeutic measures. First aid for a jellyfish sting is as follows:

  • Carefully and slowly you need to get out of the water. Panic and sudden movements will accelerate the absorption of toxic substances into the blood;
  • Remove the remnants of the tentacles from the skin. The stinging cells remaining in the body can introduce an additional portion of toxic substances into you and aggravate the situation.

Carefully lift the tentacles and remove them from the surface of the body;
  • the place of the jellyfish burn should be washed well with salted sea water or prepared saline solution. Shaving foam will also work. Such methods stop the spread of poison.

What is strictly forbidden to do after a bite

Lack of awareness leads to wrong actions on the part of the victim and subsequent complications. It is strictly forbidden to rub the affected areas, even if they are very itchy.Such actions will lead to a rush of blood and activation of stinging cells. The poison in them will begin to be released faster and penetrate the skin.

Never use fresh water to rinse burns. This is due to the fact that stinging cells under the influence of water, the salinity of which is lower than the salinity of seawater, begin to disintegrate very quickly and release toxins abundantly. You can use fresh water if all remnants of the tentacles are removed from the skin.

No matter how urinotherapy is promoted for a jellyfish bite, it is not advisable to do so. You do not know the percentage of salinity of urine, and if it is not sufficient, you can aggravate the situation. Also, urine may contain microorganisms that, if they enter an open wound, can cause infection.

Treatment of the bite with iodine or brilliant green will increase irritation and inflammation, spreading them to healthy areas of the skin. Do not try to drown the unpleasant manifestations with alcohol. This will provoke the spread of the poison inside.

Don’t get too close to the jellyfish. The tentacles of some species can be very long and too thin to be seen in muddy waters. In such situations, there is an increased risk of being stung.

Do not swim in storms or large waves. Scraps of tentacles that have retained their poisonousness may lie in wait for you already near the coast.

Stay alert when sailing in warm sea or ocean. The transparent body of the jellyfish can visually dissolve in water and contact with it will be inevitable.When going to the beach, make sure that there you can be provided with timely assistance or take with you a minimum set of pharmacy supplies.

Jellyfish Sting | First Aid Courses

Most jellyfish hide in their seductive jelly-like body stinging cells – nematocytes, which produce the poison that jellyfish need to protect themselves from enemies and kill their prey. When the jellyfish touches, they act like a harpoon: they shoot, are fixed on the skin and inject nerve poison into the victim’s body through the thinnest channel.

  • How not to spoil the rest in Primorye

    Summer is the time of vacations and long-awaited relaxation on the beach or on a hike. However, residents of Primorye and guests of the Primorsky Territory should not forget about the dangers of summer holidays, such as heat and sunstrokes, snake and jellyfish bites. Primorskaya Gazeta reports on how to behave when faced with the dangers of the summer period and how to provide first aid to the victim.

    By the way

    A jellyfish lying on the shore can keep poison in its tentacles for three days.Therefore, parents need to be careful when children walk along the shore and try to take a jellyfish lying on the shore

    Jellyfish on the beach
    The “bite” of a jellyfish is not dangerous for humans. It feels like a nettle burn, this is an unpleasant moment, but there were no deaths in Primorye. Jellyfish usually appear off the coast when the weather is hot for a long time, so vacationers should beware of swimming places where there is a lot of algae, jellyfish can be there.

    Assistance Instruction:
    • It is necessary to leave the sea on land;
    • Wash the place with fresh water;
    • Do not touch, do not rub the bite site;
    • Drink more fluids to detoxify the body;
    • Do not drink alcohol or wipe the bite site with it;
    • You can remove the remnants of the tentacles of the jellyfish with a blunt knife blade, but without touching the very site of the bite, so that the poison does not spill back into the skin.

    – To avoid complications after a bite, you can drink an allergy medicine like Suprastin. In case of deterioration of the condition, the appearance of a headache, nausea or vomiting, as well as if the bite site turns red, swollen and a small rash appears, you need to call an ambulance. For some people, the condition after a jellyfish bite may look like a cold: joint aches, sore throat, dry cough, ”said Lyudmila Savelyeva, head of the health monitoring and information-analytical work of the Regional Center for Medical Prevention.

    Alcohol should not be consumed with bites because its narcotic effect dulls the feeling of pain, but when alcohol leaves the body, the pain intensifies.

    Snake bit
    Active rest in hiking mode helps not only to see the beauty of the region, but also prepares surprises, for example, a meeting with a snake. When meeting with these cold-blooded people, you need to freeze and try to leave slowly, without making any sudden movements.

    – You can find out that a person was bitten by a snake by looking at the wound, there will be two punctures.With a snake bite, everything is individual. There may be various allergic reactions, asthma attacks. The condition can worsen up to the point of loss of consciousness, so you need to call an ambulance and do nothing yourself, ” said Lyudmila Savelyeva.

    By the way

    Most often, according to expert snake-catcher Viktor Litvintsev, in Primorye, city residents are disturbed by the patterned and Amur snakes. Both reptiles are not poisonous, but catching them on your own is dangerous to the life and health of citizens.
    – The patterned snake itself is not aggressive, but it is better not to catch it without gloves, – specified the snake catcher. – The Amur snake also loves to bite. Moreover, if the hand is pulled back sharply, the snake’s teeth will probably remain in the hand. They are very easily pulled out of her mouth. If this happens, you can gently remove them from the skin with tweezers and disinfect the wound with alcohol, iodine, or calendula tincture.

    In total, 10 species of snakes are found in Primorye, Viktor Litvintsev specified. A third of these snakes are venomous. For example, the Sakhalin viper.The reptile lives mainly in the north of the region in Pozharsky, Terneisky and Krasnoarmeysky districts.

    Assistance Instruction:
    • Put an antiseptic cool bandage on the bite site;
    • In no case do not suck, do not squeeze anything out of the bite site and do not wrap tightly;
    • Drink more fluids to detoxify the body;
    • Call an ambulance.

    All bites of jellyfish, snakes, mosquitoes, horseflies, wasps and other insects should be well blotted with soda solution or vinegar solution.The irritation can be relieved by a compress or lotion. You will have to make it at home and take it with you.

    Heat and sunstroke occur quite often in summer, and it is not so easy to distinguish them from each other due to similar symptoms. Anyone can overheat in the sun, while not only high temperature and humidity, but also too dense, poorly breathable clothing, physical overstrain, alcohol consumption, overeating will help to get hit.The first signs of heatstroke are headache, weakness, dizziness, pain in the legs, dry mouth appears, intense thirst and the face turns purple. The signs of sunstroke are identical, the only difference is that heatstroke can be obtained due to overheating of the body during a long stay outside in hot weather, and sunstroke is the direct effect of direct sunlight on the brain.

    Assistance Instruction:
    • Move the victim to a shade, cool place;
    • Put a damp cloth on your head and apply cold compresses;
    • Constantly moisturize the skin;
    • Drink more fluids to detoxify the body;
    • If the person gets worse, put him on his side and call an ambulance.

    • Gently pluck out the visible tentacles with fine tweezers

    However, residents of Vladivostok should be careful, because in the water you can accidentally stumble upon a jellyfish and get an unpleasant burn. RIA VladNews has compiled a list of useful tips on how to recognize a jellyfish bite and provide first aid.

    First aid for jellyfish stings:

    • First you need to get out of the water. Fear, prolonged exposure to water and physical activity only increase the spread of poison throughout the body;

    • Remove the remnants of the jellyfish from the affected skin area.As you know, the tentacles of jellyfish contain poisonous stinging cells. If the tentacles are not removed in time, even more poison can enter the body. Never touch the tentacles with your bare hands!

    • Stop the spread of the poison. Apply something cold to the bite and then treat with salt water or hydrogen peroxide;

    • It is necessary to take one of the listed drugs – “Diazolin”, “Claritin”, “Loratadin”, “Suprastin” – to relieve swelling and eliminate an allergic reaction;

    • Remove toxins from the body. To do this, soak a cloth in a soda solution, apple cider vinegar or ammonia and apply it to the affected area of ​​the skin.

    Drinking plenty of water, sweet tea or compote also contributes to the early elimination of poison from the body.

    What is forbidden to do with jellyfish bites:

    • Rub the affected skin area and touch it with unprotected hands. This can lead to an increase in the spread of toxic substances.

    • Flush burns with fresh water.Fresh water increases pain by destroying cells.

    • Look out for warning signs on the beach

    • Do not try to catch a passing jellyfish

    • Also, do not touch jellyfish that were washed ashore

    • Do not enter the sea after a storm

    Residents of Vladivostok should be extremely careful when swimming in the seas, because in the water you can stumble upon the most dangerous jellyfish of the Primorsky Territory.

    The cross jellyfish lives in the thickets of the sea grass zostera or, in other words, the scum. This jellyfish is very easy to recognize – inside its transparent body, a cruciform pattern is visible, formed by painted internal organs. 60 thin tentacles with stinging cells are located along the edges of the umbrella. Contact with these tentacles causes painful burns, and a repeated bite can become very serious for a person and lead to death.

    Rescuers reminded Primorye residents of what a cross looks like: it is a small jellyfish with a tall transparent yellowish-greenish dome with a diameter of 2.5 centimeters, 60 thin tentacles and a transparent body. The jellyfish swims close to the shore during the hottest months of summer and can hit a person while in the water.
