Influenza (flu) – Better Health Channel

What is influenza (flu)?

Influenza (flu) is a highly contagious viral infection of the respiratory tract that can cause severe illness and life-threatening complications (including pneumonia). It affects people of all ages. The flu is usually spread by breathing in droplets from coughs and sneezes that contain the virus.

The flu is a seasonal infection that usually occurs from April to September. Flu seasons vary in severity and duration from year to year. In a year of high influenza activity, it is estimated that the flu can contribute to more than 3,300 deaths in Australia.

Even healthy people can sometimes die from the flu. Some Victorians are at increased risk of serious disease and complications of flu, like young children, the elderly, pregnant women, Aboriginal and Torres Strait Islander people and people with a weakened immune system or a chronic medical condition.

During 2023, amidst the fourth year of the COVID-19 pandemic in Australia, continued seasonal flu activity is anticipated as borders remain open and interstate and international travel increases.

Vaccination is key to protecting yourself and those around you from the flu.

Symptoms of the flu

The most common symptoms of the flu are:

• sudden appearance of a high fever (38°C or more)
• a dry cough
• body aches (especially in the head, lower back and legs)
• feeling extremely weak and tired (and not wanting to get out of bed).

Other symptoms can be:

• chills
• aching behind the eyes
• loss of appetite
• sore throat
• runny or stuffy nose.

Having the flu is even more likely if you have been in contact with someone who already has it.

Diagnosing the flu

Flu and other kinds of viruses can only be confirmed by a doctor after a nose or throat swab has returned positive results.

Difference between the flu and COVID-19

The symptoms of COVID-19External Link and the flu can be similar.

If you are unwell with flu-like symptoms, contact the COVID-19External Link hotline on 1800 675 398 (24 hours, 7 days a week) or your GP to check if you require COVID-19 testing.

The symptoms of COVID-19 to watch out for are:

• loss or change in sense of smell or taste
• fever
• chills or sweats
• cough
• sore throat
• shortness of breath
• runny nose.

Some people may also experience headache, muscle soreness, stuffy nose, nausea, vomiting and diarrhoea.

What to expect with the flu

Symptoms of the flu can hit very quickly and may last several weeks. A bout of the flu typically follows this pattern:

• Days 1–3: Sudden appearance of fever, headache, muscle pain and weakness, dry cough, sore throat and sometimes a stuffy nose.
• Day 4: Fever and muscle aches decrease. Hoarse, dry or sore throat, cough and possible mild chest discomfort become more noticeable. You may feel tired or flat.
• Day 8: Symptoms decrease. Cough and tiredness may last one to two weeks or more.

What about flu complications?

In some cases of the flu, severe illness and complications (such as pneumonia and bronchitis) can develop. This can result in hospitalisation and even death.

The flu can also make some existing medical conditions worse.

In Victoria, flu vaccination is free for people with a higher risk of severe complications associated with the flu:

• all children aged 6 months to less than 5 years
• Aboriginal and Torres Strait Islander people from 6 months and over
• pregnant women – at any stage of pregnancy
• people 65 years and over
• people aged 6 months and older with medical conditions putting them at higher risk of severe flu and its complications:
  • cardiac disease
  • chronic respiratory conditions
  • chronic neurological conditions
  • immunocompromising conditions
  • diabetes and other metabolic disorders
  • renal disease
  • haematological disorders
  • children aged 6 months to 10 years on long term aspirin therapy.

Speak to your immunisation provider to see if you meet the eligibility for free flu vaccine.

How can I avoid getting the flu?

Getting a flu vaccine every year is recommended for everyone aged 6 months or older. People in the above groups are eligible for free flu vaccination each year under the National Immunisation ProgramExternal Link.

While not 100% effective, the flu vaccine provides a high level of protection and can reduce symptoms in those still getting sick.

COVID-19 vaccinesExternal Link can be co-administered (that is, given on the same day, one after the other) with a flu vaccineExternal Link. Speak to your immunisation provider for advice about COVID-19 and flu vaccines for children aged 6 months to less than 5 years.

Wearing a face mask and practicing good hand hygiene can help to reduce your chances of catching the flu or passing it on to others.

I think I have the flu – should I see a doctor?

Anyone at a higher risk of serious illness with flu-like symptoms should see their doctor as soon as possible.

Most people who are generally healthy won’t need to see their doctor for the flu. As symptoms of the flu are similar to COVID-19, talk to your doctor about testing for COVID-19 infection.

If you have the flu, try to rest, maintain a good fluid intake, and manage your symptoms. This will help you recover and prevent dehydration. Your immune system will fight the infection and symptoms will usually clear up on their own.

If you do need to see a GP for your symptoms, make sure you call ahead first so they can make sure there’s no one in an at-risk group around when you have your appointment.

When to seek medical attention

See your doctor if you have any concerns or are in a high-risk group for severe infection. Seek immediate medical attention if you experience any of the following symptoms:

• difficulty breathing
• chest pain
• sudden dizziness
• confusion
• severe vomiting
• fever with a rash.

How can I avoid giving the flu to other people?

It is important we all play our part in helping fight the flu and to protect our health system.

Aside from getting your flu shot, follow these 3 simple steps to stop the spread of the flu:

Step 1 – Cough or sneeze into your elbow

If you feel a cough or sneeze is coming on, make sure to cough or sneeze into your elbow. It’s a part of your body less likely to touch other surfaces and will help stop the spread of nasty germs.

Step 2 – Wash your hands thoroughly and regularly

• Our hands are one of the top spreaders of viruses. The flu virus is carried in almost invisible droplets from saliva, sneezes, coughs, and runny noses.
• Flu viruses can live on surfaces such as lift buttons or handrails for up to 48 hours and are spread when people touch an infected surface.
• Wash your hands thoroughly and often with soap and water for at least 20 seconds – especially if you have been in a public place, or after blowing your nose, coughing, sneezing or using the toilet. If soap and water are not readily available, use a hand sanitiser containing at least 60% alcohol.

Step 3 – Rest and recover at home

• If you are sick, rest at home and drink plenty of fluids. Avoid going out, even to the supermarket, where you risk spreading the virus to others. Wear a mask if you need to go out.
• If you start to experience more serious symptoms, seek medical attention.

Looking after yourself when you have the flu

The best things you can do to look after yourself when you have the flu are:

• Rest – you will probably feel very weak and tired until your temperature returns to normal (about 3 days). Rest provides comfort and allows your body to use its energy to fight the infection.
• Stay at home – stay away from work, school and any places where you may have contact with others, especially while you are contagious. The period during which adults are contagious is usually around 3–5 days from when the first symptoms appear, and up to 7 days in younger children.
• Drink plenty of fluids – extra fluids are needed to replace those lost because of the fever (through sweating). If your urine is dark, you need to drink more. Try to drink a glass of fluids, such as water, every hour while you are awake.

What medications should I take for the flu?

The flu is a viral infection so antibiotics won’t help and should not be taken.

Antiviral medications, if started in the first 2 days after symptoms start, can shorten the length of your illness. These need to be prescribed by your doctor.

Decongestants and simple pain relievers can help you feel better while your body’s immune system fights off the infection.

Tips for buying over-the-counter medications

Follow these tips for buying over-the-counter medication for the flu:

• Buy a remedy that treats only one symptom – this way you are not taking any substances you do not need, or that may trigger an adverse reaction.
• Read the medication label and check:
  • whether the active ingredient treats your symptoms
  • possible side effects
  • possible interactions with any medications, (including prescription and over-the-counter, medicines (such as vitamins and mineral supplements and herbal medicines)
  • whether the medication is safe for you to take if you have any health conditions
• If you are unsure if a medication is suitable for you to take, or if you have any other questions, talk to your doctor or pharmacist. They can suggest a medication that is appropriate and safe for you to take.

Useful tips to aid recovery from the flu

Other useful flu recovery tips include:

• Take simple pain-relieving medication (such as paracetamol or ibuprofen), as directed on the packet, to ease muscle pain and bring down your fever (unless your doctor says otherwise).
• Never give any medications that contain aspirin to children (under 12 years) unless advised by a doctor. The combination of the flu and aspirin in this age group has been known to cause Reye’s syndromeExternal Link – a very serious condition affecting the nervous system and liver.
• Antibiotics are not effective against the flu because influenza is a virus, and antibiotics fight bacteria. However, your doctor may prescribe them if you develop a bacterial infection on top of the flu.
• Gargle with a glass of warm water to ease a sore throat. Sucking on sugar-free lollies or lozenges also helps.
• A hot water bottle or heating pad may help relieve muscle pain. A warm bath may also be soothing.
• Use saline nose drops or spray to help soothe or clear a stuffy nose. These decongestants help shrink swollen blood vessels in the nose. Talk to your doctor or pharmacist about which medication will be the best for you.
• Do not smoke – this will irritate your damaged airways.
• Try warm, moist air inhalation. Boil a kettle, wait a minute for the water to slightly cool, and carefully empty the hot water into a bowl. Place the bowl on a steady surface, such as a table. Put a towel over your head and inhale the warm air in the bowl for up to 20 minutes. There is no need to add anything to the water. Be careful not to touch the water and keep it out of reach of children.
• Ask for help if you live alone or care for others. You may need support until you feel better.
• Remember, if you buy medicine at the pharmacy to treat your symptoms (over-the-counter medications), check with the pharmacist to see which one is right for you. Let them know if you have a chronic illness or are taking any other medication.

signs, symptoms, treatment and prevention

Influenza is a severe viral infection that affects men, women and children of all ages and nationalities. Influenza epidemics happen every year, usually during the cold season. In terms of the number of cases in the world, influenza and SARS rank first, the share in the structure of infectious diseases reaches 95%.

Influenza and SARS, gradually undermining health, reduce the average life expectancy of a person by several years. In severe cases of influenza, irreversible damage to the cardiovascular system, respiratory organs, and central nervous system often occurs, provoking heart and vascular diseases, pneumonia, tracheobronchitis, and meningoencephalitis.

Influenza collects the greatest victims among the elderly population groups suffering from chronic diseases.

The influenza virus is very easily transmitted:

• The most common route of transmission is airborne.
• It is also possible and household transmission, for example, through household items.

When coughing, sneezing, talking, particles of saliva, mucus, sputum with pathogenic microflora, including influenza viruses, are ejected from the nasopharynx of a patient or a virus carrier. An infected zone is formed around the patient with a maximum concentration of aerosol particles. The range of their scattering usually does not exceed 2 – 3 m.

What is SARS? How is it different from the flu?

The term “acute respiratory disease” (ARI) or “acute respiratory viral infection” (ARVI) covers a large number of diseases that are largely similar to each other. Their main similarity lies in the way of transmission (they enter the body along with inhaled air through the mouth and nasopharynx) and in a set of symptoms:

• The patient has a fever, sore throat, cough, chills, muscle pain and headache for several days.
• The most common symptom of respiratory illness is a runny nose; it is caused by a number of related viruses known as rhinoviruses.

With recovery, all these symptoms disappear and do not leave behind any traces.

In general, the causative agents of acute respiratory infections are transmitted from person to person through coughing or sneezing of the patient. Any person in close (approximately 1 meter) contact with another person with symptoms of SARS is at risk of exposure to potentially infectious inhaled droplets. Viruses can enter the body (in the eyes, nose or mouth) through the hands when in contact with an infected surface.

Personal hygiene can help prevent the spread of pathogens that cause respiratory infections.

Differences between COVID-19, colds and flu

As you know, the new coronavirus infection COVID-19 is transmitted mainly by airborne droplets. She is characterized by the presence of clinical symptoms of SARS (you can find a detailed educational program from Sevdzdrav at the link – https://sevdz.ru/mednavigator/profilaktika/koronavirus/).

Important! COVID-19 is sometimes asymptomatic, but this does not make the carrier of the virus any less contagious. Especially in such cases, people with chronic diseases suffer.

Basic recommendations for the prevention of influenza and SARS for the population

It is especially important to observe preventive measures now – during the pandemic of a new coronavirus infection.

The self-isolation regime has been canceled, but the pandemic has not disappeared anywhere! We all need to think about our health and the health of those around us.

• Avoid close contact with people who appear unwell, show fever (temperature) and cough.
• Avoid crowded places or reduce time spent in crowded places.
• Avoid touching your mouth and nose.
• Observe hand hygiene – wash hands frequently with soap and water or use an alcohol-based hand sanitizer, especially when touching the mouth, nose.
• Increase the flow of fresh air into living quarters, open windows as often as possible.
• Use a mask when in contact with a sick person.
• Maintain a healthy lifestyle, including adequate sleep, eating “healthy” foods, and being physically active.

Preventive immunization of the population (vaccination) is the best prevention of influenza. In turn, the main danger of refusing to vaccinate is the possibility of getting the flu when in contact with a sick person. In addition, a person who has not been vaccinated is potentially dangerous to others, as he is a likely carrier of an infectious disease.

In detail: why vaccination is needed and where to get a flu shot in Sevastopol.

Recommendations for people with symptoms of SARS

• If you feel unwell, stay at home and follow the recommendations of the doctor, if possible, keep a distance (1 meter) from healthy people.
• Rest and drink plenty of fluids.
• Cover your mouth and nose when coughing or sneezing with a handkerchief or other suitable material. Dispose of this material immediately after use or wash it. Wash your hands immediately after contact with secretions from the respiratory tract!
• Wear a mask if you are in the common area of ​​the house near other people.
• Tell your family and friends about the illness.

Important! Medical masks

Recommendations for the use of protective medical masks:

• The wearing of medical masks is mandatory for persons who have close contact with a sick patient.
• Carefully put on the mask so that it covers the mouth and nose, and tie it tightly so that there are as few gaps between the face and the mask as possible.
• Avoid touching the mask when using it.
• After touching a used mask, for example when removing it, wash your hands with soap and water or an alcohol-based hand sanitizer.
• Replace the used mask with a new, clean, dry mask as soon as the used mask becomes damp (wet).
• Masks intended for single use should not be reused.
• Throw away disposable masks after each use and dispose of them immediately after removal.

Home Care Guidelines

• Isolate the patient from others by at least 1 meter from others.
• Cover your mouth and nose when caring for the sick using masks.
• Wash hands thoroughly with soap and water after each contact with a sick person. Allocate separate towels for each family member.
• Other than the caregivers, the sick person should not be visited by other visitors.
• If possible, have only one adult in the home care for the sick.
• Avoid being cared for by a pregnant woman.
• Constantly ventilate the room in which the patient is located.
• Keep the room clean with detergents.

Advice for Parents of Sick Children

• Seek medical attention if your child is sick.
• Leave a sick child at home unless he needs medical attention.
• Give your child plenty of fluids (juice, water).
• Create a comfortable environment for your child, peace is extremely important.
• If your child has a fever, sore throat and body aches, you can give him antipyretics prescribed by the doctor according to the patient’s age.
• Keep tissues and tissue basket within reach of the patient.
• Teach the children to wash their hands frequently with soap and water for 20 seconds. Parents should also follow this procedure, which will serve as a good example for children.
• Teach children to cough and sneeze into a tissue or hand. Parents should also follow this procedure, which will serve as a good example for children.
• Teach the children not to come closer than one and a half to two meters from the sick.
• Sick children should stay at home (not attend preschools and schools) and keep their distance from other people until their condition improves.
• Refrain from frequent visits to crowded places.
• If your child has been in contact with someone who has the flu, ask your doctor if you need to take antiviral medicines to prevent the flu.

Acute respiratory viral infections and influenza – GBUZ “DLRC Krasnodar” MH KK

Acute respiratory viral infections and influenza

Acute respiratory (respiratory) viral infections (ARVI) – a group of diseases caused by viruses with similar transmission routes (mainly airborne, that is, through the air with particles of saliva) and clinical manifestations (cough, fever, sore throat, etc. .).

Influenza belongs to the ARBI group, but it is especially distinguished due to the pronounced tendency of this infection to spread with the development of epidemics. In addition, influenza is accompanied by more pronounced clinical
manifestations and with it a higher risk of complications. There is a subspecies of the H5N1 influenza virus that is transmitted from sick birds (ducks, chickens) to humans.

This type of flu is called “avian flu”.

SARS are the most common diseases, they account for 90% of all infections. In Russia, from 27 to 40 million people fall ill with ARVI every year.

ARVI viruses are excreted from the patient’s body with drops of saliva and sputum when breathing, talking, crying, coughing, sneezing. Viruses enter the body of a healthy person by inhaling infected particles or by sharing household items (dishes, towels). The highest probability of infection is in close contact and high crowding: in transport, in barracks, hospitals, educational institutions, nursing homes, etc. Susceptibility to respiratory infections is very high, but can be reduced with preventive measures (see below).

SARS are dangerous with complications, which, however, do not occur often. A typical complication of any SARS is pneumonia. Influenza, in addition, can be complicated by inflammation of the paranasal sinuses, middle ear (especially in children), respiratory distress syndrome (pulmonary edema), meningitis. Influenza is most dangerous for young children, the elderly, as well as for patients with HIV infection, diabetes mellitus and people with weakened immunity due to radiation or chemotherapy.

The disease begins with an increase in body temperature up to 38-40 ° C, which persists for 2-7 days. It should be remembered that a repeated increase in body temperature (that is, after its initial decrease) is not typical for 0PBI and may indicate either the development of complications or the presence of another disease. Another common symptom is a cough, usually dry. It is important to remember that a dry cough can persist after SARS for 1-2 weeks, which should not cause concern, provided that all other symptoms have disappeared and the patient’s health has returned to normal. Dry cough is gradually replaced by a cough with sputum. If the sputum becomes green, this does not necessarily indicate the development of complications: this color of sputum can be given by an admixture of discharge from the mucous membranes of the oral cavity, nose or bronchi. Among other symptoms of acute respiratory viral infections and flu, the most common are headache, muscle pain, sore throat, weakness, and poor appetite. A runny nose for influenza is not typical, but it is possible with other SARS.

Particular attention should be paid to symptoms that may indicate either the development of complications, or the presence of not SARS, but another disease that manifests similar symptoms.

Preservation of elevated body temperature (more than 37.5 ° C) for more than 7 days, as well as its repeated increase.

• Increased headache.

• Vomiting.

• Drowsiness or confusion.

• Stiff neck (inability to bend the head so that the chin touches the chest).

• Shortness of breath (difficulty breathing).

• Chest pain.

• Bloody sputum.

• Any rash.

• Intolerance to bright light.

If you experience any of these symptoms, contact your
doctor immediately!

Most often, the diagnosis is based on the identification of the symptoms discussed above. To identify complications of acute respiratory viral infections, a general blood and urine test, an x-ray of the chest or paranasal sinuses, and sometimes a bacteriological analysis of sputum may be required.

It is necessary to observe the home regimen (should not go to work, this is fraught with complications). Drinking should be plentiful to prevent dehydration in conditions of high body temperature.

Antipyretic drugs should be taken if the body temperature is above 38.5 °C, or if it is not well tolerated. In other cases, there is no need for them, since a moderately elevated body temperature contributes to the formation of a good immune response. Of the antipyretic drugs, paracetamol or acetylsalicylic acid is most justified (the latter – only if the patient is over 16 years old, in no case should it be prescribed for young children with influenza!).

To relieve the symptoms of SARS, there are many medicines containing several components. As a rule, these are combinations of antipyretics, relieving nasal congestion, antitussives, antiallergics, and vitamins. Always read the instructions carefully: the composition of the drug may contain a component that is either intolerable to you or already taken in a sufficient dose (for example, paracetamol).

Many patients take all sorts of herbal infusions or other herbal remedies to relieve coughs. These agents may contribute to subjective improvement, but they do not reduce the duration of the disease. Let’s take multivitamins, but the consumption of ascorbic acid should not be excessive (no more than 50-100 mg 2-3 times a day for children and 50-100 mg 3-5 times a day for adults).

The following medicines are used to influence ARVI pathogens:

– Antiviral drugs that stop viruses from multiplying, such as rimantadine (it is only effective for influenza).

– Interferons (the main factor of antiviral protection in the body) and stimulants for the formation of interferons.

– Anti-influenza immunoglobulin (the drug is obtained from the blood of healthy people who have had the flu; thus, it contains ready-made antibodies). Immunoglobulin is administered to weakened people, as well as to patients with severe forms of influenza.

– Antibiotics are not used for the treatment of uncomplicated forms of SARS and influenza, since they do not affect viruses. The most important influenza prevention measure is vaccination, which is carried out much earlier than the expected epidemic, usually in October-November. The duration of the protective effect of the vaccine is one year, so it must be repeated annually. Vaccination is most indicated for the following population groups (however, in any case, you should consult with your doctor before conducting it).

– Elderly people (over 65).

– Patients with chronic bronchopulmonary diseases (especially with chronic obstructive pulmonary disease).

– Children of preschool and school age.

– Immunocompromised patients (with diabetes mellitus, HIV infection, spleen removed or receiving glucocorticoids and cytostatics).

– Patients with chronic heart failure, chronic kidney disease.

– Patients with frequent acute respiratory viral infections.

– Persons with a high probability of infection (military contingents, medical personnel, workers in the field of consumer services, transport, educational institutions).

There are practically no contraindications to modern generation vaccines obtained by genetic engineering.

During an influenza epidemic, it is too late to administer the vaccine. In this case, it is possible to use rimantadine, as well as oxolinic ointment in the nose. It is important to frequently ventilate the room where the patient is located, if possible, isolate him from other family members, and provide him with separate dishes.
