How to Know if You Have the Flu

Influenza, commonly called the flu, is a contagious viral infection.

A respiratory illness, mild to moderate cases of the flu can cause symptoms like runny nose, sore throat, body aches, headaches and fatigue. Some people with the flu may also experience a fever, feverish chills, vomiting or diarrhea, but not everyone has these symptoms.

If left untreated, the flu can lead to further health concerns, like sinus infections and pneumonia, according to the CDC. Some of these complications, such as pneumonia, myocarditis (inflammation of the heart) and encephalitis (inflammation of the brain) can lead to severe complications or, in rare cases, death.

Pregnant people, children younger than five, adults over 65 and those with pre-existing chronic conditions like diabetes or heart disease are most at-risk for more severe flu symptoms and complications.

Telling the Difference Between the Flu, a Cold and COVID-19

While the flu is serious, it can occasionally be difficult to diagnose because symptoms are so similar to other illnesses, such as the common cold and COVID-19.

While only a medical professional like your general practitioner can make a true diagnosis, people with the flu are more likely to experience symptoms such as fever, aches and chills than people with a cold. Sneezing and a runny nose are more common with the cold.

Telling the difference between COVID-19 and the flu can be trickier. In the case of COVID-19, symptoms tend to be more severe and last longer, and it’s known to spread more easily than the flu. The only way to tell which you have for sure, however, is to test for both.

How Long Does the Flu Last?

Flu symptoms usually appear two to three days after contact with the virus, according to the University of Pennsylvania Health System, but you may start to feel sick anywhere from one to seven days after contracting it. After four to seven days, most symptoms should diminish, though fatigue and a persistent cough can last longer.

However, according to Gregory Buller, M.D., the Chairman of Medicine and Associate Chief Medical Officer at Bridgeport Hospital in Connecticut, these numbers are highly subjective and the flu can actually last longer. “Generally, symptoms last five to seven days, though those with weakened immune systems and infants may be symptomatic longer. Those with immune system problems and infants may be contagious for a longer period too,” he explains.

Those who have already gotten their flu shot may experience less severe symptoms which often go away earlier than the four-to-seven-day mark.

The flu doesn’t usually last as long as a cold (which the CDC states can last anywhere from seven to 10 days).

How Long is the Flu Contagious?

While not as contagious as COVID-19, the flu can spread rather quickly. Someone with the flu can pass the virus on to another person before any sign or symptoms, and five to seven days after symptoms develop. Usually, the flu is most contagious within the first three to four days after symptoms start.

Even if someone feels like they’ve recovered from the flu, it’s important to remember that they can still infect others within that five-to-seven-day window.

While the exact timeframe that one is contagious may be hard to pin down, a good way to know when it’s safer to be around people again is a lack of fever for 24 hours “without the need to use a fever-reducing medicine, such as Tylenol,” explains Michael Jhung, M. D., the associate director of epidemiologic science (ADES) in the CDC’s Influenza Division “Until then, you should stay home from work, school, travel, shopping, social events and public gatherings,” he continues.

This is especially important if you work in a school, medical facility or a setting where high-risk groups, such as those with chronic illnesses, the elderly and children younger than five, frequent, stresses Dr. Jhung. Stay away from family, coworkers and friends who are at high risk until you are completely sure your symptoms have gone away.

Treating the Flu

While most people will recover from the flu on their own, anyone who is over the age of 65, has a weakened immune system or chronic disease, lives in a nursing facility or is pregnant should see a doctor after they first notice flu-like symptoms, advises Dr. Buller. Additionally, severe cases of the flu—such as those that occur in individuals already in a hospital—may need to be treated with antiviral medication.

If you find yourself sick with the flu and don’t have any preexisting conditions that may put you at risk for complications, stay at home and rest as much as possible. Over-the-counter pain medications can help reduce fever and other symptoms. Staying warm and drinking enough fluids can also help.

If you find that your symptoms are not getting better or seem to be getting worse, the CDC recommends watching out for the following warning signs that the flu might be taking a turn for the worse:

  • Persistent chest pain or difficulty breathing
  • Seizures
  • A lack of urination
  • Severe weakness, muscle pain or unsteadiness
  • A worsening of medical conditions from a chronic illness
  • Symptoms that get better but then return

Warning signs differ for children and it’s always best to discuss personalized warning signs with your doctor since the CDC’s list is not exhaustive.

How to Protect Yourself Against the Flu

The best way to protect yourself from the flu and complications from it is to get your annual flu shot. Approximately two weeks after getting your flu shot, your body is better suited to avoid the strain of the virus most prevalent in a given year. Not only are you less likely to contract the flu after getting the shot, but symptoms should be less severe and disappear quicker if you have your shot.

Despite its effectiveness, the flu shot is not recommended for infants under six months and anyone with an allergy to gelatin, antibiotics or other flu shot ingredients. If you have an egg allergy or have had Guillain-Barré Syndrome, a condition where a person’s own immune system attacks their nerves, consult your doctor before getting the shot.

Along with getting a flu shot, you can lower your chances of contracting the flu by practicing healthy habits. “In addition to flu vaccination, take everyday preventive actions that are recommended to reduce the spread of flu like avoiding close contact with people who are sick, limiting contact with others if you’re sick, covering coughs and sneezes and washing hands often with soap and water,” states Dr. Jhung.

The CDC also recommends refraining from touching your face when in public, disinfecting surfaces and staying hydrated. Eating well and getting enough sleep can also boost your immune system against the flu.

While the flu is a serious illness, there are many ways to protect yourself against it, from getting your flu shot to naturally boosting your immune system. If you do get the flu, there’s a good chance you’ll be able to recover at home and be back to business as usual within a week.

How Long Does the Flu Last? Stages & Symptoms

Key takeaways

  • The flu is a respiratory virus affecting the throat, nose, and sometimes the lungs.

  • It typically takes about two weeks to recover from the flu.

     

  • You are contagious two days before symptoms appear and up to seven days after they appear.

     

When symptoms like a sore throat and stuffy nose set in, you often wonder two things: What is this, and how long will it last? You could be dealing with allergies, a cold, or the flu, and each has a different timeline. How long the flu lasts depends on your general health but in general usually lasts about one to two weeks.

In this article, we break down the lifecycle of the flu, including how long you may experience symptoms, when you are contagious, and how long you should avoid interacting with others. We also advise when you should consider seeing a doctor.

How Long the Flu Lasts

The influenza virus causes the flu, a contagious respiratory sickness that affects the throat, nose, and sometimes the lungs. For healthy individuals, the flu is typically a fairly short-term illness, lasting no longer than a week or two. Luckily, you won’t feel miserable the entire time. Below is a timeline of a bout of the flu.

Incubation period

The time from when you’re exposed to a virus until symptoms first begin is called the incubation period. For the flu, this takes one to four days, with an average of two days. This means you may be contagious a day or two before symptoms start and can unknowingly spread the virus during that time.

Symptoms appear

Symptoms like cough, sore throat, fever, and runny nose generally show up one to four days after being exposed to the influenza virus. Not everyone has the same symptoms, and certain symptoms, like vomiting and diarrhea, are more common in children or with certain strains of the flu. If your symptoms are severe or you are immunocompromised, consider seeking medical care at this time. 

Symptoms peak

Flu symptoms generally peak two to four days after they begin, then begin to gradually improve on their own. You are also most contagious three to four days after symptoms start. Symptoms may include:

  • Fever or chills
  • Cough
  • Sore throat
  • Runny or stuffy nose
  • Body aches
  • Headaches
  • Fatigue

Symptoms taper off

For otherwise healthy individuals, flu symptoms typically begin tapering off five days after they start. However, coughing and a general “sick” feeling may last for more than two weeks, especially for the elderly and those with chronic lung disease. 

Recovery

With rest, over-the-counter (OTC) medications, and plenty of fluids, you’ll be on the road to recovery in no time. However, even as you begin to feel better, it’s important to stay away from others for a little while to ensure you don’t spread the flu. You are contagious from 5-7 days after symptoms emerge, so it’s best to stay home for a week after you first begin feeling sick. If fever is one of your symptoms, stay home for at least 24 hours after your fever is gone.  

How Long Are You Contagious?

The flu virus is thought to spread by tiny droplets released into the air when sick people cough, sneeze, or talk. These droplets land on surfaces others may touch or go directly into the other person’s eyes, nose, or mouth causing them to get sick. 

If you have the flu, you were contagious even before you had symptoms. Before people start feeling symptoms, they are contagious for one or two days. Once symptoms start, you are contagious for the first five to seven days after getting sick. People with weakened immune symptoms or children, may be contagious for even longer. 

How to Treat the Flu

Prompt treatment with antiviral drugs, within two days of getting symptoms, may lessen symptoms and shorten the duration of your sickness by one or two days. They may also prevent severe complications like pneumonia. Not everyone needs antiviral drugs but those with compromised immune systems or the elderly may benefit.  

If you have the flu, be sure to stay home and distance yourself from others. If you do need to go out for any reason, wear a mask, cover your coughs and sneezes with a tissue, and wash your hands frequently. Allow yourself plenty of time to rest and be sure to keep yourself hydrated.

When to See a Doctor

With proper self-care, the flu typically goes away on its own, especially if you are otherwise healthy.

However, certain high-risk people should seek medical care when they come down with the flu to help watch for and prevent any serious complications such as pneumonia.

This includes: 

  • Adults 65 and older
  • Anyone with chronic illnesses (especially those that affect the lungs or immune system)
  • Pregnant people
  • Very young children with severe symptoms

Antiviral medications can help make flu symptoms go away about one day faster.

However, these need to be started within 72 hours of symptoms appearing, they can have bothersome side effects, and they do not prevent serious complications like hospitalization, pneumonia, or death.

Your healthcare provider can help you determine if these medications are right for you.

Frequently Asked Questions

What is the fastest way to recover from the flu?

The best thing you can do to recover from the flu as fast as possible is to stay hydrated, rest, and isolate. There is no cure for the flu, antibiotics are ineffective against it, and antiviral medications like oseltamivir (Tamiflu) only make symptoms go away about one day more quickly and can have side effects. Over-the-counter medications may provide some relief from symptoms, but they do not make the flu go away any faster.

How long does immunity to the flu last after getting sick?

Because there are so many different strains, it’s hard to say how long immunity to the flu lasts after getting sick. On the other hand, if you get the flu shot, you’re protected against multiple variations of the virus for about six months.

How long should you stay at home with the flu?

Because the flu easily spreads from person to person, it’s important to stay home when you may be contagious. Generally, this is from a day before and up to seven days after symptoms start. So stay home for a week after you first feel sick to help keep others safe.

How long the flu is contagious and the first signs of the disease

According to the World Health Organization, about 1 billion people in the world become infected with the flu every year. The peak of activity of this severe viral infection occurs in autumn and winter. Due to the possible severe course of the disease, influenza is especially distinguished from other acute respiratory viral infections.

Influenza symptoms

The severity of the symptoms and how long the flu lasts depends on the person’s health and age. The disease is more difficult for children, pregnant women, the elderly, people with weakened immune systems and chronic diseases.

The main difference between influenza is an acute onset: the temperature rises sharply (up to 38-39.5 degrees), but on the first day there are no catarrhal phenomena. There are signs of infectious intoxication:

On the second or third day, cough, chest pain, runny nose may appear. In the absence of complications, the fever lasts 2-4 days, and the person recovers in 7-10 days.

How long flu is contagious

The virus spreads rapidly through the air. The incubation period is several days, during which a person already becomes contagious – before the first signs appear, and then another 5 days (for adults) or up to 7 days (for young children).

Prevention of influenza

Doctors recommend the following measures to prevent influenza infection:

  • strengthening immunity

  • regular and thorough hand hygiene

  • 900 02 ventilation of premises

  • vaccination – according to indications

For reinforcement The body’s defenses are important to a healthy lifestyle with a sufficient level of physical activity and a balanced diet, as well as taking vitamins.

Vitamins for the prevention of influenza

First of all, you need to pay attention to the 3 main trace elements with immunostimulating properties: vitamin C, vitamin D and Omega-3.

Vitamin C is a water-soluble micronutrient that our body cannot synthesize on its own, so it must be obtained from food. Participates in many important processes and performs the following actions:

  • increases the activity of natural killer cells – a special type of lymphocytes that are responsible for human innate immunity

  • strengthens cell membranes and prevents the penetration of viruses

  • neutralizes free radicals that can damage cells and cause the development of various diseases, as well as premature aging

  • reduces the duration of viral infections

Vitamin D is produced in the skin under the influence of ultraviolet light. Due to insufficient sun exposure, many people are deficient in this vitamin, so doctors recommend taking it extra. The main task of vitamin D is to promote the absorption of calcium and phosphorus, but its benefits in other areas have also been proven:

  • strengthening immunity, reducing the risk of developing infectious diseases0004

  • Improvement of physical endurance

  • Maintaining health of the cardiovascular system

omega-3 polyunsaturated fatty acids are indispensable and should be present in the human diet. They are contained in cell membranes, regulate metabolism, and also:

  • activate the immune system

  • provide an antioxidant effect

  • help maintain tone, energy and good mood

The incidence of acute respiratory viral infections and influenza in Russia continues to grow, and, according to Rospotrebnadzor, the majority of patients suffer from influenza – it was detected in 70% of patients with symptoms of an acute respiratory viral infection. Of course, few people take the flu as seriously as covid, and this is understandable – the majority endure the disease without complications. However, for those who are at risk – the elderly, young children, patients with chronic diseases, it can be deadly. That is why the patient should, if possible, isolate himself from them while he is contagious.

— In complicated cases of SARS, that is, a viral infection and influenza, well, about seven days from the onset of the disease, that is, from the onset of symptoms, says Dr. Andrey Pozdnyakov. – As a rule, further the body completely eliminates the virus from itself and the person is no longer contagious. Therefore, about a week, sometimes less, especially if a person has met this virus before.

Andrey Pozdnyakov — infectious disease specialist, candidate of medical sciences, chief physician of the clinical diagnostic laboratory of OOO INVITRO-Siberia.

At the same time, a person will no longer be contagious in a week, even if the symptoms and complications of the disease persist. Even if a secondary bacterial infection joins, there is no contagiousness at this point, as with covid.

– In order for a person to be contagious, it is necessary that a sufficient amount of viral particles be released from the upper respiratory tract per unit time, – explains immunologist Nikolai Kryuchkov. When the symptoms go away, the person is no longer contagious. But if you need to determine exactly, then you need to look at PCR by this moment. If the PCR is negative, then the person is not contagious.

Nikolai Kryuchkov — Immunologist, General Director of LLC Clinical Excellence Group, Associate Professor of the I. M. Sechenov Medical University.

The most insidious in terms of contagiousness is the extremely mild course of the flu. A person may feel only mild manifestations of symptoms, but not pay attention to them, because they do not interfere in any way.

– At the same time, it can be contagious – however, the contagious period will be shorter. That is, this is not an incubation period, but, as it were, an infection, but very weakly manifested, – says Nikolai Kryuchkov.

The incubation period for influenza is less than a week, and during the incubation period, a person does not spread the virus, contagiousness occurs just before the onset of symptoms. For covid, for example, this is about a day before the onset of symptoms, and for the flu even later – a few hours.

Influenza, like other acute respiratory viral infections, usually begins with weakness, fever, general malaise. The head of Rospotrebnadzor, Anna Popova, noted earlier that the so-called swine flu, which is circulating this year, does not have any specific symptoms. However, it has its own characteristics – it causes an active epidemic process in high seasons, that is, when there are more cases than usual – these occur about once every five years.

Because more people get sick, there are more deaths during swine flu years. Statistics on the number of cases and deaths from influenza in recent months has not yet been published, but individual reports of deaths come from different regions. Recently, we talked about the sudden deaths of children diagnosed with SARS – in early December, several such cases became known at once.

  • Doctors say that ARVI and flu spread during the cold season, but it can be said that it has just begun. Understanding how long the flu outbreak will last;
  • Along with the increase in the incidence of influenza, the daily increase in covid patients is also growing. Read what happens if you get infected with two viruses at once;
  • nevertheless, no anti-epidemic measures were introduced at the federal level.
