Influenza (flu)

respiratory system, including the nose, throat, and lungs. It is caused by the influenza virus, which spreads easily from person to person through respiratory droplets when an infected person coughs, sneezes, or talks. The flu virus can also survive on surfaces for several hours, making it possible to contract the virus by touching a contaminated object and then touching the nose, mouth, or eyes.

The flu typically begins with symptoms such as fever, chills, cough, sore throat, runny or stuffy nose, body aches, and fatigue. In some cases, people may also experience diarrhea and vomiting, although these symptoms are more common in children than in adults. The severity of symptoms can vary widely, ranging from mild to severe, and can lead to complications such as pneumonia, bronchitis, sinus infections, and ear infections, particularly in young children, elderly adults, and people with weakened immune systems.

The flu can be prevented by getting an annual flu vaccine, which is recommended for everyone over the age of 6 months, especially those at high risk of complications. The flu vaccine contains killed or weakened strains of the flu virus, which stimulate the immune system to produce antibodies that can recognize and fight the virus if exposed to it. Other preventive measures include washing hands frequently, covering coughs and sneezes, avoiding close contact with sick people, and staying home when sick.

Treatment for the flu typically involves supportive care, such as rest, hydration, and over-the-counter pain relievers to reduce fever and alleviate symptoms. Antiviral medications, such as oseltamivir (Tamiflu), can also be prescribed by a doctor to shorten the duration of symptoms and reduce the risk of complications, but are most effective when taken within the first 48 hours of symptom onset.

Disease Causes

Influenza (flu)

Influenza viruses travel through the air in droplets when someone with the infection coughs, sneezes or talks. You can inhale the droplets directly, or you can pick up the germs from an object — such as a telephone or computer keyboard — and then transfer them to your eyes, nose or mouth.

People with the virus are likely contagious from about a day before symptoms appear until about five days after they start. Children and people with weakened immune systems may be contagious for a slightly longer time.

Influenza viruses are constantly changing, with new strains appearing regularly. If you've had influenza in the past, your body has already made antibodies to fight that specific strain of the virus. If future influenza viruses are similar to those you've encountered before, either by having the disease or by getting vaccinated, those antibodies may prevent infection or lessen its severity. But antibody levels may decline over time.

Also, antibodies against influenza viruses you've encountered in the past may not protect you from new influenza strains that can be very different viruses from what you had before.

Disease Prevents

Influenza (flu)

The Centers for Disease Control and Prevention (CDC) recommends annual flu vaccination for everyone age 6 months or older. The flu vaccine can reduce your risk of the flu and its severity and lower the risk of having serious illness from the flu and needing to stay in the hospital.

Flu vaccination is especially important this season because the flu and coronavirus disease 2019 (COVID-19) cause similar symptoms. Flu vaccination could reduce symptoms that might be confused with those caused by COVID-19. Preventing the flu and reducing the severity of flu illness and hospitalizations could also lessen the number of people needing to stay in the hospital.

It may be possible to get a COVID-19 vaccine at the same time as your flu vaccine.

This year's seasonal flu vaccine provides protection from the four influenza viruses that are expected to be the most common during the year's flu season. This year, the vaccine will be available as an injection and as a nasal spray.

The nasal spray isn't recommended for some groups, such as:

Children under 2
Adults 50 and older
Pregnant women
Children between 2 and 17 years old who are taking aspirin or a salicylate-containing medication
People with weakened immune systems
Kids 2 to 4 years old who have had asthma or wheezing in the past 12 months

If you have an egg allergy, you can still get a flu vaccine.

Disease Treatments

Influenza (flu)

Usually, you'll need nothing more than rest and plenty of fluids to treat the flu. But if you have a severe infection or are at higher risk of complications, your doctor may prescribe an antiviral drug to treat the flu. These drugs can include oseltamivir (Tamiflu), zanamivir (Relenza), peramivir (Rapivab) or baloxavir (Xofluza). These drugs may shorten your illness by a day or so and help prevent serious complications.

Oseltamivir is an oral medication. Zanamivir is inhaled through a device similar to an asthma inhaler and shouldn't be used by anyone with certain chronic respiratory problems, such as asthma and lung disease.

Antiviral medication side effects may include nausea and vomiting. These side effects may be lessened if the drug is taken with food.

Most circulating strains of influenza have become resistant to amantadine and rimantadine (Flumadine), which are older antiviral drugs that are no longer recommended.
