Flu (Influenza) Teen Version

What is influenza?

Influenza (flu) is a viral infection of the nose, throat, windpipe, and bronchi that occurs every winter. The main symptoms are a runny nose, sore throat, and nagging cough. Usually there's more muscle pain, headache, fever, and chills than colds usually cause.

What causes the flu?

Flu is caused by influenza viruses. Flu viruses change yearly, which is why people can get the flu every year. The virus is spread by sneezing, coughing, and hand contact. It spreads rapidly because the incubation period is only 24 to 36 hours and the virus is very contagious. Thus, the spread of flu is very difficult to prevent.

How can I take care of myself?

The treatment of influenza depends on your main symptoms and is no different from the treatment for other viral respiratory infections.

• Fever or aches: Take acetaminophen (Tylenol) every 6 hours or ibuprofen (Advil) every 8 hours for discomfort or fever over 102°F (39°C). Do not take aspirin because it may cause Reye's syndrome.
• Cough or hoarseness: Use cough drops.
• Sore throat: Suck on hard candy. Warm chicken broth may also help.
• Stuffy or blocked nose: Warm-water or saline nosedrops and nose blowing will open most blocked noses. You can buy saline spray without a prescription.

How long will the flu last?

The fever lasts 2 to 3 days, the runny or stuffy nose 1 to 2 weeks, and the cough 2 to 3 weeks.

How can I prevent influenza?

The influenza vaccine gives protection for 1 year. The vaccine is not generally recommended for healthy teens (unless an especially severe form of influenza comes along). Those with chronic diseases (for example, asthma) need to come in for yearly influenza boosters. Anyone who wants to reduce their chances of getting the flu can get the flu shot. Talk with your healthcare provider or parents if you think you should have flu shots.

When should I call my healthcare provider?

Call during office hours if:

• You develop any complications such as an earache, sinus pain or pressure, or a fever lasting over 3 days.
• You have other questions or concerns.
