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 thereâ€™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 8Â hours for discomfort or fever over 102Â°F (39Â°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 nose drops and nose blowing will open most blocked noses. You can buy saline spray without a prescription. Saline nose drops can also be made by adding 1/2 teaspoon of table salt to 1 cup (8 oz) of warm water.
- Fluids. Make sure you drink adequate fluids to prevent dehydration.
- Antiviral medicines: These medicines are recommended for teens with chronic disease who are at High Risk for complications, not for healthy teens. (CDC)
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?
All teens can benefit by getting the flu vaccine. Those with chronic diseases (for example, asthma) especially need to come in for yearly influenza boosters. Pregnant teens also are at high risk for complications from the flu and need to be protected by the vaccine. Anyone who wants to reduce their chances of getting the flu should get the flu shot. Talk with your healthcare provider or parents about 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.
