INFLUENZA (FLU) FACT SHEET (return
to fact sheets)
Influenza,
commonly known as “the flu” is an acute respiratory
illness caused by the influenza virus. It is spread through the
air when an infected person coughs or sneezes and is very contagious.
Flu symptoms can last a week or more and interfere significantly
with school and work. Most people recover completely but, unlike
the common cold, influenza may cause severe illness with complications,
such as pneumonia. In an average year, 114,000 people are hospitalized
with the flu and 20,000 die of complications.
Who is at risk?
- Anyone can get the flu
- People who live in crowded conditions, such
as dormitories, have a higher risk of exposure to all respiratory
illnesses including the flu
- The elderly and people with weakened immune
systems are at the highest risk of complications
- People with diabetes, chronic heart disease
and respiratory disease, such as asthma, are also at greater
risk of complications
What are the symptoms?
- Sudden onset of fever
- Headache and body aches
- Dry cough, sore throat, runny nose
- Eye irritation and pain with eye movement
- Excess tiredness and weakness
If you are not sure if you have the flu or some
other viral or respiratory infection, please make an appointment
to be evaluated by a provider.
What can I do to prevent the flu?
There is a safe and effective vaccine for flu. The
vaccine is made from killed flu virus and cannot give you the
flu. Because the virus changes each year, the make up of each
year’s flu vaccine changes too, necessitating annual flu
shots for protection. Because flu “season” usually
peaks each year between December and March, we usually recommend
getting the flu shot in the fall. As with any other vaccine, flu
vaccine may not protect 100% of those exposed to the virus. People
who should especially consider getting the flu vaccine include:
- People with chronic medical conditions such as
diabetes, heart disease, asthma or other chronic respiratory
conditions
- People with weakened immune systems due to medical
conditions or certain medications
- People living in crowded conditions (such as
dorms or apartments) who are at higher risk of exposure to the
virus
- People (like some college students) whose lifestyles
include high levels of stress, inadequate nutrition and inadequate
sleep
What should I do if I think I have the flu?
- Drink plenty of fluids (non caffeinated, non
alcoholic) to prevent dehydration
- Rest to promote healing
- Gargle with salt water (1/2 tsp. per 8 oz. warm
water) to soothe sore throat
- Take over the counter (OTC) acetaminophen or
ibuprofen as directed for fever and aches
- Take OTC decongestants as directed for runny
nose
- Do not take aspirin when you have the flu due
to the risk of developing Reye’s Syndrome (a syndrome
that can cause serious brain and liver damage)
What about medicines to treat the flu virus?
There is no cure for the flu. Antibiotics are of
no use because they do not work on viral illnesses. There are
antiviral drugs that have been approved for treating the flu.
They reduce the duration of symptoms by about 1 day if taken within
2 days of the onset of the flu. These are prescription drugs that
only work on the flu virus. If a person has an illness caused
by another kind of virus or by bacteria, the medicines will not
be effective. These medicines are very expensive. If you have
questions please make an appointment with a provider.
