Flu Treatment

What to do if you get sick with the flu:

Stay home.

Should you become infected, keep the germs from spreading by staying home. Most people are contagious for 24 hours before symptoms appear and then for an average of 5-7 days after symptoms appear. During this time, try to limit exposure to others, especially those who are at greater risk of flu complications. People with flu are no longer contagious after they have no fever without the help of fever-reducing medications for 24 hours.


 

If you have influenza, drink lots of fluids to prevent dehydration

Drink fluids.

Drink plenty of water and other clear liquids to prevent fluid loss (dehydration).

Take antivirals if prescribed.

Take antivirals if they are prescribed.

Studies show that flu antiviral drugs work best for treatment when they are started within two days of getting sick. However, starting them later can still be beneficial, especially if the sick person is at high risk of serious flu complications or is in the hospital with more severe illness. 

Antiviral treatment is expected to lessen fever and symptoms and shorten the time you are sick. They also may reduce the risk of complications such as ear infections in children, respiratory complications requiring antibiotics, and hospitalization in adults.

Risk of Death

For people at high risk of complications, early treatment with an antiviral drug can mean having milder illness instead of more severe illness that might require a hospital stay. For adults hospitalized with flu illness, some studies have reported that early antiviral treatment can reduce their risk of death.
