Influenza (also known as the flu) is a highly contagious illness for all ages and is spread easily from person to person by coughing, sneezing, or touching contaminated surfaces.
- Fever (temperature higher than 37.8ºC) that lasts 2-5 days
- Headache and muscle aches
- Cough and sore throat may also be present
Flu symptoms usually improve in 2-5 days but can persist for up to a week or more. Most people with the flu recover within one to two weeks without treatment. Pneumonia is the most common complication of the flu virus.
Getting vaccinated against Seasonal Influenza is the most effective way to prevent and control epidemics.
