Influenza or « flu » is a viral seasonal illness that affects the respiratory tract. Influenza occurs globally with an annual attack rate estimated at 5%–10% in adults and 20%–30% in children. Flu activity is currently (February, 3rd) widespread in most of the United States.

Influenza viruses can be especially dangerous for people over 65, among others. Epidemics are more likely to spread in collective accommodations (retirement homes, nursing homes…).

How can influenza and its complications be recognized and prevented?

What are the symptoms of flu?

The symptoms of flu can last from a day to two weeks. They appear in the form of:

• Fatigue, muscle soreness,
• Fever, chills,
• Headaches, sore throat, sneezing,
• Dry coughing, runny nose and chest pain,
• In some cases, nausea and vomiting.

You’ll need to consult your general practitioner as soon as the first symptoms appear.

   • By reducing your consumption of caffeine, sugar and alcohol.
   • Work out on a regular basis.
   • Sleep well.
