Arrival of the seasonal flu wave: vaccination, your best protection
For the fifth consecutive week, the number of flu cases declared by laboratories is continuously increasing. This week, the number of cases increased from 375 to 745, an increase of 99% compared to the previous week. This progression is part of a constant growth trend observed since week 47, when there were 60 cases, followed by 114 cases in week 48, 190 cases in week 49 and 375 cases in week 50. During the last five weeks , there were 82% influenza A and 18% influenza B among the typed results. Among influenza A virus samples, the subtypes identified are A(H1) pdm9 (46%) and A(H3) (54%).
These figures reconfirm the start of the annual wave of seasonal flu. The Ministry of Health and Social Security reminds that it is still possible to be vaccinated to protect yourself effectively and limit the spread of the virus. Vaccination remains the most reliable way to prevent seasonal flu and reduce the risk of associated complications.
How to protect yourself more against seasonal flu?
In addition to vaccination, it is essential to adopt barrier gestures to limit the spread of the virus:
- Wash your hands regularly with soap and water for 30 seconds, scrubbing palms, fingers, backs of hands and under nails thoroughly.
- Cover your mouth and nose with a tissue when you cough or sneeze. If you don’t have a tissue, use the crook of your elbow.
- Throw used tissues in the trash immediately and then wash your hands.
- Avoid physical contact such as hugs, kisses and handshakes.
- Avoid crowds and gatherings during the epidemic season.
- Stay home if you are sick to avoid contaminating those around you.
- Ventilate the rooms regularly, at least 3 to 4 times a day for 10 minutes.
By following these simple actions, you help protect your health and that of others.
