Preventing influenza infection

Influenza tends to spread from December to March, and when it does spread, it can infect many people in a short period of time.
To prevent infection, be sure to wash your hands with soap, wear a mask when you have a cough or go out in a crowd, ventilate the room frequently, etc. Also, if you suspect you have influenza, be sure to visit a medical institution as soon as possible and avoid going out if necessary to avoid spreading the virus to others.
