There is also a risk of re-infection within a short period of time after recovering from the flu, but this depends on the individual’s constitution.
Within a short period of time after recovering from influenza, you may be re-infected if you come into contact with disease-causing factors again. Since the influenza virus does not form a lifelong immunity in the body after recovery, it cannot be ruled out that one may be infected again.
However, the chance of re-infection depends on the individual’s physical condition. People with relatively strong resistance have a relatively low rate of re-infection; if their own antibodies are relatively weak, the chance of re-infection will be higher.
In order to minimize the chance of being re-infected with influenza, it is necessary to take good care of yourself on a daily basis. The windows of your room need to be opened frequently for ventilation to keep the air convected. During the flu season, you should reduce the number of times you go to public places, try to wear a good mask in crowded places, and wash your hands frequently after you go home. If you still have fever, cough and other symptoms, you need to consult a doctor in time.
