Influenza is an acute respiratory infectious disease caused by the influenza virus, and can occur all year round. The peak season of influenza epidemics varies in different regions in China. The high incidence period of influenza in northern China is autumn and winter, while in southern China it is spring and summer.

On hot summer days, the air is not circulating in air-conditioned indoor areas, which makes it easy for the virus to spread. In addition, the temperature difference between indoor and outdoor areas may also cause flu symptoms, such as high fever, myalgia, fatigue, cough, etc.

The influenza virus is highly contagious and spreads rapidly. According to the World Health Organization, it can cause 5% - 10% of adults and 20% - 30% of children to get flu every year, which means that one in ten people will be infected with influenza in the flu season.

Some people may develop severe influenza due to complications such as pneumonia.

How to effectively prevent influenza?

Vaccination is the most effective way to prevent influenza.

Other preventive measures include:
Avoid going to crowded places with poor ventilation during the flu season;
Wear masks and wash hands frequently;
Maintain good indoor ventilation and regular disinfection.

How does the influenza virus spread?

The influenza virus is mainly transmitted through droplets created by sneezing and coughing, and can also be transmitted through mucous membranes in the mouth, nose and eyes. Touching items contaminated by the virus can also cause infection.

The symptoms caused by influenza are more severe than those of the common cold. If you have obvious symptoms such as high fever, pain, fatigue and cough, you need to seek medical help as soon as possible. Timely use of anti-influenza medicine under the guidance of a doctor can alleviate the severity of the infection.
