Transmission routes of influenza

Influenza, commonly known as the flu, mainly spreads through droplet transmission, direct contact transmission, and indirect contact transmission. Droplet transmission is the most common way the flu spreads. When an infected person coughs, sneezes, or talks, virus-containing droplets are released into the air, and susceptible individuals can become infected by inhaling these droplets. Additionally, direct contact transmission should not be overlooked; close interactions such as shaking hands, hugging, or kissing someone with the flu can directly transmit the virus. Indirect contact transmission refers to touching objects contaminated by the virus, such as utensils, drinking cups, or towels previously used by an infected person, which can also lead to virus transmission.

To prevent the flu, the following measures are recommended:

1. Maintain personal hygiene and wash hands frequently;

2. During flu season, try to avoid going to crowded and poorly ventilated places;

3. Wear a mask when going out to reduce the risk of droplet transmission;

4. Exercise regularly to strengthen physical condition and improve immunity.

Furthermore, if flu symptoms appear, seek medical attention promptly and follow the doctor's advice for treatment to avoid worsening of the illness and reduce the risk of transmitting it to others.
