What is the Primary Transmission Route of Influenza?
The main transmission routes of influenza are respiratory transmission, which can spread droplets into the air through sneezing and coughing, thus infecting people nearby. Therefore, when family members contract influenza, it is best to isolate them, wear masks regularly, and also be aware that influenza can also be transmitted through contact and mother-to-child transmission. It is essential for everyone to maintain hygiene, wash hands frequently, and sanitize the home regularly.
1. Respiratory Transmission: Influenza viruses can be spread into the air through droplets produced by sneezing and coughing, which adhere to daily living items. Face-to-face close contact between people or contact with items contaminated by influenza viruses can lead to infection. Influenza viruses are sensitive to common disinfectants and ultraviolet light, and they primarily infect through the respiratory and digestive systems.
2. Contact Transmission: The mucus, saliva, and sputum of patients can contaminate surrounding objects, and normal people can be infected through contact with contaminated objects.
3. Contact Transmission: Close contact and intimate behavior between spouses, children, and relatives can lead to infection. During influenza outbreaks, it is recommended to wear masks when going out, wash hands frequently, and maintain personal hygiene to effectively prevent influenza virus infection.
Influenza can also be transmitted through air droplets. When people with influenza cough, sneeze, or speak loudly, the virus can be sprayed into the surrounding air along with droplets. Normal people can be infected when the virus enters their nasal mucosa during breathing. Indirect contact with dust and daily items can also lead to transmission. Influenza patients are the main source of infection, and they are contagious from the incubation period. The infectivity is strongest within 3 days of onset. Therefore, people with influenza should avoid crowded places, be isolated, and prevent infecting others and cross-infection.
