COVID-19 route of transmission

1. Droplet spread: droplets produced by coughing, sneezing, talking, etc., enter the surface of the susceptible mucosa.

2. Contact spread: touching one's own mouth, nose or eyes after touching something that has been touched by the infected person leads to the spread of the virus;

3. Airborne: pathogens can still be contagious after long-term and long-distance spread.

4. Fecal-oral spread: rotavirus, which exists in patients' feces, often pollutes water, food, clothing, toys, appliances, etc., when healthy people come into contact with these items, they will enter the human body through hand and mouth, causing digestive tract lesions.

If you live in an environment where patients have been diagnosed, or if you live in densely populated urban areas, it is also necessary to wear masks outside.
