How is a cold transmitted?

Cold is transmitted by droplets, direct contact, indirect contact, etc.

1. Droplet transmission

pathogens can be transmitted into the air through droplets released by patients coughing and sneezing, and suspended in the air for a period of time. If healthy people inhale droplets containing viruses, they may be infected with cold.

2. Direct contact

If healthy people and patients shake hands, hug, share items, etc., pathogens in patient body secretions can be transmitted to healthy people, resulting in infection.

3. Indirect contact If

healthy people touch door handles, elevator buttons, handrails of public transportation vehicles, etc. carrying pathogens, and then do not wash them in time, they may touch their eyes, nose, and mouth, which may cause pathogens to be brought into their own bodies and cause infection.
