There are currently three known ways of transmission of COVID-19, mainly through respiratory droplet transmission, close contact transmission and aerosol transmission.
- Droplet transmission is a type of airborne transmission. Droplets stay in the air for a long time and can cause infection when inhaling air containing COVID-19。
- Contact transmission is when contact with the secretions of a confirmed patient/suspected patient as an asymptomatic carrier, such as sputum, saliva, blood, feces, and urine may be transmitted.
- If exposed to high concentrations of aerosols for a long time in a relatively closed environment, there may also be the possibility of aerosol transmission
Viruses and bacteria from sneeze can be at speeds of up to 100 miles per hour,which will disperse into more than 40,000 individual droplets (the droplets contain a lot of viruses and bacteria).
By the way,sneezes can hit 8 meters away,and the virus can be suspended for 24 hours.What’s more, if there is air current, the sneeze can spread to 40m, and the smaller drops can still exist when you get in the car in next time!
So be sure to wear a mask !!!
Even if you are in contact with an infected person, wearing a mask can prevent you from directly inhaling the virus in the droplets.
Be sure to wash your hands frequently! Even if the virus is left on your hands, washing your hands can block the virus from entering the body through your hands.
