Q: How to prevent aerosol transmission?
A: In a relatively closed environment and exposed to high concentrations of aerosols for a long time, aerosol transmission is possible, but not the main mode of transmission.
This reminds medical staff and researchers that when working in some special environments, they should pay attention to the protective measures of air isolation.
But the general public does not have to worry too much about it, just open the windows at home and ventilate.
Q: Does it matter that the sewer is open?
A: Unblocking of the sewer is extremely important! Previously, a team had discovered the COVID-19 in the feces.
