First, public transport.
The first is public transport, which is a hidden transmission chain, because for positive patients, they have taken some means of transport such as motor trains or planes before, and these areas are very dangerous if they are not killed in time, which will cause subsequent crowd infection.
Second, close contacts.
Followed by close contacts, for close contacts, some of them are infected, but they are infected without knowing it, so this situation may be transmitted to other healthy people, so beware of close contacts.
Third, the positive patient has been to that area.
In addition, the areas where positive patients have been are also very dangerous for the people. After all, positive patients themselves carry the virus, and they will leave their own virus in the corresponding area, which may lead some healthy people to reach the corresponding area and be directly infected with the corresponding virus.
Fourth, the sewer area
Furthermore, the sewer area is also a dangerous area. For many people, there may be some excrement of positive patients in the sewer area, so these areas are inaccessible, and sewage treatment workers may be infected with the corresponding virus, which is very fatal.
