Why is the flow adjustment 14 days?

This is because the isolation period of infectious diseases is determined according to the incubation period of diseases. The incubation period of pneumonia infection in novel coronavirus is generally 3-7 days, and the longest is no more than 14 days, which is contagious.

If you receive a call from an epidemiological investigation, it may be that you have been in close contact with a confirmed or infected person recently, but you don't know where you have been, so the staff of the epidemiological investigation will ask you some information and trace the spread path of the virus.
