Medical institutions shall determine the isolation period for the pathogen carriers of Class A infectious diseases.

Class A infectious diseases include plague and cholera. According to the inquiry of 39 Health Network, the determination of isolation period needs to be comprehensively considered according to factors such as epidemic control, medical conditions, and risk of pathogen transmission. For serious infectious diseases such as plague and cholera, in order to effectively control the spread of the epidemic, the isolation period will be longer, usually several weeks or months.
