Infectious diseases in China are divided into three categories: A, B and C, which are differentiated according to their modes of transmission, speed of transmission, degree of harm to human beings and intensity of state control. There are only two kinds of Class A infectious diseases, plague and cholera, which are highly contagious and have a high mortality rate, and belong to the infectious diseases controlled by the state. The mortality rate of Class B infectious diseases is not as terrible as that of Class A infectious diseases, but it also needs strict management. Class B infectious diseases need to be prevented and controlled in strict accordance with relevant regulations and prevention and control plans. Class B infectious diseases usually have the same characteristics. If there are pathogens, each infectious disease has its own specific pathogens, including viruses, bacteria, fungi, spirochetes, protozoa and so on. And it is contagious. The infection intensity is related to the species, quantity, virulence and immune status of susceptible population.
