Infectious diseases are classified into A, B, and C in China based on nature, transmission channel, and speed. The most pandemic diseases -- including plague, cholera, and SARS -- fall into the Category A. Category B diseases spread in less easy channels and at a lower speed, including typhoid fever, dengue fever, and scarlatina. Category C is for the least infectious, including tuberculosis, snail fever, mumps, and leprosy.
