[Study on infectious diseases in Guizhou during the Republic of China].

There are many infectious diseases in Guizhou Province during the Republican period, including cholera, smallpox, typhoid, typhus, dysentery, scarlet fever, diphtheria, epidemic cerebrospinal meningitis, recurrent fever, malaria, trachoma, acute conjunctivitis, skin diseases, venereal diseases, leprosy and so on. Natural and social factors together led to the prevalence of infectious diseases during that period. For example, natural factors mainly include Guizhou province's special geographical condition and its frequent flood disasters, and social factors such as the unhealthy lifestyle and low medical level have also caused bad effects. In general, infectious diseases during the Republican period have resulted in a large number of mortalities and great financial losses, hindering the development of Guizhou economic society at that time.
