Prevention of toxic bacillary dysentery includes managing the source of infection, cutting off the transmission route and protecting susceptible populations.
Managing the source of infection is mainly about managing and thoroughly treating patients with acute and chronic dysentery as well as carriers to prevent them from spreading the pathogen.
In terms of cutting off the transmission route, the main objective is to maintain good hygiene, wash hands regularly, pay attention to dietary hygiene and fly control to reduce the transmission vector.
For protection of susceptible persons, immunity is currently established in China by means of oral live vaccination, but there is no cross-protection between different types of Shigella, and recurrent or repeated infections are desirable.
