[Epidemiological Characteristics of Hand, Foot, and Mouth Disease and the Effect of EV71 Vaccination in Chengdu from 2012 to 2020].

While continuing to promote EV71 vaccination in the future, Chengdu also needs to pay more attention to viral infection serotypes other than EV71 and Cox A16 and conduct research on multivalent vaccines against a variety of enteroviruses. The focus of prevention and control can be placed on areas with high population density, large floating populations, large numbers of agriculture-related communities, and insufficient individual awareness of hygiene. For the second circle of Chengdu city, the disinfection of agriculture-related communities should be strengthened, and information sessions or other health education activities could be organized for individuals and daycare facilities with low awareness of the importance of hygiene. In addition, more attention should be given to the prevention and control of HFMD in the high incidence seasons.
