Abstract:
Objective To understand the epidemic characteristics of different virus types of hand, foot and mouth disease (HFMD) in Zhaotong City, and provide guidance and recommendations for the prevention and control of HFMD, and to analyze seasonal characteristics of different virus types of HFMD in Zhaotong City. Methods The epidemiological characteristics of different virus types of HFMD in Zhaotong City from 2014 to 2017 were analyzed using the concentration and circular distribution methods. Results The main pathogens detected were EV71, Cox A16 and other enteroviruses, which were 216, 182, and 294, respectively, accounting for 57.45%, 73.44%, and 67.11%. M was 0.86, indicating that EV71 had strong seasonality. The Rayleigh test showed statistically significant differences (Z = 99.53, P <0.001). ā = 157 °, the peak day of onset was May 10, similar to untyped (May 16), the peak period was April 21-June 1, and the epidemic period was April 1-June 21. Conclusion According to the incubation period of hand-foot-mouth disease and the period of time during which the vaccine develops protective effects, vaccination of hand-foot-mouth disease vaccine at the peak period has a good guiding significance for the timeliness and pertinence of vaccination.
