Abstract:
Objective To investigate the positive detection and epidemic characteristics of enter ovirus(EV),the pathogen of hand-foot-mouth disease(HFMD),in Hangzhou,and to provide scientific basis for formulating prevention and control strategies of HFMD in the future.Methods From January 2016 to December 2022,14 259 positive cases of enterovirus universal nucleic acid detected in Hangzhou Children's Hospital were collected and analyzed retrospectively by age,gender,detection time and other factors.Results The average positive detection rate of EV was 45.48%(14 259/31 354),among which the positive detection rate of boys was 27.20%and that of girls was 18.28%,the difference was statistically significant(P<0.01).The positive detection rate of EV in children of different ages decreased with the increase of age,and the positive detection rate of EV in children under 5 years old accounted for 90.38%of all positive children.Seasonally,enteroviruses were detected throughout the year,but the incidence was high in summer,and the total positive number from May to July accounted for 49.16%of the total detected number.In terms of year,the positive detection rate of EV has shown a downward trend year by year since 2016.Conclusion There are gender differences in enterovirus infection in Hangzhou,and boys are more susceptible to enterovirus infection,especially children under 5 years old need to pay attention to EV protection.In addition,HFMD has a certain seasonality,with a high incidence in summer,and the annual detection rate has declined year by year since 2016,which may be related to the promotion of vaccines and the improvement of health awareness.
