Abstract:
Objective:To understand the morbidity and epidemiological characteristics of hand, foot and mouth disease (HFMD) in Xianyang in order to provide evidence for making prevention strategies.
Methods:The incidence data of HFMD from 2013 to 2016 were collected from the National Disease Information Management System. The HFMD specimens were tested by polymerase chain reaction (PCR) and the results were analyzed by the Statistical Product and Service Solutions (SPSS19.0).
Results:A total of 29 662 HFMD cases were reported in Xianyang from 2013 to 2016, and the average annual incidence rate was 143.62/100 000, including 406 severe cases and 4 deaths. There were statistically significant differences in incidence rate among the four years (P<0.01). The peak of the incidence occurred in April to July, and the second peak occurred in October to November. The top three counties which had high incidence were Wugong, Xunyi and Jingyang. There were statistically significant differences in different counties (P<0.01). The age group of 0-3 year scattered children has the most reported cases, a total of 26 399 cases, accounting for 89.00%. The number of male cases was higher than that of female cases and there were statistically significant differences between male and female (P<0.01). A total of 2 439 samples of HFMD were detected in the laboratory, the positive rate was 47.23%, among which coxsackievirus type 6 (CV-A6), coxsackievirus type 16 (CV-A16) and enterovirus A71 (EV-A71) were 38.02%, 29.91% and 21.01%.
Conclusions:The HFMD morbidity had obvious seasonal trend. Regional and demographic characteristics of morbidity were significant in Xianyang. The dominant pathogen was different from 2013 to 2016. The EV-A71 is easy to induce the epidemic of the HFMD.
