Abstract

Abstract

Objective To describe the epidemiological characteristics of hand, foot and mouth disease (HFMD) and explore the spatial-temporal change tendency from 2009 to 2018 in Shaanxi Province. Methods The descriptive statistic method was used to describe epidemic situation of HFMD and moving epidemiological method (MEM) was used to detect the epidemic season, and possible spatial-temporal clusters of HFMD among down towns in Shaanxi Province from 2009 to 2018. Results The average morbidity from 2009 to 2018 was 143.01 per 100 000.The male-female ratio of HFMD was 1.47:1. The age of patients ranged from 1 day to 80 years old and the median age was 2 years old. The incidence of HFMD was increasing generally from 2009 to 2018, and from the end of April to July every year was the peak of HFMD in Shaanxi Province. The results from MEM model showed that the incidence of HFMD exceeded the given threshold value of low epidemic situation at 19th week, then reached to medium epidemic situation in the next week and lasted for 11 weeks. After that, the incidence rate came down back to low epidemic and normal situation at 31th and 33 th week respectively in the year of 2018. The results from the space-time scanning analysis showed that the epidemic period was from April 2010 to July 2010 from the time dimension, and some counties in Xi'an, Xianyang and Weinan (RR=5.71, 95% CI: 5.70-5.73, P < 0.001) were the main gathering areas of HFMD, and the main gathering areas were relatively fixed in 10 years. Conclusions There are significant spatial-temporal cluster patterns for the distribution of HFMD incidence in Shaanxi. The Guanzhong area is the main gathering area. The prevention and control intervention should be strengthened accordingly.
