Abstract:
Objective:To investigate the hot spots and epidemiologic characteristics of hand, foot and mouth disease (HFMD) in Jinan municipality from 2009 to 2016.
Methods:Disease reports of HFMD in Jinan from 2009-2016 were collected and analyzed with ArcGis 10.2 to show the hot spot in different villages and towns, as well as clustering analysis and descriptive epidemiology to show epidemiologic characteristics.
Results:A total of 89 486 HFMD cases were reported and the reported annual incidence rate was 160.94/100000 during the 7-year period, which increased year by year, and within the whole city, each county was at a higher epidemic level; the curve of incidence is unimodal and the incidence peak occurred mostly between May and August, especially in June; 115 severe cases were reported and the ratio was 0.13%. Of the reported cases, 81.51% were between 1 to 4 years old; 60.36 % were children living scattered. The hot spots were like a circle surrounding the core areas, showing a tendency of increase; the proportion of EV71, CVA16 and other enteroviruses were 33.67%、37.22%and 29.09%, respectively, and they appeared in turn, but severe cases were mostly affected by EV71.
Conclusions:The HFMD in Jinan is in a highly prevalent level, with low ratio of severe cases. Seasonal(high in summer) and unimodal; more common among children between 1 to 4 years old, living scatted and in urban and rural linking areas, with the tendency of increasing of hot spots; prevalent pathogens appear in turn.
