Analysis the Examination Results of Foot-Hand-Mouth Disease in Pudong New District of Shanghai, 2013

OBJECTIVE To know difference of the epidemiological and etiological characteristics of Hand- Foot-Mouth Disease （HFMD）between 2013 and 2012 in Pudong New District of Shanghai. To provide lab basisfor the FHMD control and prevention. METHODS 293 samples were collected from the HFMD patients. Samples were detected by real-time PCR for enteroviris 71, coxsackie 6, coxsackie 10 and coxsackie 16. RESULTS The detection rate of HFMD was 59.25%, which was higher than that of 2013. The constituent ratio of EV71, CAI6, CA6, CA10 and other enterovirus were 21.39%, 19.08%, 38.73%, 2.31% and 33.66%, respectively. HFMD was prevalent all the year and the epidemic peak was in June. Children from 2 to 5 were easy to catch the HFMD in the kindergarten. The male to female ratio of the positive cases was 1.60：1. CONCLUSION CA6 was the main subtypes to cause the HFMD in Pudong New District of Shanghai in 2013. It is suggested that the surveillance and detection new subtypes of HFMD should be enhanced.
