目的对2009-2010年深圳市某街道手足口病进行病原学监测分析。方法收集5440份手足口病患者的病原学监测资料,对资料进行描述性分析和χ2检验。结果总肠道病毒(EV71和CoxA16)阳性率为43.3%,其中EV71阳性率为19.4%,CoxA16阳性率为23.9%,二者差异无统计学意义(χ2=0.396,P=0.529)。男性总肠道病毒阳性率为44.7%,女性阳性率为41.4%,不同性别间肠道病毒阳性率差异无统计学意义(χ2=0.076,P=0.783)。各年龄段肠道病毒阳性率差异有统计学意义(χ2=4.241,P=0.039)。12名重症患者中,EV71阳性率75.0%。结论深圳市某街道2009-2010年手足口病流行的病原体为EV71和CoxA16,不同性别的阳性率无差别,各年龄段肠道病毒阳性率差异有统计学意义。
Objective To analyze the etiology of hand, foot and mouth disease in a street in Shenzhen in 2009-2010. Methods The etiological surveillance data of 5440 hand, foot and mouth disease patients were collected, and the data were analyzed descriptively and chi - square test. Results The positive rate of total enterovirus (EV71 and CoxA16) was 43.3%. The positive rate of EV71 was 19.4% and the positive rate of CoxA16 was 23.9%. There was no significant difference between the two (χ2 = 0.396, P = 0.529). The positive rate of total enterovirus in males was 44.7% and the positive rate in females was 41.4%. There was no significant difference in the positive rates of enterovirus among different sexes (χ2 = 0.076, P = 0.783). The positive rate of enterovirus in each age group was statistically significant (χ2 = 4.241, P = 0.039). Among the 12 critically ill patients, the positive rate of EV71 was 75.0%. Conclusion The prevalence of HFMD in a street in Shenzhen in 2009-2010 was EV71 and CoxA16. The positive rates of different sexes were not different. The positive rates of enterovirus in all age groups were statistically significant.
