摘要：
Dengue fever (DF) is often asymptomatic in endemic areas. Asymptomatic infection during a DF outbreak in China, where DF is not endemic, has not been reported until now. In this study a total of 365 subjects from 6 villages were recruited from October 4-7, 2009. Overall, 102 subjects (27.95%) were positive for dengue virus (DENV) IgM, and 14 subjects (3.84%) were positive for DENV IgG and IgM. In different age groups, seropositive rates varied from 12.50% to 50.00% for DENV IgM, and from 0% to 11.76% for DENV IgG. Seroprevalence of DENV IgM was significantly higher than that of DENV IgG. Seroprevalence rates of DENV IgM differed among different villages. However, the seroprevalence of DENV IgM was not statistically significantly different among gender and age groups. Asymptomatic DF infection is prevalent in non-endemic areas.
