摘要
目的加强登革热的监测,调查疫区内登革热的感染状况。方法采集曾发生登革热流行疫区内健康人群血清,应用间接免疫荧光试验检测血清中特异性抗登革热IgG抗体。结果埒西一四村登革热IgG抗体阳性率占5·02%(11/219),人群分布以老年人为主,各年龄组抗体阳性率差别有极显著统计学意义(χ2=45·071,P<0·001);西区长洲村IgG抗体阳性率占3·00%(3/100)。结论健康人群中存在登革热隐性感染者,是引起登革热流行的重要隐患。
Objective To observe infectious status of dengue fever virus and monitor the levels of antibody against dengue fever in the population of Zhongshan City. Methods Enzyme - linked immunosorbent assay （ELISA） was used for detection of IgG antibodies to dengue fever virus. Results Positive rates of IgG to dengue fever virus in the villages of Zhongshan City were from 3.00% to 5.02%. There were statistically significant differences among different age groups （x^2 = 45.071, P 〈 0.01 ）. Conelusion There are recessive dengue fever virus infection in the area and effective measures, such as the management of mobile population, be taken to control the prevalence of the disease.
