目的了解深圳市出口加工区健康人群登革热抗体水平,为制定登革热防治对策提供依据。方法 2014年10月,在深圳市出口加工区随机抽取17~60岁健康人群508人进行血清登革热病毒Ig G抗体水平检测。结果检测508人中,登革病毒Ig G抗体阳性的14人,阳性率为2.76%。登革病毒Ig G抗体阳性率,男性为2.15%,女性为5.56%,男女比较差异无统计学意义(χ2=3.19,P>0.05);17~25岁阳性率为2.61%,26~35岁为2.23%,36~60岁为3.55%,各年龄组比较差异无统计学意义(χ2=0.64,P>0.05)。不同职业和文化程度间登革病毒Ig G抗体阳性率差异也均无统计学意义。结论深圳市出口加工区及周边片区健康人群中登革病毒抗体阳性率较低,提示一旦存在输入传染源,则有登革热暴发疫情的可能。建议积极开展预防登革热的宣传教育,加强登革疫情和媒介监测,完善登革热防控体系。
Objective To understand the level of Dengue antibody in healthy population in Shenzhen Export Processing Zone and provide evidence for dengue fever prevention and control measures. Methods In October 2014, 508 people from 17 to 60 years of age in the export processing zone of Shenzhen were randomly selected for serum IgA antibody detection of Dengue virus. Results Among the 508 tested persons, 14 were positive for dengue virus Ig G antibody, with a positive rate of 2.76%. The positive rate of dengue virus Ig G antibody was 2.15% in males and 5.56% in females, there was no significant difference between males and females (χ2 = 3.19, P> 0.05). The positive rates of dengue virus Ig were 2.61%, 26-35 (2.23%) and 3.55% (36-60 years). There was no significant difference among all age groups (χ2 = 0.64, P> 0.05). There was no significant difference in the positive rate of dengue virus Ig G antibody between different occupations and educational levels. Conclusions The positive rate of dengue virus antibody in healthy population in Shenzhen Export Processing Zone and surrounding areas is low, suggesting that there is a possibility of an outbreak of Dengue outbreak once the source of infection is imported. It is suggested that publicity and education on dengue fever be actively carried out, the epidemic of dengue and media monitoring be strengthened, and the dengue fever prevention and control system should be perfected.
