海南省陵水县1980年7月发生登革热流行,疫区主要分布在以埃及伊蚊占优势的新村、长城及黎安等3个滨海墟镇,流行一直延续至1981年8月。陵水县陵城镇地区经4次媒介调查,均未发现埃及伊蚊,而以白纹伊蚊为主。当时,对920名居民逐户进行登记,920名居民中,有典型登革热表现者9人,患病率为9.79‰,其中县防疫站和县医院发病较高,为17.47‰,流行强度较轻,呈散发水平。在继发患者宿舍中捕到白纹伊蚊。继发病例均排除了患者病前1个月内曾到过其他登革热疫区感染的可能性。对15例继发登革热患者康复期作了中和试验,结果表明,15份康复期血清中12份登革Ⅲ型抗体阳性,确诊率为80%。1980年9月至1981年10月我们先后4次对陵城镇以及附近的椰林乡和三才镇进行媒介调查,结果均没有发现埃及伊蚊,
The dengue epidemic occurred in July 1980 in Lingshui County, Hainan Province. The epidemic areas were mainly distributed in three coastal villages such as Xincun, the Great Wall and Li’an, which are dominated by Aedes aegypti. The epidemic continued until August 1981. After four media surveys in the Lingcheng area of Lingshui County, no Aedes aegypti, but Aedes albopictus was found. At that time, 920 residents were registered household by household. Among the 920 residents, 9 were typical dengue fever with a prevalence of 9.79 ‰. Among them, the county epidemic prevention station and county hospital had a higher incidence of 17.47 ‰ with mild epidemic intensity , Was distributed level. Aedes albopictus is caught in secondary patient quarters. Secondary cases were excluded from the patients within 1 month before they had been infected with other dengue epidemic possibility. Neutralization test was conducted on 15 cases of secondary dengue fever during rehabilitation period. The results showed that 12 dengue Ⅲ antibodies were positive in 15 convalescent sera with a diagnosis rate of 80%. From September 1980 to October 1981, we conducted media surveys on the towns of Lingcheng, nearby Coconut Township and Sancai Township four times in succession. In the end, we found no evidence of Aedes aegypti,
