| Abstract: |
1980年海南岛发生登革热大流行,疫情波及13个县122个区,发病率为2146.23/万,死亡64人。次年仍在局部地区出现流行,1982年仅发生个别病例而流行告终。
从流行区的埃及伊蚊体内分离出6株病毒,从白纹伊蚊体内分离出3株病毒,从致乏库蚊体内分离出2株病毒,从127例急性期病人的血中分离出87株病毒。所有这些新分离到的病毒经鉴定都是Ⅲ型登革病毒。流行病学调查和病毒分离结果证明,埃及伊蚊是在海南岛传播登革热的主要媒介。 |

A large epidemic of dengue fever occurred in Hainan Island in 1980. It involved 13 counties including 122 districts. The morbidity was 2146.23 per ten thousand population and 64 persons died due to this desease. Epidemic still occurred in local areas in 1981. But only occasional cases were found in 1982 and the epidemic ended.
Six virus strains were isolated from Aedes aegypti in epidemic area, 3 from Aedes albopictus, 2 from Culex fatigans and 87 from acute-phase sera of 127 patients. All these virus strains were identified as Type Ⅲ dengue virus. Results of epidemiological investigation and virus isolation proved that Aedes aegypti served as the main vector for the transmission of dengue fever in Hai nan Island. |
