早在1995年6月16日,世界卫生组织就在日内瓦提出警告说:登革热正在全球迅速流行。近些年来,其传播速度越来越快,范围越来越广,每年的发病率为数千万例,死亡率年均2万人左右。据估计,全球100多个国家中有26亿人可能受到传染。 登革热是由登革病毒引起的一种蚊媒急性传染病。病人是重要传染源,埃及伊蚊和白纹伊蚊则是主要传播媒介。埃及伊蚊是一种家蚊,孳生于室内清水容器中,如水缸、花盆等容器的积水中,成蚊嗜吸人血,对登革病毒的感染率甚高。白纹伊蚊除孳生于室内容器积水外,室外各种坛罐、树洞中皆可孳生。这两种蚊媒在我国都存在,我国人群对此病免疫力差,易被感染。1978年广东佛山市石湾镇发生的登革热流行,就是白
As early as June 16, 1995, the World Health Organization warned in Geneva that dengue fever is rapidly becoming widespread in the world. In recent years, its spread faster and faster, the scope is more and more widespread, the annual incidence of tens of millions of cases, the annual average of 20,000 deaths. It is estimated that 2.6 billion people in 100 countries around the world may be infected. Dengue is a mosquito-borne infectious disease caused by dengue virus. The patient is an important source of infection and Aedes aegypti and Aedes albopictus are the main vectors. Aedes aegypti is a domestic mosquito breeding in indoor water containers, such as water tanks, flower pots and other containers of water, adult mosquito suck blood, the rate of dengue virus infection is very high. Aedes albopictus in addition to breeding in the indoor container of water, outdoor altar jar, tree hole can be breeding. Both of these mosquito vectors exist in our country and our population is poorly immune to the disease and susceptible to infection. In 1978, the epidemic of dengue occurred in Shiwan, Foshan City, Guangdong Province, was white
