Aedes aegypti is an important vector of dengue fever. Aedes aegypti is widely distributed and breeds in Africa, Central and South America, Australia and Southeast Asia. Aedes aegypti has been found in coastal areas south of latitude 22, such as Guangdong, Guangxi, Xishuangbanna and Hainan.
In September, 2006, when the personnel of Haikou Port Inspection and Quarantine Bureau carried out sanitary supervision on an imported Vietnamese ship, they found that there was water in an old iron drum on the stern deck, which contained a large number of young mosquitoes, eggs and larvae. The staff conducted technical identification of these young mosquitoes in time and confirmed that these insects are the main biological vectors for spreading dengue fever.
Extended data:
Aedes aegypti is the main vector of dengue fever in Hainan province. The investigation found that the density of Aedes aegypti, especially Aedes aegypti, in some cities and counties of Hainan Province was very high, while the density of Aedes albopictus, which was mainly bred outdoors, further increased due to continuous rainfall.
In addition, 15 there was no dengue fever epidemic in Hainan province, and the antibody level of the population was extremely low. If there are imported cases of dengue fever, it is very likely that there will be an epidemic. Because dengue fever has no specific drug treatment and vaccine protection, once it is prevalent in Hainan Province, it will seriously endanger people's health and economic and social development.
In 2002, the distribution of Aedes aegypti in Yunnan Province was first reported in Ruili City, Yunnan Province.
