With the arrival of midsummer, the mosquitoes are breeding rapidly, which has brought troubles to people's lives and even threatened their health. For example, a common insect-borne infectious disease in summer, the Japanese encephalitis, is worthy of vigilance.

Epidemic encephalitis Japanese (abbreviated as Japanese encephalitis) is a natural epidemic disease caused by Japanese encephalitis virus, which is transmitted by mosquitoes and has been distributed in Asia. It is prevalent in summer and autumn, mainly transmitted by mosquito and insect bites, and is not contagious between people. Mosquitoes are the main transmission medium. Some species of Culex, Aedes and Anopheles can transmit this disease, among which Culex tritaeniorhynchus is the most important transmitting channel. The virus in mosquitoes can pass through eggs to survive the winter and can become a long-term storage host for the virus. Clinically, the disease is characterized by symptoms of central nervous system infection such as high fever, vomiting, drowsiness, convulsions, and impaired consciousness. Japanese encephalitis is the primary cause of viral infection and disability of the nervous system in Asian children. In recent years, the incidence of Japanese encephalitis in adults has also tended to increase. Some patients have serious sequelae, and the mortality rate of severe patients is high. To prevent it, it is mainly necessary to strengthen mosquito control and mosquito prevention, as well as vaccinate susceptible populations.
