Surveillance of Japanese encephalitis vectors, such as the appearance of the red house mosquito
[충청뉴스 권상재 기자] The Chungcheongnam-do Health and Environment Research Institute announced on the 28th that it will carry out a surveillance project from next month to the end of October to preemptively respond to and prevent Japanese encephalitis.
The survey will be used as basic data for issuing Japanese encephalitis advisories and warnings by examining the first appearance time and occurrence density of the small red house mosquito, which is a carrier of Japanese encephalitis.
The surveillance project is carried out by installing a pyloric light in a barn located in Sapgyo-eup, Yesan, collecting mosquitoes twice a week, and then checking for virus infection through mosquito classification and genetic detection tests.
A Japanese encephalitis warning is issued when the little red house mosquito is first discovered.
An alert is issued when there are more than 500 red house mosquitoes among the daily average number of mosquitoes collected twice a week and more than 50% of the total mosquito density ▲ Japanese encephalitis virus is isolated from the collected mosquitoes or the virus gene is detected Cases ▲ Japanese encephalitis cases are issued when one or more of the following occurs.
Japanese encephalitis is a zoonotic disease transmitted by mosquitoes infected with the Japanese encephalitis virus.
The incubation period is 4-14 days, and most people over 95% pass asymptomatically, but very rarely progresses to encephalitis. When encephalitis occurs, it leads to impaired consciousness, convulsions, and coma, and the mortality rate reaches 30%.
An official from the Provincial Health and Environment Research Institute said, “The distribution and habitat environment of vectors due to global warming are changing.” said.
