The Chungnam Provincial Institute of Health and Environment announced on the 28th that the small red house mosquito, a vector of Japanese encephalitis, was discovered for the first time this year in the region.


The timing of this year's discovery of the small red house mosquito is about two weeks earlier than last year.


The small red house mosquito measures 4.5 mm and has a dark brown color. It mainly inhabits rice paddies, puddles, and livestock barns, and feeds on animals and humans at night by biting their bodies.


Japanese encephalitis is a viral zoonotic infectious disease, with an average of 18 cases occurring annually in South Korea over the past five years.


Most infected individuals are asymptomatic, but 1 in 250 progresses to acute encephalitis. Among those who develop acute encephalitis, 20 to 30% may die, so caution is required.



Kim Ok, director of the Chungnam Provincial Institute of Health and Environment, said, “There is still no appropriate treatment developed for Japanese encephalitis,” and urged, “At home, use window screens or mosquito nets, and at night, avoid outdoor activities or use mosquito repellents to prevent mosquito bites.”
