This detailed photo shows a mosquito feeding on human skin, visually representing the main cause of Japanese encephalitis. The disease is caused by the Japanese encephalitis virus (JEV), which is transmitted to humans through the bite of infected Culex mosquitoes. These mosquitoes typically breed in rice paddies and wetlands and are most active at night. While the virus primarily circulates among pigs and water birds, humans can become incidental hosts. The image emphasises the importance of mosquito control, repellents, and vaccination in preventing the spread of this serious brain infection.
