How Mosquitoes Transmit Encephalitis
Certain mosquito species transmit encephalitis-causing viruses to humans through bites. The viruses, including West Nile, Japanese encephalitis, and Eastern equine encephalitis, circulate between birds or animals and mosquitoes. When an infected mosquito bites a person, it can pass the virus, potentially leading to brain inflammation.
Symptoms and Health Risks of Mosquito-Borne Encephalitis
Symptoms often include sudden fever, headache, confusion, seizures, and altered consciousness. In severe cases, encephalitis can cause long-term neurological problems or death. Mild infections may go unnoticed, while others require hospital care and supportive treatment.
Prevention and Key Facts
Reducing mosquito exposure lowers the risk of encephalitis. Use EPA-registered repellents, wear long sleeves, and install window screens. Eliminate standing water where mosquitoes breed.
