What is West Nile Virus

West Nile Virus is a viral infection that is primarily transmitted to humans through the bite of infected mosquitoes. It was first identified in Uganda in 1937 and has since spread to various parts of the world, including North America, Europe, and Asia. The virus belongs to the flavivirus family and is closely related to other mosquito-borne illnesses such as dengue and Zika.

Most people infected with West Nile Virus experience no symptoms or only mild flu-like symptoms. However, in some cases, particularly in older adults and individuals with weakened immune systems, the virus can cause severe illness, including inflammation of the brain (encephalitis) or the membranes surrounding the brain and spinal cord (meningitis).

Prevention is key in reducing the risk of West Nile Virus. This can be achieved by using mosquito repellents, wearing protective clothing, and eliminating standing water where mosquitoes breed. There is currently no specific treatment for the virus, so medical care focuses on managing symptoms and providing supportive care.
