West Nile Virus
West Nile Virus
West Nile Virus (West Nile fever, West Nile encephalitis) is a virus that is primarily transmitted by mosquitoes. Pronounced as /wɛst naɪl ˈvaɪrəs/, the virus is named after the West Nile district in Uganda, where it was first identified in 1937.
Etymology
The term "West Nile Virus" is derived from the West Nile district in Uganda, where the virus was first isolated in 1937. The virus was identified in an adult woman who was living in the West Nile district of Uganda at the time.
Transmission
West Nile Virus is primarily transmitted through the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds, which often carry the virus. Infected mosquitoes can then spread the virus to humans and other animals when they bite.
Symptoms
Most people infected with West Nile Virus do not have symptoms. About 1 in 5 people who are infected develop a fever and other symptoms such as headache, body aches, joint pains, vomiting, diarrhea, or rash. Less than 1% of infected people develop a serious, sometimes fatal, neurological illness.
Prevention
Prevention methods for West Nile Virus include using insect repellent, wearing protective clothing, and making sure windows and doors have screens to keep mosquitoes out. It's also important to empty standing water from outdoor items like buckets, gutters, pools, and bird baths to reduce mosquito breeding grounds.
