West Nile fever
West Nile fever is a mosquito-borne infectious disease caused by the West Nile virus. The virus is primarily transmitted through the bite of an infected mosquito.
Pronunciation
West Nile fever is pronounced as "west nile fe-ver".
Etymology
The disease is named after the West Nile district in Uganda where the virus was first isolated in 1937.
Symptoms
Most people infected with the West Nile virus do not have symptoms. About 20% of people who become 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.
Diagnosis
Diagnosis is typically based on symptoms and blood tests.
Treatment
There is no specific treatment for West Nile fever. Over-the-counter pain relievers can be used to reduce fever and relieve some symptoms. In severe cases, patients often need to be hospitalized to receive supportive treatment, such as intravenous fluids, pain medication, and nursing care.
Prevention
Prevention involves reducing mosquito populations and avoiding bites. This may be done by eliminating standing water where mosquitoes breed and using insect repellent or wearing protective clothing.
