West Nile Virus


West Nile Virus (WNV) was first identified in the West Nile sub-region in the East African nation of Uganda in 1937

West Nile virus is caused by a bite from an infected mosquito that's already carrying the virus, but it's important to remember that not all mosquitoes are infected,it is a mosquito-borne zoonotic arbovirus belonging to the genus Flavivirus in the family Flaviviridae. This flavivirus is found in temperate and tropical regions of the world. In many parts of the United States, the risk of being bitten by an infected mosquito is greatest from July to early September. But in some parts of the country, mosquito bites can be a risk all year long.


Not everyone who gets bitten by an infected mosquito will get the virus, from studies we know that only about one in every five people who get infected with West Nile will actually develop symptoms.

The most common ones are
- Fever
- Headaches
- Body ache
- Joint pain
- Vomiting
- Diarrhea
- Rash

A lot of people who develop symptoms usually just wait it out at home. Or they’ll go to a medical doctor and end up recovering from their illness and feeling much better within several weeks. Sometimes, people will complain of fatigue or report feeling not quite themselves for several months.


If they think they have West Nile, they can have their blood tested for the presence of antibodies or, in more severe cases that affect the central nervous system, a doctor can take samples of the cerebrospinal fluid that surrounds the brain and spinal cord.Usually people are hospitalized if they have more serious symptoms.West Nile virus is not spread from person to person.
