The virus was first detected in the U.S. in 1999 after two men in New York City tested positive for the virus, which it is believed first arrived in the country through an infected mosquito or bird.
So far, over 200 cases of West Nile have been detected nationwide in 2024, according to CDC data.
What are the symptoms of West Nile virus?
Approximately 80% of the people infected with WNV will not develop any symptoms. 20% will experience mild flu-like symptoms such as fever and less than 1% will develop severe long-term effects which sometimes can be deadly, according to HHS.
The symptoms include:
- Body aches
- Diarrhea
- Fever
- Headache
- Vomiting
Among the most serious complications are meningitis, paralysis or death.
When do West Nile symptoms start to show?
Symptoms generally appear between two to 14 days after being bitten but sometimes it could be several weeks before symptoms show up in immunocompromised people, according to the CDC.
How to cure West Nile virus?
According to the CDC, there is no specific treatment for West Nile virus though doctors usually recommend pain medication for headaches and antiemetic therapy and rehydration to treat nausea and vomiting.
How to protect yourself from West Nile virus?
The best way to protect yourself from West Nile is to dress in loose-fitting clothing that covers arms and legs when outside. Using air conditioning and adding screens to open doors and windows is also recommended.
