West Nile Virus (WNV) is a mosquito-borne illness that can affect anyone. Most infected people show no symptoms, but about 1 in 5 may develop a fever with symptoms like headaches, body aches, joint pains, vomiting, diarrhea, or a rash. People over 50 are more likely to get sick and experience severe symptoms. Prevention is crucial! Protect yourself from mosquito bites by using repellent and wearing long sleeves.
