Virus Symptoms

According to the Centers For Disease Control and Prevention (CDC), roughly 80 percent of people infected by West Nile Virus do not show any symptoms. Milder symptoms, including fever, headache, body aches, nausea and vomiting, are common among the roughly 20 percent who do show symptoms.

While the vast majority of infected people show no symptoms, about one in 150 may develop severe symptoms. These can include high fever, disorientation, coma, muscle weakness, vision loss, numbness and paralysis, according to the CDC.

Adults older than 50 are more at risk of developing serious symptoms, and should be more cautious about avoiding mosquito bites.

Prevention Tips

When it comes to personal protection, health officials boil it down to two words: wear repellent.
