Mosquitoes are infected when they feed on birds or horses carrying the disease. The diseases cannot be spread by person-to-person contact.

Approximately 80 percent of those infected experience no symptoms, according to the federal Centers for Disease Control and Prevention. People older than 50 are most susceptible to infection, informs Newsandsentinel.

According to the Herald Net, dead birds infected with the virus are often found about two weeks before human cases are reported, Young said. West Nile virus primarily is a bird disease. Mosquitoes become infected by biting infected birds, then pass the virus to uninfected birds, humans and horses, according to the state Health Department. Crows, ravens and jays are tested for the virus because they are known to die from it.
