According to the health district, the virus is most commonly spread by mosquitoes.

“Mosquitoes become infected when they feed on infected birds. Infected mosquitoes can then spread the virus to humans and other animals they bite,” health district officials said in the release.

Health officials said about 80 percent of people infected with the virus will not show any symptoms at all. Most who will show symptoms show them between three and 14 days of being bitten by a mosquito.
