West Nile virus can be spread by mosquito bites and is not transmitted among humans. Mosquito season typically runs April to November.
West Nile virus has made a regular appearance in the county since 2002. Over a five-year period, six cases were reported, according to the release.
Mosquitoes breed in standing water, health officials said. Residents can protect themselves by eliminating such water and taking other precautions such as cutting shrubs and hedges where the bugs shelter. Complaints about properties with stagnant water can be directed to the health department at 412-350-4046.
