HARRISBURG, PA (WENY) - The keystone state is reporting its first human case of West Nile virus this year. Samples are being sent to the Centers for Disease Control and Prevention for confirmatory testing, but health officials are not strongly recommending that all residents minimize their exposure to mosquitoes.

The mosquitoes that transmit the West Nile virus are most active at dawn and dusk in areas with standing and stagnant water.

When outdoors, avoid bites by consistently using deet-containing insect repellents and covering exposed skin with lightweight clothing. To keep mosquitoes from entering your home, make sure window and door screens are in place and in good condition.

Keep in mid that about 80% of people who are infected will not show any symptoms.
