The traps supplement the city's larvicide and mosquito spraying operations.

A Canyon County man has tested positive for the West Nile Virus, marking the first human case in the state this year, Southwest District Health officials said Thursday.

Weld County Health Department Executive Director Mark Wallace says the combination of wet and increasingly hot weather in the area has created the flawless conditions for the type of mosquito that carries West Nile Virus.

Maryland's Department of Agriculture said it found the virus in mosquitoes collected in the Riverdale Park area of Prince George's County.

To curb the ballooning threat of West Nile Virus, an aerial insecticide spraying has to be conducted. The previous high was in 2012, when they counted 1,363 virus-positive pools.

There are no medications to treat or vaccines to prevent infection.

"We are seeing a major expansion and build-up of West Nile virus in the mosquito population" said Dr. Philip Armstrong, medical entomologist at the station. "It is imperative that Pennsylvania residents take common-sense precautions to protect themselves from mosquitoes", said DEP Secretary Patrick McDonnell in a news release. Last year, there was one non-fatal human case. Our goal is for that to be the only one.

Keep in mind to use insect repellant when you go outdoors. The virus is spread through mosquitoes. Drain any standing water in your yard each week. "The small pool of water that collects in a single upturned bottle cap is an incubator for as many as 300 mosquito eggs", said Helwig. They say people should wear mosquito repellant that contains 10-35 percent DEET, wear light-colored clothing and stay inside during dusk.

Helwig and Carroll said the wet, hot weather is driving the increase in West Nile. For standing water that can not be drained such as fountains, ponds, etc., consider adding "Mosquito Dunks" or mosquito fish, which feed on mosquito larvae. These agencies are responsible for monitoring the potential public health threat of mosquito-borne diseases. The West Nile virus is a life-threatening disease that is contracted through an infected mosquito bite.
