West Nile virus cases tend to peak in August for North Dakota, but it is possible to occur at any time, said Michelle Feist, epidemiologist with the North Dakota Department of Health, Division of Disease Control. A previous positive mosquito sample was collected from this same trap on June 22.
On July 19, the City of Fort Collins reported a pool of mosquitos had tested positive for the virus, making it the second case in Larimer County.
West Nile virus is a potentially serious illness that is usually spread to animals and humans through the bite of an infected mosquito.
"West Nile is always a concern in the late summer, early fall here in North Dakota", Iszler said. The annoying bugs carry Zika, West Nile Virus, dog heartworm and other disease. Humans who become infected with the virus typically don't show symptoms, but the very young, very old and people with certain medical conditions that affect their immune response can be at higher risk of getting sick.
Colorado saw a total of 149 human cases of the virus past year, eight of which were fatal.
Justin Smith, environmental health director for the Kent Health Department said the city sprayed in the areas where the infected mosquitoes were discovered.
Eight Vermonters have contracted West Nile since 2011. In 2016, the State tested 3,243 mosquito pools, of which 19 were positive for West Nile virus.
Use insect repellant containing DEET, Picaridin, or Oil of Lemon Eucalyptus. "These areas are not located inside mosquito abatement districts".
The Vanderburgh County Health Department will continue to focus its efforts on habitat elimination, education, and treatment of stagnant or standing water as these are the most effective forms of mosquito control. Precautions include draining any standing water on your property and wearing repellent when outdoors.
