More mosquitoes lead to rise in West Nile cases in Maricopa County

West Nile Virus is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird.

There have been no cases so far of West Nile or Eastern Equine Encephalitis - which are considered more risky; however those tend to appear more towards August and September. Most people with the virus are asymptomatic or experience mild, flu-like symptoms. More severe ones can include tremors, drowsiness, confusion, swallowing problems, high fever and unconsciousness.

Folks older than 50 or with weakened immune techniques are extra weak to the virus and extra prone to undergo mind and spinal twine infections if contaminated. When scientists plugged their findings into a model created to simulate the risk of disease outbreaks, researchers found light pollution increased the potential for a West Nile virus outbreak by 41 percent.


"The third measure is avoiding going outside during dawn or dusk, when mosquitoes are most active", Maruti said.

Kernbach says they picked the little brown birds since they live in close proximity to humans in urban areas, play host to a number of parasites and diseases, and are frequent carriers of WNV.

If the monitoring traps show persistent West Nile, however, the city will spray pesticide to kill adult mosquitoes in targeted areas.


Make sure windows have screens.

Eliminate any standing water from your property and dispose of containers that can collect water. Fix or replace screens with tears or holes. Drill holes in tire swings so water drains out. Keep them empty or covered if not in use.
