The mosquitoes that transport the western Nile virus have reached one of the highest numbers ever registered in Minnesota during the month of July, and the authorities warn citizens to stay inside at dusk and at dawn.
Insects that suck blood in the seven counties of the Minneapolis Paul Metropolitan Area, gave positive for the disease, according to the Metropolitan District of Mosquito Control (MMCD).
MMCD environmentalists processed almost 200 mosquito swimming pools and found the mosquitoes of Culex Tarsalis, the species most blamed for propagating the western Nile virus, were “active in some of the highest numbers” ever registered, according to News 9 Minneapolis-ST. Pablo.
The western Nile virus is mainly transmitted by several species of Culex, including Culex Salinarius and Culex Pipiens, health officials say. (Istock)
