Yuma County Health Department trains for mosquito season this summer

YUMA, Ariz. (KYMA, KECY) – With rising temperatures this summer, the Yuma County Health Department says there's an increased risk of mosquitoes carrying diseases.

All this week, the Yuma County Health Department has been conducting CDC Biobottle Assay training to measure chemical resistance to insecticides in local mosquitoes like those here.

“Mosquitoes can spread disease, so what we want to do is make sure that the chemicals we're using to control the mosquitoes are actually working and killing the mosquitoes,” said Richard Cumming III, vector control program supervisor for the Yuma Health Department.

According to the Centers for Disease Control, mosquitoes are more prevalent in the summer because warmer temperatures heat stagnant water, providing breeding grounds for mosquitoes.

According to the health department, several mosquito swarms along the Colorado River tested positive for West Nile virus and St. Louis encephalitis in May and June, but there have been no known human cases in Yuma and no known cases in Imperial County.

They say the study is important to provide hard data for mosquito control districts. The health department says it plans to follow up with a second training session later this year.
