West Nile mitigation keeps Yuma County, Cocopah reservation free of virus
October 27, 2021
With Arizona's healthy monsoon and an explosion of mosquito-borne West Nile virus cases, Yuma County has partnered with the Cocopah Indian Tribe south of Yuma to create an effective shield against the disease.
For the first time, Yuma County's Pest Abatement District provided training and supplies to the reservation for mosquito surveillance and mitigation. That allowed the tribe the flexibility to react to rising cases in real time and use a variety of methods to prevent infections.
Their timing turned out to be fortunate. So far, the county has had zero cases in a year when parts of the state are seeing record infections, thanks to ample summer storms. Maricopa County alone has reported 182 cases as of mid-October, compared with just a few last year. Deaths statewide so far have reached 24, according to the Arizona Department of Health Services.
