An additional human case of West Nile Virus has been confirmed in the Coachella Valley, bringing the total number of cases to four in the valley this year, and a total of 14 for all of Riverside County.
The Coachella Valley Mosquito and Vector Control District received confirmation of the case - a Palm Desert resident - from the Riverside County Department of Public Health.
"It is critical for Coachella Valley residents to understand that we are still seeing West Nile Virus activity even as the weather cools off," said Jeremy Wittie, M.S., the Scientific Operations Manager at the Control District. "People need to ensure they are using repellant and are covered in the early morning and early evening, as we continue our control efforts to protect communities."
In response to this latest case, the Control District will conduct ultra-low volume applications to catch basins and storm drain systems in Palm Desert with handheld ULV machines; redirect personnel from other zones to Palm Desert to perform enhanced mosquito larval surveillance; increase inspection and treatment of mapped sites in the city, including re-checking all green pools; actively seek breeding sources which may exist; and perform barrier applications to vegetation, such as hedge rows and street side landscaping.
West Nile virus is transmitted to humans and animals by the bite of an infected mosquito. People 50 years of age and older have a higher chance of getting sick and are more likely to develop complications.
There have been 364 confirmed human cases of West Nile Virus in California this year, according to the California Department of Public Health run website and a total of 4,891 cases in the United States, according the Centers for Disease Control and Prevention website.
This year in the Coachella Valley there have been four confirmed human cases, compared to one in 2011.
