A Mesa County resident has tested positive for West Nile virus (WNV). This is the first human case identified in Mesa County since 2015. The case follows an increase in Culex mosquitoes – the type of mosquito that carries WNV – in Mesa County.
“We work with the Grand River Mosquito Control District to monitor mosquito populations in our community. We’ve seen more Culex mosquitoes this year than in the past three years,” Epidemiology Program Manager Heidi Dragoo said.
“This human case of West Nile virus serves as a reminder to our community that although we were fortunate to see two years without any of the illness in humans, it’s still in Mesa County and can still affect our residents.”
According to Dragoo, working together to limit Culex mosquito populations and, of course, preventing mosquito bites remain the best ways to prevent West Nile virus in Mesa County.
Limit populations near your home and on your property.
Prevent mosquito bites.
Only one in five people infected with WNV show symptoms such as fever, headache, body ache and diarrhea. In some rare cases, WNV can cause more serious complications such as meningitis or encephalitis. Click here to learn more about West Nile virus.
