West Nile virus detected in Garfield County mosquitoes

West Nile virus has been detected in mosquitoes in Battlement Mesa. The detection is part of a county effort to control the population of mosquitoes that carry viruses. Each summer, Garfield County Public Health traps and tests adult mosquitoes. In identified risk areas, mosquito larvae are treated to reduce mosquito populations. West Nile virus is transmitted to people through mosquito bites. Because West Nile can be a serious illness, it is important to take precautions. “West Nile is spread when mosquitoes feed on infected birds and then feed on humans,” said Garfield County Public Health Director Joshua Williams. “These mosquitoes

Mosquitoes are an annual annoyance and no one loves getting bit. In Colorado, some mosquitoes carry the West Nile virus, a rare but serious illness. The virus circulates in sick birds in late June to early September. It is transmitted to people when Culex tarsalis mosquitos bite an infected bird and then bite a person. Areas around the Colorado River Valley have had higher numbers of Culex mosquitos. Garfield County reports weekly trapping and testing results to assess mosquito risk. Most people show no symptoms, but in rare cases, the virus can cause serious brain infections. There is no vaccine

A man adds wood into his woodstove inside his home.

Changing out one old wood stove with a newer, cleaner wood burning stove reduces emissions by an average of 70 percent. That is equivalent to removing seven old diesel buses off the road.
