Spraying for Mosquitos
West Nile Mosquito Outbreak
No one really knows why there has been such a large outbreak of WNV this year. Decoded Science asked Nordlund what the CDC’s thoughts were on the increase of this virus, and she responded: “It is not clear why there is more West Nile virus activity this year than in recent years. Although we do know that many factors could be contributing to the increase. The weather, numbers of birds that maintain the virus, numbers of mosquitoes that spread the virus, and human behavior are all factors that can influence when and where outbreaks occur. The unusually mild winter, early spring, and hot summer in many parts of the country might have fostered conditions favorable to breeding the mosquitoes that spread West Nile virus to people. CDC has two teams of scientists in Texas assisting the Texas State Department of Health with figuring out why there is such a large outbreak there.”
The CDC and local health departments continue to work at decreasing the mosquito population and preventing disease. By taking action around your own home, you can help keep the West Nile virus away from your family as well.
