AMES, Iowa – Recent testing from Iowa State University (ISU) and the State Hygienic Lab indicate that mosquitoes from traps in Ames, Iowa have tested positive for the West Nile Virus. While there is a lag time between collecting the samples and the testing, the results suggest mosquitoes with the potential to carry West Nile Virus are likely still present. "At this point in the summer, it is not unusual to see positive West Nile Virus tests. The information is helpful because we can implement preventative measures such as spraying, larvicide, and removal of standing water to reduce mosquito populations. We also use these results to remind people to take precaution when they are outdoors," said Dr. Ryan C. Smith, ISU Department of Plant Pathology, Entomology and Microbiology. Mosquitoes thrive in the warm, wet weather of summer. Even without significant rainfall, mosquitoes can still become a concern. There are several ways to avoid and get rid of mosquitoes. "The most effective way to eliminate mosquitoes is to remove standing water in residential areas where even a small amount of standing water from flower pots, buckets, or barrels can be enough for a mosquito to lay eggs," Smith said. "When spending time outside, it's important to take precautions to prevent bites. Wearing mosquito repellent or long-sleeved shirts and long pants can be used as preventive measures, especially at dusk and dawn when mosquitoes that transmit West Nile Virus are most active." According to the Centers for Disease Control, most people infected with the virus see no symptoms. However, one in five people infected will develop flu-like symptoms such as fever, headache, body aches and rash. At worst, about one in 150 people infected will develop a severe, sometimes fatal illness. There are currently no vaccines to prevent or medicines to treat the virus. Stay ahead of the curve!
