Recent testing shows mosquitoes from a trap in an Ames park tested positive for West Nile virus. The city says the insects were found in Emma McCarthy Lee Park, and the virus confirmed by Iowa State University. ISU entomologist Ryan Smith says we're moving into the peak season of West Nile transmission, so preventative measures like spraying, larvicide, and the removal of standing water can reduce mosquito populations. The Centers for Disease Control says 80-percent of people infected with West Nile will have no symptoms. One-in-five will develop flu-like symptoms like fever, headache, body aches, and a rash. most will recover completely, but may experience weeks of fatigue. About one in 150 people infected will develop a severe illness.
