Delta County Health Officer Bonnie Horn Koehler confirms two more cases of West Nile Virus in Delta County this year.
Koehler says that while both of the recent confirmed cases of WNV involved adults in their 50s, the virus is nondiscriminatory and has stricken people from infancy to 90-years old.
Health officials say that most people bitten by an infected mosquito show no signs or symptoms of illness. Some people however become ill 3 to 15 days after exposure. About one in five infected persons will experience mild illness with fever, and approximately one in 150-people exposed become severely ill. There is no treatment for WNV and Koehler stresses that prevention is key.
