LAS VEGAS (AP) — Nevada health officials are urging residents to protect themselves from bug bites after mosquitoes in two ponds in Clark County and another in Lyon County tested positive for West Nile Virus.
Officials say the ponds in Mason Valley in northern Nevada, and Logandale is southernNevada, could signal the virus is in other areas of the state this summer.
West Nile virus is spread through the bite of infected mosquitoes but is not spread person to person. Symptoms include fever, headache, vomiting and sometimes swollen lymph glands or a skin rash on the chest, stomach and back.
The disease can sometimes be fatal.
Health officials recommend using bug repellants and avoiding standing pools of water where mosquitoes breed.
Clark County reported no human cases of West Nile Virus last year.
