A little more than a month after the first birds started testing positive for West Nile virus, mosquitoes are now testing positive too.
Mosquitoes in Peru tested positive for the virus on Friday. The house mosquito is the main way the disease can be transmitted, and this is the first positive mosquito test this year.
West Nile virus, if caught by humans, can lead to nausea, a fever, headache and muscle aches. Severe complications have been reported in rare instances. The county health department has diagnosed one case in the county in 2016.
People older than 50 and those with weakened immune systems are at a higher risk of severe illness from West Nile virus.
