A mosquito in Chatham County has tested positive for West Nile virus.
It's the first case there in four years, and no humans have tested positive.
The Chatham County Mosquito Control has been spraying for mosquitoes all summer.
Henry Lewandowski with the Chatham County Mosquito Control says it works:
“In 2007, we had 36 positive samples throughout that season, and did not have any human disease locally, so we have the resources to prevent a major epidemic, we believe.”
The drought conditions in Savannah have created the perfect conditions for mosquito breeding. Lack of rainfall prevents the mosquito nests from being washed away.
This year, a few cases of West Nile have appeared in metro Atlanta. Health officials are going door-to-door in those neighborhoods to remind people to take precaution against mosquito bites.
