Commissioners in Savannah's Chatham County approved nearly three-hundred-thousand dollars to buy more mosquito-fighting pesticides.

The county is fighting its worst season for West Nile virus in years and was about to run out of money for pesticides it sprays over the community using a helicopter.

Mosquito control director Henry Lewandowski says, the additional funding will keep the aerial fight against mosquitoes going for another month.

"Officially, our health department has recorded six cases of human disease," Lewandowski says. "And we've responded in kind and since the beggining of July have been treating various parts of the community seven nights a week."

Health officials say, more than 200 mosquitoes have tested positive for West Nile this year, the most since 2007.

The county's total annual budget for mosquito control is more than $3 million.
