Which Georgia county has the largest mosquito control program?

• A. Chatham
• B. Fulton
• C. Cobb
• D. Gwinnett

Answer: (A)

The main idea here is understanding how “largest” is measured for mosquito control programs. In Georgia, a county’s program is considered largest when it has the widest scope in terms of population served, geographic area covered, and the amount of resources—staff, funding, and operations—dedicated to surveillance and control.

Chatham County stands out because it includes a large coastal population and diverse habitats that require extensive surveillance networks, frequent larval and adult mosquito control efforts, and substantial funding to sustain those activities. This combination leads to a more comprehensive, long-running program compared with the other large counties listed, which may have strong programs but on a smaller scale or with different organizational setups.
