Campylobacter, the most commonly reported cause of bacterial enteritis in the U.S., is generally considered a foodborne pathogen associated with poultry. In rural agricultural areas, as found in parts of Georgia, environmental transmission associated with land use and other drivers may contribute to campylobacteriosis patterns. We analyzed trends in Campylobacter case rates in Georgia, with respect to demographics, geography, landuse, weather, and climate evaluating the importance of environmental drivers in transmission. Annual rates in Georgia have declined 68% from 1987-2003. Case rates were significantly greater for children <5, peaked in summer months, and were greatest in forest and wooded areas. Models were developed, using key weather and climate parameters, to explain the variability in case rates for key areas of the state. Results indicate a significant relationship between environmental variables and case rates in Georgia suggesting that transmission routes in rural areas may be related to factors other than food.
