Campylobacteriosis is a bacterial diarrheal disease usually transmitted through raw or undercooked foods of animal origin or foods cross-contaminated by animal food products or feces. It can also be transmitted by untreated or contaminated water or through person-to-person transmission via the fecal-oral route. In Indiana, the following risk factors are the most common: contact with pets (most commonly dogs and cats), chicken consumption within five days prior to illness, contact with someone with similar symptoms, travel outside of Indiana, contact with untreated water, and contact with livestock.

In 2005, there were 473 cases of campylobacteriosis reported in Indiana, indicating a rate of 7.54 cases per 100,000 population (Table 1). This represents a slight increase in reported cases compared to 2004 (445). Figure 1 shows reported cases by year for 2001-2005. Incidence of disease was greatest during the summer months. Figure 2 shows cases per month for 2005. As shown in Figure 3, age-specific rates were greatest for preschoolers aged 1-4 years (13.07), followed by infants under the age of 1 year (10.45), and adults aged 70-79 years (10.23). Males (8.45) were more likely to be reported than females (6.56). The rate for whites (5.49) was higher than that for other races (4.29) or blacks (2.16); however, 149 cases (31.5%) did not report race data.

The incidence rates were highest among the following counties reporting five or more cases: Franklin (30.3), Randolph (26.2), and Tippecanoe (21.4). Figure 4 shows counties reporting five or more cases of campylobacteriosis in 2005. There were no outbreaks of campylobacteriosis reported in Indiana in 2005.
