In 1985 campylobacteriosis became a reportable condition in Texas. Figure 1 demonstrates the incidence rate over the past 10 years for Texas. In 1998 there were 881 cases of reported campylobacteriosis, for an incidence rate of 4.5 cases per 100,000 population. In 1998 46% (404 cases) of the Campylobacter isolates were speciated. Campylobacter jejuni accounted for 93.6% of the speciated cases.

As is commonly seen with other fecal-oral transmitted illnesses, children under the age of 5 years composed the largest percentage (27.4%) of reported cases (241), for an incidence rate of 15.0 cases per 100,000 population. The second highest percentage (14.2%) of reported cases occurred among the 20-29-year-old age group, however the incidence rate for this group was only 4.3 cases per 100,000 population. Percentage of reported campylobacteriosis cases by age group are shown in Figure 3.
