A study published in Clinical Infectious Diseases examined the incidence of campylobacteriosis and Campylobacter outbreaks in the U.S. from 2004 to 2012.
Researchers studied laboratory-confirmed campylobacteriosis data from the Nationally Notifiable Disease Surveillance System, National Outbreak Reporting System, National Antimicrobial Resistance Monitoring System and Foodborne Diseases Active Surveillance Network. Campylobacteriosis causes foodborne illnesses.
Here are eight study findings:
1. From 2004 to 2012, 303,520 culture-confirmed campylobacteriosis cases were reported in the U.S.
2. The average annual incidence rate of Campylobacter infections was 11.4 cases per 100,000 persons.
3. The incidence rate among 4-year-old and up patients was more than double the overall incidence.
4. The incidence rate was highest among males in all age groups.
5. The incidence rate in Western states and rural counties were higher than southern states and metropolitan counties.
6. The annual incidence rate of Campylobacter infections increased 21 percent from 10.5 per 100,000 persons between 2004 and 2006 to 12.7 per 100,000 persons between 2010 and 2012.
7. The annual median number of Campylobacter outbreaks increased from 28 in 2004–06 to 56 in 2010–12.
8. In total, 347 were Campylobacter outbreaks reported.
