Animals and humans

Fecal-oral, ingestion of contaminated food or water, and the eating of raw meat

Does not commonly cause death, it has been estimated that approximately 124 persons with Campylobacter infections die each year.

Case Fatality Ratio
Case Fatality Ratio Pathway/conditions Population References
0.19% (95% CI: 0.13-0.27%) Infected domestically (in Sweden)

Within first month following illness

Sweden [1]
0.008 (95% CI: 0.0008-0.03%) Infected Abroad (outside of Sweden)

Within first month following illness

Not Reported [1]
0.23% foodborne infection Denmark [2]

3-5 days or up to a week [3]

It is estimated to affect over 2.4 million persons every year, or 0.8% of the population. [4]
In 2010, the CDC reported an incidence 13.6 per 100,000 for Campylobacteriosis. [5]

Duration of infectiousness and disease

Symptoms typically reside in one week. Antibiotic treatment has been shown to decrease the duration of intestinal symptoms by 1.32 Days (95% CI: 0.64-1.99) However, because of drug resistance problems, antibiotics are only advised in complicated cases.[6]


Illness can cause symptoms beginning 2-5 days after exposures. These symptoms include abdominal pain, cramping, diarrhea, and fever.

Post-infectious complications include...

  • Reactive Arthritis (7%)
  • Guillain-Barre syndrome (1-3/10,000)
  • Bacteremia (<1%)

Excretion Rates (see Exposure)


Gram-negative, spiral, and microaerophilic. Motile, with either unipolar or bipolar flagella, the organisms have a characteristic spiral/corkscrew appearance and are oxidase-positive
