4 Campylobacteriosis
4.1 Epidemiologic Review
4.1.1 Disease Information
Overview: Campylobacteriosis is an infectious disease caused by the Campylobacter bacteria. It is one of the most common causes of diarrheal illness in the United States.
Symptoms: Symptoms typically include diarrhea (sometimes bloody), fever, abdominal cramps, and nausea. Symptoms usually occur within 2-5 days after exposure and last about a week.
Transmission: Transmission can occur through the ingestion of contaminated food, milk (unpasteurized), or water. It can also be transmitted from person-to-person through the fecal-oral route.
Treatment: Most people recover without treatment and antibiotics are only recommended for the very ill.
Prevention Proper hand hygiene after contact with animals and before eating will help prevent the spread of disease, as well as only drinking pasteurized milk.
