Campylobacteriosis is an infection caused by a bacteria that affects the intestinal tract. You can get it by eating food or drinking water that is contaminated with the campylobacter bacteria. Anyone can get a campylobacter infection and you can get it more than once. Campylobacter is one of the most common bacterial causes of diarrheal illness in San Francisco. Practically all cases occur as single cases, not as part of an outbreak.
What are the symptoms of campylobacteriosis?
A campylobacter infection may cause mild or severe diarrhea, often with fever, stomach cramps or traces of blood in the stool. Campylobacteriosis can also cause nausea and vomiting. Some people have no symptoms at all. The illness usually lasts a week. For people who have a weakened immune system, the illness can last longer and be more serious.
How is campylobacter spread?
Campylobacter bacteria are usually spread by eating or drinking contaminated food or water. Eating food that has been contaminated with juices from raw chicken is the most common source of this infection. Raw chicken and meat are frequently contaminated with campylobacter. Many animals, including chickens, pigs, cows, dogs and birds may carry the germ without being sick. This infection is also common in the developing world so travelers to some foreign countries are also at risk.
How soon after becoming infected do symptoms appear?
Symptoms generally appear 2 to 5 days after being infected with campylobacter, but can range from 1 to 10 days after eating the contaminated food or water.
For how long can a person carry the campylobacter germ?
Generally infected people will continue to pass the bacteria (germ) in their stool for several days to several weeks. Certain medicines may shorten the time you are infected.
Do infected people need to be isolated or excluded from school or work?
Since these germs are carried in the stool, the stools of people with active diarrhea should be considered infectious. Infected people should wash their hands with soap and warm water each time after using the toilet. Infected food handlers, child care workers and health care workers may return to work when their diarrhea stops, provided that they carefully wash their hands after every toilet visit. People who change diapers of infants should thoroughly wash their hands after each diaper change.
What is the treatment for a campylobacter infection?
Most people infected with campylobacter get well on their own. Drinking plenty of fluids when sick will help prevent dehydration. Antibiotics are sometimes given by your doctor to treat severe illness and may shorten the length of time you are sick if given early in the illness.
