Many infections may be without symptoms. Symptoms usually start two to five days after infection. The range can be one to ten days. Poultry, especially chickens, turkeys and water fowl usually carry the organism. Most farm animals and meat sources can carry the organism.
People can spread the disease for several days to several weeks after they are infected.
The period of communicability can be shortened to a few days by providing treatment. After the diarrhea ends, persons may return, but they should be careful to wash their hands after using the toilet. No treatment is generally recommended. However, persons with diarrhea should drink plenty of liquids. Antibiotics may be used to treat persons with severe cases.
