The symptoms may begin hours to days after you become infected. Symptoms may include:
Diarrhea - acute and severe
Loss of appetite
Signs and tests
A stool culture may be done to determine the type of infection. However, this test may not always identify the bacteria causing the illness.
Mild cases usually do not need treatment.
Antidiarrheal medication may not be recommended because it can slow the germ from leaving the digestive tract.
Rehydration with electrolyte solutions may be needed if the body does not have enough fluids (dehydration).
Persons with diarrhea (especially young children) who are unable to drink fluids because of nausea may need medical care and fluids through a vein (intravenous fluids).
If you take diuretics and develop diarrhea, you may need to stop taking the diuretic. However, do not stop taking any medicine unless directed by your health care provider.
Symptoms usually go away without treatment in a few days.
Note: The diarrhea can cause rapid and extreme dehydration in babies.
Calling your health care provider
Call for an appointment with your health care provider if:
Diarrhea does not go away in 3 to 4 days
You have a fever over 101 degrees Fahrenheit
There is blood in the stools
