Sometimes infection can occur after contact with infected animals that do appear sick. Symptoms usually begin 4 to 7 days after exposure. Some people may also have a sore throat. You cannot tell without seeing your doctor. Your doctor may collect samples of stool, blood, or urine, and order tests to rule out other diseases.
Most people usually get better on their own.
Some people may have joint pain, usually in the knees, ankles or wrists. These pains can occur about one month after diarrhea starts and go away after 1 to 6 months. Some people, more commonly women, may have a skin rash that appears on the legs and trunk. This usually goes away on its own within a month. Blood infection may occur in people with weak immune systems or too much iron in their blood.
