E. coli is the name of a germ, or bacterium, that can live in your stomach and intestines. Some types of E. coli can cause illness and symptoms, such as bloody diarrhea and cramps.
Symptoms of E. coli infection usually end in about 1 week with no further problems. But some people have severe blood and kidney problems.
People in the United States most often get an E. coli infection from eating meat that has been contaminated with E. coli. You can also get the infection from eating raw fruits and vegetables or dairy products that are contaminated with the bacteria. And you can get it from others who are infected.
E. coli is a type of bacteria that lives in the digestive tracts of humans and animals. There are many types of E. coli, and most of them are harmless. But some can cause a dangerous type of diarrhea.
Children are more likely than adults to have symptoms of an E. coli infection. Most people with the infection will have:
Some people don't notice any symptoms. They may spread the bacteria to others without knowing it.
Symptoms usually start 1 to 4 days after coming in contact with E. coli.
Most people get better in about a week. They often don't see a doctor and don't know that E. coli caused their problems.
With some strains of E. coli, severe blood and kidney problems may occur within 2 weeks after the diarrhea starts. These problems can cause kidney failure and sometimes long-term disability or death in some children and older adults.
When E. coli causes serious problems with the blood or kidneys, symptoms include:
An E. coli infection usually goes away on its own. Your main treatment is to make yourself comfortable and drink sips of water to help prevent dehydration. In some people, the infection causes serious problems with the blood and kidneys. These people may need blood transfusions or dialysis.
