There are certain types of E. coli that are infectious and can instigate an illness known as E. coli enteritis if an individual has eaten food or drank water contaminated by the bacteria. The symptoms of E. coli usually manifest within 24-72 hours after exposure and can last up to seven days.

One of the most common indications linked with an E. coli infection is no other than diarrhea. It is a medical condition characterized by the frequent urge to produce bowel movement which usually involves watery or loose stools. If an individual has E. coli infection, the individual can experience severe and abrupt diarrhea and even blood in the stools.

Diarrhea can even disrupt the ability of the body to absorb fluid from food in the digestive tract, resulting to the development of diarrhea. The dehydration can also trigger additional symptoms such as increased thirst, headache, fatigue, lightheadedness and even loss of consciousness. If an individual is infected with E. coli, it is vital that the individual stays hydrated in order to prevent further medical complications.

An individual who has been exposed to E. coli can suffer from fever. This is considered as a normal immune response initiated by the body in an attempt to prevent bacteria or viruses from replicating and spreading all over the body. The fever linked with E. coli infection is usually low grade which is less than 101 degrees F and steadily subsides as the infection resolves. If the individual develops high fever, it is important to consult a doctor right away for proper evaluation and care.


If the individual consumes water or food that has been contaminated by E. coli, the individual can suffer from vomiting as a symptom of the condition. Once the pathogens enter the digestive tract, the body can trigger vomiting in an attempt to eliminate infectious pathogens from invading the body. The vomiting linked with E. coli infection can be severe and can even cause dehydration to develop in some individuals.
