What is Escherichia coli?
Escherichia coli is a type of bacteria commonly found in the intestines of humans and animals. There are many different types of E. coli. While some live harmlessly in the gut, others can cause a variety of illnesses, as these bacteria are present in feces and can survive in the environment.
What are the symptoms of E. coli infection?
Certain strains of E. coli can cause an array of illnesses, including:
- Gastroenteritis and food poisoning, both of which can lead to diarrhea, stomach pain, nausea, and vomiting. These symptoms usually last for less than 5 to 10 days.
- Urinary tract infections may cause pain or a burning sensation when urinating, frequent urges to urinate, or blood in the urine.
What causes E. coli infection?
E. coli infections can be contracted in several different ways, including:
- Contact with contaminated foods such as meat (especially poorly cooked ground beef in burgers), unpasteurized dairy products (such as raw milk) and fruit juices, and raw, unwashed fruits and vegetables.
- Contact with contaminated water, particularly in rural areas or swimming pools.
- Personal contact with sick individuals (especially from vomit or feces) or direct contact with animals carrying the bacteria.
What are the diagnostic methods?
The doctor takes a medical history and conducts a clinical examination, and may request additional procedures as needed, such as:
- Testing of stool, urine, blood, or any other relevant sample.
What are the treatment methods for E. coli?
Treatment involves various measures or as dictated by necessity, and may include the following:
Managing accompanying symptoms such as:
- Keeping the body hydrated by drinking plenty of fluids, like oral rehydration solution.
- Avoiding antiemetics or anti-diarrheal medications unless advised by a doctor.
Most people recover within 5 to 10 days without treatment, depending on the severity of the infection and its location.
What are the prevention methods for E. coli?
The risk of E. coli infection can be reduced by avoiding unsafe foods and practicing good hygiene, by:
- Always wash your hands after using the toilet or changing a baby’s diaper.
- Correctly preparing, cooking, and storing food in a safe manner.
- Not mixing raw foods with fresh foods, for example, from infected raw meat to fresh food.
- Washing fruits and vegetables in clean water reduces any E. coli contamination.
If a person is ill due to an E. coli infection, they can also take several steps to prevent infecting others by:
- Washing any soiled bedding, clothing, or household surfaces due to diarrhea or vomiting.
- Avoiding food preparation for others at home for 24 hours after symptoms disappear.
- Staying away from work or keeping children at home, away from childcare or school, for at least 24 hours after symptoms disappear.

What are the complications of E. coli infection?
Some strains of E. coli can cause serious diseases such as:
- Pneumonia.
- Meningitis in newborns.
- Cholecystitis.
E. coli can also cause a severe disease known as Hemolytic Uremic Syndrome, which destroys blood cells and can lead to kidney failure. Symptoms include:
- Dehydration.
- Decreased urination.
- Lethargy.
- Pale skin (due to anemia).
- Yellowing of the skin and eyes (due to jaundice).
- Swelling from fluid retention.
- Seizures.
Elderly people, young children, and individuals with weakened immune systems are most at risk of serious illness.
When should you see a doctor?
Consult a doctor if you have:
- Severe or bloody diarrhea.
- High fever with diarrhea.
- Symptoms of Hemolytic Uremic Syndrome.
- Dehydration.
- Severe abdominal or rectal pain.
- Signs of a urinary tract infection.
- Concerns about the potential for pneumonia.
And diarrhea lasts more than two days in an adult, or more than 24 hours in an infant.
