Symptoms
The symptoms of E. coli infection can vary depending on the strain of bacteria involved. Common symptoms in children include:
- Diarrhea, which may be bloody
- Stomach cramps and pain
- Nausea and vomiting
- Fatigue and weakness
- Low-grade fever
- Loss of appetite
In some cases, children may also experience skin rashes or joint pain. In severe cases, E. coli can lead to kidney failure and anemia. Symptoms usually appear within 2 to 5 days after exposure to the bacteria.
Causes
E. coli infections are typically caused by consuming food or water that is contaminated with the bacteria. Some common sources of E. coli include:
- Undercooked ground beef
- Unpasteurized milk or juice
- Contaminated water, such as from lakes or swimming pools
- Fruits and vegetables that have been contaminated with feces
- contact with infected animals, such as at petting zoos
Children are at a higher risk of infection if they have weakened immune systems or if they are in close contact with infected individuals.
