Enterohemorrhagic Escherichia coli (EHEC) infection is a foodborne illness caused by a strain of the Escherichia coli bacterium, particularly associated with the E. coli O157:H7 serotype, which can lead to severe health issues. It is important for individuals showing symptoms of EHEC infection to seek medical attention promptly since the infection can cause serious health problems.
What Causes Enterohemorrhagic Escherichia coli Infection?
The causes of enterohemorrhagic Escherichia coli infection are generally related to the bacterium entering the body through food or water:
Undercooked or Raw Meat: Especially beef, is a common source of EHEC bacteria. Consuming undercooked or raw meat can lead to the transmission of the bacterium.
Unpasteurized Milk and Dairy Products: Unpasteurized milk and dairy products like cheese and yogurt made from such milk can be contaminated with EHEC.
Raw Vegetables and Fruits: Especially those consumed raw, such as cabbages, spinach, and lettuce, can come into contact with contaminated water or manure.
Drinking Water: Contaminated or insufficiently treated water can be a source of EHEC bacteria transmission.
Recreational Waters: Swimming or other water activities in natural water sources like swimming pools, lakes, and rivers can lead to infection through ingestion of contaminated water.
Person-to-Person Transmission: It is possible to transmit the infection through contact with an infected person, especially if hands are not washed after coming into contact with the feces of an infected person.
Contact with Animals: Farm animals, especially cattle, can be carriers of EHEC. Transmission can occur through direct contact with animals or contact with contaminated animal feces.
Kitchen Hygiene: Using kitchen utensils used for preparing raw meat without washing them before they come into contact with other foods can cause bacteria to spread to other foods.
Food Preparation and Storage: Storing raw and cooked foods in the same container or nearby can lead to the spread of bacteria.
Hand Washing: Insufficient hand washing habits, especially after using the toilet or before preparing food, increase the risk of spreading EHEC bacteria.
What Are the Symptoms of Enterohemorrhagic Escherichia coli Infection?
The symptoms of enterohemorrhagic Escherichia coli infection include:
- severe abdominal cramps
- bloody diarrhea
- nausea
- vomiting
- mild fever
- fatigue
- weakness
How Is Enterohemorrhagic Escherichia coli Infection Diagnosed?
Enterohemorrhagic Escherichia coli infection is diagnosed through the following methods:
- stool culture
- PCR tests
- ELISA tests
- serological tests
How Is Enterohemorrhagic Escherichia coli Infection Treated?
The treatment of enterohemorrhagic Escherichia coli infection generally focuses on alleviating symptoms and preventing complications:
Fluid and Electrolyte Balance: Ensure adequate fluid intake to prevent dehydration. Oral rehydration solutions can be used.
Rest: The patient should get plenty of rest.
Pain and Cramp Management: Pain relievers can be used if necessary to alleviate pain.
Antibiotic Use: Generally not recommended as antibiotics can worsen the condition by increasing toxin production by the bacteria.
Management of Hemolytic Uremic Syndrome (HUS): Hospitalization and intensive medical care are required if HUS develops.
Dialysis: Dialysis may be required in the case of kidney failure.
Blood Transfusions: Blood transfusions may be necessary in certain situations.
Avoiding Antidiarrheal Medications: Antidiarrheal medications are generally not recommended as they can prevent the elimination of toxins from the body.
How Should Enterohemorrhagic Escherichia coli Infection Be Managed?
The management of enterohemorrhagic Escherichia coli infection should be done carefully depending on the severity of the illness and the risk of complications:
Regular Monitoring: Patients’ symptoms should be regularly monitored and checked for any deterioration.
Attention to HUS Symptoms: Careful attention should be paid to symptoms of Hemolytic Uremic Syndrome (HUS) (decreased urine output, pale or yellowish skin, fatigue).
Hydration: Ensuring adequate fluid intake is very important for patients. Signs of dehydration should be monitored and intravenous fluid therapy should be administered if necessary.
Rest: Patients should be encouraged to get plenty of rest.
Pain Relievers: Appropriate pain relievers can be used for pain and cramps, but should be taken under a doctor’s advice.
Avoiding Antibiotics: Antibiotics are generally not recommended as they can increase toxin production by the bacteria.
Avoiding Antidiarrheal Medications: Antidiarrheal medications are not recommended as they can prevent the elimination of toxins from the body.
Hospitalization: Patients who develop HUS should be hospitalized.
Dialysis: Dialysis may be required in the case of kidney failure.
Blood Transfusions: Blood and platelet transfusions may be done if necessary.
Hand Washing: Hands should be washed frequently and correctly.
Isolation: Infected patients should be isolated to prevent the spread of the infection.
Food Safety: Food preparation and storage should be done under hygienic conditions.
Patient and Family Education: Patients and their families should be informed about the symptoms, management, and prevention of the infection.
Community Awareness: The community should be made aware of food safety and hygiene practices.
