Enteric Fever
1. Definition
Enteric fever is a bacterial infection caused by Salmonella Typhi and Salmonella Paratyphi, which affects the gastrointestinal tract. It is characterized by high fever, abdominal pain, and diarrhea. Additional context: Enteric fever is also known as typhoid fever.
2. Synonyms
- Typhoid fever
- Paratyphoid fever
- Enteric fever
3. Causes / Etiology
- Salmonella Typhi: This bacterium is the primary cause of enteric fever. It is transmitted through contaminated food and water, as well as through close contact with an infected person.
- Salmonella Paratyphi: This bacterium causes paratyphoid fever, which is similar to typhoid fever but has a milder course.
- Contaminated food and water: Food and water contaminated with Salmonella Typhi or Salmonella Paratyphi can cause enteric fever.
- Close contact with an infected person: Close contact with an infected person, such as through touching or sharing utensils, can also transmit the bacteria.
4. Types / Classification
- Typhoid fever: Caused by Salmonella Typhi, it is characterized by high fever, abdominal pain, and diarrhea.
- Paratyphoid fever: Caused by Salmonella Paratyphi, it is similar to typhoid fever but has a milder course.
- Typhoid carriers: Some people can become carriers of Salmonella Typhi, carrying the bacteria in their gallbladder without showing symptoms.
5. Pathophysiology / Pathology
- Invasion: Salmonella Typhi enters the body through the gastrointestinal tract.
- Colonization: The bacteria multiply in the intestinal tract, causing inflammation and damage to the intestinal lining.
- Systemic infection: The bacteria enter the bloodstream, causing a systemic infection that affects multiple organs.
- Fever and inflammation: The body's immune response causes fever, inflammation, and damage to various organs.
6. Clinical Features
- Acute typhoid fever:
- High fever (up to 104Β°F)
- Abdominal pain and tenderness
- Diarrhea or constipation
- Headache and fatigue
- Chronic typhoid fever:
- Prolonged fever and illness
- Weight loss and fatigue
- Abdominal pain and tenderness
7. Complications
- Acute complications:
- Intestinal perforation
- Sepsis
- Meningitis
- Chronic complications:
- Chronic carrier state
- Intestinal obstruction
8. Investigations / Diagnosis
- Routine tests: Complete blood count (CBC), blood culture, and urine culture.
- Specific tests: Salmonella Typhi or Salmonella Paratyphi antigen detection in stool or urine.
- Confirmatory tests: Salmonella Typhi or Salmonella Paratyphi isolation from stool or blood culture.
9. Differential Diagnosis
- Malaria: Similar symptoms, but with a different epidemiology and treatment.
- Urinary tract infection: Similar symptoms, but with a different epidemiology and treatment.
- Gastroenteritis: Similar symptoms, but with a different epidemiology and treatment.
- Rickettsial infections: Similar symptoms, but with a different epidemiology and treatment.
10. Management / Treatment
- General management: Rest, hydration, and nutrition.
- Modern medicine treatment:
- Antibiotics (e.g., ciprofloxacin, ampicillin)
- Supportive care (e.g., fluids, electrolytes)
- Diet and lifestyle advice:
- Avoid contaminated food and water
- Practice good hygiene (e.g., handwashing)
- Get plenty of rest and nutrition
