Enteric fever in young Yoruba children

Area of Science:

• Pediatrics
• Infectious Diseases
• Tropical Medicine

Background:

• Typhoid and paratyphoid fever are significant public health concerns in endemic areas.
• Differentiating enteric fevers from other febrile illnesses like malaria is challenging in resource-limited settings.

Purpose of the Study:

• To describe the clinical presentation, differential diagnoses, and outcomes of typhoid and paratyphoid fever in Nigerian children under 5 years.
• To highlight the challenges in diagnosing and managing these infections in a holoendemic malarial region.

Main Methods:

• A study of 97 Nigerian children under 5 years with blood culture-confirmed typhoid or paratyphoid fever.
• Clinical data including symptoms, differential diagnoses (especially malaria), and treatment responses were analyzed.

Main Results:

• Typhoid and paratyphoid fever presented with indistinguishable symptoms including fever, anemia, and gastrointestinal or neurological disturbances.
• Malaria was a key differential diagnosis and potentially contributed to anemia.
• Despite intensive therapy (chloramphenicol/trimethoprim, transfusions), mortality for both typhoid and paratyphoid was high at 18%.

Conclusions:

• Enteric fevers pose a severe threat to young children in this malarial endemic area, with high mortality.
• Clinical presentation alone is insufficient for diagnosis, necessitating laboratory confirmation.
• Effective prevention and treatment strategies are crucial to reduce the burden of these diseases.
