Community-acquired bacteraemia in African children

Area of Science:

• Pediatrics
• Infectious Diseases
• Microbiology

Background:

• Community-acquired bacteraemia is a significant cause of febrile illness in children globally.
• Understanding the aetiology of bacteraemia is crucial for effective treatment and public health strategies in resource-limited settings.

Purpose of the Study:

• To determine the frequency and causative agents of community-acquired bacteraemia in febrile children in Kigali, Rwanda.
• To compare clinical characteristics and outcomes of bacteraemic children with non-bacteraemic controls.

Main Methods:

• Prospective study involving 900 consecutive febrile children (temperature >= 39°C) attending an outpatient clinic.
• Blood cultures were performed, and pathogens were identified.
• Comparison with febrile, non-bacteraemic children with or without Plasmodium falciparum parasitaemia.

Main Results:

• A pathogen was isolated from 112 children (12.4%), with Salmonella species accounting for 74% of isolates.
• Salmonella typhi was the most common pathogen, particularly in older children.
• Bacteraemic children had higher admission rates and presented more frequently with gastrointestinal symptoms.

Conclusions:

• Community-acquired bacteraemia is prevalent in Rwandan children and predominantly caused by Salmonella species.
• Prompt diagnosis and appropriate management are essential for improving outcomes.
• Further research into Salmonella epidemiology and control is warranted.
