Leptospirosis: a childhood disease.

Area of Science:

• Pediatric infectious diseases
• Zoonotic disease epidemiology
• Clinical microbiology

Background:

• Leptospirosis is a significant zoonotic disease with diverse clinical presentations.
• Understanding transmission routes and serotype prevalence is crucial for public health.
• Pediatric cases require specific diagnostic and management considerations.

Observation:

• Nine pediatric leptospirosis cases were identified at St. Louis Children's Hospital over 54 months.
• Urban settings and contact with dogs were identified as primary risk factors.
• Serotypes beyond L. icterohaemorrhagiae were associated with severe illness.

Findings:

• The study highlights a high incidence of urban leptospirosis cases in children.
• Dog exposure was the most probable source of infection.
• Severe clinical manifestations, including acalculous cholecystitis and pancreatitis, were observed.

Implications:

• This research underscores the importance of considering leptospirosis in urban pediatric populations.
• It emphasizes the need for broader diagnostic awareness beyond common serotypes.
• Identifying unusual presentations aids in earlier diagnosis and treatment of severe pediatric leptospirosis.
