Scrub typhus: audit of an outbreak

Area of Science:

• Pediatric Infectious Diseases
• Epidemiology of Tropical Diseases
• Clinical Microbiology

Background:

• Scrub typhus is a significant cause of febrile illness in children in endemic regions.
• Early diagnosis and treatment are crucial to prevent severe complications.

Purpose of the Study:

• To delineate the epidemiological, clinical, and laboratory features of pediatric scrub typhus.
• To identify key diagnostic markers and assess treatment outcomes in children.

Main Methods:

• Retrospective analysis of case records of children diagnosed with scrub typhus.
• Data collection included presenting symptoms, physical findings, laboratory parameters, and complications.

Main Results:

• Fever was universal; leg swelling and vomiting were common. Eschar (67%), hepatomegaly (94%), and splenomegaly (73%) were frequent findings.
• Laboratory results showed elevated C-reactive protein (CRP) (92%), hypoalbuminemia (79%), and leukocytosis (56%).
• Acute kidney injury (10%) and peripheral gangrene (4%) were noted complications, with no mortality.

Conclusions:

• The study highlights the characteristic clinical and laboratory profile of scrub typhus in children.
• Presence of eschar, hepatosplenomegaly, and elevated CRP are valuable diagnostic clues.
• Children showed good response to treatment, emphasizing the importance of timely intervention.
