Cryptosporidiosis in children in the Indian subcontinent

Area of Science:

• Public Health
• Infectious Diseases
• Pediatrics

Background:

• Cryptosporidiosis is a major cause of diarrheal illness in young children in developing nations.
• Sub-Saharan Africa and South Asia bear a high burden of cryptosporidial diarrhea.
• Undetected, asymptomatic cryptosporidial infections contribute to significant malnutrition in children.

Purpose of the Study:

• To review and analyze studies on cryptosporidiosis in children within the Indian subcontinent.
• To assess the prevalence and impact of cryptosporidiosis from 1983 to 2016.
• To identify knowledge gaps and methodological needs for future research.

Main Methods:

• A literature search was conducted for studies on childhood cryptosporidiosis in the Indian subcontinent (1983-2016).
• 54 out of 154 identified publications were included in the final analysis.
• Both hospital-based and community-based studies were analyzed, considering variations in detection methods.

Main Results:

• Hospital-based studies showed high variability in prevalence rates, indicating a need for standardized sampling and molecular detection tools.
• Community-based studies demonstrated consistent findings regarding prevalence, even across different locations and time periods.
• Using sensitive detection, cryptosporidial diarrhea represented 7%-9% of all diarrhea episodes, with 20%-30% of children experiencing at least one episode. Asymptomatic infections and multiple infections were common.

Conclusions:

• Cryptosporidiosis poses a substantial disease burden on children in the Indian subcontinent.
• There is a critical need for uniform methodologies and sensitive diagnostic tools in cryptosporidiosis research.
• Further research is required to address existing knowledge gaps concerning this parasitic infection.
