Snake bite in South Asia: a review

Area of Science:

• Public Health
• Tropical Medicine
• Toxicology

Background:

• Snake bite envenoming is a critical yet neglected global health issue, particularly in tropical, rural communities.
• South Asia faces the highest burden due to population density, agricultural practices, diverse venomous species, and inadequate control programs.
• Despite advances in venom research and antivenom production, snake bite management in South Asia remains suboptimal.

Purpose of the Study:

• To highlight the significant public health challenges posed by snake bite envenoming in South Asia.
• To identify the multifaceted deficiencies in current snake bite management strategies in the region.
• To emphasize the need for collaborative, evidence-based interventions to improve outcomes.

Main Methods:

• Review of existing literature on snake bite epidemiology, clinical features, and management in South Asia.
• Analysis of factors contributing to the ineffectiveness of current snake bite control programs.
• Identification of gaps in diagnostics, antivenom availability, and healthcare delivery.

Main Results:

• Accurate global snake bite burden is unknown due to underreporting.
• Existing antivenoms do not cover all regionally significant venomous snakes.
• Inappropriate first-aid and delayed transport to treatment centers are common, exacerbated by treatment costs.

Conclusions:

• Snake bite management in South Asia is hampered by a lack of species-specific diagnostics, incomplete antivenom efficacy, and insufficient healthcare provider training.
• Effective strategies necessitate improved public awareness of appropriate first-aid, enhanced clinical care, and the development of evidence-based national guidelines.
• A multi-sectoral approach involving researchers, manufacturers, policymakers, and international funders is crucial for addressing this neglected tropical disease.
