Snakebites in India – A Public Health Challenge

Snakebites are public health issue in India. The Union Health Ministry has emphasised the need to classify snakebites as a notifiable disease. This classification allows for better tracking and management of cases. Each year, India reports three to four million snakebite incidents, resulting in approximately 58,000 deaths. The National Action Plan for Prevention and Control of Snakebite Envenoming (NAPSE) aims to reduce these fatalities by 2030.

Notifiable Diseases

Notifiable diseases are those that must be reported to health authorities. This includes infections that could lead to outbreaks or deaths. Examples include tuberculosis, HIV, cholera, and malaria. The list varies by state, as local governments determine what constitutes a notifiable disease. The move to classify snakebites as notifiable aims to enhance surveillance and response.

Medical Importance of Snakebites

Snakebites are considered medical emergencies. They can cause severe symptoms such as paralysis and haemorrhage. Immediate treatment is crucial. Antivenoms are essential to prevent fatalities. In India, there are 66 venomous snake species, with 23 deemed medically . The “Big Four” snakes responsible for the majority of bites are the Indian cobra, common krait, Russell’s viper, and saw-scaled viper.

Rationale for Notifiable Status

The Centre advocates for snakebites to be notifiable to improve data collection. Accurate statistics on cases and deaths will aid in resource allocation. This includes ensuring adequate antivenom supplies and training healthcare workers in high-risk areas. The goal is to enhance clinical management and reduce fatalities.

Challenges in Treatment

Challenges in treating snakebites include delayed medical care. Many victims seek traditional healers instead of hospitals. Additionally, healthcare staff often lack training in snakebite management. There is also a lack of diagnostic tests to confirm snakebites.

Antivenom Limitations

Antivenoms in India are primarily derived from snakes caught by the Irula tribe. However, venom potency can vary geographically. This means that antivenoms may not always be effective. Furthermore, local species in regions like Northeast India may not respond to commercially available antivenoms. Researchers are exploring new treatments, including artificially produced antibodies and peptides.

Venom Collection Issues

Experts recommend establishing venom collection banks to address regional differences in snake venom. However, legal restrictions under the Wildlife (Protection) Act of 1972 hinder these efforts. This limits access to snake specimens needed for antivenom development.

Future Directions

To combat the snakebite crisis, comprehensive strategies are essential. This includes improved surveillance, enhanced training for healthcare providers, and innovative research on antivenoms. Collaborative efforts will be crucial in addressing this public health challenge effectively.

Questions for UPSC:

1. Critically analyse the impact of snakebites on public health in India.

4. Comment on the role of local communities in managing snakebite incidents and improving healthcare access.

Answer Hints:

1. Critically analyse the impact of snakebites on public health in India.

1. Annually, India experiences 3-4 million snakebite cases, leading to approximately 58,000 deaths.
2. Snakebites are prevalent in densely populated, low-altitude agricultural areas, affecting rural communities .
3. The National Action Plan for Prevention and Control of Snakebite Envenoming (NAPSE) aims to halve fatalities by 2030.
4. Economic burden includes healthcare costs and loss of productivity among affected individuals and families.
5. Inadequate healthcare infrastructure exacerbates the issue, with many victims not receiving timely medical care.

2. What are the challenges faced in the treatment of snakebites? Explain with examples.

1. Delayed medical care is common, as many victims seek traditional healers instead of hospitals.
2. Healthcare staff often lack specialized training in snakebite management, leading to inadequate treatment.
3. Diagnostic tests for confirming snakebites are not widely available, complicating treatment decisions.
4. Antivenom supply is inconsistent, particularly in high-risk areas, leading to treatment delays.
5. Geographical differences in venom potency can affect treatment outcomes, as seen with local snake species in Northeast India.

3. What is the significance of antivenom in snakebite treatment? How does geographical variation affect its efficacy?

1. Antivenom is crucial for neutralizing snake venom and preventing death or severe symptoms.
2. In India, antivenoms are primarily derived from venom collected from specific snake species, mainly by the Irula tribe.
3. Geographical variation in snake venom can lead to differences in potency, affecting the effectiveness of antivenoms.
4. Some local species may not respond to commercially available antivenoms, denoting the need for region-specific treatments.
5. Research is ongoing to develop new therapies, including artificially produced antibodies to improve treatment efficacy.

4. Comment on the role of local communities in managing snakebite incidents and improving healthcare access.

1. Local communities play important role in initial response and management of snakebite incidents.
2. Community awareness and education can lead to better prevention strategies and reduce snakebite occurrences.
3. Collaboration with healthcare providers can improve access to timely treatment and antivenoms.
4. Community health workers can be trained to recognize symptoms and provide first aid before professional help is available.
5. Engagement of local populations in venom collection efforts could enhance antivenom development and availability.
