Tamil Nadu Declares Snakebite Envenomation a Notifiable Disease

Context: The Tamil Nadu government has officially designated snakebite envenomation as a notifiable disease under the Tamil Nadu Public Health Act, 1939. This move aims to enhance the reporting, response, and treatment of snakebite cases across the state.

About Snakebite Envenomation:

• Snakebite envenomation is a life-threatening condition caused by bites from venomous snakes. It can result in severe complications, including:
  • Paralysis that can impair breathing.
  • Bleeding disorders that may lead to fatal hemorrhaging.
  • Irreversible kidney failure.
  • Severe tissue damage at the bite site.
• The most effective treatment is high-quality antivenom, which can counteract or reverse many of the venom's toxic effects.

Global Impact:

• An estimated 5.4 million people worldwide are bitten by snakes each year, with 1.8 to 2.7 million cases leading to envenomation.
• Vulnerable groups include agricultural workers, children, and residents in tropical and subtropical regions.

WHO’s Response:

• The World Health Organization (WHO) recognizes snakebite envenomation as a global public health issue and has implemented a strategy to reduce snakebite-related deaths and disabilities worldwide.

Snakebite Situation in India:

• India is home to over 310 snake species, with the majority being non-venomous.
• Of these, 66 species are classified as venomous or mildly venomous. Most snakebite incidents involve the "Big 4" species:
  • Russell’s viper (Daboia russelii)
  • Spectacled cobra (Naja naja)
  • Common krait (Bungarus caeruleus)
  • Saw-scaled viper (Echis carinatus)

National Action Plan:

• The Ministry of Health and Family Welfare recently launched the National Action Plan for Prevention and Control of Snakebite Envenoming.
• This plan aims to halve snakebite deaths by 2030 through a ‘One Health’ approach that integrates human, animal, and environmental health interventions.

Tamil Nadu’s New Initiative:

• By designating snakebite envenomation as a notifiable disease, Tamil Nadu seeks to improve data collection and strengthen healthcare response across the state.
• Key goals include:
  • Enhancing clinical infrastructure for snakebite treatment.
  • Ensuring efficient distribution of antivenom to healthcare facilities.
  • Reducing mortality rates and improving treatment accessibility.
• Under this initiative:
  • Both government and private hospitals are required to report all snakebite cases and related deaths.
  • The reporting system will integrate with the State’s Integrated Health Information Platform under the Integrated Disease Surveillance Program.

Addressing Underreporting:

• Authorities have identified significant underreporting of snakebite cases and deaths in previous data.
• This new reporting system aims to close data gaps, allowing for more accurate tracking and better resource allocation to address snakebite envenomation in Tamil Nadu.

In Summary: Tamil Nadu’s declaration of snakebite envenomation as a notifiable disease marks a crucial step in improving snakebite management, accessibility to treatment, and prevention in high-risk areas, ultimately aiming to reduce mortality and strengthen public health response.
