Trans-boundary animal diseases pose a unique challenge to India's livestock economy and biosecurity. Discuss with reference to African Swine Fever.

Trans-boundary animal diseases (TADs) spread across national borders through animal movement and trade, demanding coordinated rather than local responses. African Swine Fever (ASF), a highly contagious viral disease of pigs with mortality approaching 100% and no treatment [3], first detected in India in 2020 [1], illustrates this challenge sharply.

Why TADs are a unique challenge

• No cure, only containment: ASF has no treatment; control rests on culling, movement restrictions and biosecurity, making outbreaks economically punitive by design [3].
• Environmental persistence: ASF virus survives on clothing, footwear, vehicles and in processed pork products, so infection travels through trade and human activity, not just animals [3].
• Regional contagion: ASF has swept across Asia and the Pacific since 2018, so India's risk is set by its neighbourhood, not its borders alone [4].

Impact on India's livestock economy

• Concentrated losses: Assam lost about ₹276 crore (2020–21) and Mizoram about ₹982 crore, affecting over 11,000 households [1].
• Livelihood and social cost: piggery is a mainstay of smallholder and tribal households in North-East India, where pork is a staple protein — losses translate directly into nutritional and income shocks [1].
• Trade and market shock: culling and movement bans disrupt local pork markets well beyond infected herds.

Biosecurity response and indigenous capacity

• Institutional capacity: ICAR-NIHSAD, Bhopal, India's high-security animal disease facility, developed the country's first indigenous live-attenuated ASF vaccine on the widely available MA-104 cell line, keeping costs low [1][2].
• Surveillance tools: a Digital Swine Disease Atlas was released alongside it to strengthen disease monitoring [2].
• Proven track record: builds on indigenous veterinary vaccine work such as ICAR-IVRI's Classical Swine Fever vaccine [5].

ASF shows that livestock disease is simultaneously an economic, livelihood and biosecurity question. An affordable indigenous vaccine, paired with farm-level biosecurity, rapid diagnostics and regional cooperation, converts a reactive culling model into preventive protection — advancing self-reliance in veterinary biologicals and rural livelihood security alike.
