Newcastle disease is a highly contagious viral infection affecting poultry worldwide.
Caused by Avian paramyxovirus type 1, it spreads through direct contact, contaminated equipment, and airborne particles. Infected birds may suffer respiratory distress, neurological issues like tremors or paralysis, reduced egg production, and, in severe cases, sudden death.
Outcomes:
Beyond bird losses, Newcastle disease severely disrupts the poultry industry. Outbreaks lead to culling, trade restrictions, and financial losses for farmers and exporters. Many countries ban imports from affected regions, making disease control crucial for maintaining export markets and stabilising poultry supply chains.
Potential Solutions:
Vaccination is the primary defence against Newcastle disease, reducing severity and spread. Strict biosecurity measures—such as limiting farm access, disinfecting equipment, and controlling wild bird exposure—help prevent outbreaks. Early detection and rapid response, including surveillance and culling, when necessary, are key to minimising damage.
Newcastle disease remains a global challenge, threatening poultry production and international trade. Ongoing research, strong biosecurity, and coordinated efforts between governments and producers are essential to mitigating its impact.
