Learn More3. **Transmission**: NDV spreads through direct contact with infected birds, contaminated equipment, feces, or respiratory secretions. Wild birds can also carry and transmit the virus.
4. **Symptoms**: Infected birds may exhibit a range of symptoms, including respiratory distress, greenish diarrhea, depression, nervous signs (such as tremors, twisting of the neck), and a drop in egg production or quality.
5. **Classification**: ND is classified into different strains based on virulence. Lentogenic strains cause mild or asymptomatic infections, mesogenic strains cause moderate symptoms, and velogenic strains are highly virulent and can cause severe disease with high mortality rates.
6. **Impact**: ND has significant economic implications due to its ability to cause high mortality rates in poultry populations, leading to production losses and trade restrictions.
7. **Prevention and Control**: Vaccination is a key strategy for preventing Newcastle disease. Vaccines are available for different strains, and vaccination programs vary depending on the risk level and the type of poultry production.
8. **Biosecurity Measures**: Strict biosecurity measures, such as limiting access to poultry facilities, disinfection protocols, and controlling movement of birds and personnel, are crucial for preventing ND spread.
9. **Global Concern**: Newcastle disease is a global concern, with outbreaks reported in various regions. Monitoring, reporting, and coordinated control efforts are essential for managing and containing the disease.

10. **One Health Approach**: Given the zoonotic potential of some NDV strains and the interconnectedness of animal and human health, a One Health approach that integrates veterinary, public health, and environmental perspectives is important for effective ND management and prevention of potential spillover events.
