Newcastle disease is a lorrot infection that results in a disease killed and is highly infectious, particularly in the dicks as chickens, shells. It can lead to severe damage to the global bird industry because it causes a rapidly high death rate and financial loss. Information regarding the disease, as it might transmit it, is highly crucial for farmers, veterinarians, and individuals practical bread.
What Is Newcastle Disease?
The Newcastle Disease virus, a Paramyxovirus family member, causes Newcastle’s (ND). Newcastle disease can affect wild birds and wild birds, with wild levels being based on a viral strip. Certain trunks bring a sudden respiratory disease, while others can bring sudden death in large bird of birds.
ND is a notifiable disease in most countries, such that outbreaks are reported to the government agencies to curb its spread.

Symptoms of Newcastle Disease
Symptoms of Newcastle Disease may differ depending on the type of strain of the virus, as well as the type of infected bird. But common signs are:
- Respiratory signs: Sneezing, coughing, nasal discharge, and breathing problems
- Nervous signs: Trembling, curled necks, paralysis, and loss
- Digestive signs: Diarrhea and decreased feed intake
- Reproductive issues: Acute reduction in egg laying or laying of soft-shelled/misshapen eggs
- Abrupt death, particularly in more virulent forms
Signs typically set in between 2 to 15 days following exposure.

How Is It Spread?
Newcastle Disease is mainly spread through direct contact with the infected birds or their discharges (saliva, feces, nasal discharge). Indirect transmission is also possible through:
- Infected feed and water
- Equipment, attire, and shoes
- Wild birds or rodents that have contact with poultry rooms
- Airborne particles in crowded or closed poultry houses
The virus is extremely resilient and will last for weeks in the environment under some conditions, and is a long-term hazard.
Economic and Public Health Impact
Newcastle Disease does not threaten human health (it causes only mild conjunctivitis or flu-like illness in exceptional cases), yet its effects on the poultry sector are devastating. Its outbreaks result in:
- High levels of flock mortality
- Widespread culling of exposed and infected birds
- Quarantines and trade restrictions
- Economic losses for producers and farmers
Where poultry farming is a significant economic activity in a region, ND can be catastrophic.
Vaccination Schedule for Broiler Chicks
Prevention and Control
There is no treatment for Newcastle Disease, and prevention is therefore the most important approach. The major preventive steps are:
1. Vaccination
Regular vaccination is the best method to immunize poultry against ND. Various vaccine types (live attenuated and inactivated) are employed based on the region and the production system.
2. Biosecurity Measures
- Limit access to poultry houses
- Disinfect vehicles, clothing, and equipment
- Employ footbaths and hand sanitizers
- Prevent the intermingling of household poultry and free birds
3. Early Reporting and Detection
Early detection and reporting of the symptoms assist in quick containment and limit the spread.
4. Safe Disposal of Dead Birds
Dead or culled birds have to be disposed of safely by burning, burial, or rendering to avoid further contamination.
Global Efforts to Eradicate Newcastle Disease
It is linked with governments and regional organizations since the organization of the World Health Organization (WHO) and the organization of diseases caused by illness. The prompting vaccination, education, and reinforcement are crucial to decrease the world’s impact.
Final Thoughts
Newcastle Disease is still among the most dangerous viral poultry diseases in the world. Poultry farmers need to adopt strict biosecurity measures and join vaccination campaigns. Awareness, early detection, and collaborative response can go a great way towards controlling and ultimately eliminating this fatal disease.
