Understanding Avian Influenza (Bird Flu)
Avian influenza, commonly known as bird flu, is a highly contagious viral infection that primarily affects birds but can also pose serious health risks to humans and other animals. The disease is caused by influenza Type A viruses, which can be found in both wild and domestic bird populations.
How It Spreads
Wild birds, especially waterfowl such as ducks and geese, often carry avian influenza viruses without showing signs of illness. These birds can spread the virus through saliva, nasal secretions, and feces. When domestic poultry such as chickens, turkeys, or ducks come into contact with contaminated surfaces or infected birds, outbreaks can occur rapidly, with devastating consequences for farms and poultry businesses.
Risks to Humans and Animals
While most strains of avian influenza do not infect humans, certain subtypes—such as H5N1 and H7N9—have caused serious illness in people, typically through direct contact with infected birds or contaminated environments. Human-to-human transmission remains rare, but monitoring is essential to prevent potential outbreaks.
Symptoms in Birds
Infected birds may show signs including:
- Sudden death without signs
- Decreased egg production
- Swelling around the head, neck, and eyes
- Respiratory distress (coughing, sneezing, nasal discharge)
- Lack of energy and poor appetite
Preventive Measures
Controlling the spread of avian influenza involves:
- Strict biosecurity measures on farms
- Limiting contact between domestic and wild birds
- Regular monitoring and testing of bird populations
- Immediate reporting and response to suspected cases
