Bird flu, or avian influenza, is a viral infection that primarily affects birds but can also spread to humans and animals. The most dangerous strains, H5N1 and H7N9, can cause severe illness. Outbreaks lead to economic losses due to poultry culling and trade restrictions, making global preparedness essential.
The virus spreads through contact with infected birds, their secretions, or contaminated surfaces. Though human-to-human transmission is rare, close contact increases the risk. Migratory birds contribute to its spread, making containment challenging. Strict biosecurity measures in poultry farms and markets are crucial for prevention.
Early detection is key to limiting transmission and improving health outcomes. Symptoms in humans resemble seasonal flu, including fever, cough, and muscle aches, but severe cases can lead to pneumonia, gastrointestinal issues, or neurological complications. Those exposed to infected birds should seek immediate medical evaluation.
Preventative measures include avoiding sick birds, maintaining hygiene, and using protective gear. Poultry vaccination and public health campaigns help control outbreaks. Understanding risk factors and recognizing early symptoms are vital for reducing the virus’s impact. Ongoing vigilance and proactive measures can help protect public health and prevent future outbreaks.
