Avian Influenza

Avian influenza, also known as bird flu, is a viral respiratory disease primarily affecting birds, including chickens, turkeys, ducks, and geese. It can also cause serious illness in humans. The viruses that cause avian influenza have different subtypes and can range in severity, from mild to highly pathogenic. Highly pathogenic avian influenza viruses are capable of causing widespread illness and death among domestic poultry and wild birds, and can lead to severe economic losses for poultry producers and governments. The primary way in which avian influenza viruses spread is through direct contact with infected birds and their secretions. Avian influenza viruses can also be spread indirectly through contaminated surfaces, feed, and water, as well as through contact with humans who have been in contact with infected birds. The World Health Organization (WHO) monitors the situation and provides advice and guidance to governments about prevention, control, and containment measures for avian influenza.
