Bird flu, also known as avian influenza, is a contagious viral infection primarily affecting birds, but it can also pose a risk to humans and other animals. The disease is caused by various strains of the influenza A virus, and its most severe forms can lead to significant outbreaks in poultry populations and, on rare occasions, in humans. To combat this potentially dangerous virus, a range of medicines and treatments have been developed. Antiviral drugs, such as oseltamivir (Tamiflu) and zanamivir (Relenza), are commonly used to treat influenza infections, including those caused by avian strains. These medications work by inhibiting the virus's ability to replicate, thereby reducing the severity and duration of the illness. In addition to antiviral treatments, vaccines are also being researched and developed to provide immunity against specific strains of avian influenza, aiming to prevent outbreaks and safeguard public health.
