Avian influenza
Avian Influenza
Avian influenza (pronounced: /ˈeɪviən ˌɪnfluˈɛnzə/), also known as bird flu, is an infectious type of influenza that spreads among birds. In rare cases, it can affect humans.
Etymology
The term "avian influenza" comes from the Latin word avis, meaning "bird", and the Italian word influenza, meaning "influence". The term was first used in the early 20th century to describe a flu-like illness that affected poultry.
Symptoms
In birds, symptoms of avian influenza can range from mild illness to severe disease, which can lead to death. Symptoms can include decreased egg production, respiratory signs such as coughing and sneezing, and neurological signs such as tremors and lack of coordination.
In humans, symptoms of avian influenza can range from typical flu symptoms (such as fever, cough, sore throat, and muscle aches) to severe respiratory illness (such as pneumonia and acute respiratory distress).
Transmission
Avian influenza viruses can be transmitted directly from wild birds to domestic poultry or to humans through direct contact with infected birds or contaminated environments. In rare cases, avian influenza can spread from person to person.
Prevention and Control
Prevention and control measures for avian influenza include surveillance, improved biosecurity, rapid diagnosis, and vaccination.
