Avian Influenza(a.k.a. Bird Flu)
By: Haley Davis,

Slide2Description:
Avian influenza is an infection caused by avian (bird) influenza (flu) A viruses. Avian influenza is very contagious among birds and some of these viruses can make certain domesticated bird species very sick and kill them. Influenza viruses circulating in animals pose threats to human health.
Slide3History
In 1878 a disease capable of causing extremely high mortality among infected birds was first identified as fowl plague.
In 1918 U.S. centers for disease control obtained virus samples from dead bodies of 1918 Spanish flu. It killed from 20 million to 50 million people.
Since 2003, the highly pathogenic avian influenza has spread throughout southeast Asia and to several other regions of the globe.
Slide4Symptoms
Fever
Sore throat
Muscle pain
Eye infections
Pneumonia
Pneumonia leads to viral pneumonia then to multi-organ failure
Nausea
Breathing problems
Slide5TransmissionAvian influenza virus can be transmitted from animals to humans in two main ways:
Directly from birds or from avian influenza virus-contaminated environments to people.
Through an intermediate host, such as a pig
Slide6OriginatedThe A(H5N1) virus subtype virus first infected humans in 1997 during a poultry outbreak in Hong Kong SAR, China. Since its widespread re-emergence in 2003 & 2004, this avian virus has spread from Asia to Europe and Africa and has become entrenched in poultry infections, several hundred human cases, and many human deaths.
Slide7Cures and Treatments
Antiviral medication (
Tamiflu
or
Relenza
)
Intensive supportive care
Special blood tests that detect anti-bodies for the bird flu that are being built during the infection.
To properly treat influenza caused by the H5N1 virus, additional studies still need to be done to demonstrate effectiveness.
