Avian Flu and Its Causes
Avian Flu is virus is called H5N1. Wild birds are host
for the disease but are not affected by it. Wild birds
fly (while migrating) to where there are domesticated
birds like chickens and ducks and infect them. Then
the people living close to the birds get sick.

getting sick.

Treatment of Avian Flu
The Avian Flu is treated like any other flu. To prevent
catching it people should wash their hands and stay
away from infected people. There was a experimental
vaccine made in 2005 but high doses had to be given
and it didn’t always work.

Worries for the Future
The Avian Flu is a disease
that passes from bird to
human. Scientist worry it will
become more contagious and
pass easily from human to
human. The Avian Flu is
related to the Spanish Flu.
Both are Type A influenza
from birds. In 1918 the
Spanish Flu killed over 50
million people.
