Is bird flu a danger now in the United States?
No. To date, the highly pathogenic virus that has caused deaths from
avian flu elsewhere has not been detected anywhere in North America.
Even if it is detected in North America, there would be no cause for
panic. The virus is not easily transmitted from person to person. In
most cases, humans were infected through close contact with diseased
poultry, poultry products (feathers, manure, etc.) or contaminated
surfaces, such as dirt, water, or cages.
Since 2003, the
World Health Organization has confirmed 382 cases and 241 deaths from
H5N1 worldwide. These cases were reported from Azerbaijan, Cambodia,
China, Egypt, Indonesia, Iraq, Thailand, Turkey, and Vietnam. Seasonal
flu is far more dangerous by comparison: the Centers for Disease
Control estimates that complicatoins from seasonal flu cause about
36,000 deaths each year in the United States alone, mostly among the
elderly.
The only documented cases of transmission of the highly
pathogenic H5N1 virus from wild birds to humans is in Azerbaijan. Seven
people became ill after defeathering swans, four of whom later died.
For more information about this case, read the June 26, 2006 article in
The Guardian.
There
have only been a few suspected cases of human-to-human infection,
limited to those who were in close contact with a patient presumed to
have contracted the illness from poultry. However, health officials are
concerned about the potential for the virus to mutate into a form that
is more easily spread from person to person. Such mutations are most
likely to occur in the poultry industry, where the virus can spread
through large flocks of susceptible birds, and where human workers have
prolonged contact with poultry.
