									Bird Flu- Prevention and Treatments      Bird flu is turning out to be a
terror for Asian countries; the epidemic is growing    rapidly which is a
matter of concern for the U.S. Government. The recent out break    has the
potential to become a human    flu pandemic.     As per recent updates
Bird Flu has taken the lives of almost 50 people in Southeast    Asia and
resulted in the deaths of millions of poultry. The virus can be a serious
threat if it develops the capacity of easy transmission from one person
to another.       Bird flu symptoms    Bird flu symptoms are like any
other flu's. The symptoms worsen to become a severe    respiratory disease
that has been fatal in a high percentage of cases.     In February 2005,
researchers in Vietnam reported human cases of bird    flu in which the
virus infected the brain and digestive tract of two children.    Both
ultimately died after a few days of struggle. Hence, this proves that the
bird flu may start like any other flu but more often than not is fatal.
Fortunately, no human cases of bird flu have been seen in the U.S. or
North America.   Yet as a precaution, the CDC is asking people who have
traveled to East Asia to    see a doctor if they develop flu-like
symptoms. It's important to tell the doctor    about having visited these
areas so the proper tests can be done. Prevention is    better than cure.
Avian Flu Treatment The current bird flu strain is immune to older flu
drugs. However, the drug remains    sensitive to the newer flu drugs
Tamiflu and Relenza. However, supplies remain    short. Unfortunately
there's only one plant making Tamiflu - and the U.S. isn't    the only
country desperately trying to build up a stockpile. Other countries,
such as Britain, have also started stockpiling the drug.     Antiviral
drugs, some of which can be used for both treatment    and prevention, are
clinically effective against influenza. But these drugs too    have some
limitations.     Avian Flu Vaccine    At least four months would be needed
to produce a new vaccine, in significant    quantities, capable of
conferring protection against a new virus subtype. Such    a vaccine will
not be easy to produce, as the virus kills the chicken eggs usually
used to mass-produce flu vaccines. One approach being contemplated is to
produce   the vaccine from a similar (but not egg-killing) strain
isolated from ducks in   Singapore in 1997.
