Swine Flu - A Brief Awareness Powered By Docstoc
					Swine flu is believed to be originated in Mexico and is known as such as
the majority of genes present in the virus are regular Swine flu genes,
even though it also contains human and avian flu genes as well. The
symptoms are identical to those of normal flu such as runny nose, fever,
coughing and body aches. However, some victims experience vomiting and
diarrhea as well, and disease gets spread similar to seasonal flu.
The popular myth earlier was that people eating pork or pork products
contracted this virus, but this proved to be incorrect. The fear of being
another verge of pandemic, swept the entire world, but was immediately
proved that it did not occur even due to water contamination; and in
reality it is an airborne respiratory disease.

  Swine flu evolved as a critical ailment, now it has been identified,
diagnosed and accordingly proper treatment is given. The disease is
diagnosed clinically taking into consideration the people with whom the
patient has association, and if they have this ailment or symptoms. This
is done by taking a quick test called nasopharyngeal swab sample to see
if that person is infected with influenza virus A or B.      The tests
can also be negative indicating no flu infection or can give positive
results indicating A or B virus. In case this test proves to be positive
indicating B type influenza virus, it is safe as it is not Swine flu. A
positive result indicating A type virus can result in that person having
conventional flu or Swine flu. The accuracy of such tests is challenging,
and owing to this, a comparative study is being done. Recently, CDC has
reported that Swine flu can be detected in an hour; however, right now it
is available only to the military.      Swine flu is diagnosed by taking
a test in a specialized laboratory and the best treatment available now
is prevention by vaccination. The effort and work by many laboratories
has resulted in producing vaccines to prevent the disease and the first
vaccine was a nasal spray vaccine released in October, 2009. This vaccine
has been approved for all age group individuals from 2 to 49, except for
pregnant women who are not recommended to inject this vaccine.
However, another injectable vaccine made using killed H1N1 became
available from October second week, and is approved from 6 months child
to elderly, besides including pregnant females. These vaccines have
received approval by the CDC only after undergoing clinical trials in the
aim of proving that these vaccines are safe as well as effective.
However, this does not overrule the fact that caregivers need to be aware
of the guidelines of injecting this vaccine.      There has been a report
that two antiviral agents, Tamilflu (Oseltamivir) and Relenza (Zanamivir)
help in reducing Swine flu affects and also prevent the A and B influenza
symptoms. However, indiscriminate use of these drugs should be
restricted, besides these drugs are not recommended for people suffering
with flu symptoms for over 48 hours or more. Conversely, patients facing
severe infections may need additional measures like ventilation
assistance and treatment of infections such as pneumonia occurring in
patients with flu infection. There are interim guidelines suggested by
the CDC for pregnant females to the given treatment using two antiviral
agents.      You can have access to articles about health in portuguese
