of the respiratory tract in pigs caused
by type A influenza virus.
This new influenza virus causing
illness in people.This virus is
spreading quickly from person-toperson, probably in much the same
way that regular seasonal influenza
Why is this virus sometimes
called “Swine Flu”??
This virus is referred to as “swine flu” because many of
the genes in this virus were very similar to influenza
viruses that normally occur in pigs in North America.
But further study has shown that this new virus has
two genes from flu viruses that normally circulate in
pigs in Europe and Asia and avian avian genes and
human genes. Scientists call this a “Quadruple
Very first swine flu spread on –

Analysis by the CDC identified the four
component strains as
one endemic in humans,
one endemic in birds and
two endemic in pigs (swine)
What is new about Swine flu…
Flu viruses have the ability to swap genetic
components with each other. The new version of
H1N1 resulted from a mixing of different
versions of the virus, which may usually affect
different species, in the same animal host.
Starting from the scratch, it is important
to know that different species shelter
different strains of flu virus
Pigs provide an excellent 'melting pot'
for these viruses to mix and match with
