4. Introduction
An epidemic of a new strain of influenza virus identified in
april 2009- influenza A (H1N1) virus ,which commonly
referred to as “Swine Flu." The World Health Organization
(WHO), has raised its pandemic alert level to “Phase 5”
out of the six maximum, as a "signal that a pandemic is
imminent" .
More than 13400 people has been infected by this virus.
Around 200 people died all over the world among them
there was a Bangladeshi!!

5. SWINE FLU
Swine flu is an acute viral infection
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
viruses spread.

6. 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
Reassortant” virus.

7. History
Very first swine flu spread on –
1918 as Spanish flu
1957 in Asia
1968-69 in Honkong
2009 in Mexico

8. What is new a`bout Swine
flu?
The new strain is an apparent reassortment of
four strains of influenza A virus subtype H1N1.
Analysis by the CDC identified the four
component strains as
one endemic in humans,
one endemic in birds and
two endemic in pigs (swine)

9. 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.

10. Starting from the scratch, it is important
to know that different species shelter
different strains of flu virus

11. Pigs provide an excellent 'melting pot'
for these viruses to mix and match with
each other.

14. Signs & Symptoms


Fever
Cough
Sore throat
Body aches
Shortness of breath.
Sneezing
Runny nose
loss of appetite
Headache
Chills
Fatigue
Sometimes diarrhea and
vomiting

15. Then, how does it spread?

16. Being in close
proximity with
infected pigs

17. Person to person transmission through
coughing or sneezing

18. Touching something with swine flu
influenza on it

20. Respiratory
specimen should
be collected
within 4 to 5 days
of illness.

21. Testing in laboratory

22. •
•
Antiviral drugs for seasonal
influenza are available in some
countries to effectively treat the
illness.
There are two classes of such
medicines
1) Adamantanes
Amantadine and
Remantadine
2) Inhibitors of influenza
neuraminidase
Oseltamivir
(Tamiflu)
Zanamivir(Relenza)

24. Is there a vaccine against swine
influenza?
There is a vaccine
available for pigs
against swine influenza,
but there is no vaccine
to protect humans from
current swine influenza.

25. Non essential visits to the affected
areas should be avoided

26. Avoid live animal markets, poultry
and pig farms in affected countries

27. Always maintain high levels of
personal hygiene

28. Contact with people from the affected
areas should be cautionary

29. Regular and frequent handwash

30. Covering sneezes and
coughs

32. Last, but certainly not the least

33. Contribution of computer
scientists
Doctors and computer
scientists are working
together in order to fight
against swine flu .
They have made a virtual city
and inputting real data
everyday .And taking
effective decisions toward
swine flu for real world from
it.
