  2. 2. 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!!
  3. 3. 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.
  4. 4. 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.
  5. 5. History Very first swine flu spread on – 1918 as Spanish flu 1957 in Asia 1968-69 in Honkong 2009 in Mexico
  6. 6. 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)
  7. 7. 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.
  8. 8. Starting from the scratch, it is important to know that different species shelter different strains of flu virus
  9. 9. Pigs provide an excellent 'melting pot' for these viruses to mix and match with each other.
  10. 10. Signs & Symptoms             Fever Cough Sore throat Body aches Shortness of breath. Sneezing Runny nose loss of appetite Headache Chills Fatigue Sometimes diarrhea and vomiting
  11. 11. Then, how does it spread?
  12. 12. Being in close proximity with infected pigs
  13. 13. Person to person transmission through coughing or sneezing
  14. 14. Touching something with swine flu influenza on it
  15. 15. Respiratory specimen should be collected within 4 to 5 days of illness.
  16. 16. Testing in laboratory
  17. 17. • • 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)
  18. 18. 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.
  19. 19. Non essential visits to the affected areas should be avoided
  20. 20. Avoid live animal markets, poultry and pig farms in affected countries
  21. 21. Always maintain high levels of personal hygiene
  22. 22. Contact with people from the affected areas should be cautionary
  23. 23. Regular and frequent handwash
  24. 24. Covering sneezes and coughs
  25. 25. Last, but certainly not the least
  26. 26. 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.
  27. 27. THANKS TO ALL
