  3. 3. INTRODUCTION  It is an infection caused by any one of several types of swine influenza viruses.  SIV strains include influenza C and the subtypes of influenza A known as H1N1, H1N2, H2N1, H3N1, H3N2 and H2N3  Swine influenza virus is common throughout pig populations worldwide  People with regular exposure to pigs are at increased risk of swine flu infection
  4. 4.  Swine flu viruses may mutate (change) so that they are easily transmissible among humans.  Vaccination is the best way to prevent or reduce the chances of becoming infected with influenza viruses.  The most serious complication of the flu is pneumonia.
  5. 5. Epidomiology  Swine influenza virus was first isolated from pigs in 1919 and from human in 1974.  In 2009 swine flu outbreak (pandemic) was due to infection with the H1N1 virus and was first observed in Mexico.  In June 2009, the World Health Organization (WHO) raised its pandemic alert level to the highest level, phase 6.  India confirmed its first case on 16 May,2009  According to the data released by the Health Ministry of India,33,761 had been infected and 2,035 person had died.
  6. 6. Electron microscope image of the reassortedH1N1 influenza virus photographed at the CDC Influenza Laboratory. The viruses are 80–120 nm in diameter.
  7. 7. SIGN & SYMPTOMS
  8. 8. TRANSMISSION  Swine influenza caused slightly more infections than would be normal for an influenza season  Coughing  Sneezing  Touching something with flu viruses to your mouth or nose  People who work with poultry and swine, especially those with intense exposures
  9. 9. COMPLICATION  Exacerbation of underlying chronic medical conditions  Upper respiratory tract disease - sinusitis, otitis media, croup  Lower respiratory tract disease - pneumonia, bronchiolitis, status asthmaticus  Cardiac - myocarditis, pericarditis  Neurologic - acute and post-infectious encephalopathy encephalitis  Toxic shock syndrome  Neurologic complications with seizures  Higher Risk Groups for Severe H1N1 Illness
  10. 10.  Effects on pregnancy: The major adverse effect of H1N1 is attributed to hyperthermia during the pregnancy . the risk of neural tube defects and other adverse including neonatal seizures, encephalopathy, cerebral palsy, and neonatal death. This might be treated with the use of antipyretic medications like Acetaminophen and/or multivitamins containing folic acid.
  11. 11. DIAGNOSIS  Laboratory Test - Viral culture  Presence of Virus confirmed by - ELISA(4 fold rise) - RT-PCR  Rapid antigen test(distinguish between influenza A and B)
  12. 12. PREVENTION  Avoid close contact  Stay home when you are sick  Cover the mouth and nose  Clean your hands  Avoid touching your eyes nose or mouth
  13. 13. TREATMENT 1.Symptomatic treatment :  Stay at home  Get plenty of rest  Drink a lot of liquids  Do not smoke or drink alcohol  Consider over-the-counter medications to relieve flu symptoms  Consult a physician early on for best possible treatment
  14. 14. 2) OTC medication : Analgesic,antihistaminic,cough suppressant 3) Antiviral drugs : Antiviral drugs directly target the viruses responsible for influenza infections.
  15. 15. CLASS M2 inhibitor Neuraminidase inhibitors EFFECTIVE AGAINST Influenza A Influenza A & B DRUG NAME amantadine, rimantadine zanamivir, and oseltamivir
  16. 16. CONCLUSION  Swine flu is very rapidly spreading disease  People have to take prophylaxis action like vaccination , safe from contamination etc..  The person suffering from this flu ensure him or her will be cure very soon  Proper medication should be taken
