  • What are pandemics? Pandemics are when a new influenza A emerges to which most or many of the population have no immunity. The result usually from an animal influenza combining some of its genes with a human influenza. To be a pandemic strain an influenza A virus needs to have three or four characteristics. They need to be able to infect humans, to cause disease in humans and to spread from human to human quite easily. An additional criteria that is often applied is that many or most of the population should be non-immune to the new virus. <br /> Note this animated slide was first developed by the National Institute of Infectious Disease in Japan and we are grateful to them and especially Masato Tashiro for letting us use it. <br />
  • But remember this is idealised – and in 2009 in North America this is not putting as many people into Hospital as you would expect from the above. In the 2009 pandemic it is not clear yet what percentage are asymptomatic. Two reasonable estimates are 33% and 50% of the total infected. [Note to Uwe – can you increase the asymptomatic fraction in both to make them look about 33% of the total] <br />
  • The three pandemics of the 20th century show how these known unknowns can result in important changes. More detail on the different pandemics are available at http://ecdc.europa.eu/en/Health_Topics/Pandemic_Influenza/stats.aspx. <br />
  • The influenza virion is an enveloped virus that derives its lipid bilayer from the plasma membrane of a host cell. Two different varieties of glycoprotein spike are embedded in the envelope. Approximately 80 percent of the spikes are hemagglutinin, a trimeric protein that functions in the attachment of the virus to a host cell. The remaining 20 percent or so of the glycoprotein spikes consist of neuraminidase, which is thought to be predominantly involved in facilitating the release of newly produced virus particles from the host cell. On the inner side of the envelope that surrounds an influenza virion is an antigenic matrix protein lining. Within the envelope is the influenza genome, which is organized into eight pieces of single-stranded RNA (A and B forms only; influenza C has 7 RNA segments). The RNA is packaged with nucleoprotein into a helical ribonucleoprotein form, with three polymerase peptides for each RNA segment. <br />
  • For the most current number of human cases visit the CDC H1N1flu website: http://www.cdc.gov/h1n1flu/investigation.htm. <br /> CDC, along with state and local health agencies, are working together to investigate this situation. <br /> Numbers are updated every at 11:00 AM EDT. <br />
  • It is thought that the main way influenza viruses are spread from person to person is through transmission of respiratory droplets during coughing and sneezing. Close contact (about 3 feet or less) usually is necessary for this type of spread. Influenza viruses also can spread by touching respiratory droplets on yourself, others, or an object, then touching mucus membranes, such as the mouth, nose, or eyes, without washing contaminated hands. <br />
  • In addition of sign and symptom of <br />
  • contact with suspected, probable or confirmed cases <br />
  • “If there is 25 or more epidemiologically linked suspect cases of Pandemic Influenza A H1N1 of which at least one or more are laboratory confirmed for Pandemic Influenza A H1N1, in two or more cities, over a period of two weeks, then the State would be considered to be having community spread” <br /> . <br />
  • C/I in person sufferinf from rspiratory and cardiac ds <br />
  • Each year, experts from Food and Drug Administration (FDA), World Health Organization (WHO), U.S. Centers for Disease Control and Prevention (CDC) and other institutions study virus samples collected from around the world. They identify the influenza viruses that are the most likely to cause illness during the upcoming flu season so that people can be protected against them through vaccination. <br />
  • Flu virus are costantly changes (Ag drift), so its not possible to predict ehich flu virus predominate during a given year <br />
  • Children shed virus for longer duration, suspect !!!! <br />
  • Leave the room <br /> Once outside room use alcohol hand-rub again or wash hands with soap & water <br />
  • The masks have numbers beside them that indicate their filtration efficiency. For example, a N95 mask has 95% efficiency in filtering out particles greater than 0.3 micron under normal rate of respiration <br /> The next generation of masks use Nano-technologywhich are capable of blocking particles as small as 0.027 micron. <br />

  • Introduction  Epidemiology  Sign and symptom  Diagnosis  Treatment  Prevention 
  • WHAT IS SWINE FLU  Swine influenza Refers to influenza cases that are caused by Orthomyxovirus endemic to pig populations. Is a respiratory disease of pigs caused by type A influenza Regularly cause outbreaks among pigs. Swine flu viruses do not normally infect humans
  • VIRAL INFLUENZA A - HUMAN HISTORY 1889-90 1900-03 1918-19 H2N8 H3N8 H1N1(HswN1) Severe epidemic Mod epidemic Severe epidemic 1933-35 1946-47 1957-58 H1N1(HON1) H1N1 H2N2 Mild epidemic Mild epidemic Severe epidemic 1968-69 1977-78 H3N2 H1N1 Mod epidemic Mild epidemic
  • OR Y H IS T The H1N1 form of swine flu is one of the descendants of the Spanish flu that caused a devastating pandemic in humans in 1918–1919 In 1957, an Asian flu pandemic infected some 45 million Americans and killed 70,000. It caused about 2 million deaths globally Eleven years later, lasting from 1968 to 1969, the Hong Kong flu pandemic afflicted 50 million Americans and caused 33,000 deaths In 1976, about 500 soldiers became infected with swine flu over a period of a few weeks.

  • INFLUENZA VIRUS  Three types of influenza viruses: A, B and C.  A and B  seasonal epidemics of disease  C infections mild respiratory illness and are not thought to cause epidemics. 
  • ORTHOMYXOVIRUSES 80-200nm HA - hemagglutinin –attaches to sialic Acid receptor NA – neuraminidase-helps in Budding out of infected cell helical nucleocapsid (RNA plus NP protein) lipid bilayer membrane polymerase complex M1 protein type A, B, C : NP, M1 protein sub-types: HA or NA protein
  • INFLUENZA -A  Two proteins on the surface of the virus  Hemagglutinin  16 subtypes  Neuraminidase  (H) 09 subtypes (N)
  • CLASSIFICATION= The antigenic type (e.g., A, B, C)  The host of origin (e.g., swine, equine, chicken, etc. For human-origin viruses, no host of origin designation is given.)  Geographical origin (e.g., Mexico, Taiwan, etc.)  Strain number (e.g., 15, 7, etc.)  Year of isolation (e.g., 57, 2009, etc.) 
  • PATHOPHYSIOLOGY  Antigenic drift  Mutations within the virus antibody-binding sites accumulate over time  Circumvent the body's immune system  A and B  Antigenic shift  Sudden change in antigenicity  Recombination of the influenza genome  Cell becomes simultaneously infected by two different strains of type A influenza.  Humans live in close proximity swine, that human strains and bird strains, may readily infect a pig at the same time, resulting in a unique virus.
  • ANTIGENIC SHIFT H1N1
  • NOVEL H1N1 INFLUENZA  The first cases of human infection with novel H1N1 influenza virus were detected in April 2009 in San Diego and Imperial County, California and in Guadalupe County, Texas.  The virus has spread rapidly.  The virus is widespread in the United States  Has been detected internationally as well.
  • WHO CAN CATCH THE “FLU” ?
  • WHO CAN CATCH THE FLU ? As in all epidemics Children Elderly Pregnant women Immuno-suppressed or Immuno-compromised Chronic medical conditions Occupational exposure-paramedics, medics
  • HOW DOES NOVEL H1N1 INFLUENZA SPREAD?  spread the same way seasonal flu spreads  Primarily through respiratory droplets  Coughing  Sneezing  Touching respiratory droplets on yourself, another person, or an object, then touching mucus membranes (e.g., mouth, nose, eyes) without washing hands
  • CAN YOU GET NOVEL H1N1 INFLUENZA FROM EATING PORK? No You cannot get novel H1N1 flu from eating pork or pork products. Eating properly handled and cooked pork products is safe.

PROBABLE CASE is defined as a person with an acute febrile respiratory infection who tests positive for influenza A but negative for H1 and H3 by viral RT-PCR.
  • SUSPECTED CASE is defined as a person with an acute febrile respiratory infection with onset Within 7 days of close contact with a person who is a confirmed case of S-OIV infection. Within 7 days of travel to a community where there are one or more confirmed cases. Resides in a community where there are one or more confirmed cases of SIV infection.
  • INFECTIOUS PERIOD for a confirmed case of H1N1 is defined as 1 day prior to the cases illness onset to 7 days after onset. CLOSE CONTACT is defined as being within 6 feet of a confirmed or suspected case of H1N1 during the case’s infectious period. ACUTE ONSET OF A RESPIRATORY ILLNESS is defined as having at least 2 of the following: rhinorrhea, sore throat and cough with or without fever

  • DIAGNOSTIC ASSAYS  Real-time reverse transcriptase (rRT)-PCR  most  sensitive and specific test culture  too slow  A negative viral culture does not exclude pandemic H1N1 influenza A infection.
  • LIMITATIONS Analysts should be trained and familiar with testing procedures and interpretation of results prior to performing the assay.  A false negative result may occur if inadequate numbers of organisms are present in the specimen due to improper collection, transport or handling. 
  • DIAGNOSTIC ASSAYS Combined nasopharyngeal and throat swabs (CNTS)  Nasopharyngeal aspirates (NPA) 
  • DIAGNOSTIC ASSAYS  Rapid antigen tests  Distinguish between influenza A and B viruses  Cannot distinguish among different subtypes of influenza A  sensitivity -10 to 70 percent  specificity of rapid antigen testing was generally >95 percent
  • DIAGNOSTIC ASSAYS  Immunofluorescent antibody testing   Direct or indirect immunofluorescent antibody testing (DFA or IFA)  Distinguish between influenza A and B  does not distinguish among different influenza A subtypes  Low sensitivity and specificity
  • METHOD Acceptable Specimens Test Time Viral cell culture NP swab, throat swab, NP ,bronchial wash, nasal endotracheal aspirate, sputum 3-10 days Direct (DFA) or Indirect (IFA) Antibody NP swab or wash, bronchial wash, nasal or endotracheal aspirate 1-4 hours RT-PCR NP swab, throat swab, NP or bronchial wash, nasal or endotracheal aspirate, sputum 1- 6 hours Rapid Influenza Diagnostic Tests NP swab, (throat swab), nasal wash, nasal aspirate <30 min.

  • Respiratory Hygiene/Cough Etiquette • Covering your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use • Wash hand
  • Touching face regions can faster the Spread • Avoiding touching your eyes, nose or mouth. Virus can spread this way in a faster way
  • Staying home if you are sick
  • Avoid crowded places more so with young children
  • Mild cold like symptoms - Take rest
  • Using N95 mask reduces the Risk • You can cut your risk of contracting the flu or other respiratory viruses by as much as 80 percent by wearing a mask over your nose and mouth Emerging Infectious Diseases, the journal of the Centres for Disease Control and Prevention (CDC) .
