					What is SWINE FLU?
 Swine Influenza (swine flu) is a respiratory disease of
 pigs caused by type A influenza virus that regularly
 causes outbreaks of influenza in pigs. Swine flu viruses
 cause high levels of illness and low death rates in pigs.

 Swine flu viruses do not normally infect humans.
 However, sporadic human infections with swine flu
 have occurred. Most commonly, these cases occur in
 persons with direct exposure to pigs
HISTORY
 1918 pandemic in humans

 1976 U.S. outbreak

 1988 zoonosis

 1998 US outbreak in swine

 2007 Philippine outbreak in swine

 2009 outbreak in humans
 For the following 60 years, swine influenza strains
 were almost exclusively H1N1, later other strains
 emerged as a result of reassortment of genes derived
 from human, swine and avian viruses.

 Swine influenza virus was first isolated from humans
 in 1974.
WHY IS H1N1 FLU CALLED SWINE
FLU?
 The H1N1 viral strain implicated in the 2009 pandemic
 flu among humans often is called "swine flu virus"
 because initial testing showed many of the genes in
 the virus were similar to influenza viruses normally
 occurring      in     North     American      swine.

 But further research has shown that the outbreak is
 due to a new strain of H1N1 not previously reported in
 pigs.
PANDEMIC H1N1…
SWINE FLU & INDIA
               Total Confirmed Cases in
               India 5,221*

               Total Deaths in India 138*

Pandemic Influenza Phases
How did this virus come to INDIA?
 The      outbreak       began       in       Mexico.

 In early June, as the virus spread globally, the WHO
 declared the outbreak to be a pandemic, but also
 noted that most illnesses were of “moderate severity.”

 The  virus has since spread to the Southern
 Hemisphere which entered its winter flu season, and
 to many less developed countries with limited
 healthcare systems.
HOW DOES H1N1 SPREAD?


             DROPLET INFECTION
How severe is illness associated
with 2009 H1N1 flu virus?
 Illness with the new H1N1 virus has ranged from mild to
  severe. While most people who have been sick have
  recovered     without   needing     medical    treatment,
  hospitalizations and deaths from infection with this virus
  have occurred.

 In seasonal flu, certain people are at “high risk” of serious
  complications. This includes people
        65 years and older
        children younger than five years old
        pregnant women
        people of any age with certain chronic medical conditions.
 About   70 percent of people who have been
 hospitalized with this 2009 H1N1 virus have had one
 or more medical conditions previously recognized
 as placing people at “high risk” of serious seasonal flu-
 related complications. This includes pregnancy,
 diabetes, heart disease, asthma and kidney disease.
DIAGNOSIS
 To diagnose swine influenza A infection, a respiratory
 specimen would generally need to be collected within
 the first 4 to 5 days of illness (when an infected person
 is    most      likely     to    be   shedding     virus).

 However, some persons, especially children, may shed
 virus for 10 days or longer.
TREATMENT
 There are four different antiviral drugs that are
 licensed for use in the US for the treatment of
 influenza:
          Amantadine
          Rimantadine
          Oseltamivir (Tamiflu)
          Zanamivir




 While most swine influenza viruses have been
 susceptible to all four drugs, the most recent seven
 swine influenza viruses isolated from humans are
 resistant to amantadine and rimantadine
PRECAUTIONS… Hand Hygiene:
                 • Hands     should    be
                  frequently washed with
                  soap & water / alcohol
                  based     hand    rubs/
                  antiseptic hand wash.

                 • This is the single most
                  important measure to
                  reduce     the   risk    of
                  transmitting infectiontious
                  organisms from one person
                  to the other.
 COUGH ETIQUETTES:

• Cover the nose/mouth
 with a handkerchief /
 tissue  paper   when
 coughing or sneezing.

• Use tissues to contain
 respiratory   secretions
 and dispose them off in
 nearest waste receptacle
 after use.
N-95 Masks    Use an N95 respirator whenever you are in
               close contact with anyone who has or is
               suspected to have the swine flu. Close
               contact is classified as 6 feet away or less.
               The N95 mask fits snugly on the face and
               is designed to filter out particles that
               contain the virus.

              Used     respirator    masks     should
               immediately be placed in the garbage to
               avoid contact with anything else, thus
               spreading contamination.

              Never re-use an N95 respirator mask.


              After disposing of the mask, wash hands
               in warm, soapy water or use an alcohol
               based hand cleaner.
Myths about H1N1
 People can catch swine flu from eating pork
  Swine influenza viruses are not transmitted by food.
  You can not get swine influenza from eating pork or
  pork products..

 Flu is fatal
  Though the flu is contagious, it is not deadly. A doctor
  clarifies, “A lot of people are prone to the flu, but you
  will ultimately survive it. The victims would be the
  people who have low immunity”.
 Mexican food can cause swine flu
  Not at all, say the experts. Swine flu is definitely not
 caused by food supply, be it Indian or Mexican food.

 Face mask is a sure -shot way of protecting oneself
 from swine flu
  The answer could be a yes and a no at the same time.
 Although, one can use a face mask to protect oneself, it
 does     not     give      guaranteed      protection.
 Flu is dangerous just for the elderly
 This is one of the biggest myths. Anyone is susceptible, be it
 the elderly people or the younger generation, including
                            children.

 The   seasonal flu vaccine prevents swine flu
  The vaccine for seasonal flu does not protect one against
  swine flu.

 Popping     up Tamiflu prevents H1N1 influenza
  Rather, This may be lead to the formation of a resistant and
  stronger strain of virus and thus Tamiflu should only be
  used under strict supervision.
EFFECTS…
 Worst hit – Tourism Industry
 Travel advisories are being issued.
 Experts estimate that swine flu scare has cost the
 tourism industry upto 30% of its revenues.

 Imports and exports
 Pork and pork products
 Fruits

 Illegal sale of N95 masks – money making
 the price of N95 mask ranges from Rs 195- Rs 2500.
MEASURES TO BE ADOPTED
 Quarantine and isolation

 Entry screening / exit screening

 Social distancing measures

 Infection control practices

 Vaccine development

 Hospital facilities

 Laboratory requirements
The World Health Organization is
urging the planet to brace for a
second wave of the swine flu
pandemic as the heavily populated
northern     hemisphere     edges
towards the cooler season when flu
thrives.

Influenza traditionally surges to its
peak during the northern autumn
and winter. It has spread swiftly
into 177 countries, proving to be
more infectious than seasonal flu
and more durable through warmer
             months.
RECENT DEVELOPMENTS
             Swiss      pharmaceutical
             company Novartis AG has
             successfully produced a
             first batch of swine flu
             vaccine weeks ahead of
                    expectations.

             Three    Indian   pharma
             companies       -   Serum
             Institute of India (Pune),
             Bharat             Biotech
             (Hyderabad) and Panacea
             Biotech (New Delhi) - are
             working on developing the
             vaccine
Hype or Hazard?
 The hype surrounding swine flu is somewhat a mystery. For,
  hundreds of thousands of people die from normal seasonal
  flu every year.

 In India, half-a-million people die of tuberculosis every
  year, with pneumonia killing four million children annually.
  WHY IS THAT NOT HIGHLIGHTED?

 According to Google News, a whopping 24,000 articles
  have been produced on swine flu alone in the last one
  month. This even surpasses the total number of articles on
  global warming.
