2. Introduction
 Swine influenza has many names like swine flu, pig
influenza, pig flu and hog flu.
 Swine flu is an infection in pigs which is caused by any
one of the swine influenza viruses.
 This infection got the name Swine flu because the first
outbreak was seen mainly in people associated with
pigs.

3. Factors about Swine Flu
 Swine flu though tends to transmit among pigs but
sometimes it can cross the barrier of species and enter
humans.
 In pigs the infection gets transmitted mostly through
direct contact between the infected pig and the
uninfected one.
 The direct contact occurs mainly during transportation
of animals in vehicles.

4.  In some cases people carry out intensive farming
where too many pigs are raised up in a small place.
 Dried mucus or touching of nose by pigs can be the
common cause of transmission.
 Wild boars can also spread the disease in farms.

5. Different Swine Flu strains
 Swine influenza virus (SIV) infection is prevalent in
pigs.
 Its infection can also cause death in pigs. It lasts for
about 2 weeks in pigs that manage to survive.
 The SIV strains are influenza C and subtypes of
influenza A which include H1N1, H1N2, H2N1,
H3N1, H3N2 and H2N3.
 In humans the infection is caused by H1N1 type.

6.  The latest swine flu virus causing swine flu is the
influenza A subtype H3N2v which is also termed as
H3N2v.
 The outbreak of this infection was in 2011.
 “v” denotes that the virus is a variant which can cause
infection in pigs but now it is infecting humans also.

7. Transmission in humans
 The transmission of swine flu virus from pigs to
humans is not commonly seen and it will not always
cause human flu.
 It can lead to formation of antibodies in the blood.
 The transmission which does not cause human flu is
known as zoonotic swine flu.
 People who are in constant contact with pigs like
farmers, pork processors are at the greater risk of
swine flu.

8.  It is transmitted amongst humans by sneezing, coughing,
inhalation as the droplets contain virus of infected people.
 The disease does not spread by consuming cooked pork
products.

9. Symptoms
 Temperature (fever)
 Cough
 Runny or stuffy nose
 Body aches
 Headache
 Chills
 Fatigue (unusual tiredness)
 Sore throat
 Diarrhoea, nausea and vomiting

10. Other causes for swine flu
 Pneumonia which can leading to sepsis
 High fever causing neurological issues
 Dehydration due to excessive vomiting and diarrhoea
 Kidney failure
 Electrolyte imbalance

11. Tests for swine flu
 The doctor or nurse takes a swab of the throat or nose
of the infected person for taking the sample.
 Further analysis of the swab is done in laboratory using
several genetic and laboratory methods for
identification of the specific virus.
 These tests are done to check whether the patient is
infected with influenza A or B virus.
 The test result is either positive or negative.
 In case it is positive (type A or B) there are other
possibilities also. If the test done is positive for type B
it cannot be said instantly that the infection is swine
flu.

12. Preventive Measures against Swine flu
 Farmers, pork dealers and veterinarians who are in
contact with pigs have high risk of getting infected.
They should wear masks on faces in farms especially
while dealing with infected pigs.
 Avoid smoking when in contact with infected pigs. It
can easily transmit the virus.
 Wear gloves while working in farms and use
disposable gloves if possible.
 Exercise regularly.
 Avoid stress in life.

13.  It is good to wash your hands with soap regularly.
Most of the infections are transmitted through our
hands.
 You can do some stress management programs if you
are under constant work pressure.
 Fluid intake should be adequate.
 Drink plenty of water in a day.

14. precautions for preventing its spread
amongst others
 Take a break from office or school.
 Always cover your nose and mouth while coughing,
sneezing with a handkerchief or tissue.
 Ensure that used tissues are not kept anywhere. They
may spread infection. Put them in dustbins.
 Make it a point to wash your hands, legs and face
regularly.
 Stay away from children. They are more prone to
infection.
 Follow doctor’s instructions and take proper
medication.

15. Treatment for Swine Flu
 If a person gets infected by swine flu virus, he or she
can be treated by antiviral drugs. These drugs reduce
the illness and helps in fast recovery of the patients.
 The drugs can also help in preventing other
complications due to flu.
 Patients who are hospitalised can be treated with these
medicines but under supervision.
 Sometimes special care such as ventilation and
supportive treatment for secondary infections like
pneumonia is required in patients with severe
infection.

16. Swine Flu Vaccines
 Apart from shot, flu vaccine is also
given in the form of spray-LAIV.
 However, it can cause very mild to
moderate respiratory side effects such
as headache, cough, runny nose and
sore throat.
 In case of adverse effects, you need to
consult your health-care professional
who can help you with proper
treatment.

17. Swine Flu Risks for Pregnant Women
 Pregnant women are at higher risk of
getting swine flu.
 According to health experts, as the baby
begins to develop and grow inside the
womb of a mother, it puts pressure on
the lung function and breathing of the
mother thereby increasing her chances of
acquiring secondary infections like
pneumonia.

18.  In the past few years there have been many cases of
maternal deaths due to swine flu, especially during
the third trimester.
