Background
Swine Influenza (H1N1)
7/21/2015
First
Remember, Keep Things in Perspective:
• Influenza is a normal part of our lives but is always
potentially dangerous, especially to the young, the
elderly, or people with compromised immune systems
• The more common Influenza (the flu) is a contagious
respiratory illness caused by influenza viruses. It can
cause mild to severe illness, and at times can lead to
death
• There are currently three strains of influenza circulating
in NYS (two seasonal)
• Every year in the United States, on average 5% to 20%
of the population gets the flu
• This outbreak, so far, appears to be a mild strain

What is Swine Influenza?
• Swine Influenza (formally H1N1) 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 influenza viruses
may circulate among swine throughout the year,
but most outbreaks occur during the late fall and
winter months similar to outbreaks in humans.
• The classical swine flu virus (an influenza type A
H1N1 virus) was first isolated from a pig in 1930.

• The 2009 flu outbreak in humans is due to a new
strain of influenza
• The origins of this new strain are unknown, and
the World Organization for Animal Health (OIE)
reports that this strain has not been isolated in
swine
• It passes with apparent ease from human to
human, an ability attributed to an as-yet
unidentified mutation
• The strain in most cases causes only mild
symptoms and the infected person makes a full
recovery without requiring medical attention and
without the use of antiviral medicines
• The World Health Organization has stated that
symptoms may even be less severe than
seasonal influenza symptoms.

How serious is it?
• At this time it appears this strain is a mild
virus
• It may mutate eventually and become
more serious
• NYSDOH recommends treating this like
seasonal influenza

Will my regular flu shot help?
• No, this is a different strain and influenza
vaccine will not help
• However, there are currently two seasonal
strains of influenza circulating and
NYSDOH is recommending, to help avoid
confusion, that you receive a vaccination
for those if you have not yet been
immunized

How do you catch Swine Flu?
• The same way you would catch any other
cold or flu virus – transmission appears to
be same as seasonal flu
– When an infected person coughs or sneezes
around another person
– Touching something with the flu virus on it
then touching your mouth, nose, or eyes.
– An infected person can pass the virus to
another before any symptoms develop and
after symptoms subside

Symptoms of Swine Flu
• Very similar to regular flu
• Typically happens after regular flu season is
over
• Upper respiratory symptoms, may have
nausea, vomiting, diarrhea
• Some incidents of sudden dizziness
• If feverish or have other flu-like symptoms,
call your doctor or occupational health nurse!
Try to avoid the emergency room or doctor’s
office.

Can people catch swine flu from
eating pork?
• No. Swine influenza viruses are not transmitted
by food.
• You can not get swine influenza from eating pork
or pork products.
• Eating properly handled and cooked pork and
pork products is safe.
• Cooking pork to an internal temperature of
160°F kills the swine flu virus as it does other
bacteria and viruses

Primary Prevention
Policies Needed by Providers
• Screening for symptoms
• Employees should not travel or work if ill:
temp greater than 100 degrees combined
with recent onset of cough, sore throat,
nasal congestion
• Have policies for primary prevention
methods
• Sick leave policies so ill employees can
stay home

Preventing Spread of H1N1 Flu
•Hand washing with soap and water or
alcohol-based hand cleaner
•Avoid touching your mouth, eyes and
nose as much as possible
•Use cough etiquette
•If you are sick, stay home and avoid
close contact to others
•Avoid crowds

What about travelers returning
from Mexico?
• Monitor for signs of flu
• Incubation period is 1-7 days
• Treat accordingly

What Does Pandemic Mean?
• A pandemic is a global disease outbreak.
• An influenza pandemic occurs when a new
influenza A virus emerges for which there
is little or no immunity in the human
population, begins to cause serious illness
and then spreads easily person-to-person
worldwide.
• We are currently in Pandemic Phase 5

Home Care Association of NYS
14
Pandemic Phases
Phase 5 is characterized by human-to-human spread of the virus
into at least two countries in one WHO region. While most
countries will not be affected at this stage, the declaration of
Phase 5 is a strong signal that a pandemic is imminent and that
the time to finalize the organization, communication, and
implementation of the planned mitigation measures is short

How long can viruses live on
surfaces?
• Some viruses and bacteria can live two
hours or longer on surfaces such as ATMs,
doorknobs, money, computer keyboards,
etc.
• Find out about infection control measures
for laptops, bags, or anything you carry
with you.
• Keep your waterless hand sanitizer with
you at all times.

How long are people
contagious?
• 7 days after symptoms start
• Children are considered to be contagious
longer than adults – possibly up to 14 days
• Tamiflu can reduce symptoms – refer to
NYSDOH guidance/advisory

• In presence of Febrile Respiratory illness
only
