Facts
In
response to an intensifying outbreak internationally caused by a new
influenza virus of swine origin, the World Health Organization raised
the worldwide pandemic alert level to Phase
5 on April 29, 2009. A Phase 5 alert 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.”
What is Swine Influenza?
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 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.
How many swine flu viruses are there?
Like all influenza viruses, swine flu viruses change constantly. Pigs
can be infected by avian influenza and human influenza viruses as well
as swine influenza viruses. When influenza viruses from different
species infect pigs, the viruses can reassort (i.e. swap genes) and new
viruses that are a mix of swine, human and/or avian influenza viruses
can emerge. Over the years, different variations of swine flu viruses
have emerged. At this time, there are four main influenza type A virus
subtypes that have been isolated in pigs: H1N1, H1N2, H3N2, and H3N1.
However, most of the recently isolated influenza viruses from pigs have
been H1N1 viruses.
Can humans catch swine flu?
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 (e.g. children near pigs
at a fair or workers in the swine industry). In addition, there have
been documented cases of one person spreading swine flu to others. For
example, an outbreak of apparent swine flu infection in pigs in
Wisconsin in 1988 resulted in multiple human infections, and, although
no community outbreak resulted, there was antibody evidence of virus
transmission from the patient to health care workers who had close
contact with the patient.
Are there human infections with
swine flu in the U.S.?
In late March and early April 2009, cases of human infection with swine
influenza A (H1N1) viruses were first reported in Southern California
and near Guadalupe County, Texas. Other U.S. states have reported cases
of swine flu infection in humans and cases have been reported
internationally as well. An updated case count of confirmed swine flu
infections in the United States is kept at http://www.cdc.gov/swineflu/investigation.htm
CDC and local and state health agencies are working together to
investigate this situation.
What are the signs and symptoms of swine flu in people?
The symptoms of swine flu in people are similar to the symptoms of
regular human flu and include fever, cough, sore throat, body aches,
headache, chills and fatigue. Some people have reported diarrhea and
vomiting associated with swine flu. In the past, severe illness
(pneumonia and respiratory failure) and deaths have been reported with
swine flu infection in people. Like seasonal flu, swine flu may cause a
worsening of underlying chronic medical conditions.
Is this swine flu virus contagious?
This swine influenza A (H1N1) virus is contagious and is spreading from
human to human. However, at this time, it is not known how easily the
virus spreads between people.
How does swine flu spread?
Spread of this swine influenza A (H1N1) virus is thought to be happening
in the same way that seasonal flu spreads. Flu viruses are spread mainly
from person to person through coughing or sneezing of people with
influenza. Sometimes people may become infected by touching something
with flu viruses on it and then touching their mouth or nose.
Can I get swine influenza from eating or preparing pork?
No. Swine influenza viruses are not spread by food. You cannot get swine
influenza from eating pork or pork products. Eating properly handled and
cooked pork products is safe.
How can someone with the flu infect someone else?
Infected people may be able to infect others beginning 1 day before
symptoms develop and up to 7 or more days after becoming sick. That
means that you may be able to pass on the flu to someone else before you
know you are sick, as well as while you are sick.
What should I do to keep from getting
the flu?
First and most important: wash your hands. Try to stay in good general
health. Get plenty of sleep, be physically active, manage your stress,
drink plenty of fluids, and eat nutritious food. Try not touch surfaces
that may be contaminated with the flu virus. Avoid close contact with
people who are sick.
Are there medicines to treat swine flu?
Yes. Centers for Disease Control and Prevention (CDC) recommends the use
of oseltamivir or zanamivir for the treatment and/or prevention of
infection with these swine influenza viruses. Antiviral drugs are
prescription medicines (pills, liquid or an inhaler) that fight against
the flu by keeping flu viruses from reproducing in your body. If you get
sick, antiviral drugs can make your illness milder and make you feel
better faster. They may also prevent serious flu complications. For
treatment, antiviral drugs work best if started soon after getting sick
(within 2 days of symptoms).
How long can an infected person spread swine flu to others?
People with swine influenza virus infection should be considered
potentially contagious as long as they are symptomatic and possible for
up to 7 days following illness onset. Children, especially younger
children, might potentially be contagious for longer periods.
What surfaces are most likely to be sources of contamination?
Germs can be spread when a person touches something that is contaminated
with germs and then touches his or her eyes, nose, or mouth. Droplets
from a cough or sneeze of an infected person move through the air. Germs
can be spread when a person touches respiratory droplets from another
person on a surface like a desk and then touches their own eyes, mouth
or nose before washing their hands.
How long can viruses live outside the body?
We know that some viruses and bacteria can live 2 hours or longer on
surfaces like cafeteria tables, doorknobs, and desks. Frequent
handwashing will help you reduce the chance of getting contamination
from these common surfaces.

What can I do to protect myself from getting sick?
There is no vaccine available right now to protect against swine flu.
There are everyday actions that can help prevent the spread of germs
that cause respiratory illnesses like influenza. Take these everyday
steps to protect your health:
-
Cover your nose and mouth with a tissue when you cough or sneeze.
Throw the tissue in the trash after you use it.
-
Wash your hands often with soap and water, especially after you
cough or sneeze. Alcohol-based hand cleaners are also effective.
-
Avoid touching your eyes, nose or mouth. Germs spread this way.
-
Try to avoid close contact with sick people.
-
If you get sick with influenza, it is recommended that you stay
home from work or school and limit contact with others to keep from
infecting them.
How do I care for an ill person at home?
-
Separate the ill person from others, at least 1 meter in distance
from others.
-
Cover your mouth and nose when caring for the ill person. Either
commercial or homemade materials are fine, as long as they are
disposed of or cleaned properly after use.
-
Wash your hands with soap and water thoroughly after each contact
with the ill person.
-
Improve the air flow where the ill person stays. Use doors and
windows to take advantage of breezes.
-
Keep the environment clean with readily available household
cleaning agents.
If you are living in a country where there are infections
follow additional advice from your national and local health
authorities.
What should I do if I think I have the
illness?
If you feel unwell, have high fever, cough or sore throat:
-
Stay at home and keep away from work, school or crowds.
-
Rest and take plenty of fluids.
-
Cover your mouth and nose with disposable tissues when coughing
and sneezing, and dispose of the used tissues properly.
-
Wash your hands with soap and water often and thoroughly,
especially after coughing or sneezing.
-
Inform family and friends about your illness and try to avoid
contact with people.
What should I do if I get sick and need
medical attention?
If you live in areas where swine influenza cases have been identified
and become ill with influenza-like symptoms, including fever, body
aches, runny nose, sore throat, nausea, or vomiting or diarrhea,
-
Contact your doctor or healthcare provider before travelling to a
health facility, and report your symptoms. Explain why you think you
have influenza A(H1N1) (for example, if you have recently travelled
to a country where there is an outbreak in humans). Follow the
advice given to you.
-
If it is not possible to contact your healthcare provider in
advance, communicate your suspicion of infection as soon as you
arrive at the facility.
-
Cover your nose and mouth during travel.
What is the best way to keep from spreading the virus through
coughing or sneezing?
If you are sick, limit your contact with other people as much as
possible. Do not go to work or school if ill. Cover your mouth and nose
with a tissue when coughing or sneezing. It may prevent those around you
from getting sick. Put your used tissue in the waste basket. Cover your
cough or sneeze if you do not have a tissue. Then, clean your hands, and
do so every time you cough or sneeze.
What is the best technique for washing my hands to avoid
getting the flu?
Washing your hands often will help protect you from germs. Wash with
soap and water or clean with alcohol-based hand cleaner. We recommend
that when you wash your hands -- with soap and warm water -- that you
wash for 15 to 20 seconds. When soap and water are not available,
alcohol-based disposable hand wipes or gel sanitizers may be used. You
can find them in most supermarkets and drugstores. If using gel, rub
your hands until the gel is dry. The gel doesn't need water to work; the
alcohol in it kills the germs on your hands.
How serious is swine flu infection?
Like seasonal flu, swine flu in humans can vary in severity from mild to
severe. Between 2005 until January 2009, 12 human cases of swine flu
were detected in the U.S. with no deaths occurring. However, swine flu
infection can be serious. In September 1988, a previously healthy
32-year-old pregnant woman in Wisconsin was hospitalized for pneumonia
after being infected with swine flu and died 8 days later. A swine flu
outbreak in Fort Dix, New Jersey occurred in 1976 that caused more than
200 cases with serious illness in several people and one death.
