Swine Flu
- Questions and Answers Sheet
What is swine flu?
Swine Influenza (swine flu) is a respiratory disease of pigs caused by type
A influenza viruses that causes regular outbreaks in pigs. People do not normally
get swine flu, but human infections can and do happen. Swine flu viruses have
been reported to spread from person-to-person, but in the past, this transmission
was limited and not sustained beyond three people.
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 San Antonio,
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.
Is this swine flu virus contagious?
CDC has determined that this swine influenza A (H1N1) virus is contagious
and is spreading from human to human. However, at this time, it not known
how easily the virus spreads between people.
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.
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.
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. 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 hand washing 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, CDC recommends that you stay home from work or school and limit contact with others to keep from infecting them.
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.
What should I do if I get sick?
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, you may want to contact
their health care provider, particularly if you are worried about your symptoms.
Your health care provider will determine whether influenza testing or treatment
is needed.
If you are sick, you should stay home and avoid contact with other people as much as possible to keep from spreading your illness to others.
If you become ill and experience any of the following warning signs, seek emergency medical care.
In children emergency warning signs that need urgent medical attention include:
Fast breathing or trouble breathing
Bluish skin color
Not drinking enough fluids
Not waking up or not interacting
Being so irritable that the child does not want to be held
Flu-like symptoms improve but then return with fever and worse cough
Fever with a rash
In adults, emergency warning signs that need urgent medical attention include:
Difficulty breathing or shortness of breath
Pain or pressure in the chest or abdomen
Sudden dizziness
Confusion
Severe or persistent vomiting.
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.
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.
