Swine Flue Basic
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
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, 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 way to keep from spreading the virus through coughing or sneezing?

Washing your hands often w
ill 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 Iget 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.

- Flu-like symptoms improve but then return with fever and worse cough
- Fever with a rash
- 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?
