Swine Flu Update

What is H1N1 (swine flu)?
H1N1 (referred to as “swine flu” early on) is a new influenza virus causing illness in people. This new virus was first detected in people in the United States in April 2009.
This virus is spreading from person-to-person worldwide, probably in much the same way that regular seasonal influenza viruses spread.
On June 11, 2009, the World Health Organization (WHO) signaled that a pandemic of novel H1N1 flu was underway.
Why is novel H1N1 virus sometimes called “swine flu”?
This virus was originally referred to as “swine flu” because laboratory testing showed that many of the genes in this new virus were very similar to influenza viruses that normally occur in pigs (swine) in North America.
Is H1N1 virus contagious?
CDC has determined that novel H1N1 virus is contagious and is spreading from human to human.
How does novel H1N1 virus spread?
Spread of novel H1N1 virus is thought to occur in the same way that seasonal flu spreads.
Flu viruses are spread mainly from person to person through coughing or sneezing by people with influenza.
Sometimes people may become infected by touching something – such as a surface or object – with flu viruses on it and then touching their mouth or nose.
What are the signs and symptoms of this virus in people?
The symptoms of novel H1N1 flu virus in people include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue.
A significant number of people who have been infected with this virus also have reported diarrhea and vomiting.
Severe illnesses and death has occurred as a result of illness associated with this virus.
How severe is illness associated with H1N1 flu virus?
Illness with the new H1N1 virus has ranged from mild to severe. While most people who have been sick have recovered without needing medical treatment, hospitalizations and deaths from infection with this virus have occurred.
How long can an infected person spread this virus to others?
People infected with seasonal and novel H1N1 flu shed virus and may be able to infect others from 1 day before getting sick to 5 to 7 days after. This can be longer in some people, especially children and people with weakened immune systems and in people infected with the new H1N1 virus.
What can I do to protect myself from getting sick?
There is no vaccine available right now to protect against novel H1N1 virus.
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.
Avoid touching your eyes, nose or mouth. Germs spread this way.
Try to avoid close contact with sick people.
If you are sick with flu-like illness, you stay home for 24 hours except to get medical care or for other necessities. (Your fever should be gone without the use of a fever-reducing medicine.) Keep away from others as much as possible to keep from making others sick.
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 or gray skin color
Not drinking enough fluids
Severe or persistent vomiting
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
**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
Flu-like symptoms improve but then return with fever and worse cough
Are there medicines to treat novel H1N1 infection?
Yes. CDC recommends the use of oseltamivir(Tamiflu) or zanamivir for the treatment and/or prevention of infection with novel H1N1 flu virus. Antiviral drugs are prescription medicines (pills, liquid or an inhaled powder) that fight against the flu by keeping flu viruses from reproducing in your body.
