All about Influenza A(H1N1) Virus

What is this virus?

• Influenza A(H1N1) is caused by a novel virus that resulted from the reassortment of 4 viruses from pigs, human and birds
• It is a new virus causing illness in people
• It was first detected in people in April 2009 in the United States
• This virus is spreading from person-to-person, probably in much the same way that regular seasonal influenza viruses spread
• There is no vaccine yet to protect humans from this virus
• There are existing and recommended medicines that are effective in treating these Influenza A(H1N1)
• Influenza A(H1N1) can be fatal to humans due to severe respiratory distress (pneumonia)

Why this new Influenza A(H1N1) virus is sometimes called “swine flu”?

This virus was originally referred to as “swine flu” because laboratory tests showed that many of the genes in this new virus were very similar to influenza viruses that normally occur in pigs in North America. But further study has shown that this new virus is very different from what normally circulates in North American pigs. It has two genes from flu viruses that normally circulate in pigs in Europe and Asia and avian genes and human genes. Scientists call this a “quadruple reassortant” virus.

Syptoms:

fever
chills
headache
nasal congestion or runny nose
sore throat
cough
body aches or lethargy
lack of appetite
nausea or vomiting
diarrhea
Also, like seasonal flu, severe illnesses and death has occurred as a result of illness associated with this virus.

Prevention & Treatment:

What can I do to protect myself from getting sick?

There is no vaccine available right now to protect against this new H1N1 virus. 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.
Stay home if you are sick for 7 days after your symptoms begin or until you have been symptom-free for 24 hours, whichever is longer. This is to keep from infecting others and spreading the virus further.
Follow public health advice regarding school closures, avoiding crowds and other social distancing measures.
Be prepared in case you get sick and need to stay home for a week or so; a supply of over-the-counter medicines, alcohol-based hand rubs, tissues and other related items might could be useful and help avoid the need to make trips out in public while you are sick and contagious
