According to Wikipedia
Swine influenza (also called swine flu, hog flu, pig flu and sometimes, the swine) is an infection by any one of several types of swine influenza virus. Swine influenza virus (SIV) is any strain of the influenza family of viruses that is endemic in pigs. As of 2009, the known SIV strains include influenza C and the subtypes of influenza A known as H1N1, H1N2, H3N1, H3N2, and H2N3.
Swine influenza virus is common throughout pig populations worldwide. Transmission of the virus from pigs to humans is not common and does not always lead to human influenza, often resulting only in the production of antibodies in the blood. If transmission does cause human influenza, it is called zoonotic swine flu. People with regular exposure to pigs are at increased risk of swine flu infection. The meat of an infected animal poses no risk of infection when properly cooked.
During the mid-20th century, identification of influenza subtypes became possible, allowing accurate diagnosis of transmission to humans. Since then, only 50 such transmissions have been confirmed. These strains of swine flu rarely pass from human to human. Symptoms of zoonotic swine flu in humans are similar to those of influenza and of influenza-like illness in general, namely chills, fever, sore throat, muscle pains, severe headache, coughing, weakness and general discomfort. The recommended time of isolation is about five days.
The H1N1 Swine Flu can only really be confirmed with an actual lab test. And, there isn’t a 100% tell tale sign in the form that you have novel h1n1 influenza.
• 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
• Difficulty breathing or shortness of breath
• Pain or pressure in the chest or abdomen
• Sudden dizziness
• Severe or persistent vomiting
One of the biggest problem when you have swine flu is the breathing. The most severe cases are because of that and those patients will end up intubated.
What should I do if I have swine flu?
Not all people end up in the hospital. Just think about you a flu which can end up with complication but not always the case. So you may have a flu and not even knowing is swine flu. So if your body "does not care" about the flu be careful and try not to infect anothers: family, friends or colleagues. So I would say please stay home if possible and even were a mask. You may scare your little one but it is safer that way.
I have flu. Should I panic and go to Emergency Room?
You shouldn't do that unless you have severe symptoms like high fever, difficulties breathing, vomiting. Just think about before going to emergency room with a regular flu. Hospitals are busy these days and you may get a real swine flu going there.
Should I take the vaccine?
That is debatable. Some says is not effective. Others said that wasn't properly tested especially on pregnant women and kids. So it is hard to say. Your doctor may ask you to get it. Or you got the horror news from the media and really want to have it. I would say it is up to you.
