For the first time, humans have been exposed to this form of influenza and hence there is no specific medicine for this. This is the reason that has made the 2009 swine flu so dangerous. At present, there are no preventative drugs which can be taken so as to prevent it. Hence, children, elderly people and people who have a weak immune system should be cautious so that they do not get attacked by the flu. Swine flu initially originated from Mexico and later the virus spread all around the world. Cases of swine flu are starting to get visible in US. It has now been specifically renamed as H1N1 influenza or H1N1 flu to avoid people thinking that it has some connection to pigs.

People 65 years old and above, children younger than five years, pregnant women and people with weak immune system are at higher risk of getting affected with this swine flu virus. The symptoms of swine flu are similar to normal seasonal flu, so to make difference between them is a tough task.

The common symptoms are high fever and chills in the beginning, severe fatigue and body aches. Other symptoms like cough, cold, sore throat, difficulty in breathing, headache, weakness and general discomfort are also present. Some people experience diarrhoea, nausea and vomiting.

Swine flu is contagious. So you should stay home unless you are going to the hospital for treatment. It is important that you consult your physician for swine flu tests if you notice any of these symptoms. If it is diagnosed in an early stage, there is a good chance of making a quick recovery.

To prevent catching the virus, cover your nose with a mask. If you have symptoms of cold or flu, cover your nose and mouth with a tissue when you cough and sneeze to prevent other people from getting infected. Wash your hands often with antibacterial soap. Avoid touching your nose, eyes or mouth since viruses spread that way fast. Avoid going to school, office or anywhere outside.
