But further research has shown that this new virus is very normal, and circulation of North America different from what pigs.

The use of any influenza virus, including the 2009 H1N1 virus infection, should cause the development of your body's immune resistance to the virus so it is not a person may be with the same influenza virus infection more than once. (However, a weak immune system may not fully develop after infection, immunity, may be easier to get the same influenza virus infection more than once.) However, this may also be a person infected with avian influenza can have a positive test result more than time in the influenza season. There are probably two reasons:

1.a person listed may be infected with a different (for example, influenza virus, and 2009 H1N1 virus, and use of conventional seasonal influenza viruses of the second or the first time. The most rapid test can not distinguish between influenza virus, the disease is responsible for. In addition, ,

2.Influenza test can occasionally give false positive and false-negative results, so that there may be a result of the test is not correct. This is more likely to occur, the diagnosis and rapid detection of bird flu.
