What are the problems that this virus can cause to human health?
Although H5N1 can cause serious problems to human health, it is difficult to be infected with the virus and, until now, there has been no evidence that it can spread from one person to another. The problem would become most critical if the virus were found to be transmitted from human to human. In the past 100 years there were 4 A-type influenza pandemics that resulted in many deaths around the world. It is considered that these pathogenic strains are the result of a combination between the genetic material of influenza virus specific to birds and that of humans. Taking into account the recent frequent H5N1 infection situations there is a possibility of a new pandemic outbreak.
