Human Swine Influenza is a combination of swine flu, avian flu and human flu virus, but it has always been a mystery that no one can answer how this virus is form.
Australian plant virologist Gibbs (Adrian Gibbs) believed that the swine flu was not from nature, but the development of human vaccines in the laboratory, which accidentally allow a virus to escape and affected by the human.
WHO did not agree the theory of the 75-year-old Gibbs, after he analysis the swine influenza gene of Mexico and the United States, he found that the evolution of swine influenza viruses is much faster than the general body of the influenza virus in pigs, so it should not like spread out by pig. In his view, the virus may be from another host, such as birds or fish, who spent a period of time evolution; or researchers in the laboratory to develop vaccines using an egg, the birth of the virus in eggs, was escape from the laboratory and then proliferate in the community.
Gibbs said: "The virus may be caused by human error, the sooner we know the virus come from, the more security." He had written the report of the findings, but not published. However, he conceded that it is not enough evidence to show swine influenza virus is transmitted by the laboratory, "escaped" over the weekend, therefore he reported the case to WHO, the WHO would like to investigate.
WHO had contacted the world's human and animal influenza laboratories, research Gibbs arguments are true. Acting Assistant Director-General of WHO Keiji Fukuda said that at present all the evidence do not support the theory of Gibbs. U.S. Centers for Disease Control and Prevention Department of influenza tester Dramix (Nancy Cox), did not agree with Gibbs because he did not got South American and African swine flu virus samples and the new type of swine influenza virus was evolutes in these two countries, and also "no evidence that the virus originated from an egg."
