While some scholars argue that it should be kept for research purposes genetically manipulated viruses of avian influenza in several laboratories around the world are already conducting similar experiments, reported the German magazine "Focus". Several teams working in parallel with genetically manipulated virus H7N9. Ron Fucino, one of the scientists involved in the experiments confirmed that his colleagues in several places around the world already are testing resistance to drugs.

Other attempts were allegedly in the pipeline, says Fucino who specializes Flu Medical Center "Erasmus" in Rotterdam. They will study the behavior of the virus modified so as to be easily transmitted from person to person. From mid-March in China already has at least 130 people infected with the dangerous strain H7N9.

This week leading experts called in the journal "Nature" to be carried out similar experiments in which the causative agent is modified in vitro so as to be more infectious and resistant to treatment with drugs. They hope that science will overtake both real life and will be prepared to respond to any mutations in the strain of bird flu, which has threatened a number of Asian countries.

Such an approach, however, meeting and much criticism. According to the China Center for combating infectious diseases in natural mutation of a virus can take years. In the laboratory, it happened in an instant. There is no guarantee that the actual mutations will follow artificial scientific model.

According to Ron Fucino however scientific experiments are very useful and are based on actual forecasts. Attempts would make it possible to produce more effective vaccines and scientific teams would predict risks of transmission of the virus from person to person. New form of H7N9 bird flu was confirmed in humans for the first time in March 2013 Health officials believe that spillover occurred from birds to humans. Thousands of birds were killed and live poultry markets were closed. An outcome measure, the number of new infected dropped almost to zero. In April, the WHO issued a warning that in some cases the virus can be passed from person to person. Scientists from China have joined this opinion and wrote in the British Medical Journal, the risk of bird flu is by no means
