The decision to publish the controversial paper explaining the way to spread the lethal H5N1 bird flu could help attract experts from unrelated fields, who might eventually make important contributions, Dr. Anthony S. Fauci said.

Around six months ago, a scientific advisory board had recommended the controversial papers’ most potentially dangerous data to be censored, but the paper, from the scientists at Netherlands-based Erasmus Medical Center, was published last Thursday.

Dr. Fauci, the director of the National Institute for Allergy & Infectious Diseases, acknowledged that the risk involved in the publication of the paper, but argued that the benefits would be greater than the risks.

Supporting the publication of the paper, he said, “Being in the free and open literature makes it easier to get a lot of the good guys involved than the risk of getting the rare bad guy involved.”

The controversial paper identified five mutations that are necessary to make the bird flu virus spread more easily among ferrets that catch the same infections that human beings do.

Records claim that H5N1 virus has infected only around six hundred humans over the past decade as it spread among wild and poultry birds, but more than half of the infected lost their lives.
