The deadly H1NI virus, which has killed more than 60 percent of the 600 people infected in a dozen countries since 2003, has become more lethal, according to the findings of a new study.
The study, released June 21 in Science, details the five steps taken to make the virus airborne making it easier to transfer from person-to-person. Previously, an individual would need to come into close contact with an animal or another person to contract the disease.
Researchers say two of the mutations created are already found in birds and people; natural evolution could release the remaining three. In the experiment, funded in part by the U.S. National Institutes of Health, H1N1 was made airborne and passed between ferrets. Ferrets are the mammals with the closest human reaction to flu viruses.
