New reports have been released that H1N1 flu strain may have mutated as a new form of the virus has been active in Australia, New Zealand and Singapore. More research is needed, however, to ascertain whether or not the new flu mutation will be more deadly and if the current vaccine will fully protect against it. Flu viruses mutate all the time, but the H1N1 strain has not shown any changes since it first emerged in 2009. While H1N1 was not especially deadly, it did spread quickly around the world, and was declared a pandemic by the World Health Organization (WHO). It was also responsible for more child and young adult deaths than regular flu usually is. The WHO declared the pandemic to be over in August of this year, but H1N1 has now become the main seasonal flu strain almost everywhere but South Africa. Ian Barr of the World Health Organization Collaborating Center for Reference and Research on Influenza in Melbourne, Australia said that his team wrote a report about N1H1 last year and reported several changes in the virus even back then. These changes were noticed in Singapore in early 2010, and while they are not particularly dangerous just yet, several people who have received the vaccine have been infected with the new strain.
