The flu virus could be mutating in Australia, New Zealand and Singapore
The virus called H1N1 flu could be mutating into a form slightly different from the previous year which has begun to prevail in Australia, New Zealand and Singapore, according to a report by the Center for Reference and Research on Influenza Melbourne (Australia), member of the World Health Organization (WHO).

As explained by this center spokesman Ian Barr in the publication 'on line' 'Eurosurveillance', will require more research to know whether the new strain is more capable of killing or whether the current vaccine can protect against it.
However, "this may represent the beginning of minor genetic variation of influenza A virus that may require an update of the vaccine ahead of schedule." In this regard, he added that it is possible both to be more deadly as it can infect people and vaccinated.
Flu viruses mutate constantly, which is why people need a flu shot each year. The virus called influenza A has been very stable since it appeared in March 2009, since when he has not suffered almost no mutation.
Scientists around the world have observed this strain if new mutations appeared, because although the H1N1 has proved not to be especially deadly, got spread around the world in weeks and kill more children and young adults than the average of other strains.
"The virus has changed little since its inception in 2009. However, this report describes various genetic changes in influenza A virus," Barr said in reference to his status report, available on the web 'http:/ / www.eurosurveillance.org '.
"These variants were first detected in Singapore earlier this year and have been extended later by Australia and New Zealand," says this expert, who acknowledges that the changes are not significant yet, but already have been cases of people vaccinated have been infected and even some deaths.
Some 18,450 people died worldwide from influenza A, according to WHO, including pregnant women and young people. However, the WHO says it will still have to spend a year after the end of the pandemic to determine the true number of deaths could be much higher.
Seasonal influenza kills about 500,000 people each year, 90 percent of them elderly, according to WHO. The 1957 pandemic killed two million people and the last pandemic in 1968, about one million
