Melbourne: A new Australian research has revealed that the swine flu virus that infected more than 37,000 Australians and killed 186 people in 2009 is now resistant to key flu medicine Tamiflu, raising fears a new outbreak may be difficult to fight.The research found that one in five cases of swine flu in one area in 2011 were resistant to the antiviral medicine, the Herald Sun reported.According to Dr Aeron Hurt from the World Health Organisation collaborating centre for flu research in Melbourne, the bug appears more prone than other types of flu to developing drug resistance.He suggested restricting access to anti-viral treatments to limit further resistance developing.While just 2 per cent of swine flu strains around the world are resistant to Tamiflu, the Australian research found mutations in all strains of the swine flu that suggest they might be prone to develop resistance.Tamiflu resistance develops when an individual under treatment receives the drug to control their symptoms.In most flu viruses, the changes that make the virus resistant to treatment also make it less likely to spread to others.With swine flu, this has not happened and the virus remains fit enough to spread to others, Dr Hurt said.
