Antiviral-resistant H1N1 virus in Australia didn't spread farAn oseltamivir-resistant 2009 H1N1 virus that spread in one Australian community in 2011 apparently did not escape to a nearby large city, according to a report published in Eurosurveillance yesterday. Researchers previously reported the community spread of a resistant 2009 H1N1 virus in the Newcastle, Australia, area from June through August of 2011, the report notes.
