Here is a CNN report:
Experts in Hong Kong said on Friday that the human H5N1 strain which surfaced in northern Vietnam this year had proved to be resistant to Tamiflu, a powerful antiviral drug which goes by the generic name, oseltamivir.
They urged drug manufacturers to make more effective versions of Relenza, another antiviral that is also known to be effective in battling the much feared H5N1. Relenza is inhaled.
