Drug resistance has been detected in patients infected with the new bird flu that has emerged in China, say doctors.

The H7N9 virus became resistant to Tamiflu in three out of 14 patients treated with antiviral drugs at Shanghai Public Health Clinical Centre.

The researchers, writing in the Lancet, said resistance emerged with "apparent ease" and was "concerning".
