Hong Kong: Detection of human swine influenza virus resistant to Tamiflu (7/3/09)

A spokesman for the Department of Health (DH) said the department's Public Health Laboratory Services Branch (PHLSB) today (July 3) detected a strain of human swine influenza (HSI) virus which was resistant to oseltamivir (Tamiflu).


The virus was identified during PHLSB's routine sensitivity test of HSI virus to oseltamivir and zanamivir, the spokesman said.

"This is the first time Tamiflu resistance in HSI virus found in Hong Kong," he said, adding that similar cases were also reported in Denmark and possibly Japan.

"Tests showed that this strain is sensitive to zanamivir (Relenza)," he said.
