The Center for Health Protection of Hong Kong said on Friday it has received report on the first local case of Tamiflu-resistant influenza A/H1N1, Xinhua reported.
It was the seventh case of Tamiflu-resistant influenza A/H1N1 reported to the World Health Organization.
The Center for Health Protection said the case involved a 40- year-old woman who started taking Tamiflu on July 15 after 21 people at the home fell ill the day before. She developed a fever, cough and sore throat on July 21 and was sent to a local hospital. She was confirmed to be infected with influenza A/H1N1 and later recovered.
Laboratory tests available on Friday showed that her virus sample was resistant to Tamiflu. Thomas Tsang, controller of the center, said there was no sign of such cases spreading in Hong Kong.
