The Centre for Health Protection has detected the first local human swine flu case resistant to Tamiflu, involving a 40-year-old woman resident of a home for the disabled in Eastern District.
Centre Controller Dr Thomas Tsang said today she started taking Tamiflu on July 15 after 21 people at the home fell ill the day before. She came down with a fever, cough and sore throat on July 21 and was sent to Eastern District Hospital. She was confirmed to be infected with swine flu and later recovered.
Laboratory tests available today showed her virus sample was resistant to Tamiflu - the only one among the 21 cases at the home.
Describing the woman's case as an isolated one, Dr Tsang said there is no sign of Tamiflu-resistant cases spreading at the home.
