A(H1N1): Two Tamiflu-resistant flu cases in US

The Seattle health department said on Friday that two immuno-suppressed patients being treated for A (H1N) flu had been identified as resistant to Tamiflu, China’s Xinhua news agency reported.

One case involved a male teenager with leukaemia who received a stem cell transplant in early May, according to local health experts. While recovering in hospital in a single room he contracted A(H1N1) flu, they said, adding the boy has recovered.

The second case involved a woman in her 40s, who also has leukaemia and had a stem cell transplant late last year, the health experts said. That woman remains in hospital and is being treated with an intravenous form of the only other flu drug available, Relenza, and another antiviral drug, ribavirin, they disclosed, saying the two patients have no links to each other.

Local health officials also said that there is no evidence indicating that people who came in contact with the two patients became infected with a Tamiflu-resistant virus.
