Just heard that a teenage girl who flew in from Hong Kong to San Francisco was hospitalised after a routine airport screening. Apparently she's not dangerously ill and she's recovered okay but some news released last week by the Hong Kong authorities showed that the viral sequencing had a mutation.

Experts have said it is the H274Y that could make swine flu resistant to Tamiflu. There have also been cases in Thailand, Singapore and China with reports coming in of patients developing resistance, and according to Prof Henry L Niman who founded www.recombinomics.com "These latest results signal global spread of Tamiflu resistance, which may be associated with evolutionarily fit pandemic H1N1". I suppose the worrying thing here is that the samples were collected in May and mid-June but not actually reported until this week.
