24 mutated, Tamiflu-resistant viruses found in the UK

In a statement Thursday, British officials said they have found 24 swine flu viruses with a mutation associated with Tamiflu resistance. Contrary to WHO guidance, Britain gives out Tamiflu liberally, and does not require a doctor's advice to get the antiviral. Critics warn that could speed up the development of resistant viruses.

More details

Since the beginning of
the pandemic a total of 4,002
pandemic influenza viruses have
been analysed for the marker
commonly associated with
resistance to oseltamivir in
seasonal influenza (H275Y); a
total of 24 samples have been
found to carry this mutation in the
UK. Of these 4,002 viruses, 293
have been fully tested for
susceptibility; 3 of the 24 viruses carrying the H275Y mutation have been confirmed to be phenotypically
resistant to oseltamivir whilst retaining sensitivity to zanamivir. Information on medical history was available
for 17 cases, all of whom had an underlying medical condition: 14 were immunosuppressed and three had
chronic respiratory or neurological illnesses. Probable person to person transmission has occurred in an
outbreak in a hospital ward.
