The World Health Organisation says a mutation had been found in samples of the swine flu virus taken following the first two deaths from the pandemic in Norway.
“The Norwegian Institute of Public Health has informed WHO of a mutation detected in three H1N1 viruses,” the WHO said in a briefing note overnight.

“The viruses were isolated from the first two fatal cases of pandemic influenza in the country and one patient with severe illness,” it said, although it added that no further instances were found in tests.

The WHO revealed that a similar mutation had been observed in Brazil, China, Japan, Mexico, Ukraine, and the United States as early as April, but underlined that there was no evidence of more infections or more deaths as a result. — AFP
