With the 2012 Olympics just a few months away, a British risk analysis company has warned that the games could trigger a flu pandemic in the country.
Bath-based Maplecroft pointed out to World Health Organization (WHO) reports which rank Britain just below Singapore as having an "extreme" risk of a swine flu outbreak.
With more than 5.3 million tourists expected to attend the London Olympics this summer, Maplecroft revealed that the danger of a swine flu outbreak will be higher than normal.
"There is little pre-existing natural immunity to H5N1 infection in the human population. Should the virus improve its transmissibility, the entire human population could be vulnerable to infection", the report said.
