Fewer people have died from a new flu strain in Mexico than previously thought, it has emerged.Mexico has cut its death toll from 176 to just over 100; suggesting the infection rate is slowing. But Britain is not about to lower its alert level after reporting a second case of human-to-human contamination in a man who has been quarantined at his home in south Gloucestershire. Barry Greatorex, 43, said: “I was in our office up in the east Midlands last week, had a meeting with a person who’d recently returned from Mexico, and that seems to be where I’ve contracted it. “ Elsewhere in Europe, Italy has confirmed its first case in a man who has just returned from Mexico. He is now said to have recovered; but medical experts say there’s still a danger of more human-to-human infections. Jorg Hacker of the Robert Koch-Institut said: “We can’t exclude the possibility of a pandemic even if the figures and the development rate at the moment don’t suggest it…. We’re learning slowly how the virus behaves, how it acts on human beings, how it acts on the immune system, all this needs time, but we’re learning more every day.” Meanwhile, Mexico, the epicentre of the outbreak, now has 443 confirmed cases including 16 deaths., according the the World Health Organisation.
