"What's most worrying is that this new virus is affecting young, healthy
adults - the same group affected by the pandemic flu virus of 1918.
Those usually vulnerable to flu, the elderly and the very young, were at
less risk then and, it appears, now.
According to Dr Hay this is key in trying to assess the likelihood of
this virus causing a pandemic: "That was the unusual feature about 1918,
it was the healthy young adults that suffered most... and I think
everybody understands the implications," he said.

He described the situation in Mexico as "totally different" from the
intermittent cases of H5N1 bird flu among people, because it appears to
be spreading so fast. Sporadic bird flu infections in people have
alerted the world to the possibility of a pandemic, but Dr Hay said this
H1 swine flu virus is "already worse than H5", in terms of "the number
of cases, the number of deaths and the locality of the area
affected...This isn't sporadic, this is human"."
