Sickness at the Worlds

Any of our European correspondants have a sense of what's going on with
the illnesses? It's been variously described as a cold, a flu-like cold
and the flu. Any sense of which it is. Obviously, traveling, training
regimens and close quarters make athletes especially suceptible to
illness, but I am curious, since a flu vaccine has been available this
year and in the U.S., at least, cases are not running high yet.
