I'm in the middle, I'm more curious than concerned.
Curious that a flu virus is active during warmer months, curious that the worst results are in Mexico only, curious that a number of deaths are in the young to middle age group as opposed to the aged / infirm / very young.
For the time being, the anti-virus treatments available work (tamiflu etc) and the virus is apparently in regression. When I watched the BBC reports last night I was suddenly in mind of that brilliant virus movie from the 70's - "the Andromeda strain" where a killer virus suddenly becomes dormant.
This thing could currently go either way - like most other viruses or evolve into something far more deadly.
