Me worried alot.
If the, unjustly named, "Spanish flu of 1918" (which started off in China btw, not in Spain, the same as the current H5N1) killed 50 million people, more so than WW1 or WWII(separately), we're in for deep trouble.
A spanish scientist working at Mt Sinahi in the US has revealed the genetic structure of the 1918 flu using the frozen corpse of a dead woman in Alaska. It seems both flus are extremely similar, only that 1918s has a few more mutations which enabled it to transmit itself from human-to-human.
The H5N1 has a lethal ratio of 1 in 2 persons or 55%.
Back in 1918 transports (plains, trains, buses, cars you name it) weren't as developed, nowadays ... I was in mass on Sunday and just watching how the priest gave comunion to people makes you scared, it could easily spread in churches.
It is estimated this flu If it finally mutates to human-to-human transmission could kill between 100-200 million, that's almost half the EU. When you guys talk of only 1-2 million dead you are surely not taking into account third world countries were human casualties will be massive. Relenza and Tamiflu don't cure it, there's no cure for it yet, because it still hasn't mutated to the last stage.
