It was an interesting article.
When I read articles like that I think about how it is seldom the thing you are expecting that becomes the emergency.
We know about Ebola and Marsburg and have at least some idea of how to deal with that. We have learned a bit about Influenza, Bird Flue, West Nile and SARS, with SARS being a bit of a scramble.
We are just starting to find out about multiple drug resistant bacteria (Staph. aureus, Tuberculosis,and other superbugs)
Yet we are always well prepared to fight the battles we already won, so even if many of our old diseases are showing a resurgence in poorer parts of the world we at least have knowledge about them.
So I am a bit concerned that the next threat will be something we will never expect in a million years but will seem obvious after it happens.
If we could prepare for everything then emergencies would never happen.
To bad it is not possible to be prepared for everything that might happen.
