Meh, can't live forever!
100 people dead out of 6 billion in the span of a few weeks...I like my odds! Really though, it is just the flu of a new strain. We get new strains of flu every year. Each is a little stronger than the last (as the germs adapt to our immune systems which we toughen through new antibiotics). Like anything else, wash your hands! Sanitize your space! be careful! Common sense things. Last time I was in Mexico, I noticed that in most of the places I went, people didn't exactly have a firm grasp of sanitation or the like. In places like that, even the simplist flu can be deadly, not to mention an advanced strain. All the pictures I saw in the paper of people walking around in masks were from...guess where...Mexico!
I think we'll be ok.
