Ebola is spread via contact with bodily fluids. So does HIV and hepatitis.
There are (for us Americans), over 1.2 million people in our country that are HIV positive. There are about 3.2 million with Hepatitis-C. There are maybe two or three (that's just a 2 or 3. Not million. Count it on one hand please.) with Ebola, or at least less than ten confirmed cases. If we're generous, we can add another 20 unconfirmed.
Have you suddenly contracted HIV yet? What about Hepatitis-C? No? Well you probably won't suddenly contract Ebola. As it turns out Ebola is actually much LESS contagious than the other two. It's hard to contract, even if you are exposed, as long as you follow basic sanitary practice like washing your hands.
BUT WHAT IF IT MUTATES TO BECOME AIRBORNE?!!?
Yeah no, highly unlikely. Viruses mutate almost constantly. All viruses do that. How many of them have suddenly become airborne just to fuck with us? Is HIV airborne, despite having a far greater prevelence? What about Hep-C again? No, huh? So what makes Ebola special?
Maybe this would be a good place for Arista to chime in, since she's actually a Biologist. Maybe not a virologist, but closer than me nonetheless.
How likely is it that Ebola will suddenly mutate to become the next airborne scare? Because, to be honest... that's extremely rare from what I understand.
