AIDS, Ebola, and Hep C is and does pose a threat to the general public, and to say they are not airborne is misleading because if they weren't why the total encapsulation suits worn by the victim and the health workers. Care to sit next to someone with Ebola who's coughing and hacking all over the place next to you? AIDS is a bit different as its mostly spread by sexual contact, mostly. Ebola is direct contact, meaning hands, feet, spittle, splashes, rags soaked in fluids, toilets, handles, etc... Think of the number of health care workers and providers and first responders there are in this country alone, that includes all police, guards, highway patrol, jail guards and all workers there, CERT teams, firefighters, paramedics, RN's, LPN's, all workers in all hospitals, full time, part time, auxillary, volunteers, all their families and all the people they come in contact with, that's not even including any secondary medical workers that include dentists, therapists, social workers, etc.... Still think it doesn't pose a threat to the general public just because its only located in a small strip of land in another continent? Well, the disease may be locally to there but we now have victims infected right here in the U.S. If you think that all the people I listed above are NOT part of the general public then you must live in a very isolated area.
