remember OP, ebola is only transferred through stuff piss and blood
unless some dude goes around stuffting on people for no reason then dont be worried
they'll just bleed to death and all will be safe again
It's more than waste and blood. Saliva, semen and sweat can also transmit Ebola. Inhaling someone's breath, being sneezed or coughed on, brushing past somebody with the disease followed by rubbing your nose will score you Ebola. It's said to have upwards of a 3 week incubation period in which you can transmit the virus without even knowing you have it.
The virus is being contained with airborne precautions, but I'm not very convinced. All it takes is one mistake.
