Could you catch it by touching the same door knob?
Why not, if the person was sweating and had just rubbed his nose or brow?
Probably if he/she drooled on it....
If the patient had sneezed on it...
That depends on many factors, starting with the viral load on the doorknob (sweaty hand/dry hand, etc.), then whether the doorknob is exposed to direct sunlight (UV kills Ebola), and finally on how long since the victim touched the doorknob. More than 2-3 days and you are safe unless there has been ice hanging on it the whole time.
Patient in West Africa contracted it via doorknob, so yes.
Look up fomites.
He wipes his sweaty (sweat is a body fluid) forehead, then grabs the doorknob. A couple minutes later someone grabs same doorknob and a few second later rubs his nose with fingers or rubs his eye.
Yes, the infected person coughs on there hand then the virus will be active for 24 hours.. Plenty of people it can be transmitted to on a commonly touched area. The media and CDC do not address this and this is what is criminal...
