Provide a set of disposable gloves, caps, goggles to care givers instead of teaching how to use plastic bags!
The story of nursing student saving her family wrapped herself in plastic bags was very impressive. Another research says about 70% of Ebola victims are women, obviously many of whom got infected while taking care of their family.
The most urgent thing to be done is to provide the care-givers sanitation equipment to protect themselves. I suggest we make a set of glove, goggle, head cap, ear cap, foot cap in a material of plastic bag. I think this can be of minimum costs but of prompt impact.
