The key challenge is to prevent contact between the patient and the healthcare worker. Everything I've seen involves sealing the healthcare worker in protective gear that is single use. What if we seal the patient instead?
The alien like suits will likely be a necessity unless and until a good vaccine is available. I think if it were me, I'd rather see humans directly even if through a bubble. Either way, we need people on the ground who can keep patients calm and explain what is happening. Someone wrote about ebola survivors who are now, I think, immune. They would be perfect for such a job.
