Can someone explain why the family members who were in closed quarters with the infected lying gentleman have not shown any symptoms while this health care worker has?

Yes, I think so.

The HCWs are catching it from the protective gear. It gets heavily contaminated, it keeps the virus warm, it raises the worker's skin temperature and they sweat, and the ID₅₀ is incredibly low.

I'm more convinced than ever that transmission through the air is uncommon, that contact is the main route, and that the nature of nurses' and doctors' work PLUS the PPE gear creates a perfect situation for transmission.

That makes sense. So, the protocols need improvement. Yes, I agree with you that it is uncommon for Ebola to be transmitted by the air.
