Love it, I'm looking forward the next bit. Glad your're not assuming that a virus would halt changes in technology, just look what the pressures of the world wars did for tech. I'm guessing the rich would be willing to pay people to act as their proxies to avoid personal contacts. Some communities would probably try to close off altogether. I assume this virus is rather like Aids, relatively hard to catch but difficult to cure. Maybe with a long incubation time ? Hopefully you can use your medical background to explain how the health system changes in response.
