A alternative adaptation to this is to stay indoors. A lot. Imagine people working and socializing in virtual environments only. Sharing physical space or having physical contact with people might soon become something limited to family or sexual partners, and I would argue we are already moving in that direction. Even causal sex, one of the few ways in which we have more interpersonal contact with different people than we used to, may be on the way out if virtual sex or sex bots (sex with a human through a robot avatar might be a superior experience soon) become good enough that only romantics bother with the "natural" kind.

Taking a few additional precautions to systematically reduce the possibility of infection with food and other deliveries one could get a high level of safety. Oceans, moutains and deserts used to be barriers to disease, might our front door prove a suitable replacement? If you live with only a few people, you can make the entire home one big bubble.

This could eventually transition to bodies being sustained by artificial means and people spending all their time in virtual space or incarnated in real life robotic avatars. Might not sound much better than total constant surveillance, but consider, we may actually be able to have more privacy preserved in society that moves first in this direction than if we first eliminate privacy and then transition to a mostly virtual life.
