From where I'm standing, seeing a WG will still carry the risks of:
Incall: other punters will have been and gone, and left their fingerprints on doorhandles, hard surfaces, bathroom taps etc.
Likewise, their saliva/mucus droplets will be on all surfaces.
They'll have had intimate contact with the WG, even if no kissing.
I think it's safe to say that just being with a WG in her own environment, means that if she has Covid-19, you will be exposed to it, and in a big amount (the viral load thing).
For Outcall: some of the above won't apply, but she'll probably be coming from her own place where all of the above do apply.
Even if new rules allow it at some future point, if CV is still around to any degree, going on a punt will effectively mean you come into intimate contact with all the other punters that WG has seen in the previous week or so, even if she doesn't display any symptoms.
