When is it safe to kiss someone if they had sv?

[lovessquirrels]

I have 2 separate questions.

Is it safe to kiss someone who had that 7 days ago (they had no more symptoms since 7 days ago).
Would it be safe to kiss someone if that someone lives in a house where their family members had the sv 5 days ago?

Any input on this is welcome.

That second question - they are in that house every day and I fear they are in contact with leftover sv particles from when their family members were v* 5 days ago.
