Actually you don’t need to be a scholar at all you just need a tiny bit of common sense.So you don't have to be a scholar to understand that kissing is the most likely way to transmit the virus.
So I understand that those who don't want to kiss currently have the best defeat for not doing that.
If you are going to spend 90-120 minutes up close and personal with an infected person you will also be infected whether you kiss her or not.
I very much doubt that all those elderly people in nursing homes were ramming their tongues down each other’s throats and look at the devastation and death that took place.
Perhaps you should rethink whether or not kissing makes any difference whatsoever.
If you want to be safe stay at home but don’t let yourself get into a false sense of safety thinking you will be safer if you don’t kiss.
