the grasp of the eucharist is the same for priest distributing on tongue vs. putting in hand. Both can be done without touching. But mistakes occur.
This is all common sense, a priest touches the host after either having his hands breathed on or his hand touching someones tongue inadvertently from someone with a virus or communicable disease, then wants to give it to you.
Over some, presumably a similar amt. of contact with hands during distribution of the host on the palm. The grasp of the host is the same in both. The amt. of unintended contact is presumably the same in both.
One involves breath(communicable transmission route CTR) and saliva contact(CTR) , the other involves hand touching(CTR). However close quarter breath and saliva are higher risk over hand transmission. READ!
The priest pouring cold water over his hands is not washing

Good luck
St. Catherine of Siena had begun to question whether her spiritual Communions had any real value compared to sacramental Communion. Suddenly she saw Christ holding two chalices. ‘In this golden chalice I put your sacramental communions. In this silver chalice I put your spiritual communions. Both chalices are quite pleasing to me.’
