Are you telling me that no testing was done of the sores that he had present?
I would say that while acquiring herpes from spit is biologically possible, I think it would be incredibly low risk, especially in the situation that you described. If I were in your situation, I would simply observe the little one for any apparent sores and take her in if there were some present. Honestly, we don’t even know if your son has oral herpes because no testing was done at least you didn’t mention any.
