Someone kissed my baby!!! Loterally in full panic

I took my baby to work to see the people I work with for years and I only let a select few people hold her. Well one of the people gave her to somebody else that have never let hold her before and Harlow was freaking out, so I went to grab her from this lady in the lady grazed her cheek with a kiss. And I literally almost had a stroke, who in the world thinks they can kiss somebody else's baby. I immediately disinfected her face but I'm still in panic mode over it I'm going to think about it for days. What do I do
