am i just being over protective or should i really be worried?

so i took my one month old with me to visit some friends. i had no idea one of them was sick until just before i left. she said she had a fever last week and now she is just in the final stages of getting over the cold. should i be extremely worried? she held him and she touched some of his things in my diaper bag. i’m feeling very concerned, but i am a first time mom and i get anxious about a lot of things that there is no need to be anxious about.
