Scared I didn’t protect my baby

My 1 year old son, husband and I went on a vacation with my husband’s friend. We shared hotel rooms during our trip. I found out that the friend slept with a prostitute in the past and now I’m concerned for my son’s safety. When we were on vacation, he left his suitcase open and the baby pounced on the inside of his suitcase..on the side where u can put things like toiletries etc. so on the top it was transparent and I saw a pack of razor blades but they were facing down and covered and I don’t think baby touched that but I’m worried what was underneath cause i couldn’t see from the fabric. He didn’t act hurt when he pounced on it with his hands but I’m still having bad anxiety. What can I do to stop feeling so anxious about this? My concern is what if he pricked himself on something. Should I get him tested and for what? If I asked such a thing the doctor would probably think I’m crazy right?
