Being around brother who was at a small summer camp (covid) while pregnant?

Im supposed to drive out to see my parents and brother for a week and my brother was previously at summer camp up until this Thursday. I told them my concern with him being at camp, so they agreed to pull him out for my sake of being pregnant. It will have been 10 days since he has been at camp by the time I get there and he won’t be attending any for the duration of my visit. Parents have been been pretty safe and wear masks anytime they go out. Would you trust it?
