Rsv what do I do?

I just went to the doctor today with my little one he’s 2 months old and he tested positive for rsv. We have Christmas parties this weekend some with just adults and another with kids and adults he’s probably had rsv for a week already cause he didn’t really show the sings other than coughing which started last Monday the 9th and that didn’t get worse till last Thursday so I didn’t take him in till today Monday the 16th My question is should we skip all parties or should we be ok to take him with us? Idk what to do I didn’t think to ask the doctor because I didn’t think he was going to be positive. I don’t want to miss his first Christmas’s but I don’t want anyone to get sick either.
