Would you keep your distance from family if they constantly get your child sick?

My parents watch my sister's two kids every day after school because both my sister and her husband work. My mom also volunteers in my nephew's kindergarten class every week. As a result, my parents (and my nephew and niece) are always sick. Seriously, always. Classroom germs, ugh!

I am fortunate to be able to be a SAHM to my 2 year old daughter. She loves to visit her grandparents (sometimes her cousins, but they are kind of bullies, but that's beside the point. They are always at my parents' house). Every single time we visit, she and I get sick. What's worse is that we get a lot sicker than they do. (I have asthma so respiratory illnesses always last longer for me). It's gotten to the point where I have to plan to be sick after we go over there because even if we wear masks and practice good hygiene, my 2 year old niece especially coughs all over the place and touches everyone on their faces and we end up sick. My daughter and I just got over a particularly long and rough bout of covid and were well for about 5 days and then we saw them all for Christmas and now we are coughing and vomiting again. We used to go over at least once weekly to visit but since my mom started volunteering in the classroom starting in September, we can't go over without getting quite sick.

I love my family and it's not their fault they are sick all the time, but I don't want my daughter and I to also be sick all the time. We are unable to visit my daughter's 96 year old great grandma for weeks on end whenever we are sick. We had to cancel a trip to Disneyland that we planned for a year because my mom got covid from my nephew's teacher and then we got it from her. I've been incredibly careful to not get covid and that was our first time getting it so it was very disappointing.

Anyway, it's a bummer. What would you do? Would you just be sick all the time and see your family often? Would you see them only on special occasions? Please no hate, I'm just curious what you would do in this situation.

Thanks!
