Should I ask my MIL to disinfect the toys?

my MIL's son and his wife have 2 kids and they live with her. well one of the kids is 10 months and he had a bad virus along with pink eye in both eyes and an ear ache in both ears. its been about a month since he has been sick and hes better now, i am going to visit them in about 2 weeks. i was wondering if i should ask my MIL to disinfect the toys that the little boy played with bc i dont wnat my 9 month old to get sick. its turning into a hle to just go home bc every time i get sick, my husband gets sick and our baby gets sick. is there anything else i should ask her to do?
