Parents refusing to not kiss baby on mouth! Help!!

Ss

My daughter is almost a year now. I made it extremely clear before she was even born that I did not want anyone kissing her on her lips or face. My whole family has simplex herpes. The cold sores. So I really didn’t want to chance that. My parents completely blew it off and made fun of me and said basically they will do as they please with her since she’s their grand daughter. I’m very shy and tend to let people walk over me so this is hard. When she was born, of course they kissed her. They have been ever since. Even though I’ve talked to them a few times and asked not to. I even brought up that babies could die from contracting herpes but my dad says cold sores aren’t herpes and I’m wrong. The problem is he gets cold sore a lot. Like at least one every 2-3 months. I get one every few years but I know as soon as I feel one coming on to not kiss her anywhere, wash my hands constantly and hers. Another problem is I’m 99% sure my dad gave her thrush... he has white patchy stuff in his mouth and has for a while now. She got thrush and I told him sternly “do not kiss her anymore. She has thrush and you will get it to.” Kind of a gentle way so he doesn’t get offended but maybe stops. And he literally just says he doesn’t care and continues kissing her. I’m pissed. I got herpes from my parents kissing me. All of my siblings did. I do not want my daughter to get it. Let alone thrush. I also read that syphillis can somewhat look like thrush and now I’m freaking out because my dad has had this for a long time. And it gets really bad to the point he tells me he can’t eat, yet he does nothing about it. If he had syphillis he’d probably be dead by now from leaving it untreated right? How can I go about this in a gentle way? My mom just told me she has a bad chest infection but is still coming to my daughters birthday in a week even though I’ve asked her not to. My parents have no boundaries and constantly shame me and call me a bad mom for speaking up about this stuff. I don’t know what to do. I’m terrified of them and I need advice. Pls help
