This just keeps getting worse

So I(17M) am having a horrible time because my uncle came over Monday night and the next morning he was sleeping in my room on my little brother’s former bed since we shared a room and I would not care if I was not terrified about the potential germs in there (specifically THOSE types of bodily fluids) because I have private moments in that room on my bed (which had been on the bare mattress for almost a year) and I did not sleep in there for fear of those bodily fluid germs spreading but now I see it was just increasing exposure of my family members (specifically my toddler/baby cousins and my little brother) because I had piles and piles of dirty clothes that had those dirty bodily fluids on them and he was in that room came into contact with those clothes put his charger into the pile of clothes to reach an outlet and of course that means the charger is filthy and he like I mentioned was sleeping on my little brother’s bed(Little brother does not use it anymore) which I think was infected because it was in the room next to my mattress so I know I bumped into the bed or maybe touched it without washing my hands after those private moments so it is infected and my uncle used it, slept on it so he spread those germs on himself and his things and then around our house and the snacks we eat. I did text him when I went to school that morning after I found him in there I sent this “Also My room is not clean and I am worried your stuff might be/get infected or dirty because of my dirty clothes and the other dirty stuff in there and I did not clean the bathroom and other stuff and so just don’t want you to get germs on your stuff like your charger or clothes or shoes and spread it to other or stuff “ and he responded “Darrell stop being a germ freak. If you were really concerned it would be clean all the time. But I can clean it up. “ and of course he decides to clean my room himself exposing himself even more not only did he put my dirty clothes on my mattress but also my little brother’s clothes and he just like kept doing it he kept cleaning my room and he washed my socks which were used during those private moments with my little brother’s clothes which is gross and means he touched those bodily fluid socks and the washer and everything else people in the house will touch and he also touched my IPad which I used during those private moments I had and I have not cleaned it off in a long long time so I know it is filthy with bodily fluid germs and I know he did not wash his hands after so those bodily fluid germs got everywhere his stuff, our stuff, everything and he has kids(my baby/toddler cousins) so when he touched their stuff that is in his bag it is infected so they will get it on them. And he still slept in there today and he had his stuff on the dirty bodily fluid floor so his glasses wallet and stuff was infected and was covered in dirty blankets like when I say dirty I mean it so I texted him again saying, “[Uncle name] the covers you are using are dirty both of them are they both have bad “germs” and I needed to wash them. The whole room has those bad “germs” and that is why I did not want anyone going in there and such I was terrified that someone would go in there and get those germs on them and I was worried about it getting on you and then it getting on the kids and your stuff especially since you were moving my dirty clothes and those bad “germs” were there too and I am sorry I did not say anything sooner” but this just issued him to wash the stuff but that does not change the bodily fluid germs he got on himself. I want advice I am terrified he touched his kids metal water bottles he put them in his bag and his charger on top of the bottles so now those are infected the bag, the metal water bottles and everything he touched when he was in my room and did not wash his hands so appliances like the fridge, stove, dishes, microwave and our countertops, seats and food. I need advice I am a sick person whose negligence and terrible hygiene let this happen I did not even mention the bathroom how dirty that was or the shower I use which he used that I did not clean so the curtain, soap container and shower and it’s handles and the door handles to my room and the bathroom all most likely had bodily fluid germs on it and now it will be spread to vulnerable kids and my family my brother I feel sick I do not feel like I mentioned all of it and I feel like if I miss something I am not telling the full story and risking more people. I know my uncle is going to sleep in there again and idk what to do. Update: He was in there sleep again today and he was charging his phone and he put his phone on the table in my room which I know is filthy because I touched it without washing my hands after a private moment and the same goes for the outlet he put his charger into and he put his other chargers on my bed and on top of this used my dirty adapter to plug his charger into so of course he got exposed again and I am at a loss.
