Boyfriend had COVID months ago and wants to see me on his birthday. What should I do?

My boyfriend and I broke up in March during the beginning of the pandemic. He’s 27 I’m 28. We talked on and off and he said he felt sick. He lost his sense of taste/smell, had cold-like symptoms etc. but didn’t think he had covid. Four months later he messages me saying that he has covid, but was asymptomatic and feels better. He took a covid test in June and tested positive I think this is odd since he had symptoms in March, why wait 3 months later to get tested? He also had an antibody test done and was positive, says he isn’t contagious. He also says that he was retested and came back negative. His birthday is August 27th and keeps asking if I will visit him. I’m not comfortable with the idea of visiting, and have told him we can Skype instead and have his gift delivered and plan a virtual date. He is an essential worker so he’s working everyday since he has recovered, and caught covid from work so there is a chance he could catch it again. He also lives with his brother who is an essential worker and he invites his friends/girlfriend over regularly and doesn’t take the virus seriously. His brothers girlfriend is also planning to move in with them so there’s going to be 4 people living in one house. My boyfriend, his brother, the brothers girlfriend and their roommate Doug. Doug also brings over his new girlfriend to their house. Yesterday my boyfriend tried to tell me that the coronavirus is over so I have nothing to worry about and the numbers are low in New Jersey. I disagreed the numbers are slightly lower but it’s still spreading. How do I make it clear that I would like to celebrate his birthday but not risk my health? He continues to downplay the situation.
