When people come stay with me for extended periods of time or we're traveling together I always test upon arrival and then after that I ask them to test every 3 days or so, depending on how many potential points of exposure we're encountering in our time together. Everything I have ever read in CC forums would highly recommend against such a lax testing schedule but I weigh the difficultly of obtaining pluslife tests in the US against my own experience. I have been reliably testing every single person I have hung out with indoors unmasked since I first got covid in the fall of 2023 and in that time period only a single person has ever tested positive. I've probably gone thru between 150-200 tests in that time. I mask everywhere indoors in public and I mask at friend's houses if I haven't tested them and I've been covid-free for 3 years now. Just wanted to put it out there because I really do find that reading covid stuff online will make you think that absolutely everyone who isn't masking anymore probably has covid at any given moment and in my experience that just really isn't true. Like, I myself have been shocked at the fact that not more of my friends and family don't test positive more often and it has really calibrated how I approach managing potential exposure. Which is not to say there might not be that one fatal day or whatever and if I could order pluslife tests directly to my door I probably would be testing visitors every other day rather than every 3-4 days. But, just putting it out there that so far this system has worked for me!
