To add to this and a word of warning from personal experience that daily home rapid antigen testing will not prevent the spread of Covid. I recently attended a work meeting with about 30 people (everyone fully vaxed/boosted, wearing masks). A person attending the meeting had very mild "cold" symptoms that day but said they had tested negative twice (rapid antigen). Two days later, the person reported that they had come down with Covid. 8 of us attending the meeting (about a quarter), including myself, came down with Covid and became sick. I think we caught it during a lunch break, held outside under a covered patio, where people took their masks off to eat and drink.
I started daily home testing (rapid antigen) right away and tested negative until having a positive test on the 6th day after being exposed. I started isolating as soon as testing positive but unfortunately had already spread the virus to a family member who lives with us. Fortunately, neither of us required hospitalization but we were both sick (fever, coughing, extreme fatigue), and it took a few weeks to fully recover. PCR testing is much more sensitive than rapid antigen and may have detected the virus much earlier in the infection before having spread to others. As Heidi points out, very few people at home have access to daily PCR testing with rapid results.
