@wsbgnl The first part (not highlighted) is odd. Even if risk decreases on each exposure it can still be cumulative, and indeed would be unless someone thinks that getting covid again will cure previous long covid, or if risk drops immediately to zero (not claimed). So still odd.
@wsbgnl第一部分（未突出显示）很奇怪。即使每次暴露的风险降低，它仍然可以累积，并且确实会累积，除非有人认为再次感染新冠病毒将治愈之前长期的新冠病毒，或者风险立即降至零（未声明）。所以还是很奇怪。
