@__philipn__ @wsbgnl Even on it's own, the phrase "in certain populations, the risk may be cumulative" is odd, because I can't see how it could ever not be in any population (again, unless covid cures previous long covid or per-infection risk drops to zero).
Maybe misstated "risk may increase"
@__philipn__ @wsbgnl 即使就其本身而言，“在某些人群中，风险可能是累积的”这句话也很奇怪，因为我看不出它怎么可能不会出现在任何人群中（同样，除非新冠病毒治愈了之前长期的新冠病毒或每次感染的风险降至零）。
可能误报“风险可能增加”
