There are cases where you can know which exposure is responsible because you did RNA sequencing and can use the mutations to trace the route of infection. Given that we however don’t have cheap enough RNA sequencing to widely deploy it, it seems to me unlikely that the 27-day outlier is backed by such considerations.
