So the first possibility is that a person, undetected through that routine testing, might have been a case and came into contact with the case we have discovered. To cover off this hypothesis, we are re-testing that workplace and, of course, going over the records of previous testing. The next question is: could transmission come from an object that this worker was in contact with? As has been said, this is not recorded in the scientific literature, yet, none the less, we are considering this possibility, because we want to take all the opportunities to improve our systems that we can. We know from the scientific literature that COVID can be recovered from surfaces up to seven days after it is deposited there, and it can be found to be living—that is, still capable of reinfecting other people. However, this is much harder to do in practice, and it is much harder to recover COVID from textiles, so the possibility of assessing whether this happened in the laundry is not really feasible.
