That's a great question. I wonder if they took a belt-and-braces approach — as well as all the quarantining and testing, bring along some remdesivir/molnupiravir/ritonavir/etc, monoclonal antibodies and so on, just in case you get really really unlucky and one of the (presumably quite fit and healthy) people ends up with a severe case.
