Yes. That has been shifting over time. When omicron arrived, the percentage of positive tests actually increased quite a bit. In the partially or non-vaccinated individual—both by land and air—that number is cumulative and was 7.2% in the last week we had the complete data for. From December 26 to January 1, it increased from 0.73% to 7%.
In the fully vaccinated, because this is an immune-evasive variant it still increased from 0.3% to 5.47%.
So even though these travellers have had pre-departure tests before they got on the plane, for example, they are still showing up positive on day one, and the unvaccinated individuals who were tested on the day eight tests are also showing positivity.
It does mean that when we can detect these travellers, then they can be isolated and reduce their ability to spread into the community.
