In Australia, hotel quarantine has caused one outbreak per 204 infected travellers. Purpose-built facilities are far better, but we only have one (Howard Springs, near Darwin) and the federal government has to date refused to build any more.
But no cases of infections slipping thru the testing, no?
As far as I know none of our leaks have been by releasing an infectious person after a negative test result.
It’s possible for PCR tests to return negative for a very early (low viral load) infection though; that’s why for high-risk travellers we do PCR tests on days −3, 1, 5, 11, and 14 of the quarantine period. For low-risk settings, ie contact tracing, you only need to isolate until you get a negative PCR test result.
