A woman who contracted the mutant UK strain of COVID-19 and flew into Brisbane from Melbourne after clearing hotel quarantine has since tested positive to the virus again, prompting an urgent public health response.
Under the previous national protocols, the woman was allowed to leave after 10 days in hotel quarantine, and did not need to return a negative test before doing so.
But because authorities are so concerned about this new strain, those rules have now been changed.
So why was she allowed to leave hotel quarantine?
