14th Apr 2021 6:55 PM COVID-19 fragments have been detected in a closed ward of a Brisbane Hospital, weeks after it became the site where two separate clusters emerged. Ward 5D of the Princess Alexandra Hospital was closed in late March after a nurse and doctor treating infected returning travellers contracted the virus and unknowingly spread it through the community. Queensland Health revealed deep cleaning had been carried out last week by contractors engaged by the Department of Housing and Public Works. Additional cleaning will be carried out from Wednesday after further testing detected COVID-19 in the ward. Queensland Premier Annastacia Palaszczuk said it was unlikely the virus fragments were contagious.
