One hundred hospital staff at The Alfred have been sent home for 14 days of isolation after a cluster of coronavirus cases in the cancer ward.

Three cancer patients have died at the hospital in the past week. Another two patients and 10 staff in the haematology and oncology ward have tested positive to COVID-19.

About 100 staff from the ward have been sent home to go into isolation since the outbreak last week, a spokeswoman from The Alfred confirmed on Friday.
