Authorities have confirmed Brisbane’s mystery COVID-19 case is the highly contagious UK strain.

The 26-year-old tradesman from Stafford tested positive late last night and is believed to have been infectious in the community since Friday, March 19.

He was admitted to the RBWH overnight.

It’s also been confirmed to be linked to a cluster from 2 weeks ago, when the PA Hospital doctor caught the virus from a patient.

Queensland Chief Health Officer Dr Jeannette Young said it’s believed there is one “unidentified intermediary” who had passed the virus onto the man.

“We will know more in the next 24 hours, but in the meantime, those identified as visiting the locations in today’s Public Health Alert should immediately get tested and isolate until you receive your results.

“Additionally, anyone identified as a close contact will be contacted by the Public Health Unit and required to quarantine.”

From 12pm today, aged care, hospitals and prisons will be closed to the public in the Brisbane City Council and Moreton Bay Regional Council areas.

Dr Young requested people in a crowded area, such as entering stadiums for sports game or on public transport, wear a mask.

Everyone who has been to a contact tracing location is asked to come forward for testing.

Additionally, anyone in Brisbane and Moreton Bay who develops symptoms should be tested and isolate immediately.
