Queensland Health Authorities have issued a warning to Brisbane residents after a woman tested positive to COVID-19.

Queensland's Chief Health Officer Jeannette Young says a health alert has been issued for a Virgin flight from Brisbane to Sydney on Monday, and to patrons of Greenslopes cafe “The Jam Pantry” on Sunday.

Dr Young says Queensland Health are still determining where the virus may have been acquired, but in the meantime are urging Brisbane locals to monitor their health and get tested immediately if symptoms develop.
