Brisbane residents have been shocked this morning to hear of a new COVID case in the community with authorities unable to pinpoint how the man fell sick. Here are your questions answered.

WHAT'S HAPPENED?

A 26-year-old Stafford man has been infectious in the community since last Friday. He began feeling sick Monday and stayed home until seeking a COVID test Thursday at Nundah, with the result coming back at 10pm.

HOW DID HE GET SICK?

He hasn't been overseas and authorities don't know where the case has come from. Authorities are waiting on genome sequencing results to see if it's linked to any previous cases that have been out in the community. Chief Health Officer Jeannette Young said "of course" it's concerning, but Premier Annastacia Palaszczuk has told people not to panic. The genome sequencing should come back late Friday or Saturday morning.
