A young woman who tested positive for coronavirus has documented her isolation and recovery journey on social media.

Bridget Wilkins, 29, from Brisbane, tested positive for coronavirus after she came back on a Qantas flight from London via Singapore in early March.

She was one of the nation's first confirmed cases, and said she didn't know much about the virus at that time.

"It was quite scary when I got that phone call," she told ABC 7.30. "The first question I asked was, 'Am I gonna die?' That sounds a bit dramatic, but two weeks ago I didn't really know what coronavirus was."

Bridget started making video diaries on Instagram – originally just for her family and friends – and to give herself something to do.

She said the first six days were mild in terms of symptoms. "I had things you normally get when you have a flu or a cold… as the days wore on, I felt my condition deteriorated."

She said Days 8-10 hit her the hardest. "I felt like I was 80 years old," she said. "I definitely thought of my grandma at that moment because I recognised how hard it would be for her."

Bridget is now feeling better, but in a recent Instagram video she said she feels a "massive wave of emotion".

"We all know coronavirus is not gonna be as deadly as other things like SARS or bird flu or whatever else, but what it is is it's fearful, and fear is bred out of uncertainty," she said on Instagram.

"So I hope if I can provide certainty on what happened to me, it might provide it for others, and there'll be a little less fear in the world."
