A study of more than 11,000 Australians who tested positive to COVID-19 in 2022 has revealed almost one-in-five were still experiencing ongoing symptoms three months after their initial diagnosis, according to new research from The Australian National University (ANU).

The study was conducted in Western Australia (WA), with participants drawn from the almost 71,000 adults who tested positive to COVID-19 in WA between 16 July 2022 and 3 August 2022.

Lead researcher, Dr Mulu Woldegiorgis, said the results show the risk of developing long COVID from the Omicron variant is higher than previously thought.
