How these figures are counted
  • Trials on record is every trial tagged to this condition at any stage, except those withdrawn before starting or terminated early. Most are completed rather than ongoing, so this is a measure of research history, not of current activity. It is also smaller than the sitewide "trials tracked" figure, which does include withdrawn and terminated trials.
  • Recruiting now counts only trials whose registry status is "Recruiting". Trials listed as not yet recruiting or enrolling by invitation are excluded, so this understates how many may open to new participants soon.
  • Australian sites counts trials counted under "Recruiting now" that list at least one Australian site. A site being listed does not mean it is currently enrolling, and Australian trials registered only on ANZCTR are not counted yet, so this understates local availability.
  • Phase 3 trials counts trials counted under "Recruiting now" that are at Phase 3.

Understanding Long COVID

Long COVID is a condition where symptoms from a COVID-19 infection continue, come and go, or appear for the first time more than four weeks after the initial illness. These symptoms can vary a lot from person to person, but commonly include extreme tiredness, difficulty thinking clearly (sometimes called "brain fog"), breathlessness, headaches, and muscle pain. For some people symptoms are mild, while for others they can significantly affect day-to-day life, including the ability to work, study, or carry out everyday tasks.

In Australia, Long COVID affects a broad range of people — it is not limited to those who were severely ill with COVID-19. People of all ages can experience it, including those who had only a mild initial infection. Research suggests that some groups, including women, people with pre-existing health conditions, and those who were not vaccinated, may be at higher risk, though it can affect anyone. Australian health agencies have been working to better understand how many people are living with this condition.

Because Long COVID can look different for each person, there is no single standard treatment that works for everyone. Care is generally focused on managing individual symptoms and helping people pace their activities to avoid making symptoms worse. In Australia, this often involves a team of health professionals, which might include a GP, physiotherapist, psychologist, or specialist, depending on what symptoms someone is experiencing. If you have received this diagnosis, speaking openly with your GP about your specific symptoms is a good starting point for understanding your options.
