Between 24 September 2026 and 7 October 2026 the tracker indexed 1 new peer-reviewed study and 17 clinical-trial updates across 8 post-viral and post-infectious conditions.
Note: fewer than 3 new studies were indexed in the 7 days to 7 October 2026, so this issue covers the 14 days from 24 September 2026. Some items may therefore also appear in the previous issue.
