Long COVID research

Mechanisms, cardiac sequelae, neurological presentations, clinical trials.

Long COVID has evolved from a symptomatology debate to a well-characterised multisystem condition. Relaylit tracks new mechanistic work (microclots, viral persistence, autonomic dysfunction), clinical trials, and policy reviews across biomedical and preprint sources.

Example brief
