Since SARS-CoV-2 infection was recognised in late 2019, the academic and clinical
emphasis has been on respiratory manifestations .

Post-COVID syndrome appears to be a multisystem disease, occurring even after a
relatively mild acute illness. Increasing evidence exists for direct multiorgan effects,
and indirect effects on other organ systems and disease processes, such as cardiovascular
diseases and cancers, through changes in healthcare delivery and patient behaviors . So,
the long term effects of covid-19 on individuals and health systems are becoming clear,
investigation across organ systems is urgently needed. Long covid, or post-covid
syndrome, is not one condition, and is defined by the National Institute for Health and
Care Excellence (NICE) as "signs and symptoms that develop during or after an infection
consistent with covid-19 which continue for more than 12 weeks and are not explained by
an alternative diagnosis . NICE guidelines recommend referral to post-covid syndrome
assessment clinics if post covid symptoms persist for 6-12 weeks . Pre-existing
conditions and risk factors are predictors of acute covid-19 outcomes (such as admission
to the intensive care unit and mortality, but the epidemiology of postcovid syndrome has
been less well defined . Because of the unclear medium and long term pathophysiology
across organ systems. When post-covid syndrome clinics are established, characterization
of the epidemiology of the disease will help with appropriate diagnosis, care, public
health interventions and policy, and resource planning. So, further research is highly
indicated.
