Abstract

With millions of people killed and billions affected worldwide, the coronavirus disease 2019 (COVID-19), which is brought on by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has created a disastrous situation. Through mutations, the virus is persistently propagating as different strains, sustaining its resurgence. Since vaccine development was accelerated, concerns have persisted regarding the vaccinations' efficacy and safety. Even though the COVID-19 pandemic has been contained, concerns regarding vaccines and the effects of SARS-CoV-2 infections have surfaced, casting doubt on their potential role in sudden death (SD) or sudden unnatural death (SUD). This is mostly because more and more young and middle-aged persons who were previously healthy are dying of sudden cardiac death. The scientific community should be made aware of this so that they may start investigating it and determine the causes of these changes, which will either contradict or demonstrate how SARS-CoV-2 infection, COVID-19 vaccinations, or both, contribute to SUD or SD. We report a case of SD in a person who was leading an active life until before the episode.
