The synonyms for “long COVID” or “post-COVID conditions” are referred to as long COVID, long-haul COVID, post-acute COVID-19, post-acute sequelae of SARS CoV-2 infection (PASC), long-term effects of COVID, and chronic COVID. Since the occurrence of the pandemic in December of 2019, 10 variants of SARS-CoV-2 have been detected. Post-COVID pathologies are mainly observed in patients who have suffered severe COVID-19 infection. Nevertheless, for all COVID-19 patients, there is an augmented risk of “long COVID” or “post-COVID conditions”. To make the current post-pandemic healthcare situation worse, there is no single test for post-COVID conditions currently. At present, the developed countries and some developing countries are closely monitoring and documenting the symptoms, pathologies, drug therapies, and socioeconomic parameters. However, globally, many countries do not closely monitor, do not inform, and do not report the facts associated with “long COVID” or “post-COVID conditions”. Hence, this study was conducted by manually searching published articles up to June 2022 from the following databases: PubMed and Google Scholar. We searched for relevant clinical content using CDC and Lexi-Comp. We manually searched references of selected articles for additional information. Scientific articles were searched under English language restrictions. We conducted a search of the current literature to examine the “Long COVID” or “post-COVID conditions”. The current literature clearly indicates post-COVID pathologies that can increase morbidity and mortality.
