Post COVID-19 Syndrome Clinical Manifestations: A Systematic Review.

BACKGROUND Coronavirus disease-2019 (COVID-19) is a global pandemic health problem which causes a wide spectrum of clinical manifestations and considerable mortality rates. Unfortunately, recovered patients who survive COVID-19 may continue to report wide varieties of clinical manifestations of multisystem affection such as fatigue, dyspnea, myalgia, anxiety, depression, acute myocardial infarction, peripheral and pulmonary embolisms. OBJECTIVE We aimed to assess the prevalence of post-COVID-19 manifestations. METHODS We conducted a systematic review on post COVID-19 manifestations by searching Pubmed, Scopus, Web of Science (WOS), EBSCO, Wily, and World health organization (WHO) databases. Screening, selection, data extraction, data synthesis and quality assessment were done by two independent reviewers. RESULTS Of 1,371 references, 817 references remained after duplicates, reviews; case reports, commentaries, and any article containing non-original information were removed. According to eligibility criteria for this systematic review, 12 studies were included for qualitative synthesis. The overall prevalence of post-COVID-19 manifestations ranged from 35% to 90.5%. Fatigue, dyspnea, neuropsychological disorders, and pain were the most frequent post COVID-19 symptoms. CONCLUSIONS This systematic review showed that 35% to 90.5% of recovered patients who survive COVID-19 continue to have wide varieties of clinical manifestations and fatigue, dyspnea, neuropsychological disorders, and pain were the most frequent post COVID-19 symptoms.
