Comparison of coronavirus epidemics: SARS, MERS, COVID-۱۹

Background and Aim : From ۲۰۰۲ to ۲۰۱۹, three deadly human viruses broke out, all three coronaviruses of the family (Coronaviridae) belonging to the beta-coronavirus class, and their genetic material is positive in the form of a single-stranded ribonucleotide chain. The aim of this study was to compare the coronavirus epidemics of SARS, MERS, and COVID-۱۹.Methods : The present study was a brief review study designed in ۲۰۲۱. PubMed / Medline and Scopus databases were used to search for similar studies and extract content. Selected keywords for the search included “Coronavirus”, “COVID-۱۹”, “SARS”, “and MERS”. Summaries of articles published in congresses and conferences were excluded from the study. Initially, ۵ articles were finally evaluated.Results : Various studies have shown that SARS, MERS and COVID-۱۹ coronaviruses became prevalent in ۲۰۰۲, ۲۰۱۲ and ۲۰۱۹, respectively, and their mortality rates are estimated at ۱۰, ۳۴ and ۴%, respectively. The incubation period of coronavirus is ۵-۶ days in MERS, while SARS is ۲ to ۷ days and Covid-۱۹ is ۲ to ۱۴ days. COVID-۱۹ is more contagious than SARS and MERS and has a high rate of spread, but the mortality rate in MERS is higher than that of SARS and COVID-۱۹.Conclusion : The results of various studies showed that all three types of coronavirus have the same symptoms as fever, chills, fatigue, headache, cough, and shortness of breath. The viral composition of Covid-۱۹ is ۷۹% and ۵۰% similar to that of SARS and MERS, respectively, so studying the SARS and MERS viruses can greatly enhance human immunity to COVID-۱۹.
