A Comparison of Mortality-related Risk Factors of COVID-19, SARS, and MERS: A Systematic Review and Meta-analysis

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a novel zoonotic pathogen. It is responsible for Coronavirus Disease 2019 (COVID-19) [1]. The COVID-19 pandemic has imposed a heavy burden on global health and medical systems [2]. A whole genome scan has shown that SARS-CoV-2 has a 79% similarity to Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV), and a 50% similarity to Middle East Respiratory Syndrome Coronavirus (MERS-CoV) [3]. Currently, SARS-CoV-2 is classified as a SARS-associated coronavirus and taxonomically belongs to the subgenus of Sabek virus [3].
