Coronaviruses are single-stranded, positive-sense, enveloped RNA viruses in the nidovirales order that are categorized into four genera: alpha, beta, gamma, and delta. The SARS-CoV-2 virus associated with the COVID-19 epidemic is a beta-coronavirus. Seven known coronaviruses affect humans: HCoV-229E, HCoV-OC43, HCoV-NL63, HCoV-HKU1, MERS-CoV, SARS-CoV, and SARS-CoV-2. Many coronavirus-related illnesses are mild. In fact, coronaviruses were first studied in the 1960s as being agents of the common cold [14]. Nevertheless, of these viruses, only MERS-CoV, SARS-CoV, and SARS-CoV-2 are associated with potentially severe symptoms and fatal outcomes [15].
