Coronavirus is one of the most dangerous and contagious illnesses that arise from the introduction of host organisms into the biological system. As of March 2022, this sickness had caused more harm than good, with 479 million cases and 6.12 million deaths worldwide. These illnesses are unpredictable sources of social, financial, and economic distress. The rising incidence of infections is the most concerning aspect. Human coronaviruses were discovered in the 1960s using two distinct ways in the United Kingdom and the United States, while the first reports of coronavirus infection in animals occurred in the late 1920s when an acute respiratory infection of farmed hens developed in North America. Although some estimates place the common ancestor as far back as 55 million years or more, reflecting long-term co-evolution with bat and bird species, the most recent common ancestor (MRCA) of all coronaviruses is thought to have lived as recently as 8000 BCE. Coronaviruses have a single-stranded, positive-sense RNA genome that ranges in size from 26.4 to 31.7 kilobases. When the viral spike protein binds to its matching host cell receptor, infection occurs. There is no specific, effective, or 100 percent cure for coronavirus as of 2021, but supportive care, which includes treatment to relieve symptoms, fluid therapy, oxygen support, and prone positioning as needed, as well as medications or devices to support other affected vital organs, is the cornerstone of COVID-19 management.
