Coronaviruses are a large family of viruses common in many different species of animals, including camels, cattle, cats and bats. Rarely, coronaviruses that infect animals can infect people, as an example of MERS-CoV and SARS-CoV. Recently, in December 2019, a new coronavirus (SARS-CoV-2) was transmitted, which was identified in Wuhan in China and caused COVID-19, which was then disseminated and transmitted from person to person.

COVID-19 is a disease caused by the coronavirus, called SARS-CoV-2, which has a clinical spectrum ranging from asymptomatic infections to severe conditions. According to the World Health Organization, the majority (about 80%) of patients with COVID-19 may be asymptomatic or oligosymptomatic (few symptoms), and approximately 20% of the detected cases require hospital care because they have difficulty breathing, of which approximately 5% may need ventilatory support.
