Coronavirus disease (COVID-19) and SARS (CoV-2)

Erica Bronen

Coronavirus Disease 2019 (COVID-19) is a global health emergency caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Virus transmission, asymptomatic and presymptomatic virus shedding, diagnosis, therapy, vaccine development, virus origin, and viral pathogenesis are among the nine most essential research concerns discussed here. The Chinese authorities initially labelled the 2019-nCoV as causing an ongoing outbreak of lower respiratory tract sickness known as Novel Coronavirus Pneumonia (NCP). The World Health Organization later suggested the term COVID-19 for the condition. Meanwhile, the International Committee on Virus Taxonomy called 2019-nCoV SARS-CoV-2.
