A decade after SARS: strategies for controlling emerging coronaviruses

Two novel coronaviruses have emerged in humans in the 21st century, Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) and Middle East Respiratory Syndrome human coronavirus (MERS-CoV), both of which cause acute respiratory distress syndrome (ARDS) and have high mortality rates. There are no clinically approved vaccines or antiviral drugs available for either of these infections; thus, a priority in the field is the development of effective therapeutic and preventive strategies that can be readily applied to new emergent strains. This review will: describe the emergence and identification of novel human coronaviruses over the last 10 years; review their key biological features, including tropism and receptor use; and summarize approaches to develop broadly effective vaccines
