Origins and Spread of Coronaviruses: Lessons learned from SARS, MERS, and COVID-19
Drs. Denis Jacob Machado and Daniel Janies
Coronaviruses have been known to be important to agriculture, economy, and human health for decades. We call the 2019-20 coronavirus (SARS-CoV-2) a novel virus. However, as the name suggests, SARS-CoV-2 shares common ancestry with the SARS-CoV, the Severe Acute Respiratory Syndrome virus of 2002-03. We will illustrate the origins of five lineages of coronavirus that infect humans. We will illustrate the origins and spread of these pathogens over time, space, and various hosts and what this information means in terms of public health preparedness.
