This is the second lecture in the course "The Covid-19 Pandemic: Virology, Public Health, and Economics," taught by Prof. Jeffrey Sachs, Columbia University.

The course offers a comprehensive and up-to-date analysis of the global Covid-19 epidemic. We will consider the epidemic from multiple perspectives, including: the historical role of epidemics in human history; the basic epidemiology of SARS-CoV-2; the basic virology of SARS-Cov-2; the nature and causes of zoonotic diseases; the efficacy of Non-Pharmaceutical Interventions (NPIs) to control the epidemic; a comparative analysis of control measures in different countries; the economic and humanitarian consequences of the epidemic and ways to meliorate the crisis; the economics of vaccine development; and the role of international cooperation and global health institutions.

This lecture was delivered live to students from the Columbia University School of International and Public Affairs, University College Dublin, and Sunway University on October 15, 2020.
