COVID-19 General Information

Since January 2020, WHO has published more than 100 documents about COVID-19. Of these, more than half are detailed technical guidance, on how to find and test cases, how to provide safe and appropriate care for people depending on the severity of their illness, how to trace and quarantine contacts, how to prevent transmission from one person to another, how to protect health care workers, and how to help communities to respond appropriately.

This review assesses the available peer-reviewed literature on the association between smoking and COVID-19, including 1) risk of infection by SARS-CoV-2; 2) hospitalization with COVID-19; and 3) severity of COVID-19 outcomes amongst hospitalized patients such as admission into intensive care units (ICU), use of ventilators and death.

This Technical Brief presents workarounds—tips and tricks to use digital platforms—to conduct pretests virtually. In this document, two instances for virtual pretesting are presented: the development of social and behavior change (SBC) materials and the development of job aids. Both use similar processes, but with specific differences that are highlighted in this document.


In this course, created by the Imperial College of Londona, the students hear directly from world-class experts about the theory behind the analyses of COVID-19 and its spread, while learning how to interpret new information using core principles of public health, epidemiology, medicine, health economics, and social science. They will be able to watch regular situation reports about the state of the epidemic, provided by the researchers of J-IDEA and its director Professor Neil Ferguson.
