COVID-19 - Scientific Evidence

All papers from SAGE or other sources should be viewed in context: papers represent the authors’ best assessment of the evidence at the time of writing. The picture is developing rapidly and, as new evidence or data emerges, SAGE updates its advice accordingly. Therefore, some of the information in papers may have been superseded and the author’s opinions or conclusions may since have developed.

Dozens of such models have been published and are in use throughout the world; there is no single standard model which everyone uses. Link to document available here.
