FOLLOW THE KEY COVID-19 PANDEMIC DEVELOPMENTS WITH DIGESTABLE VIDEO UPDATES
Note to new visitors: To view the over 100 COVID-19 Updates in this course, you will need to create a free account (it only takes a few seconds).
A novel coronavirus was first reported to the World Health Organization on December 31, 2019. The virus appears to have spread from Wuhan, China and has quickly led to a pandemic.
Dr. Seheult illustrates key developments about COVID-19 and SARS-CoV-2 pathophysiology, transmission, prevention, treatment options & trials, vaccine advances, data trends, as well as the response from governments, hospitals, and communities.
A lot has changed since we recorded our first video on a novel coronavirus outbreak on January 26, 2020. Please note that each updatevideo was produced with the best information we could access at the time of recording. Some videos were recorded well over a month ago and may contain information that has become outdated or replaced by better information or research.
That said, we believe each video contains concepts that have enduring value, and reviewing how the response to COVID-19 has progressed over time may be of interest to you as well.
We're committed to keeping our COVID-19 videos free for all to access. Please share them with friends and colleagues if you find them helpful.
