Pinning hopes on the vaccine is not the right coronavirus strategy, expert says

While many hold out hopes for a vaccine to end the epidemic, one expert warns that vaccines are just part of the solution. Mask-wearing, shutting down some businesses, limiting large gatherings, and finding potential treatments will continue to be critical as a vaccine is still months away, and may not be completely effective even when there is one.

Five Things to Remember When Interpreting Epidemiologic Data

We know that the number of cases we have on record is an underrepresentation of the true burden for several reasons. Some underrepresentation is because testing for SARS-CoV-2 might not be available for the infected person… Another factor is that not everyone will need to see a doctor for COVID-19. The World Health Organization (WHO) published a very detailed report about the outbreak of COVID-19 in China and found that 80% of cases were mild or moderate. Since then, there have been studies that have identified infections in people who never develop symptoms. If someone gets infected and recovers on their own, then public health may never find out about the case.
