1/ Although the COVID-19 pandemic is unprecedented in many ways, our vulnerabilities to infectious disease threats has been long known to those of us in public health.

2/ Back in January, I worked with colleagues @JHSPH_CHS to release a special issue of articles previously published in our journal of relevance to nCoV. And we made them all free to read. Even as I go read the articles again now, I see many important lessons.

3/ “A significant proportion of the respiratory protective device supply chain is produced offshore and may not be available to the US market bc of export restrictions, which may favor in-country rather than foreign demands.” (2017)

4/ “The world has turned its attention to other problems...but the conditions that led to the emergence of SARS and its rapid global spread largely remain unchanged. **We forget these lessons at our peril.**” (2011) by @JenniferNuzzo

5/ post 9/11 “the more officials tried to reassure the public, the more the public was distrustful. The trauma of the terrorist events and the displacement from their housing, work, and schools exacerbated their anxiety and made them even more dubious about gov assurances” (2003)

6/ This one subheaders that include “SARS – How many wake-up calls will it take?” and “Repairing State Public Health Laboratories” and “Revitalizing Public Health Cannot Be Achieved on a Piecemeal Basis.” Enough said. (2004)
