When epidemics or pandemics hit, they usually hit the poor first and worst. We have known this for a while. The German pathologist Rudolf Virchow described this link between poverty and vulnerability to outbreaks in his "For there can now no longer be any doubt that such an epidemic dissemination of typhus had only been possible under the wretched conditions of life that poverty and lack of culture had created in Upper Silesia."
What we have not known, until recently, is how best to help the poor protect themselves from pandemics.
To understand why the poor are more vulnerable to epidemics and pandemics and what protections are required, we need to consider how outbreaks first start, how they spread, and how they affect individuals and societies.
