Covid-19 has underscored the importance of global health for the entire world, highlighting not only how such viruses spread through human movement and interactions, but also the links between health and other aspects of our lives such as the economy, jobs and the environment. It is clear that we are now all at risk, our lives made precarious by this daunting new disease.

In their absence there are adverse consequences not only for those who are sick, but also for the doctors who care for them.
