The ongoing Covid-19 outbreak is in many ways unprecedented, in both the scale of this challenge, the scale of public health response, and the historical context in which all this is unfolding. Covid-19 is the first global pandemic of the social media age, the first of the “alternative facts” era, and is occurring at a moment when politics and society seem to be in a state of accelerated flux.
Yet for all that is new about Covid-19, the disease still behaves like any number of prior epidemics. It is, for example, similar to the 2003 severe acute respiratory syndrome (SARS) outbreak, an event which created a number of lessons for our present moment. SARS was, in many ways, the best-case scenario for responding to a global infectious threat. The spread of SARS was contained fairly quickly by public health efforts, chiefly through the widespread use of quarantine. But even this relative success still had consequences for health. In 2004, I worked with colleagues on a study of SARS control and the psychological effects of quarantine in Toronto, Canada. We found among quarantined persons a high prevalence of psychological distress, including symptoms of depression and posttraumatic stress disorder (PTSD). A key takeaway: Even if we can halt the physical spread of a disease through the expeditious use of quarantine and social distancing, we will still have to contend with its mental health effects in the long-term.
