More than 32 million individuals have survived a confirmed COVID-19 viral infection in the USA [1, 2], and a substantial proportion of post-COVID survivors are suffering from prolonged, recurrent, and/or newly emerging symptoms that span across bodily systems and organs [3]. The spectrum of symptoms and disabilities observed in this setting has been alarming and suggests that the “post-COVID syndrome” is a pan-inflammatory disease with highly variable disease expression and consequences [4]. However, accurately and completely characterizing post-COVID syndrome is difficult because many individuals with acute COVID-19 infection were not hospitalized, and therefore were not tracked through standard, in-patient-based data reporting mechanisms to public health authorities [5].
