An unbridled host immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is likely to underlie severe cases of the disease and has been labeled a ‘cytokine storm syndrome’ (CSS). Here, we emphasize that categorization of syndromes triggered by a completely novel pathogen based on other seemingly similar, but potentially distinct, known entities is an inherently risky endeavor.
