    Traffic lights for a storm?

    I enjoyed reading this article, however, the reference to a cytokine storm warrants clarification. An editorial in JAMA Internal Medicine doi:10.1001/jamainternmed.2020.3313 suggested little evidence for such a storm and this has been supported by more recent studies by Remy et al in JCI Insight (10.1172/jci.insight.140329) who demonstrated severe immunosuppression and Kox et al in JAMA (doi:10.1001/jama.2020.17052) who found multiple cytokines were reduced in severe COVID-19.
