As defined below, cytokine storm (high serum levels of granulocyte‐colony stimulating factor [GSCF], interferon‐γ inducible protein 10 [IP‐10], monocyte chemoattractant protein 1 [MCP‐1], macrophage inflammatory protein [MIP]‐1A, interleukin [IL]‐2, IL‐6, IL‐7, and tumor necrosis factor [TNF]) in COVID‐19‐infected patients results in pulmonary edema, dysfunction of air exchange, acute respiratory distress syndrome (ARDS), and acute cardiac injury and may lead to death. Here, TNF is linked to acute respiratory distress syndrome.
