Previous studies on cytokine profiles in influenza and SARS‐CoV‐2 infections have demonstrated that immune dysregulation, along with elevated levels of chemokines (e.g., IP‐10) and proinflammatory cytokines (e.g., IL‐6, TNF‐α), is closely associated with disease progression and severity in viral infections. The gene discussed is CXCL10; the disease is influenza.
