IP‐10 promotes inflammation in Human Immunodeficiency Virus (Lei et al., 2019), H5 N1 Influenza A (Chan et al., 2005; Jong et al., 2006), Middle‐East Respiratory Syndrome virus (Chu et al., 2014) and SARS‐CoV (Chen & Subbarao, 2007) infections, thus its prominence early in SARS‐CoV‐2 infection, while unsurprising, may be important for understanding evolution of disease from initial mildly symptomatic to severe and sometimes fatal. The gene discussed is CXCL10; the disease is infection.
