Our analysis of the entire cohort suggests that IFN-α2, IP-10, IL-1RA, IL-6, eotaxin, IgA, and IgM are prognostic markers that can be monitored in mucosal fluids and blood at the time of diagnosis or shortly after to forecast disease progression and aid in treatment plans following infection with a novel respiratory virus. The gene discussed is CXCL10; the disease is infection.
