As reported in my blog here from Frontiers in Immunology:

“Treatment with antivirals such as interferons may significantly improve virus clearance and reduce levels of inflammatory proteins in COVID-19 patients, according to a new study in Frontiers in Immunology. Researchers conducting an exploratory study on a cohort of confirmed COVID-19 cases in Wuhan found that treatment with interferon (IFN)-α2b significantly reduced the duration of detectable virus in the upper respiratory tract and reduced blood levels of interleukin(IL)-6 and C-reactive protein (CRP), two inflammatory proteins found in the human body. The findings show potential for the development of an effective antiviral intervention for COVID-19.”
