Study profiles the nose to predict immune response during COVID-19

SARS-CoV-2 resides in mucous membranes, making it easy to detect viral load in the nasal cavities. An international group of researchers has characterized the immunological and diagnosis characteristics of patients who may have or are confirmed with SARS-CoV-2 infection. The team found a distinct nasal cytokine profile that could help identify patients at risk for high inflammatory responses to SARS-CoV-2 infection.
