Neutrophil extracellular traps are suspected to contribute to tissue damage in human COVID-19 and NETs are also released by neutrophils in SARS-CoV-2 infected hamsters.1,4 Therefore, we analyzed the virus-positive lesions in the nasal conchae for NET-formation by dual immunolabeling for myeloperoxidase and DNA-histone-1 complexes. The gene discussed is MPO; the disease is COVID-19.
