Why SARS-CoV-2 replicates better in the upper respiratory tract

What happens in our airways after infection with SARS-CoV-2? Researchers from the Institute of Infectious Diseases (IFIK) at the University of Bern and the Swiss Federal Institute of Virology and Immunology (IVI) have been able to show how the virus replicates in the respiratory tract and how the innate immune response there reacts. The findings can be used to develop antiviral drugs and preventive measures.
