Long-Term SARS-CoV-2 Findings Related to Persisting Viral Antigen and Inflammation Resemble Those Reported for Influenza Virus and Respiratory Syncytial Virus - Published Aug 24, 2024
Abstract
Recent studies have documented prolonged expression of viral antigens and RNA and associated inflammation after infection with SARS-CoV-2 in a substantial proportion of infected patients. The persisting SARS-CoV-2 effects and findings, with inflammation associated with continued detection of viral antigens, especially resemble those previously reported for influenza virus, as well as respiratory syncytial virus (RSV). The reports indicate the need for improved insight into the mechanisms whereby post-SARS-CoV-2 infection-related illness is apparently more common and perhaps even more persistent after infection than observed for other respiratory viruses.
Keywords: SARS-CoV-2; influenza virus; respiratory syncytial virus; viral antigen; viral RNA; persisting inflammation; asthenia
