Reporting of human adenoviruses has declined since COVID-19

Research published in the U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report reveals a decrease in reporting of human adenovirus (HAdV) types since the beginning of the COVID-19 pandemic. Fatima Abdirizak, M.P.H., and colleagues at the CDC summarized data from the National Adenovirus Type Reporting System from 2017 to 2023, showing a decline in the number of specimens with HAdV typing results reported annually. Despite continued circulation reported through passive laboratory surveillance, reporting to the National Adenovirus Type Reporting System has decreased. The authors suggest that expanded laboratory capacity for typing HAdVs and enhanced reporting could provide better insight into circulation patterns and guide public health prevention strategies.
