Antigen test performance was improved among 227 (21%) paired swabs from participants who reported one or more symptoms at specimen collection (sensitivity=80.0%; specificity=98.9%; PPV=94.1%; NPV=95.9%). True positive = antigen-positive and real-time RT-PCRpositive; false negative = antigen-negative and real-time RT-PCRpositive; false positive = antigen-positive and real-time RT-PCRnegative; true negative = antigen-negative and real-time RT-PCRnegative; these definitions do not reflect results from viral culture. Further research is needed to evaluate the effectiveness of screening programmes at reducing transmission of infection, whether mass screening or targeted approaches including schools, healthcare setting and traveller screening.
