During the Belgian winter and spring season 2022-2023, we investigated the potential of used paper tissue (UPT) as a noninvasive sampling method for the diagnosis of acute respiratory infections. Screening for respiratory pathogens was done using an in-house developed respiratory panel for simultaneous detection of 22 respiratory viruses and seven nonviral pathogens. The method allowed the identification and typing of respiratory pathogens in symptomatic individuals, as well as in collective samples taken at a community level. Pathogens that were identified in nasal swabs could also be detected in concurrent UPT from the same patient. In all cases that tested positive on an antigen-detection rapid diagnostic test, the corresponding virus could be detected in UPT. The collection of UPT could be useful in epidemiological surveillance of severe acute respiratory syndrome coronavirus 2 and other coronaviruses, as well as other respiratory pathogens such as influenzavirus, respiratory syncytial virus, entero/rhinoviruses including EV-D68, parainfluenzaviruses, and Streptococcus pneumoniae. Multiple respiratory pathogens could be detected in UPTs of collectivities, confirming its applicability for community testing. This is especially interesting for screening in nursing homes, centers for the disabled, schools or other settings were taking nasal or nasopharyngeal samples is cumbersome.
