The following graphs depict the aggregate results of PDPH's respiratory virus surveillance. Care should be taken with the interpretation of these results.
These summaries display the provisional, year-to-date counts (or, in some cases, percentage positivity) of respiratory viruses by week of report. Comparable data for preceding years are shown as well.
All surveillance data are preliminary and are not intended for further distribution.
For week 9 of 2023, parainfluenza virus type 3 detections have reached a high for this season. Human metapneumovirus has decreased in detections, though detections remain higher than those observed in previous years. Adenovirus activity increased and is circulating at higher levels than previous seasons for this time of year. Parainfluenza type 1, parainfluenza type 2, rhinovirus and RSV have decreased in counts.
