Other Respiratory Viruses
View Previous YearsThe 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.
Activity Summary
For week 22 of 2022, rhinovirus was still the predominant circulating non-influenza respiratory virus, with approximately 17% of tested specimens positive for rhinovirus. Rhinovirus activity was stable this week but has been slowly trending upwards in the past few weeks. RSV activity also was stable this week and remains low overall, similar to previous seasons. Adenovirus activity increased slightly this week, though activity is still similar to the previous season. Human metapneumovirus activity decreased this week, though activity has been trending upwards over the past few weeks despite weekly variation. Parainfluenza viruses 1 and 2 detections remain low; however, parainfluenza virus 3 activity continues to increase and is circulating at higher levels than previous seasons for this time of year.
