Other Respiratory Virus Weekly Reports

Laboratory-Based Surveillance

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.

Week 17

For week 17 of 2022, rhinovirus was the predominant circulating non-influenza respiratory virus, with approximately 15% of tested specimens positive for rhinovirus. Rhinovirus activity was stable this week, and activity remains lower than the previous season for this time of year. 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 also increased this week. Parainfluenza viruses 1 and 2 detections remain low while parainfluenza virus 3 activity continues to increase, matching previous seasonal increases.

For week 6 of 2022, rhinovirus remained the predominant circulating non-influenza respiratory virus, with approximately 15% of tested specimens positive for rhinovirus, another increase from the previous week. RSV activity was stable compared to the previous week, though it remains lower than seasons before the COVID-19 pandemic. Adenovirus has continued to circulate at levels slightly higher than previous years. After consistent decreases the past few weeks, human metapneumovirus activity increased this week, though activity is lower than seasons before the COVID-19 pandemic. Parainfluenza viruses 1 and 3 both had very little activity, while parainfluenza virus 3 increased in activity.
