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.

Activity Summary

For week 10 of 2020, rhinovirus was the predominant circulating non-influenza respiratory virus, with approximately 13% of tested specimens positive for rhinovirus. Rhinovirus activity appears to have begun increasing while RSV activity has continued to decline, both in trends similar to previous seasons. Human metapneumovirus detections were also particularly high compared to recent years. Parainfluenza virus and adenovirus detections have been consistent with previous seasons for this time of year.
