Week 2 data: 280 (10.2%) PCR tests and 34 (10.1%) Ag tests detected RSV, as reported by 14 sentinel laboratories.

2022-2023 RSV surveillance in Oregon began on September 25, 2022. As of October 29, 2022, Oregon met criteria for season onset of RSV circulation. As defined by CDC, the RSV season onset is the first of 2 consecutive weeks during which the mean percentage of specimens testing positive for RSV antigen is 10% or the mean percentage of specimens testing positive for RSV by PCR is 3%, whichever occurs first. 24 laboratories in Oregon and southwest Washington participate in sentinel laboratory surveillance by reporting the numbers of RSV tests conducted and the number positive.

RSV-associated hospitalizations and rates are generated using data from the Respiratory Syncytial Virus Hospitalization Surveillance Network (RSV-NET). In Oregon, RSV-NET conducts population-based RSV surveillance in Clackamas, Multnomah, and Washington counties. For more information regarding Oregon RSV surveillance, please see: rsvdata
