Respiratory Syncytial Virus Surveillance Data

Oregon and Southwest Washington RSV Surveillance

About this surveillance data

In Oregon, RSV is not a mandatory reporting disease. Test results reported via this surveillance project are based upon 23 active, voluntary sentinel laboratories reporting for 36 hospitals.

  • Data is tabulated and published as it is received from the participating laboratories, and thus participating laboratories are relied upon for data integrity.
  • Reports may be based upon rapid tests, DFA, cultures, and other test types; the test methods vary from laboratory to laboratory. The total number of tests may not reflect the total number of patients tested.
  • Surveillance begins the first week of October of each year and continues until RSV activity has dissipated.
  • 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. RSV season offset is the last of 2 consecutive weeks during which the mean percentage of positive specimens by antigen is <10%, or the mean percentage of positive specimens by PCR is <3%, whichever occurs last.
