Respiratory Syncytial virus (RSV)
RSV Season Has Ended
In Idaho, Respiratory Syncytial Virus (RSV) season officially began the week ending December 17, 2016 and ended the week of April 1, 2017.
The end of the RSV season, or season offset, is adapted from the National Respiratory and Enteric Virus Surveillance System (NREVSS). RSV season offset occurs in the last of two consecutive weeks during which the reported total percentage of specimens testing positive for antigen is ≥10%.
Although the number of RSV laboratory tests reported to public health have declined sharply, RSV activity usually occurs at a low level in the summer and early fall months and then begins to rise significantly in late fall. We will resume gathering weekly RSV laboratory data beginning in October 2017.
We wish to thank all the participating laboratories for their contributions during this RSV season.
