Respiratory Syncytial virus (RSV)


RSV Season Has Ended

In Idaho, Respiratory Syncytial Virus (RSV) season officially began the week ending December 12, 2015 and ended the week of May 21, 2016. 

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 numbers have declined sharply, RSV activity usually occurs at a low level in the summer and fall months. We will resume gathering weekly updates beginning the week ending October 7, 2016. 

We wish to thank all the participating laboratories for their contributions during this RSV season.
