Respiratory Syncytial Virus (RSV)

RSV Season Has Ended

In Idaho, Respiratory Syncytial Virus (RSV) season officially began the week ending January 25, 2020 and the season ended the week ending March 14, 2020.

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 is ≥10%. 

Although the number of RSV reports to public health officials have declined sharply, RSV activity usually occurs at a low level in the summer and fall months. We will resume gathering weekly updates beginning in October.

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