Respiratory Syncytial Virus (RSV)

RSV Surveillance Has Begun

In Idaho, RSV surveillance efforts officially began the week ending October 12, 2019 and activity is low and sporadic across the state. 

The beginning of the RSV season, or season onset, is adapted from the National Respiratory and Enteric Virus Surveillance System (NREVSS). RSV season onset occurs in the first of two consecutive weeks during which the reported total percentage of specimens testing positive for antigen is ≥10%. 
RSV activity usually occurs at a low level in the summer and early fall months and then begins to rise sharply in late fall. We will continue to gather surveillance data and provide weekly updates once the season has begun as well as throughout its duration. 

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