Respiratory Syncytial Virus (RSV)

RSV Surveillance Has Begun


In Idaho, Respiratory Syncytial Virus (RSV) surveillance efforts officially began the week ending October 21, 2017.

Activity is: Sporadic

Infants and children at risk for severe RSV infection can receive monthly doses of palivizumab (Synagis™) as prophylaxis during the RSV season. Voluntary RSV surveillance is conducted to inform healthcare providers about RSV trends in Idaho that may impact prescribing recommendations for palivizumab (Synagis™).

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 RSV specimens testing positive is ≥10%. Traditionally the RSV season in Idaho is December through April.

The percentage of patients testing positive for RSV remains low in Idaho. 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.
