Respiratory Syncytial virus (RSV)
RSV Season Has Begun
In Idaho, Respiratory Syncytial Virus (RSV) season officially began the week ending December 12, 2015 and an increase in activity continues to be reported 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%.
Numbers have begun to increase since December 12, 2015; 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 throughout the RSV season.
We wish to thank all the participating laboratories for their contributions during this RSV season.
