In Idaho, Respiratory Syncytial Virus (RSV) season officially began the week ending December 13, 2008. The definition for season onset is adapted from the National Respiratory and Enteric Virus Surveillance System (NREVSS). RSV is considered widespread in Idaho in the first of two consecutive weeks during which the reported total percentage of specimens testing positive for antigen is
≥ 10%.
High-risk infants should have already begun palivizumab (Synagis®) injections.
The end of the RSV season, or season offset, will occur in the last of two consecutive weeks during which the reported total percentage of specimens testing positive for antigen is ≥ 10%. The end of the 2007-2008 RSV season occurred the week ending April 19, 2008. Idaho Medicaid currently authorizes medical providers to administer palivizumab to high-risk infants until April 17. Please continue to check this website weekly for updates on Idaho RSV activity. If the 2008-2009 RSV season extends beyond April 17, the need for a 6th injection of palivizumab for high-risk infants will be reviewed by Idaho Medicaid on a case-by-case basis.
