It took longer than usual- but Influenza is finally circulating in AZ- and we’ve moved to the “Regional” flu category now (Regional is sort of the middle of the scale).  The circulating strains in AZ (confirmed by our lab) are covered by this year’s vaccine- mostly our old friend the 2009 H1N1 virus and the familiar H3N2 virus.  The “Epi Curve” suggests that there’s more to come- with a peak in March.  Check out the most recent surveillance report for more info.  Meanwhile, the number of cases of Respiratory Syncytial Virus are still increasing- but that one looks like it’s closer to the annual peak.  Here’s this week’s RSV Report.
