Arizona Flu Alert!!!

The following alert was received from the Arizona Health Alert Network…..

Influenza activity in Arizona started early this season and has been increasing over the past few weeks; the Arizona Department of Health Services (ADHS) categorized activity as Widespread this week. Laboratory-confirmed influenza cases have been identified in fourteen counties, and an estimated 1,000 cases were reported by laboratories in the past week. Most cases are caused by influenza A, predominantly influenza A (H3), but there are also a low number of influenza A (H1N1) pdm09 (the 2009 influenza pandemic strain) circulating as well. A fair number of influenza B cases have also been reported.

We would like to remind everyone that it is not too late to get a flu shot. Influenza vaccination is the best prevention against flu, and influenza activity in Arizona usually lasts through the spring months. National data indicate that this year’s vaccine is a good match to the circulating viruses. Flu vaccination locations and other information can be found at or
