Fresno and Visalia were at the top of a list of designated market areas (DMA) with recent flu activity gains, according to the Walgreens Flu Index.
The Index, which is compiled using weekly retail prescription data for influenza medications at Walgreens and Duane Reade locations, also found that California was No. 4 on the list of states with activity gains. The Index does not include markets where Walgreens has fewer than ten retail locations.
Fresno-Visalia was No. 1 for the most recent week’s list, ending last Saturday. The market area is currently marked at No. 100 for overall activity, at .59 percent the average flu index.
