Flu Season Goes Into Overtime

Swine flu is still out there:

CDC has another snapshot of what the flu surveillance system is seeing up through week 23 (ending June 13)...[O]f the 2765 specimens tested in CDC's network of 150 laboratories, virtually all of the roughly 40% were influenza A (seasonal influenza B has all but disappeared; the others were not influenza). Not all the flu A viruses were or could be subtyped, but of those that were or could be, 98% were novel H1N1. IN other words, there's lots of flu around, but essentially none are the seasonal strains of last winter. They are almost all pandemic H1N1.
