With #influenza rampant in the U.S. (red line graph), this is a good time to mention that the N.American #vaccine strains in the shot are excellently matched to H1/H3 viruses circulating. Here in the U.S. the CDC reported flu cases are <1% FluB. For FluA (~99%) we have ~21% that are #H1N1 pdm09 clade related, and ~77% #H3N2 all of which are isotyped as exclusively being clade 3C.2a1b.2a.2.

Researchers use initial exponential growth rates to estimate the R0 of #H1N1 influenza and #COVID outbreaks in 43 U.S. cities and find that despite similarities, epidemics starting in the same location may differ in initial progression.
