The Yale #SARSCoV2 Genome Surveillance Initiative released its 7th weekly update. This time we took advantage of phylogeography to gain some insight into how and where #COVID19 is spreading within #Connecticut Full report • https://covidtrackerct.com/portfolio/update7/ …pic.twitter.com/J1UAJYOLCk

Disclaimer: these results are preliminary, and some patterns of viral spread may change as more data are available. → In a few words: by using 117 #SARScov2 genomes from CT, we found sustained #COVID19 transmission, especially within/between Fairfield and New Haven counties.pic.twitter.com/sHMm9CC8WX

Last month we revealed multiple introductions of #SARSCoV2 from NY and from the West Coast (WA state) to Connecticut. Now we see viral spread among towns in CT, spanning form the western towns of Ridgefield and Easton, to Haddam, Westbrook, and the Greater New Haven area.pic.twitter.com/ibdkCgTRQY

Surprisingly, using genomic data, we have not yet found evidence of interstate spread between CT and Massachusetts (MA), which would be detected if MA genomes are found interspersed among CT genomes (mint) all over the tree. In fact, MA genomes (pink) cluster mostly together.pic.twitter.com/O3v4m8WHp9
