Great new work from @dotnagy.bsky.social who has developed EpiSENTRY which performs sample size calculations for public health WGS surviellance studies. She applies to data from the NEKSUS study to estimate how much sequencing is enough for GNBSI surviellance in England. @modmedmicro.bsky.social

So without much fanfare, a quiet corner of surveillance data shows that simple interventions have massively changed mortality. Probably represents a lot of Africa but we don't have complete data. Full paper here: link.springer.com/content/pdf/...
