There are effectively two #COVID19 epidemics in the US at this moment; one largely resolving epidemic comprised of non-variant viruses and one growing epidemic of B.1.1.7. Together they have resulted

This headline is highly misleading! 33 mutations were identified in the study but this does NOT equate to 30 different strains. Only 11 viral isolates were sequenced so it's not

New preprint. We estimate the transmissibility of #SARSCoV2 lineages based on their genomic makeup. Overall, transmissibility of #SARSCoV2 went up over time, but fitness of individual clades tends to decay

(1/n) We gathered and analysed genetic and epidemiological data related to the #COVID19 outbreak in #Iran to gauge its size in late Feb - early Mar and estimate the likely

The drivers of the #COVID19 epidemic in India are certainly multifactorial, but we have now seen the viral lineage B.1.617 linked to this epidemic continue to increase in frequency in

Great story in @nytimes about how #COVID19 spread to NY, based on genomes posted by @AdrianaHeguy @VivianaSimonLab & others to @GISAID. @nextstrain maintains fabulous visualizations of these data. Thought I'd

While the other four boroughs take a welcome slight rightward turn, the #Bronx continues its trajectory of increased deaths in #NYC from #Covid19.Now one person in 1,262 in the Bronx

Mode info COVID:Donc l’équipe de l’IHU a sequencé plus de 300 génomes de SARS-CoV2. Donc j’ai regardé la publication d’un peu plus près pour voir si on pouvait y trouver

I was hesitant to bring attention to this but I suspect it will be picked up soon. I am concerned that a recently posted preprint will cause another panic about

We now have enough #SARSCoV2 genomic data from different states to make some broad conclusions about how the #COVID19 epidemic has unfolded in the US. 1/14 We see a spectrum

I want to talk about a toy model for reasoning about what viral genomics can and cannot tell us about #SARSCoV2 transmission.Suppose viral isolates from two people have *identical* genotypes.

Voor diegenen die naast mijn tuin ook graag een grafiek zouden zien van de verspreiding van de Indiase variant B.1.617.2 - die ziet er op basis van de (relatief beperkte)

There are a lot of phylogenetic trees getting bounced about in the midst of #COVID19 and they’re getting really really big. A phylogenetic tree is a valuable resource mid #pandemic

There is a lot of Twitter chatter surrounding a rumor that circulation of #COVID19 in California in fall 2019 has resulted in herd immunity. This is empirically not the case.
