Thanks to open data sharing via @GISAID, we've updated nextstrain.org/ncov with two additional #HCoV19 genomes from Wales and one additional genome from Washington State. 1/3
The two genomes from Wales each group the large European outbreak clade, but don't group together, suggesting separate introductions. Thanks to @SmallRedOne, @tomrconnor, @PublicHealthW, @WalesMicrobiol 2/3
The Washington State genome nests within the clade associated with community spread in King County and Snohomish County. Thanks to @seattleflustudy, @HelenChuMD, @lea_starita, @mjonasrieder, @debnick60, @JShendure, Jover Lee. 3/3

Thanks to incredibly fast & open data sharing by @UZH_Science @UZH_Virology @mihuber @ATrkola & GISAID, we've updated nextstrain.org/ncov with the first #COVID19 #SARSCoV2 sequence from Switzerland sampled on 26 Feb.

It sits near a Brazilian sample w travel history to Italy.
@UZH_Science @UZH_Virology @mihuber @ATrkola Minutes later, thank to the same great data sharing, we have a second Swiss sequence. This one links away from the first - in a group of sequences all with travel history to Italy, plus an Italian sequence from Lombardy.

#SARSCoV2 #COVID19 #coronavirus
@UZH_Science @UZH_Virology @mihuber @ATrkola And another fast update brings 4 more Swiss #SARSCoV2 #COVID19 sequences, thanks to quick work by @UZH_Science @UZH_Virology @mihuber @ATrkola @sschmutz_
& GISAID
nextstrain.org/ncov

These sequences link to the 2nd seq above - in the global group w travel history to Italy.

One of the most powerful aspects of genomic data for #COVID19 is the ability to make connections between seemingly disparate outbreaks. This is a thread describing one such possible connection. Please keep in mind this is only a hypothesis and not proven fact. 1/9
Thanks to rapid work by @UWVirology and @seattleflustudy we now have 13 #HCoV19 genomes from Washington State. All 12 of the genomes from community cases have grouped into an emerging outbreak clade. 2/9
This figure shows the genetic relationships among these viruses, where all the WA viruses are closely related. Given this shared ancestry pattern, it looks like the large majority of current cases in WA derive from a single introduction event. nextstrain.org/ncov?label=cla… 3/9

Thanks to @seattleflustudy and @UWVirology, we have new genomic data on the spread of #COVID19 in Washington State with 2 new #SARSCoV2 genomes sequenced today, bringing the total number of WA genomes to five. 1/8
Four of these five genomes are all part of a single cluster that appears to descend from the initial WA1 case identified in mid-Jan, including the case in Snohomish as well as two cases from King County. 2/8 nextstrain.org/ncov?branchLab…
This directly suggests that the transmission chain initiated in mid-Jan by case WA1 in Snohomish is responsible for at least a portion of the cases appearing in Seattle. 3/8

Thanks to rapid global data sharing of #SARSCoV2 genomic data via gisaid.org, we can reconstruct large and small scale patterns of #COVID19 spread. This is a thread discussing this intersection of large and small. 1/7
At this point, a decent fraction (10/43) of sequenced viruses sampled after Feb 1 belong to a particular genetic lineage. This lineage has mutations unique to it that differentiate it from other #SARSCoV2 lineages. nextstrain.org/ncov?c=gt-nuc_… 2/7
This lineage contains viruses sampled from Germany, Switzerland, Finland, Italy, Brazil and Mexico. The Italian sample is from Lombardy, further suggesting this lineage is responsible for a sizable portion of the Italian epidemic. 3/7

Shen Yongyi and Xiao Lihua at the South China Agricultural University, Yang Ruiyu at the Chinese Academy of Military Sciences, Chen Wu at the Guangzhou Zoo Research Department and colleagues have shared data via GISAID from a pangolin-associated SARS-like coronavirus. 1/4
This virus pangolin/Guangdong/1/2020 groups closely with pangolin/Guangdong/P2S/2019 released yesterday by researchers at the Beijing Institute of Microbiology and Epidemiology and the University of Hong Kong, differing only by ~60 bp and each 93% identical to #COVID19. 2/4
It seems possible that both research groups may have been working from the same animals seized in Guangdong. Thanks to open data sharing by both groups it's possible to connect these two stories. 3/4

[THREAD] China Coronavirus Outbreak
A deadly virus is spreading from Asia, affecting hundreds of people and resulting in dozens of deaths, in what may become a gloabal health epidemic. This thread contains news about the outbreak.
#Coronavirus #WuhanOutbreak #ChinaVirus #WarWatch
On Dec 30, 2019, Chinese authorities confirmed cases of pneumonia of unknown cause in Wuhan, Hubei Province. A team of national experts was sent to carry out detection tests. Patients at a local seafood market were put in quarantine.
#Coronavirus #WuhanOutbreak #ChinaVirus
Liu Youning, a professor of epidemiology and respiratory medicine, told the Global Times that the #coronavirus found in #Wuhan appears to be far less serious than the virus that caused the severe acute respiratory syndrome (#SARS) or the Middle East respiratory syndrome (#MERS).

HALLOWEEN IN WALES:
A THREAD 🎃🏴󠁧󠁢󠁷󠁬󠁳󠁿

"All Hallows Eve is by the Welsh called ‘Nos Calan Gaeaf,’ meaning the first night of winter. It is one of the three nights for spirits, upon which ghosts walk and fairies are abroad." 1/

(I'll be updating this thread daily as we count down to Halloween, and all quotes are courtesy of the great Wirt Sikes 1880 unless otherwise stated)
On #Halloween (Nos Calan Gaeaf) in Wales: "ghosts walk, fairies are abroad, mysterious influences are in the air, strange sights are seen, and in short goblins of every sort are to be with special freedom encountered."
