On Oct 1, 2025, GISAID informed us that they had ended updates to the flat file of SARS-CoV-2 genomic sequences and associated metadata that we had used to update Nextstrain analyses since Feb 2020. GISAID's stated rationale was that their "resources are limited". 1/5

Absolutely thrilled to announce the launch of ARTIC2 - a £5.5M 5 year project funded by @wellcometrust.bsky.social to build on the ARTIC approach of low-cost, globally accessible genome sequencing for surveillance of outbreaks, epidemics and endemic diseases: www.birmingham.ac.uk/news/2025/am...
Ambitious project to develop low-cost genome sequencing for pathogens known and unknown - University of Birmingham
Project will build on research that helped diagnostic labs to adopt sequencing capacity for COVID-19 and permit characterisation of future infectious threats

1/ How has H5N1 affected this year’s flu season in Seattle? Despite ongoing outbreaks in birds & cattle nationally, we detected zero H5N1 cases in 675 influenza A-positive specimens tested at UW Medicine.

I’m so tired of hearing Rubio & other rightwingers now claiming that if you’re on a green card you’re a ‘guest’ in this country. BS. You’re a lawful permanent resident. The clue is in the name. If someone is a permanent resident in your home, are they the same as the guests who come and go? Come on.

Excited to be involved in this study led by Helen Chu as part of the CDC's CHARM network tracking the spread of respiratory viruses across the US.
The 5-yr pandemic-preparedness project will trace how #flu, #COVID_19, #RSV and other respiratory viruses spread in communities, and catalog circulating strains.
Dr. Helen Chu of @uwmedicine.bsky.social will lead the study. tinyurl.com/39tmkvyk
