Now online in EID: Household Transmission of Enterovirus D68, Washington and Oregon, United States, 2022–2024. doi.org/10.3201/eid3... We used data from the CASCADIA cohort in WA and OR, combining prospective household surveillance with viral sequencing. Some key findings:

Efforts are underway @uwmedicine.bsky.social to streamline Western Blot genital herpes test interpretation. Scientific American's @sciam.bsky.social Lauren Schneider spoke with virus experts Alex Greninger & Pavitra Roychoudhury
Why we need better genital herpes tests
The best blood test for herpes is only available at a single lab. What would it take for that to change?

“[P]utting data into GISAID is like dropping it in a mail slot in an unmarked building,” says @colincarlson.bsky.social. “It’s wonderful that there’s so much cool stuff in that building. It would be great if we knew who owned it, or who paid for it, or what they plan to do with it.” #IDsky 🧪
Fresh conflicts erupt around giant database for flu and COVID-19 sequences
Critics say “autocratic” behavior by GISAID could hamper response to a future pandemic

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...

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
