Why surveillance is important? 4 years ago we predicted a CHIKV outbreak by detecting its silent circulation (lnkd.in/gx7-4ZeQ). Today, the team @mauriciolnogueira.bsky.social provided a genomic and clinical time map of the massive CHIKV outbreak of 2024 in the area. #FAMERP #SBV #ASTMH #UTMB #ACAV

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

I want to spell this out in case the implications aren't clear:

This means all public tools/webapps of GISAID data (all the ones you've been used to seeing thru the pandemic, as far as we can tell) are prohibited.

The file allowed this. Cut that - cut off all tools the public & others were using.
