01
The current analyst view of this scope, at increasing levels of depth.
Routine surveillance. No novel emergence signals.
SARS-CoV-2 variant monitoring continues with JN.1 sublineages dominating globally. No signals of novel coronavirus emergence from animal reservoirs. Wastewater surveillance in 14 countries shows stable or declining viral loads. The system tracks immune escape mutations in spike RBD and monitors bat and pangolin coronavirus discovery papers for recombination signals.
