Snapshot report This is an archived daily snapshot reflecting the cluster state as reported on 9 May 2026. Case counts have evolved since publication. An earlier version of this report incorrectly described a "CDC walks back US passenger quarantine" event; that framing was inaccurate and has been removed, as 18 American passengers were ultimately repatriated to UNMC Nebraska on 11 May.
