Snapshot report This is an archived daily snapshot reflecting the cluster state as reported on 10 May 2026. An earlier version of this report contained two factual errors: a "Singapore residents test negative" event that never occurred, and a "CDC walks back US quarantine plan" framing that was inaccurate. Both have been removed in this revised version (12 May 2026). See the corrections log for full editorial history, and the MV Hondius outbreak file for current live state.

What happened on 10 May

The MV Hondius arrived at Granadilla port, Tenerife, at 05:30 WET, ending the maritime exposure phase of the cluster. Spanish authorities executed the prevention plan that Health Minister Mónica García had earlier characterised as unprecedented: disembarkation by speedboat directly to Tenerife airport, with no contact between passengers and island residents. WHO Director-General Tedros Adhanom Ghebreyesus led the WHO response team on site.

By late 10 May, seven evacuation flights had taken off, transporting 94 passengers to six European countries and Canada. Separately, British paratroopers from 16 Air Assault Brigade airdropped 3,300 kg of medical supplies onto Tristan da Cunha, where one resident, a former MV Hondius passenger, was suspected of infection. Spain transitioned from monitoring to active status with the docking.
