═══════════════════════════════════════════ WHAT TO WATCH (NEXT 48–72 HRS) ═══════════════════════════════════════════

TIER 1 — EXECUTION RISK:
├── Tenerife evacuation completes by Mon
│   (weather closes Tuesday)
├── No onshore-resident exposure events
├── US biocontainment charter → Omaha
└── Sustained H2H signal aboard ship
    (still the only thing that changes the
    epidemiological picture)

TIER 2 — INCUBATION TAIL:
├── SH disembarkees across ~12 countries
│   (window still open through mid-May)
├── KLM flight attendant follow-up swabs
├── Tristan da Cunha case workup
└── 42-day home monitoring of returnees

TIER 3 — POLITICAL/COMMS:
├── Spain — Sánchez/Clavijo fallout
├── AR Malbrán Institute rodent results
├── Argentina-WHO data sharing tension
└── Whether crew remain on Hondius for
    onward sail to Netherlands

Bottom line (May 10): Endgame begins today. Ship anchored off Tenerife at dawn; Tedros personally on-island. Repatriation runs Sunday–Monday with a hard weather deadline Tuesday. The narrative has fully consolidated around "contained zoonotic cluster, not Covid-2.0" — Tedros writing personally to Tenerife residents to say so, CDC not testing asymptomatic Americans, HHS calling broader US risk "extremely low." Zero of 17 Americans positive. The KLM-attendant scare resolved negative. The remaining real risk is operational, not epidemiological — getting 147 people off a ship in a closing weather window without seeding onshore community exposure. Watch for any disembark hiccup or weather slip past Tuesday.
