Route signals included in the dataset
MV Hondius and southern South America context: WHO's report describes the first probable case boarding on 1 April after extended travel in Argentina, Chile, and Uruguay. WHO's working hypothesis points toward probable environmental exposure before boarding, especially in Argentina. That is why the route story begins with land-based exposure context rather than an unexplained ocean origin.
St Helena, Ascension, and Johannesburg: these locations are part of the clinical and medical movement chain. Case 2 went ashore at St Helena with symptoms and later died in Johannesburg. Case 3 was medically evacuated and hospitalized in Johannesburg. These markers describe medical response and severe disease connected to the ship event, not South African community spread.
Cabo Verde and Tenerife: WHO reporting and later coverage describe evacuation and response activity before the vessel reached the Canary Islands area. Tenerife appears as a response hub where passengers were screened and onward travel or isolation plans entered public reporting. A route through Tenerife is therefore relevant to event management, but the meaning depends on the destination and source.
Zurich and the Netherlands: these locations connect to confirmed case evidence in the WHO baseline. Zurich is tied to a Swiss passenger with PCR positivity. The Netherlands is tied to confirmed crew cases and medical evacuation context. These are stronger signals than broad media-only route mentions.
France and the United States: later reputable reporting described positive tests in evacuated passengers. Those entries are important route matches, but they remain labeled as reported imported cases unless official local sources publish the same update. They are not evidence of broad local spread.
United Kingdom, Spain, Canada, Ireland, Japan, Australia, Turkey, and broader Europe: these entries have different meanings. Some are isolation or quarantine reporting. Some are passenger nationality signals. Some are media-only leads. A match to one of these places requires the status label before any risk conclusion.
