WHO recommends a 42-day active monitoring window for known close-contact exposures — including the MV Hondius repatriated passengers — because that window covers more than 99% of historical Andes virus incubation intervals.
This answer is based on WHO Disease Outbreak News (DON599, DON600), the CDC's hantavirus clinical overview, ECDC technical assessments, and peer-reviewed Andes virus literature including the Epuyén cluster studies.

WHO's Disease Outbreak News DON600 (May 8) and the Director-General's May 9 message to the people of Tenerife are the most up-to-date official sources. Hanta Hub aggregates these on the main tracker.
