Holland America is the grand-tour classic — longer itineraries, older passengers, world cruises — and currently the most instructive fleet in the outbreak data: Rotterdam and Eurodam logged four CDC-reported outbreaks each across 2024–2026, with Zuiderdam, Volendam and Koningsdam also appearing. Longer voyages mean longer exposure windows and more vulnerable passengers, not necessarily worse ships — HAL's inspection scores remain high. If you are sailing HAL with a chronic condition, the pre-cruise doctor check below is genuinely worth thirty minutes.
HAL's grand voyages are cruising's endurance events — weeks aboard, older guests, remote segments — and its outbreak history is the honest backdrop: Rotterdam and Eurodam lead the CDC log. That is a reason for discipline, not avoidance: wash with soap before every meal, skip the buffet during any reported illness, report symptoms early rather than riding them out in the cabin. Before a voyage over three weeks, a structured medical review is not optional caution; it is the sensible entry ticket.

Two things are worth doing in the fortnight before boarding: check the pre-cruise health guidance — especially if you are pregnant, manage a chronic condition, or the line's terms ask for a fit-to-travel confirmation — and check the live conditions in your ports. Talk to a doctor before you sail →
Koningsdam currently holds the fleet's best CDC score in this index: 100/100, inspected 2026-01-06. 2 Holland America ships hold a current EU SHIPSAN grade A.
No Holland America ships appear in the CDC's 2024–2026 gastrointestinal outbreak log. Note the log covers ships under CDC jurisdiction; European-waters outbreaks are handled by national port health authorities.
Like most major lines, Holland America requires a doctor's confirmation for defined situations — typically pregnancy (not carried when entering the 24th week by voyage end), oxygen or dialysis use, and recent major surgery or cardiac events; exact rules are in the line's terms. A Mobi Doctor physician can assess you online and provide documentation where clinically appropriate.
