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.
The CDC log shows 11 gastrointestinal outbreaks on Holland America ships in 2024–2026: Rotterdam (2025, Norovirus), Eurodam (2025, Norovirus), Zuiderdam (2025, Unknown), Rotterdam (2025, Norovirus), Eurodam (2025, Norovirus), Rotterdam (2025, Norovirus), Volendam (2025, Norovirus), Eurodam (2024, Norovirus), Rotterdam (2024, Norovirus), Zuiderdam (2024, Norovirus), Koningsdam (2024, Norovirus). Outbreak counts reflect itinerary length and passenger profile as much as ship standards — see the full log for context.
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.
