Key Aspects:
- A gastrointestinal illness outbreak was confirmed aboard National Geographic Sea Bird on July 12.
- 18 of the 62 onboard passengers were affected with symptoms including vomiting and abdominal pain, although the cause is unknown.
- This is the third outbreak for National Geographic Sea Bird in 2026.
Another outbreak of gastrointestinal illness was confirmed aboard National Geographic Sea Bird during its five-day, one-way Alaska cruise. Passengers first reported symptoms on July 12, with the predominant symptoms reported being vomiting and abdominal pain.
According to a report by the US Centers for Disease Control and Prevention (CDC), 18 of the 62 passengers onboard were affected, accounting for 29% of total passengers. No crew members reported any symptoms.
The outbreak was reported to the CDC’s Vessel Sanitation Program (VSP), which monitors and tracks outbreaks on ships visiting US ports.
Although the underlying cause of this outbreak is unknown, the most common cause of gastrointestinal illness, particularly on cruise ships, is norovirus, a highly contagious virus that can spread through physical contact between people as well as through food and touched surfaces.
Symptoms of norovirus typically spring up 12 to 48 hours after exposure and include vomiting, diarrhea, nausea, and stomach pain.
When the outbreak began, Lindblad Expeditions, which operates National Geographic Cruises, sprang into action, implementing increased cleaning and disinfection procedures and isolating affected passengers.
Onboard medical professionals also collected stool samples from ill guests for testing and consulted with VSP to optimize their cleaning and sanitation procedures. The CDC continues to monitor the situation remotely and is reviewing the ship’s outbreak response procedures.

The voyage, which departed from Sitka in Alaska on July 10, hit some of the most popular spots in the region, stopping at Baranof Island on July 11, followed by Icy Strait Point and Inian Islands on July 12, then moved on to Haines on July 13, and Tracy Arm Fjord on July 14, before arriving in Juneau on July 15.
The 630 gross ton cruise ship has since departed Juneau on another five-day, one-way Alaska sailing, stopping in Glacier Bay, Summer Strait, Wrangell, and Misty Fjords, before arriving in Ketchikan on July 20, 2026. No outbreak has been reported on the current sailing.
Sea Bird’s Rough Final Season
This news comes just weeks after Cruise Hive reported on two separate norovirus outbreaks aboard National Geographic Sea Bird in May and June 2026. Those outbreaks prompted an expanded response from the Vessel Sanitation Program, which even sent investigators onboard the ship to physically assess the situation.
Despite the increased pressure from these investigations, and passing an October 2025 VSP Cruise Ship Inspection with a score of 96, where a score of 86 is considered satisfactory, it seems that the ship has been hit with a stroke of bad luck when it comes to illness outbreaks.
Of the eight illness outbreaks aboard cruise ships in 2026 so far, National Geographic Sea Bird accounts for three of them, an unfortunate 37.5% of all 2026 cruise ship outbreaks.
The ship, originally built in 1982 as Majestic Explorer, operated by Lindblad Expeditions as Sea Bird since 1988 and partnered with National Geographic since 2007, is sailing into her final season. After over four decades of sailing, she is set to retire in 2027.
