Updating the story from last weekend when seven passengers from Fred Olsen's Black Watch were taken to the hospital in Stockholm:
Two of the passengers have now tested positive for the legionella bacteria, legionnaires disease. Swedish officials said the water samples taken from the ship have tested negative for the bacteria. That would tend to indicate that the passengers contracted the disease somewhere ashore, and the cruise ship was not the source. Nonetheless, the ship is being thoroughly disinfected before the next sailing.
The cruise line has refunded passengers 25% of their cruise fare for the cruise which was terminated two days early. Black Watch is now back in England being "deep cleaned" and preparing for its next cruise on Wednesday.
