Additional cases of the H1N1 virus also known as swine flu have been confirmed among five cruise ship crewmembers.
An official statement from Holland America Line confirms that the crewmembers, onboard Zaandam's May 29 Alaska sailing, tested positive for H1N1 in a shore-side lab operated by the Centers for Disease Control and Prevention. They were isolated in their cabins immediately after reporting initial cold and flu-like symptoms and treated. All have recovered.
No passengers aboard the cruise, which ended June 5 in Seattle, were identified with the virus. Also, there are no affected crewmembers or guests identified on the current sailing.
The statement also says that guests on the current sailing were notified of the outbreak, and that nobody elected not to sail. As a precaution, a special cleaning chemical proven effective in killing the virus was used in high traffic areas onboard.
