Five crew members on a cruise ship which passed through Alaska last week tested positive for the swine flu virus, state health officials have confirmed.
A spokesman for the Alaska Division of Public Health yesterday confirmed five crew on board Holland America's Zaandam were diagnosed with the A(H1N1) virus after tests carried out in the port city of Ketchikan.
A statement from the ship's operators Holland America, owned by Carnival Corp, said the ship was on a seven-day trip which ended in Seattle on June 5.
Affected crew members were immediately isolated in their cabins after showing initial flu-like symptoms, the statement said. All affected crew were treated and subsequently recovered, it added.
No passengers aboard the cruise had been diagnosed with the virus, the statement added.
The company said all passengers aboard a current cruise by the Zaandam, which departed Seattle on June 5, had been made aware of the incident.
