Authorities in Curacao have boarded a ship that arrived under quarantine to start vaccinating people to prevent a measles outbreak.
Health officials said only those who already have been vaccinated or have previously had measles will be free to leave the 440ft ship Freewinds, which belongs to the Church of Scientology.
Curacao epidemiologist Izzy Gerstenbluth told the Associated Press that a small team is assessing more than 300 people aboard the ship, and that the process might take more than a day.
“We will go on board and do our job,” he said, adding that authorities have an international obligation to avoid spreading the disease.
“If we allow that to happen, measles spreads in places where the risk of severe complications is much bigger, especially when we’re talking about poor countries where people have a lower level of resistance.”
Authorities are concerned that people aboard the ship might have been exposed after a female crew member was diagnosed with measles after coming back from Europe.
Dr Gerstenbluth said she arrived on the Dutch Caribbean island of Curacao on April 17 and visited a doctor on April 22 for cold symptoms.
A blood sample was taken and sent to nearby Aruba, where officials confirmed it was measles on April 29, a day after the ship had departed for St Lucia. Curacao health officials then alerted authorities in St Lucia.
The Freewinds was under quarantine in St Lucia earlier this week before it returned to its home port of Curacao early on Saturday.
Dr Gerstenbluth said it would be easy to spread the disease given that it is a small ship.
“This is what happens when we don’t vaccinate,” he said.
Symptoms include a runny nose, fever and a red-spotted rash. Most people recover, but measles can lead to pneumonia, brain swelling and even death in some cases.
Measles has affected more than 700 people in 22 US states this year, with federal officials saying the resurgence is driven by misinformation about vaccines.
According to the Church of Scientology website, the ship is the home of “a religious retreat ministering the most advanced level of spiritual counselling”. It says religious conventions and seminars are also held aboard.
