An adult passenger suffering from measles who travelled on a Tallink ro-pax from Finland has sparked a health warning.
Passengers on the 58,000-gt Silja Serenade (built 1990) between 1 and 3 February have been advised to check they have been vaccinated, YLE reported.
The ferry serves the Helsinki to Stockholm route.
A passenger was diagnosed with measles on Monday and is believed to have been infected in southern Finland, according to the National Institute for Health and Welfare (THL).
