The move comes as a result of growing concerns regarding the virus in China, as well as recently implemented travel restrictions by countries including the UK and US.
Between 5-31 January, guests who have visited mainland China, Hong Kong, or Macau within 10 days prior to embarkation will be required to submit proof of a negative medically supervised PCR test taken within 48 hours prior to the beginning of travel to the port.
This also applies to guests transiting through an airport in one of the countries within 10 days prior to embarkation.
