If this is the case, a nasopharyngeal swab test (RT-PCR molecular test) will be required on the day of embarkation. This procedure will be mandatory for guests over the age of 6. The costs of the test will be borne entirely by Costa. The updated classification of countries at risk is available on the Costa website. In addition, under the Italian Presidential Decree of December 3, 2020, provisions have been approved for travel to Italy, depending on the country of origin. The decree classifies countries according to three tiers, corresponding to three risk scenarios, for which different actions are required in order to enter Italian territory. For more information and updates on this subject please consult and refer to the Italian Ministry of Health website.
