MS Hamburg is a 15,000-ton, 420 passenger, luxury cruise ship owned by the Conti Group and is now operated by Plantours Kreuzfahrten.

[7] On 5 May 2015, a fishing net became tangled in the ship's propeller off the South East coast of England.

[9][10] On 26 November 2021, the MS Hamburg arrived in the Port of Buenos Aires coming from Cape Verde.

The port was operating under a new, more restrictive, protocol for ships arriving from Africa, due to the emergence of the SARS-CoV-2 Omicron variant.

The Argentine authorities, however, denied the mistake, stating that all the passengers in the ship were tested for Covid and that the results returned negative.
