An outbreak of Covid-19 has spread further on a Greek-owned passenger ship carrying hundreds of quarantined seafarers and shiprepair workers on board.

Another twenty out of a total of 383 people on ANEK Lines’ 38,300-gt El. Venizelos (built 1992) have tested positive for the disease, Greek health ministry officials said on 1 April.

That is twice the number of cases authorities announced on 31 March, when they first reported the case.
