Singapore has temporarily suspended crew changes and crew vaccinations for seafarers with recent travel history to several African countries over fears about exposure to a potentially more contagious variant of the Covid-19 virus.

The countries affected are Botswana, Eswatini, Lesotho, Mozambique, Namibia, South Africa and Zimbabwe, the Maritime Port Authority (MPA) said in a port circular.

This includes sign-on crew travelling to Singapore by flight as well as sign-off crew from vessels that have called at the seven countries within the last 14 days, as well as those crew have transited those same countries on their connecting flights to Singapore.
