SeaDream 1: five passengers test positive for Covid-19 on Caribbean cruise ship
"The SeaDream is carrying 53 passengers and 66 crew, with the majority of passengers hailing from the US, according to Sue Bryant, a cruise ship reporter who is aboard the ship.
She told the Associated Press that one passenger became sick on Wednesday and forced the ship to turn back to Barbados, where it had departed from on Saturday. However, the ship had yet to dock in Barbados as local authorities tested those on board. The captain announced that at least five passengers had tested positive, Bryant said."
As I have said before, until we come up with an international protocol for how we deal with the Covid positive but not ill patient who is a passenger on board, cruise ships will remain moored off-shore for the foreseeable future.
