I take no pleasure either, however I'm frustrated that it was clear that this was going to happen, but nobody else seemed to acknowledge it. Thousands of people in close contact just now isn't a great idea, let alone moving them all from country to country.
Cunard must be hugely affected. They have lots of older passengers, who are being advised not to go on cruise ships (or anywhere else now). I'm amazed they've managed to keep sailing this long.
The cruise industry provides employment and enjoyment, but also has a huge number of problems now due to constant growth over the past couple of decades (thousands of extremely large polluting ships).
The majority of businesses will be affected, lots of them very seriously. Lots of us are going to have to lose our jobs, or take unpaid leave, hopefully temporarily...
