I am not from the US so I think it is worth noting that the vast majority of your neighbouring countries think that the US is opening too quickly. I am not saying this to spark an argument but to say that it’s all well and good to be able to cruise from US ports but there may not be a lot of ports that will accept the ships due to the risk that it could be brought into their ports with the ship and its passengers.
(I was on the Wonder when it was turned away from Colombia and Panama.)
I am from the US, and you are absolutely correct. We're opening too quickly, and we will have a spike in infections that will follow as a result. As it is, our federal government revised what they thought the death total through August 4th up from 60K to 100K. Pretty soon, that will revised upwards again. The internal number out of the White House of daily deaths now is that we're at 3,000 dead per day by June 1st. That would get us to roughly 150,000 deaths by July 4th.
Our only hope is the summer gives us a little bit of a break, but other than that, as we spike back up, the hospitals will fill up again, and not just in NY, NJ, WA and other cities, but in rural areas as the virus continues to spread.
I think that the states will have a very difficult time getting their citizens back in again after this first round of the virus, so we'll see businesses defying newly issued "stay at home" orders....and a certain level of chaos will reign. And then, all on their own, as many Americans who can stay home....will. Here in the US, there is no federal response, and with states doing whatever they want, we are clearly determined to make this so much more difficult than it needed to be.
And all of that to say.....highly doubt that Carnival is cruising by August 1st. And if they're crazy enough to do so, after seeing what is going to happen here for the next three months, no island or country would allow a ship from the US to dock. I wonder how many ventilators they can fit in a cruise ship's medical unit?
