We just got off the Carnival Horizion on April 24. Myself and my wife contracted COVID-19 while on board, we are assuming it was on the last 2 days of the cruise.
I had initially thought the wife had turned down the air, and had developed running nose and coughing. Then on Saturday it got worse, diaherra and body aches and fatigue. Wife got it on Sunday.
Just passing the information on to others. We both were vaccinated and had tested negative before the cruise.
