We always travel with test kits. Our recent Apex cruise we tested half way through in case asymptomatic & when I had a cough. Negative.
We’ve both been unwell since we’ve been home (2 weeks) temperatures, cough, sore throat. Still negative.
Whatever we’ve brought home isn’t covid. Then we remember that we are usually unwell after a cruise. Unsurprising given the lifts, coaches etc.
