I have always taken extra RX medications and some OTC meds "just in case." It seems to me that some of the mentioned items may not be necessary. My husband and brother-in-law both tested positive during our Panama Canal cruise in Oct 2021. We were on the Nieuw Amsterdam and the treatment and support was exemplary. They were both given IV monoclonal antibodies the morning after the positive tests. Any meds needed to cope with symptoms were provided and the support team did everything possible to make the isolation as pleasant as possible. At the end of the cruise we were transported to a 4 star hotel until the isolation period was completed. The liaison group continued to check on our needs and also arranged transportation to the airport. We were not charged for any of the above. They were willing to cover any costs for changing flights, etc that were not covered by travel insurance. We were given future cruise credit for each day in isolation onboard. They went above and beyond any expectations and we felt safe coping with Covid under their direction.
I am concerned that passengers who test and treat themselves without the medical center may not properly isolate, thus exposing other passengers. I understand wanting to have anything you may need, but our experience with the medical center leads to confidence that they can and will handle anything that is needed.
