On the morning of 2020.04.30, the senior doctor on "Norwegian Gem" was found dead in his cabin. NCL claimed that he died of a heart attack in his sleep, though crew members stated that he was being treated for pneumonia and had not been tested for the virus. Also, according to crew members, a nurse who had worked closely with the doctor had reportedly tested positive for the virus after being removed from the ship. There was concern among crew members that NCL had been hiding evidence of the virus on board "Norwegian Gem", which may become an issue if NCL carries out plans to combine crews from different ships together before sailing them back home.
