The US Centers for Disease Control and Prevention issued a statement criticizing the quarantine efforts taken on the Diamond Princess cruise ship.
“We commend the extraordinary efforts by the Government of Japan to institute quarantine measures onboard the Diamond Princess. While the quarantine potentially conferred a significant public health benefit in slowing transmission, CDC’s assessment is that it may not have been sufficient to prevent transmission among individuals on the ship. CDC believes the rate of new infections on board, especially among those without symptoms, represents an ongoing risk. Therefore, to protect the health of the American public, all passengers and crew of the ship have been placed under travel restrictions, preventing them from returning to the United States for at least 14 days after they had left the Diamond Princess," the CDC said in the statement.
The CDC noted that there are still more than 100 US citizens on board the ship or in hospitals in Japan. Due to their high-risk exposure, there is the potential for additional novel coronavirus cases to occur and the remaining passengers who disembark from the ship will be subject to a 14-day quarantine.
