12:08 pm: Passengers to begin disembarkation from quarantined cruise ship in Japan
Passengers and crew members on board the Diamond Princess cruise ship who are not taking government repatriation flights will begin the process of disembarking, ship operator Princess Cruises said, citing the Japanese health ministry.

5:48 pm: CDC places travel restrictions on Princess Cruise passengers
The CDC said it is prohibiting any passengers or crew from the Princess Cruise ship that was quarantined off the coast of Japan from returning to the U.S. for at least 14 days. There are still more than 100 of the original 3,700 people still aboard the Diamond Princess ship or in hospitals in Japan.
They will need to wait 14 days after disembarking from the ship — without showing symptoms or testing positive for COVID-19 — before they will be allowed to fly back to the U.S., the CDC said.
"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," the agency said. "CDC believes the rate of new infections on board, especially among those without symptoms, represents an ongoing risk." — Kopecki
5:26 pm: Too early to tell whether the outbreak is slowing in China
China may be reporting fewer new cases of coronavirus and fewer COVID-19 deaths, but it does not mean the country's outbreak is slowing, immunologist Anthony Fauci told CNBC on Tuesday.
"I think we need to give it a few more days to determine if that's real or if that's the variability that you generally see," Fauci, a member of President Donald Trump's coronavirus task force, said on "Closing Bell." Fauci, who is the director of the National Institute of Allergy and Infectious Disease, was referencing reports Tuesday that the number of new daily cases in China fell below 2,000 for the first time since Jan. 30.
Chinese officials also reported 98 deaths, the first time the daily toll was below 100 since Feb. 11. — Stankiewicz
