Coronavirus Death Toll Passes 900 As More Americans Diagnosed On Quarantined Cruise Ship

China confirmed a rise in the number of new coronavirus cases on Monday, quashing hopes after several days of declining infection rates that strict control measures could be paying off. The death toll from the new virus had jumped to 908 by Monday morning, more than were killed during the SARS virus outbreak in 2003.

The number of confirmed infections in mainland China rose 15% Sunday to at least 40,171. More than 300 cases have been confirmed outside China, including 12 in the U.S., and global health officials have warned that could be just "the tip of the iceberg" as they learn more about how easily the disease spreads.

Dozens of new cases were confirmed Monday on a quarantined cruise ship in Yokohama, Japan, meanwhile, including more Americans. The number of passengers already removed or soon to be removed from the Diamond Princess for treatment in Japanese hospitals stood at 136 Monday. That includes at least 23 American passengers, 11 of whom were among the 66 new cases confirmed Monday. Most of the 3,711 passengers and crew remained under isolation orders on the ship.

The Chinese government's efforts to silence people who tried to raise the alarm about the outbreak early on — and allegedly ongoing efforts to stop people reporting on it — have created a mounting backlash on the country's heavily-censored social media.
