BEIJING – The number of confirmed cases of the new virus has risen again in China while fatalities increased to 722 on Saturday, as the ruling Communist Party faced anger and recriminations from the public over the death of a doctor who was threatened by police after trying to sound the alarm about the disease over a month ago. The government announced that another 3,399 people had been diagnosed over the last 24 hours, reversing two days of declines, and raising the total accumulated number of cases on the mainland to 34,546. Cruise ship passengers faced more woe as Japan reported three more cases for a total of 64 on one quarantined vessel and turned away another.
