The coronavirus outbreak is hitting a peak in China this month and may be over by April, the government's senior medical adviser said on Tuesday, in the latest assessment of an epidemic that has rattled the world.

In an interview, Zhong Nanshan, an 83-year-old epidemiologist who won fame for combating the SARS epidemic in 2003, shed tears about Dr. Li Wenliang, who died last week after being reprimanded for raising the alarm.

But Zhong was optimistic the new outbreak would soon slow, with the number of new cases already declining in some places.
