WUHAN, China — The Chinese government scrambled to contain not only the coronavirus epidemic but also growing expressions of public fury over the management of the crisis as the death toll rose on Tuesday to at least 106.

China’s National Immigration Administration on Tuesday encouraged Chinese citizens to reconsider the timing of overseas travel to curtail the spread of the coronavirus, it said on its WeChat account. That came as the United States Centers for Disease Control and Prevention urged American citizens to avoid nonessential travel to China.

Premier Li Keqiang, the prime minister of the Chinese government, flew on Monday into Wuhan, the epicenter of the outbreak, to show support for medical workers and to pledge needed medical supplies — only to be mocked online for leading workers in an encouraging cheer.
