The director of a hospital in Wuhan, China, the epicenter of the novel coronavirus outbreak, died after contracting the virus Tuesday.
Liu Zhiming, age 51, was a neurosurgeon and director of the Wuchang Hospital in Wuhan, according to the Wuhan health commission.
A new study by the Chinese Center for Disease Control and Prevention, an agency of the National Health Commission, found that more than 80% of people who contracted the newly discovered virus -- known officially as COVID-19 -- had mild symptoms and recovered, while 14% of the cases studied included severe symptoms, like pneumonia and shortness of breath. About 5% of patients had critical symptoms, such as organ and respiratory failure and septic shock.
