BEIJING, CHINA - FEBRUARY 19: Chinese men wear protective masks in a residential neighbourhood on February 19, 2020 in Beijing, China. The number of cases of the deadly new coronavirus COVID-19 rose to more than 58000 in mainland China Wednesday, in what the World Health Organization (WHO) has declared a global public health emergency. China continued to lock down the city of Wuhan in an effort to contain the spread of the pneumonia-like disease which medicals experts have confirmed can be passed from human to human. In an unprecedented move, Chinese authorities have maintained and in some cases tightened the travel restrictions on the city which is the epicentre of the virus and also in municipalities in other parts of the country affecting tens of millions of people. The number of those who have died from the virus in China climbed to over 2000 on Wednesday mostly in Hubei province, and cases have been reported in other countries including the United States, Canada, Australia, Japan, South Korea, India, the United Kingdom, Germany, France and several others. The World Health Organization has warned all governments to be on alert and screening has been stepped up at airports around the world. Some countries, including the United States, have put restrictions on Chinese travellers entering and advised their citizens against travel to China. (Photo by Kevin Frayer/Getty Images)
