BEIJING, CHINA - FEBRUARY 11: A Chinese woman wears plastic wrap, bags and a protective mask as she walks in a residential neighbourhood on February 11, 2020 in Beijing, China. The number of cases of a deadly new coronavirus rose to more than 42000 in mainland China Tuesday, days after the World Health Organization (WHO) declared the outbreak 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 put travel restrictions on the city which is the epicentre of the virus and 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 1000 on Tuesday, 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)
