The death toll from the Wuhan coronavirus now stands at 80, with almost 2,800 cases confirmed across China, as the country initiates emergency procedures to try and rein in the pathogen's global spread.
Making that task more difficult is the fact that the virus can be spread before any symptoms appear, Chinese health authorities said Sunday, meaning carriers may not realize they are infected before they transmit the virus to others.
Across China, 15 cities with a combined population of over 57 million people -- more than the entire population of South Korea -- have been placed under full or partial lockdown.
