The death toll from the Wuhan coronavirus stands at about 80, with almost 2,800 cases confirmed across China. The country has initiated emergency procedures to try and rein in the pathogen’s global spread.
The virus can be spread before any symptoms appear. Carriers of the virus 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 lockdown.
Wuhan itself has been effectively quarantined, with all routes in and out of the city closed or highly regulated.
The Wuhan virus was first identified in December. Chinese and international scientists have been studying it intensely, tracking its origin and working on a vaccine.
