The death toll from corona virus reaches to 563 from 73 as experts stepped up efforts to find a vaccine for a disease that has shut down Chinese cities and forced thousands of others into quarantine around the world. Central China’s Hubei has been almost sealed off for nearly two weeks with its railway stations and airports shut and roads blocked. The flu-like virus was first identified in Hubei’s provincial capital of Wuhan and is believed to have originated at a seafood market in the city.
