Hong Kong has announced plans to slash cross-border travel between the city and mainland China as the new coronavirus continues to spread.

More than 100 people have now died in China, with confirmed infections surging to more than 4,500. High-speed trains and ferries that cross the border will be suspended from Thursday, Hong Kong leader Carrie Lam announced. She wore a face mask.

The virus has spread across China and to at least 16 countries globally. _______ (1) Monday, Germany and Japan confirmed that they had cases involving people who had not travelled to China but caught the virus from someone who had. This had previously been seen only in Vietnam, which borders China and where someone was infected _______ (2) his father who had travelled from Wuhan, the city at the epicentre of the outbreak. On Monday, authorities in Beijing confirmed that a 50-year-old man had died - the first fatality in the Chinese capital. The new coronavirus is thought to have emerged from illegally traded wildlife at a seafood market in Wuhan.

These latest cases in Japan and Germany suggest that anyone coming into close contact with another infected person could catch it. It's thought people with symptoms, such as a cough and fever, will be the most contagious. But experts haven't ruled out that people with no obvious signs of infection could also pose a risk. And it can take more than a week for a person to develop symptoms. The advice is to avoid close contact with people who are infected - that means keeping enough distance to avoid breathing air or touching surfaces contaminated with respiratory droplets from others carrying and shedding the virus.
