The deadly coronavirus outbreak that has spread from China does not yet constitute a "pandemic", the World Health Organization (WHO) has said.

At least 427 people have died with more than 20,000 confirmed cases around the world, most of them in China.

More than two dozen nations have reported cases but, so far, no confirmations have been made across Africa or Latin America.

On Tuesday, three more Asian countries - Singapore, Malaysia and Thailand - confirmed infections among citizens who had not traveled to China.

Officials say 425 people have died in China and one in Hong Kong. One death has also been confirmed in the Philippines.

The new coronavirus causes severe acute respiratory infection and symptoms usually start with a fever, followed by a dry cough.

Hong Kong reported its first coronavirus death on Tuesday, the second outside mainland China from a fast-spreading outbreak that has killed 427 people and threatened the global economy.

China’s markets steadied after losing $400 billion in stock values the previous day, and global markets also recovered from a sell-off last week. But bad news kept coming.

The Chinese-ruled gambling hub of Macau asked casino operators to close for two weeks to help curb the virus.
