The new coronavirus has been declared a global emergency by the World Health Organization, as the outbreak continues to spread outside China.

"The main reason for this declaration is not what is happening in China but what is happening in other countries," said WHO chief Tedros Adhanom Ghebreyesus.

The concern is that it could spread to countries with weaker health systems.

At least 213 people have died from the virus in China.

The WHO said there had been 98 cases in 18 other countries, but no deaths. Most cases have emerged in people who have travelled from the Chinese city of Wuhan, where the outbreak began.

However, there have been eight cases of human-to-human infection - in Germany, Japan, Vietnam and the United States.

Speaking at a news conference in Geneva, Dr Tedros described the virus as an "unprecedented outbreak" that has been met with an "unprecedented response".

The number of novel coronavirus cases is changing quickly. A real-time tracking map shows us just how quickly.

The dashboard collects data from the US Centers for Disease Control and Prevention, the World Health Organization, the European Centre for Disease Prevention and Control, the Chinese Center for Disease Control and Prevention and the Chinese website DXY, which aggregates data from China's National Health Commission and the CCDC. The results populate a worldwide view of coronavirus cases in real time.

See the map here The coronavirus case map updates in real time as global health agencies confirm more cases.

The clickable map pinpoints regions where patients have been diagnosed with coronavirus -- the more cases in a region, the larger its dot on the map (right now, the largest dot belongs to the Hubei Province, where the outbreak originated).

The map tracks deaths, too, in total and by city.

Lauren Gardner, director of the Center for Systems Science and Engineering and a civil engineering professor at Johns Hopkins, said the map isn't just a resource for the public -- health officials can download the data, which will inform research on the coronavirus in the future.

"We built this dashboard because we think it is important for the public to have an understanding of the outbreak situation as it unfolds with transparent data sources," she said. "For the research community, this data will become more valuable as we continue to collect it over time."

The dashboard also puts the outbreak into perspective: There are already more than 6,000 confirmed cases in mainland China and fewer than 100 everywhere else in the world.

The CDC regularly updates its map of confirmed coronavirus cases, too, though it shows cases by country rather than by region or city.
