A mysterious virus has now killed six people in China, state media reported Tuesday, as authorities confirm that almost 300 people in the country have been infected.

Cases have also been recorded in neighbouring countries as authorities try and stop the disease from transmitting after experts confirm that

This map shows where cases have been confirmed, with the orange circle representing the city of Wuhan, where the virus was first recorded at the end of last year. It is home to 11 million people.

Here is where is represented on the map, and how many cases have been recorded there as of Tuesday morning:

• Wuhan, China: Around 270 cases
• Guangdong province, China: 15 cases
• Beijing, China: 5 cases
• Shanghai, China: 2 cases
• Thailand: 2 cases
• Taiwan: 1 case
• South Korea: 1 case
• Japan: 1 case

These people are all Chinese citizens from Wuhan or are people who had recently visited, the various authorities said.

Other countries, including Singapore, have reported suspected cases.

Some experts believe that the number of those infected could be higher: When China claimed 45 people had been infected earlier this month, academics from Imperial College London suggested the true number of infected people was somewhere around 1,700.

Health authorities in Hong Kong, Singapore, and Tokyo are screening passengers flying in from Wuhan at airports, and the US Centers for Disease Control and Prevention (CDC) is doing so at airports in New York, Los Angeles, San Francisco.

The virus, called 2019-nCoV, was first detected in the city of Wuhan, central China, at the end of 2018. As it is a new strain of coronavirus - which is one that infects the nose, throat, or sinuses - that has not been seen by humans before, scientists are scrambling to understand the treat it.

Authorities on Monday said the virus can spread from one human to another, having previously said that they believed it could only spread from animals to humans.

Fears that the virus could spread further are heightened as hundreds of millions of Chinese people prepare to travel to mark the weeks-long Chinese New Year celebration - travelling around the country and the world, often in crowded trains and planes.

The World Health Organization said it will hold a meeting on Wednesday to decide whether to declare "a public health emergency of international concern," and what recommendations to make. It has previously declared such an emergency for swine flu and Ebola.
