The new coronavirus has been declared a global emergency by the World
Health Organization, as the outbreak continues to spread outside China.
The concern is that it could spread to countries with weaker health systems.
The death toll for the now stands at 170 people in China.
The WHO said there had been 98 cases in 18 countries outside of the country, 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.
Reports say the WHO will now be able to support lower and middle
income countries, helping them strengthen their disease surveillance and
prepare them for possible cases.
Researchers are racing to develop a vaccine to protect people from the virus.
One lab in California has plans for a potential vaccine to enter human trials by June or July.
