The “whole world needs to be on alert” to fight the coronavirus, the head of the World Health Organization’s Health Emergencies Programme has said.
Dr Mike Ryan praised China’s response to the deadly outbreak, saying: “The challenge is great but the response has been massive.”
The WHO will meet on Thursday to discuss whether the virus constitutes a global health emergency.
The Chinese city of Wuhan is the epicentre of the outbreak.
But the virus has spread across China and to at least 16 countries globally, including Thailand, France, the US and Australia.
More than 130 people have died in China and close to 6,000 have been infected.
There is no specific cure or vaccine. A number of people have recovered after treatment, however.
The WHO’s Dr Ryan said an international team of experts was being assembled to go to China and work with experts there to learn more about how the disease is transmitted.
“We are at an important juncture in this event. We believe these chains of transmission can still be interrupted,” he said.
