Coronavirus underestimated: Virologist

With the United States confirming its first case of the newly identified coronavirus, there's concern about the spread of the disease to New Zealand. More than 300 people have been infected, and six have died, in the Chinese city of Wuhan where the virus originated. Other cases have been reported in South Korea, Thailand and Japan. The World Health Organisation is meeting later today to consider whether to declare a public health emergency. Lynn Freeman talks to virologists Dr Lance Jennings from the University of Otago and Matt Frieman from the University of Maryland School of Medicine whose lab is working on the virus.
