Does quarantining do more harm than good?

How will China's efforts to contain the corona virus affect the country's economy? Ed Butler asks our economics correspondent Andrew Walker, as well as a sceptical Lawrence Gostin, professor of health law at Georgetown University, who says the belated attempts to stop the spread of the epidemic are simply shutting the stable door after the horse has bolted. Moreover, how does quarantining affect those caught up in the net? Ed speaks to Ben Voyer, professor of psychological and behavioural science at the London School of Economics. He also hears the personal story of a survivor of the West African Ebola outbreak. Plus the BBC's China social media editor Kerry Allen explains how the Chinese authorities are doing their best to be transparent about the spread of the disease, while avoiding panic.
