Governments around the world are planning to roll out contact tracing apps to help contain the spread of coronavirus. But will they work? Ed Butler speaks to BBC technology reporter Chris Fox about the technology that underpins them, and to researcher Natalie Pang from the National University of Singapore about the experience of Singapore's TraceTogether app, launched last month. But conventional human contact tracing has been around for decades. UK contact tracer Karen Buckley describes the challenges of the job, and John Welch from the non-profit Partners in Health describes his experience of contact tracing amid the Ebola outbreak in Africa and argues that apps are no substitute for an army of dedicated human contact tracers.(Photo: A man holds a smartphone showing a contact tracing app launched in Norway this month.

In today's Business Daily we're asking some awkward, often neglected questions - will the economic recession itself prove more fatal than coronavirus? How do and how should governments put a value on human life? To help answer these questions we speak to Bryce Wilkinson, a senior fellow at the New Zealand Initiative; US science journalist and biostatistician, Lynne Peeples and John Broome, a Professor of Moral Philosophy at Oxford University.

The World Bank has warned global remittances, which is the money migrant workers send home, will fall by around 20% in 2020 because of coronavirus. The bank predicts this will affect the income of at least tens of millions of families. One such family is that of Smitha in Kerala, whose husband is stuck in Dubai unable to work due to lockdown. But it’s not just about subsistence. Michael Clemens at the Centre for Global Development says remittance flows are a crucial resource for helping families and communities pull themselves out of poverty, and the effects of this sharp fall in remittances will be felt for many years to come. Meanwhile, Yvonne Mhango, Sub-Saharan Africa at Renaissance Capital, explains how the impact felt in Africa will differ across regions. And Michael Kent, CEO of digital payments service Azimo, explains how services like his could fill the gap left by the shuttering of brick and mortar transfer shops. Producer: Frey Lindsay.
