At the end of May, the WHO said that South America has become the new epicentre of the covid-19 pandemic.

The majority of those with covid are in Brazil - not entirely surprising given it is the most populous - but in neighbouring Peru, numbers are growing too.

And it’s to Peru that we turn to talk to our guest today, Valerie Paz-Soldan is a social scientist and director of the Tulane Health Office for Latin America - part of the university’s school of public health and tropical medicine.

She joins us to talk about the pattern of the virus in Peru in particular, but elsewhere in the region, and how the pandemic is overwhelming an already stressed healthcare system.
