Coronavirus: do facemasks help or hinder?

As the lockdown tightens and a quarter of the world's population are forced to stay at home, Chris Smith and RNZ's Kim Hill link up to talk about the latest coronavirus facts. They explore whether facemasks protect you or just lead to a false sense of security, herd immunity and our lockdown exit strategy, why some people suffer more severe infections than others, and if antibodies from recovered Covid-19 victims can help those dying from the disease... Also, the brilliant Coronavirus Rhapsody sung by Adrian Grimes with lyrics by Dana Jay Bein and music by Queen. Like this podcast? Please help us by supporting the Naked Scientists
