Have governments gone too far in imposing lockdowns to curb the spread of Covid-19? Why did governments use this strategy? Is the original Covid-19 still circulating - or did it die out in June? We speak to Brian Pottinger, South African author and former Sunday Times journalist who has undertaken an in-depth investigation into these issues, for his new book: 'States of Panic: Covid-19 and the new medieval'. And, we hear from our partners a Bloomberg about the new response - and mistakes - to Covid-19 by US President Joe Biden, starting with his appointment of Rochelle Walensky to head the country’s Centers for Disease Control and Prevention.
