In lower income countries, shortages and costs of Covid-19 testing kits undermine the efforts to keep the virus under control. But Rwanda is now implementing a new form of pooled testing which can identify all infected individuals in a population without testing everyone, and it does so at tiny fraction of the cost. It was devised by Prof Wilfred Ndifon and Prof Leon Mutesa in Kigali.

Taiwan has been one of the countries that has most effectively kept its population safe from the spread of Covid-19. Cindy Sui visits one of Taipei鈥檚 main hospitals to see the super-rigorous regime in place to protect its nurses from infection and prevent the spread of the virus from the hospital to the community.
