Most countries have accepted that covid cannot be eradicated. Helped by vaccines and treatments, they have decided to live with the virus. China, however, is still determined to defeat or at least contain it. The discovery of dozens of cases in Beijing has led to mass-testing (see China section). Individual neighbourhoods are being locked down. This is less harsh than the medicine applied to poorer cities, dozens of which have been entirely sealed off. Still, Beijing could be next. Do you think that Covid-19 will end ?
