Bangladesh, with its 168 million inhabitants, is one of the poorest and most densely populated countries in the world. Millions live cheek by jowl in slums, where 10 or more households share a toilet. People move around the country on packed buses, and still throng to markets and mosques. Last week, for instance, tens of thousands gathered in a field to pray for an end to covid-19.
