A letter from Brazil: We all live in a yellow submarine

This country’s Bureau Of Tropical Diseases has issued an urgent warning about an expected massive outbreak of yellow fever next Friday.

Ground Zero will be the Estadio Castelao in Fortaleza where Brazil will meet Colombia in the second of the World Cup quarter-finals.

And nobody who has already succumbed to the happy delirium of this compelling tournament will be in any rush to find a cure.
