Last summer, at a hospital in England, a man in his 70s being treated for complications with cancer tested positive for covid-19. He had lymphoma, and the disease plus his drugs weakened his immune system, making him particularly susceptible to the virus. He wasn’t too bad off, considering, and was sent home. That was Day 1. This is the story of what the doctors witnessed, over the course of his illness: the evolution of covid-19 inside his body. Before their eyes, they get a hint of what might be to come in the pandemic.
