How does a doctor feel when he saves patients from an unexplored fatal disease? How has isolation affected people's mental health? Here is a book by Gavin Francis, author of the best-selling book A Surgeon's Journey Through the Human Body, who was already faced with the coronavirus pandemic as a general practitioner. In it, he talks about the most difficult and unpredictable months of his career. And also about the courage of doctors who, risking themselves, worked in the “red zone” to stop the spread of infection. The publishing design is preserved in PDF A4 format.
