I think the foresight of the author while writing this book is also amazing. Because this book was published in 1912, and even if it is not as effective as this epidemic, a large-scale epidemic only happened 8 years after this book was published. In fact, on the one hand, it is a highly predictive book because it is an epidemic similar to the current Coronovirus. Maybe the coronovirus is not as deadly as this epidemic, but there are both psychological and physical damage to people during and after the epidemic.
