The plague struck swiftly, perhaps not by human standards, but certainly quickly enough to sicken three-quarters of the people of the Earth within fifteen years. At first the disease seemed very widespread and indiscriminate, but five years into the plague, the CDC’s Chief Epidemiologist, Dr. Sandra Fry, determined that it was most virulent in high population centers with a heavy industrial base.
The nation with the largest number of deaths by year five was China, which correlated very highly to their level of pollution and generally poor environmental standards.
However, as the plague progressed, the Euro-Asian continent fell, as did North and South America. By year ten, four billion people were dead. Disposal of the bodies in any civilized manner was impossible due to the shortage of manpower and resources, so they were bulldozed into mass graves.
