Smallpox lesions have been found on mummies. Skeletons thousands of years old show bone deformities that may have come from syphilis. In Outbreak!: 50 Tales of Epidemics that Terrorized the World, Beth Skwarecki chronicles the devastation caused by viruses, bacteria, fungi, parasites, prions, dietary insufficiencies, and other scourges, from those known in ancient times, including malaria and plague, to more recent outbreaks, such as those of severe acute respiratory syndrome (SARS) and Ebola. Skwarecki provides 3-5 page summaries for each epidemic, telling what happened and including the current threat level, treatment, and research findings.
