Eradicating smallpox was one of the great medical success stories in human history. The disease once killed large numbers of people, but vaccination programs brought case numbers to zero by the 1970s. Smallpox explores the history and science behind this disease, as well as how it’s treated. Easy-to-read text, vivid images, and helpful back matter give readers a clear look at this subject. Features include a table of contents, infographics, a glossary, additional resources, and an index. Aligned to Common Core Standards and correlated to state standards.
