This vintage book contains a treatise on smallpox, an infectious disease that was declared eradicated by the World Health Organization in 1980. The disease was caused by one of two virus variants, variola major and variola minor. Those who survived often had severe scarring on their skin and some were left blind. This volume describes in detail the early symptoms of small pox and provides information on its epidemiology and how to treat infected patients. Contents include: "The Disease", "Incubation", "Infection", "Early Symptoms", "Nursing and Treatment", "How Smallpox Spreads", "Vaccination", "The History of Smallpox", "The Present Epidemic", "Some Valuable Opinions in Favour of Vaccination", etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.
