ICD Chickenpox/varicella

"The last issue of the Registrar-General thus, [p. xiii.,] refers to this: "The deaths ascribed to Small-pox in 1886 numbered 275, and were far lower in proportion to the population than in any previous year. There were, however, also 93 deaths ascribed to Chicken-pox; and as this ailment is rarely, if ever, fatal, in all probability most or all of these deaths were really due to Small-pox."--ALEXANDER WHEELER

"In the thirty years ending in 1934, 3,112 people are stated to have died of "chicken-pox," and only 579 of smallpox in England and Wales. Yet all the authorities are agreed that chicken-pox is a nonfatal disease"—M. Beddow Bayly, Case Against Vaccination, London, June 1936, p. 5.
