Abstract: | Poor living conditions and inadequate diet were undoubtedly major contributors to high infectious disease death rates in Britain during the nineteenth century, but improvements were not necessarily the precondition for mortality decline. Evidence of consistent improvements is far from conclusive, while different trends for different diseases have to be explained. Scarlet fever and whooping cough death rates did not decline until the last few decades of a century in which measles mortality was continuing high Respiratory and gastro-intestinal complications are frequently involved in conditions of overcrowding and poverty. Death rates for recorded respiratory diseases themselves reveal a downturn at the end of the century, but respiratory tuberculosis mortality declined throughout and smallpox was virtually eliminated through vaccination measures. The interrelated nature and aetiology of these diseases has implications for changes in mortality, while population variables and other transmission factors including social behaviour patterns are probably crucial for an understanding of historical and contemporary trends. |
