How far did the role of the British government in public health change in the years 1875-1948?

The Public Health Act 1875 (c 55) is an Act of the Parliament of the United Kingdom, one of the Public Health Acts,[2] and a significant step in the advance of public health in Britain.

Its purpose was to codify previous measures aimed at combating filthy urban living conditions,[3] which caused various health threats, including the spread of many diseases such as cholera and typhus.
