There were two major public health acts. The first in 1848 resulted from pressure by Chadwick and other public health reformers to do something to stop the spread of disease, particularly cholera. It created the General Board of Health which could set up Local Boards of Health if a) ratepayers petitioned for it, b) the death rate was particularly high. The second act in 1875 was passed by Disraeli and consolidated the 1866 Sanitary Act and other sanitary legislation.
