Medical Officer of Health (London). Reports.The reports were produced each year by the Medical Officer of Health (MOH) of a district and set out the work done by his public health and sanitary officers. The reports provided vital data on birth and death rates, infant mortality, incidence of infectious and other diseases, and a general statement on the health of the population. As the work of public health departments expanded, so too did the reports: by the 1930s we are given details on such matters as: (1) numbers visiting maternity and child welfare clinics; (2) pints of free milk dispensed; (3) statistics for use of venereal disease clinics; (4) numbers of tubercular children attending open-air schools; & (5) Poor Law infirmaries and municipal hospitals.
