No information from official or non-official sources is available on the prevalence of enteric fevers in Palestine in pre-war days. Since the establishment of the British Administration (1919) the Annual Reports of the Government Department of Health invariably emphasise the high incidence of enteric fevers. Several papers dealing with the epidemiology of the disease appeared in the Hebrew periodicals Briuth Haam and Harefuah and in 1926 an elaborate Report was submitted to the Department of Health by a Committee of Enquiry appointed by the Department to consider and advise on the situation as regards enteric fever in the country. The data thus accumulated, although very valuable for the local health authorities, did not reveal any peculiar features of more than local interest. Their publication abroad seemed, therefore, superfluous.
