A public health journal is a scientific journal devoted to the field of public health, including epidemiology, biostatistics, and health care (including medicine, nursing and related fields). Public health journals, like most scientific journals, are peer-reviewed. Public health journals are commonly published by health organizations and societies, such as the Bulletin of the World Health Organization or the Journal of Epidemiology and Community Health (published by the British Medical Association). Many others are published by a handful of large publishing corporations that includes Elsevier, Wolters Kluwer, Wiley-Blackwell, Springer Science+Business Media, and Informa, each of which has many imprints (which are brands named after former independent publishers that were merged or acquired). Many societies partner with such corporations to handle the work of producing their journals.
