Hansenologia Internationalis: Leprosy and Other Infectious Diseases is an official, multidisciplinary, open-access scientific journal of the Lauro de Souza Lima Institute, which is part of the Health Services Coordination of the São Paulo State Health Department.

The journal's primary mission is to publish and disseminate scientific knowledge in leprosy. In particular, it aims to advance scientific research, improve healthcare practices, and strengthen policies to control and eliminate the disease.

Hansenology interacts with various health sciences, including dermatology, infectious diseases, and public health. Its scope of interest, therefore, focuses on studies employing epidemiological approaches and control protocols, as well as the investigation of dermatoneurological clinical manifestations, the disease's pathophysiology, pharmacotherapeutic protocols, and laboratory tests that aid diagnosis and assess treatment failure. These tests employ cellular and molecular tools that encompass genetics, immunology, microbiology, and pathology. The journal also publishes manuscripts on topics such as disability prevention, rehabilitation, history, human rights, education, and health communication in leprosy.

As such, the journal is intended for the scientific community and professionals involved in research, care, teaching, and the formulation of public policies related to leprosy and other infectious diseases. Its content is geared toward researchers, faculty members, students, and professionals in the health sciences and related fields, including physicians, nurses, occupational therapists, psychologists, social workers, nutritionists, biologists, biomedical scientists, pharmacists, epidemiologists, public health professionals, historians, and sociologists.

The journal was printed and distributed free of charge until 2008. In 2009, following trends in the field of scientific dissemination, Hansenologia Internationalis transitioned to being available exclusively online, on a biannual basis. Since 2021, it has adopted a continuous publication model, in which articles are made available immediately after being reviewed, approved, and formatted, eliminating the need to wait for the complete assembly of issues or serialized editions. This model promotes speed in the communication and dissemination of research, offering numerous advantages to all users of scientific information.

The publication of a given issue covers the period from January to December of the current year. Manuscripts that, after all procedures, are approved for formatting by November 30 will be published in the same year. Texts approved later will be published in the following year.

HI publishes original articles in Portuguese, Spanish, and English. If written originally in English or Spanish, the article must include the Portuguese version. The title, abstract, and keywords of the manuscripts are required in Portuguese, English, and Spanish.

The Hansenologia Internationalis accepts manuscripts for publication in the following categories: editorials, original articles, review articles, clinical studies, case reports, experience reports, opinion pieces, brief communications, guides, protocols, guidelines, standards, and technical manuals, interviews, letters to the editor, and obituaries. If necessary, the journal may also publish errata and retractions, as well as review of accepted articles, subject to the consent of the authors and reviewers.

The journal publishes, as a supplement, proceedings containing abstracts of events in the field of Hansenology; however, this type of document is not eligible for indexing in databases.

The journal is registered with Crossref and assigns a unique persistent identifier, a Digital Object Identifier (DOI), to all published articles under the prefix DOI: 10.47878. In addition, it is registered with the International ISSN Center as Hansenologia Internationalis, under the electronic ISSN number 1982-5161.

The abbreviated title is Hansen. Int., which should be used in bibliographies, footnotes, references, and bibliographic captions.

The editorial policies of this journal are presented under the ‘Editorial Policies’ tab and are registered with the Diadorim: the directory of editorial policies for Brazilian scientific journals and with the Sherpa Romeo.
