The Memórias do Instituto Oswaldo Cruz has decided to simplify the requirements regarding the format of submitted manuscripts. From now on, all manuscripts  may be submitted in any text format as long as the common subdivision of scientific articles are followed, e.g. introduction, materials and methods, results, discussion and  references.  For Reviews and Perspectives articles, authors may use the sections that best suit the structure and content of the proposed manuscript. All manuscripts should  contain, besides the title and abstract, full details of authors and institutions, acknowledgements of any technical or financial assistance as well as state any conflicts of interest. This flexible text format will be used for the initial analysis and peer review.

Figures and tables must be understandable without reference to the text

Figures: presented in tiff format with a minimum of 300 dpi.  Photographs must be sharply focused, well contrasted, and if mounted onto a plate, the figures should be numbered consecutively with Arabic numbers. Magnification must be indicated by a line or bar in the figure, and referenced, if necessary in the caption (e.g., bar = 1 mm). Plates and line figures should either fit one column (8 cm) or the full width (16.5 cm) of the page and should be shorter than the page length to allow inclusion of the legend. Letters and numbers on figures should be of a legible size upon reduction or printing. A colour photograph or a related illustration is used in social media of the Journal (Twitter, Instagram and Facebook) for brief information about the content of accepted articles. Authors are invited to submit illustrations with legends from their manuscript for dissemination in social media.

Tables: should supplement, not duplicate, the text and should be numbered with Roman numerals. A short descriptive title should appear above each table, with any explanations or footnotes (identified with a, b, c, etc.) below.

Supplemental material: refers to files which authors supply for publication alongside their article. They should generally be additional pieces to the article that could not be included in the issue, such as appendices, spreadsheets, tables, figures that is impossible to produce within the article. These files will be sent to reviewers for peer review, along with the article’s main files.

We recommend that Supplementary files be in the following format:
- Excel or any spreadsheet should be uploaded in PDF format or provide link to access files
- Supplementary figures with five or more pieces please provide a PDF file with as many figures as possible.

We recommend providing small size files for quick download.

Review/Perspective: articles in “review/perspective” format are accepted only by means of invitations made by the editor or associated editors.

Alternative format: manuscripts may be submitted following the "Uniform Requirements for Manuscripts Submitted to Biomedical Journals" produced by the International Committee of Medical Journal Editors also known as the Vancouver Style. In this case, authors should follow the guidelines in the fifth edition (Annals of Internal Medicine 1997; 126: 36-47, or at the website http://www.acponline.org/journals/resource/unifreqr/htm) and will be responsible for modifying the manuscript where it differs from the instructions given here, if the manuscript is accepted for publication.
Authors should also follow the Uniform Requirements for any guidelines that are omitted in these Instructions.

Once a paper is accepted for publication, no changes to the original manuscript will be allowed except for minor corrections.
