Articles Types

Authors must submit manuscripts that are not published, in press, or submitted to other scientific journals, books or other venues that could be considered formal publication (including preprints or future submissions). The correspondence for each article must be carried on only by the corresponding authors, who should provide an institutional and verified email address. Articles without this requirement will not be considered for evaluation or publication.



Original Articles should present novel work that makes a significant impact within the aims and scope of the journal, and which provides an important advancement in the reader’s knowledge or understanding. Supporting data or additional experimental details can be submitted as Supplementary Appendix.

Format guide:

  • Word limit: 3500 words (excluding the abstract and references)
  • References: unlimited
  • Tables/Figures: Do not repeat the data extensively in tables or figures.



Brief Commentaries are short manuscripts that have important and generally preliminary data on a specific issue.

Format guide:

  • Word limit: 1700 words (excluding the abstract and references)
  • References: 10-20
  • Abstract: up to 75 words, unstructured
  • Tables/Figures: a maximum of 1 figure or table



Infectious Diseases and Tropical Medicine publishes narrative reviews on current topics and recent advances in the scientific literature.

Reviews highlight recent advances in research, current challenges and unmet needs. Authors are also encouraged to provide their perspectives on current progress and future directions.

  • References: unlimited
  • Abstract: 300 words or less, unstructured
  • Tables/Figures: minimum 2 and no more than 8 figures or tables



Format guide:

  • Word limit: 4000 words (excluding the abstract and references)

  • Abstract: 300 words or less and it should be structured (OBJECTIVE; MATERIALS AND METHODS; RESULTS; CONCLUSIONS)
  • Tables/Figures: minimum 2 and no more than 8 figures or tables

Please, note that a systematic review analyzes a defined research question by collecting and summarizing all empirical evidence that fits pre-specified eligibility criteria. On the other hand, a meta-analysis reports the use of statistical methods to summarize the results of these studies.

According to the International Committee of Medical Journal Editors (ICMJE), to conduct a systematic review or meta-analysis, the Authors have to follow the guidelines of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA).

To perform a high-quality analysis, the Authors are requested to follow some specific guidelines:

  • Authors have to clearly state objectives and pre-defined eligibility criteria for studies (e.g., inclusion and exclusion criteria, etc.);
  • Authors have to clearly describe the methods used for locating, selecting, extracting, and synthesizing data;
  • the methodology should be accurate and reproducible;
  • Authors have to conduct a systematic search that aims at identifying all relevant studies on the topic analyzed;
  • Authors have to assess the validity of the findings of the included studies (e.g., risk of bias);
  • Authors have to present a systematic analysis with detailed characteristics and findings of the included studies.



Case Reports present a notable medical case or series of related cases of particular interest to the field of infectious diseases and tropical medicine. Case Reports must be accompanied by a review of the literature on the specific topic covered in the manuscript.

Format guide:

  • Word limit: 1500 words (excluding the abstract and references)
  • Reference limit: 20
  • Abstract limit: 200 words, and it should be structured (BACKGROUND or INTRODUCTION or OBJECTIVE; CASE REPORT or CASE PRESENTATION; CONCLUSIONS)
  • Tables/Figures limit: 4

Case Reports have to include a final section for the informed consent. Permission or written consent should be obtained to draft the manuscript. The consent can be obtained by the patient’s parents in case the patient is a minor.



Editorials are short articles that provide insight into issues of topical importance to the journal’s target audience or researchers. The articles should provide an expert perspective on a topic of recent interest. This contribution is usually solicited by the Editors. If unsolicited, the Authors are advised to contact our Editorial Team ( with an outline of the proposed review and CV of the Authors.

Format guide:

  • Word limit: 1400 words
  • References: 15 or less
  • Tables/Figures: A maximum of 1 figure or table



Letters to the Editor consist of comments on an article published in Infectious Diseases and Tropical Medicine. The inclusion of Letters to the Editor in the journal is at the discretion of the Editor-in-Chief, and they may undergo external peer review. All Letters to the Editor will be subsequently sent to the author of the original article, who will have 60 days to provide a Reply to be published alongside the Letter.

Letters are restricted to the discussion of papers already published in the journal, with a maximum of 1,000 words, one table or figure and up to 20 references.



Case/Photo Quiz are based on a question-and-answer format.

It usually illustrates an unusual disease or an atypical presentation of an infectious disease, to challenge the reader on its differential diagnosis.

The history of the case needs to be reported in the question portion of the article, but it should not disclose the diagnosis.

Format guide:

  • The question should be written in a single paragraph
  • Figures: 3 or less
  • The answer should give the diagnosis and outline or include the key teaching points



All clinical trials submitted to Infectious Diseases and Tropical Medicine must be registered to the WHO International Clinical Trials Registry Platform (ICTRP) or ClinicalTrials.govThe International Committee of Medical Journal Editors (ICMJE) defines a clinical trial as “any research project that prospectively assigns human subjects to intervention or comparison groups to study the cause-and-effect relationship between a medical intervention and a health outcome. Studies designed for other purposes, such as to study pharmacokinetics or major toxicity (e.g., phase 1 trials), are exempt.”

For definitions and further information, please check ICMJE Recommendations (“The Uniform Requirements”)found in ICMJE’s Uniform Requirements for Manuscripts Submitted to Biomedical Journals. Please note, however, that, unlike ICMJE, Infectious Diseases and Tropical Medicine does not require trials to be registered before enrollment begins, although our journal does strongly encourage this practice. When submitting your manuscript, please include the unique trial number and the name of the registry (e.g., or ISRCTN) at the end of the abstract and in your cover letter.



Other guidelines have been developed and should be followed for different study designs:

  • CONSORT for randomized trials;
  • STROBE for observational studies;
  • STARD for studies of diagnostic accuracy.

In particular, good sources for reporting guidelines are the EQUATOR Network and the NLM’s Research Reporting Guidelines and Initiatives.
