A statement indicating that permission has been obtained must be included in the relevant legend/footnote.

Preprint Policy

Please note that Infectious Diseases and Tropical Medicine does not accept submissions of manuscripts that have previously been made available online as a preprint on a preprint server or on the Authors’ own website.

Presentation of Manuscripts

The following parts should appear in all manuscript types and are mandatory for publication:

  • TITLE PAGE: the title page must contain the Authors’ names, appointments, and affiliations, along with the full contact details of the Corresponding Authors, including their current e-mail addresses. A full and a short-running title should be given, plus a small number of keywords (5-10) for indexing purposes. We recommend that the keywords are specific to the article.
  • COVER LETTER: the cover letter briefly outlines the article’s relevance to the journal’s audience and how the article advances understanding of the field. It must include contact information [affiliation, postal address, e-mail address, telephone number] for all Authors. Authors should also indicate a Corresponding Author to whom correspondence will be sent if the manuscript is accepted for publication. In the Letter, the Authors must confirm that the manuscript has been submitted solely to this journal and is not published, in press, or submitted elsewhere (including preprint servers). They have to confirm that all the research meets the ethical guidelines, including adherence to the legal requirements of the study country. The cover letter must be signed by the Corresponding Author on behalf of all the other Authors.
  • LIST OF ABBREVIATIONS: Abbreviations should be defined the first time they appear in the abstract, the main text, and the first figure or table. 
  • ABSTRACT: The abstract should count a maximum of about 300 words. It should be organized into sections using the following headings: BACKGROUND (for case reports) or OBJECTIVE; PATIENTS AND METHODS or MATERIALS AND METHODS or SUBJECTS AND METHODS or CASE REPORT/PRESENTATION; RESULTS; CONCLUSIONS. *The Abstract is not mandatory for Letters to the Editor and Editorials. Please see full details under “Article Types”.

The paper should then proceed conventionally: Introduction, Patients and Methods or Materials and Methods or Subjects and Methods or Case Report/Presentation, Results, Discussion, Conclusions, and References. Pages should be numbered consecutively in Arabic numerals, including tables, figure legends (with magnifications if needed), and declarations.

  • REFERENCES: References should be numbered in the order in which they are first mentioned in the text and should be located in superscript and not in parenthesis. References must follow numerical order and be identified in the text, tables, and legends by Arabic numbers in superscript. The authors must verify the References against the original documents.

Authors should observe the following guidelines.

  1. Do not attempt to make your output approximate or match the typeset page.
  2. Be consistent in style (i.e., units, abbreviations).
  3. End paragraphs in a uniform manner and in a different manner from line endings within paragraphs. A frequently used paragraph ending is simply two carriage returns.
  4. Use double spacing in your document. Do not add extra line spacing (except as a normal paragraph ending indication) above or below titles, subheads, or between paragraphs.
  5. Avoid using multiple spaces (horizontal) in your electronic manuscript. End sentences with only one space. Never use multiple spaces for the horizontal positioning of text.
  6. Table and figure captions should be prepared in separate files. The Authors have to indicate this material within the text.
  7. Additional tables or figures and/or extra methodological detail can be included in a separate Supplementary Appendix.

References, Tables, and Figures


When reporting the reference numbers in the text, you have to follow these rules: “1-2” must be written as “1,2” and so on. You have to put “-“ just in case you have many consecutive numbers. For example: “1,2,3,4,5,6” must be written as “1-6”;

References numbers must follow a chronological order within the text and must be inserted before the punctuation. (YES 12.  – NO.12)

Complete all the references in accordance with the Instructions for the Authors: you must list all the Authors (NOT et al), year without month of publication, and name of the journal. You have to write the international acronyms without any punctuation; you must put a space after the semicolon and colon (NOT 2014;2014:907915, YES 2014; 2014: 907915); moreover, initial and final pages must be entirely reported (NOT 135-46; YES 135-146).

In the references, you must substitute “and” with “,” (comma) before the last author’s name;

INCORRECT: Carvalho J. F. Lack of response of Chikungunya chronic infection with low-dose naltrexone: a case series. Infectious Diseases and Tropical Medicine 2024;10:e1390.

CORRECT: Carvalho JF. Lack of response of Chikungunya chronic infection with low-dose naltrexone: a case series. Infect Dis Trop Med 2024; 10: e1390.



Figure legends should be included in the main text of the manuscript and not form part of the figures. The Authors are encouraged to send the highest-quality figures possible. For the accepted file format, see below:


Document Files Graphic Files Graphic Files
• Word






• TIF (or TIFF)
• JPG (or JPEG)
• BMP 
• QuickTime
• AVI 

The figure resolution/specification for various types of original figures, at their final size, should be as follows: Line art – Minimum 600 dpi, measuring preferably 13×18 cm and no more than 20×25 cm in size. Halftone (i.e., both B/W and Color photographs) – Minimum 300 dpi, measuring preferably 13×18 cm and no more than 20×25 cm in size. Line and tone (line art and halftone combined) – Minimum 600 dpi, measuring preferably 13×18 cm and no more than 20×25 cm in size.

For line figures, the lines should be solid, the text in a standard font and not blurred, and the overall image should be sharp and clear. Avoid using tints if possible; if they are essential to the understanding of the figure, try to make them coarse. As a guide, if the electronic files are viewed at 400% on the computer screen and they look blurred or pixelated in any way then they will NOT be of sufficient quality for printing.

Tables should be self-contained and complete; they must not duplicate the information already contained in the text. They should be supplied as editable files (word files), not pasted as images. All abbreviations must be defined in footnotes. Footnote symbols: †, ‡, §, ¶, should be used (in that order) and *, **, *** should be reserved for p-values. Statistical measures such as SD or SEM should be identified in the headings.

Figure and table legends must be able to stand alone in the text, and thus, full descriptive legends for all figures and tables should be supplied.


All measurements should be in SI units, with the exception of hemoglobin (g/dL) and blood pressure (mmHg). Original observations recorded in other units should be stated, together with the appropriate conversion factors. Standard abbreviations without punctuation are used. Units, Symbols, and Abbreviations (1988) published by the Royal Society of Medicine, and SI: The International System of Units (1982) from HMSO both provide useful guides. Abbreviations, used sparingly, should follow the first full spelling, in parentheses.


Sequence variants should be described in the text and tables using both DNA and protein designations whenever appropriate. Sequence variant nomenclature must follow the current HGVS guidelines, where examples of acceptable nomenclature are provided.


Generic names should, in general, be used. If an Author desires, brand names may be inserted in parentheses. Drug names are spelled out according to the European Pharmacopoeia, but the American spelling should be used after the first use of a drug name.


Methods should be referenced. Two-tailed significance tests should be used unless explicitly stated. Controls should be described as completely as experimental subjects. Measures of location should be accompanied by measures of variability (e.g., mean and confidence intervals) as well as conventional probability values. Clinical trial reports should include the power of the study design.


Research and Publication Ethics

Infect Dis Trop Med follows the guidelines on Good Publication Practice: COPE and ICMJE. These guidelines aim to ensure that articles are published in a responsible and ethical manner, trying to add high-quality scientific works to the field of scholarly publication.

Moreover, as Infect Dis Trop Med follows the ICMJE’s Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals, we expect that Authors, reviewers and editors follow the best-practice guidelines on ethical behavior.

Authors, the journal and reviewers must abide to the following:

  • Authors and the Journal have to follow the Good Publication Practice: COPE and ICMJE guidelines during submission. Please, also check the Scientific Misconduct, Expressions of Concern, and Retraction guidelines from ICMJE.
  • Infect Dis Trop Med, Authors and reviewers have to guarantee confidentiality and do not have to share information about manuscripts, including peer-review, their content or status in the review process, concerns raised by reviewers, and the final decision about rejection or acceptance, to anyone other than the Authors and reviewers.
  • Infect Dis Trop Med and reviewers have to ensure the processing of manuscripts timely. On the other hand, Authors have to ensure timely communication and availability to reply to concerns during the review and publication process.
  • The peer review is the most critical assessment of the scientific process and should be followed in a rigorous manner. Specific information about our peer-review process is available here.
  • Integrity should be the standpoint for both Authors and the journal. The Editorial decisions about the acceptance or rejection of a manuscript should be based on the research’s originality, contribution to the scientific society, relevance to the topic of the journal and quality standards. Those decisions should not be jeopardized by commercial interests or personal relations.
  • The spread of academic culture and scientific knowledge should also support diversity and inclusion for Authors as well as reviewers, editorial board members and editorial staff.


Clinical studies must include a reference to the appropriate Ethics Committee/Institutional Review Board (IRB) approval and have an appropriate Consent Form approved by the Ethics Committee/IRB before enrollment of the research subjects in the study. Appropriate review process and approval should also be documented for all pre-clinical experimental studies submitted. When reporting experiments on human subjects, Authors should indicate whether the procedures followed were in accordance with the Ethical Standards of the Responsible Committee on Human Experimentation (institutional and national) and with the Helsinki Declaration of 1975, as revised in 2000. If doubt exists whether the research was conducted in accordance with the Helsinki Declaration, the Authors must explain the rationale for their approach and demonstrate that the institutional review body explicitly approved the doubtful aspects of the study. Should any questionable approval process emerge, the Editors reserve the right to reject any submitted paper.


When reporting experiments on animals, Authors should indicate whether institutional and national standards for the care and use of laboratory animals were followed. Should any questionable approval process emerge, the Editors reserve the right to reject any submitted paper.


Appropriate consents, permissions and releases must be obtained in case Authors wish to include case details or other personal information or images of patients in their publication. This is to comply with all applicable laws and regulations concerning the privacy and/or security of personal information, including, but not limited to the General Data Protection Regulation (GDPR) (EU) 2016/679.

Patients have the right to privacy that should not be violated without informed consent. Identifying information, including names, initials, or hospital numbers, should not be published in written descriptions, photographs, or pedigrees unless the information is essential for scientific purposes and the patient (or parent or guardian) gives written informed consent for publication. Informed consent for this purpose requires that an identifiable patient be shown the manuscript to be published. Authors should disclose to these patients whether any potentially identifiable material might be available via the Internet as well as in print after publication.


  • Images of patients or research subjects should not be used unless the information is essential for scientific purposes and explicit permission has been given as part of the consent.
  • If identifying characteristics are altered to protect anonymity, Authors should provide assurances that such alterations do not distort scientific meaning.
  • Formal consents are not required for the use of entirely anonymized images from which the individual cannot be identified – for example, x-rays, ultrasound images, laparoscopic images etc.
  • If consent has not been obtained, it is generally not sufficient to anonymize a photograph simply by using eye bars or blurring the face of the individual concerned.


Corrections, Erratum, and Retractions


After acceptance, Authors cannot apply major corrections to the manuscript, Figures, Tables, or authorship. Before publication, we send galley proofs twice to the corresponding author. The Authors are asked to carefully check them (especially for what concerns the name of the Authors, affiliations, and corresponding Authors) and send their approval for publication. After publication, no further corrections can be applied. We publish corrections only when necessary, and one editor deals with them all to ensure that corrections are handled consistently. Generally, we evaluate corrections case by case.

In case Authors discover a discrepancy between the online version and the galley proof, we will normally correct it by making the article correct in the online version.


We publish errata when a significant error has been detected in a published article, and some changes are required. Significant mistakes involve tables, incorrect information, and spelling errors in case they modify the meaning of the article. Corresponding Authors should send an email stating the type of error and the requested corrections. All Authors have to agree with an erratum. To ensure that corrections are handled consistently, one editor deals with them all.

To issue errata, we follow the Council of Science Editors guidelines.

An erratum notice linked to the article to be corrected will be published in the first available issue;

The erratum notice will clearly state the title and Authors, the issue of publication, the DOI, and the PMID in the erratum heading;

Corrections will be clearly stated in the erratum notice from the original version and the date(s) on which the changes were made;

The erratum notice will be freely available to all readers online. A new version with details of the changes in the article will be posted.


Retractions will be considered by Infectious Diseases and Tropical Medicine in case of evidence of unreliable data, plagiarism, unethical research, and misconduct. We consider an expression of concern notice if an article is under investigation.

In particular, the Editor in Chief should consider retracting a publication following guidelines on Good Publication Practice as reported in COPE.

All requests of withdrawal must be sent by the corresponding author, who should provide detailed reasons for retraction. Authors should also provide a signed document stating that all Authors agree with retraction and related reasons.

In case a third party informs us about a mistake, problem, or manipulation related to data or research itself, our Editor in Chief can decide to conduct an independent peer-review to establish whether our published data are reliable or accurate. The Editor in Chief can decide to withdraw an article without the consent of the Authors in case of malpractice or evident mistakes.

Retractions are issued following Good Publication Practice guidelines as reported in COPE:

A retraction notice linked to the retracted article will be published in the first available issue;

The retraction notice will clearly state the title and Authors, the issue of publication, the DOI, and the PMID in the retraction heading;

The retraction notice will be freely available to all readers and will state who is retracting the article and the detailed reason(s) for retraction.


Authors who want to publish in our Journal must follow the guidelines on Good Publication Practice as reported in COPE and Council of Science Editors. These guidelines aim to ensure that articles are published in a responsible and ethical manner.

On a practical level, the first step is an early investigation using our anti‐plagiarism software. Our Journal makes a plagiarism checker by a certificate program on all the articles. Also, articles that are related to the suspected case of plagiarism or other unethical practices are checked accurately by either the reviewer’s feedback and observations or the Editors’ own observations. Our anti‐plagiarism software, however, will not identify “salami slicing”. So, it is imperative that each case is looked at individually and therefore, we do not advocate the use of one statement of actions to penalize the offender. Each case is considered separately and, as editors, we will need to decide if it is a deliberate action on the part of the author or if it is due to a lack of understanding of the requirements of ethical writing. This can happen for new Authors or some Authors where translation to English is often difficult. An example of this is where there are no words/phrases in that language that translate into English, and a developing practice that we noted is the ‘borrowing’ of words, phrases or often sentences that are considered appropriate for what Authors mean to say.

Infectious Diseases and Tropical Medicine disapproves any kind of malpractice and unethical practice.
