Epidemiological studies should provide information about the study plan (protocol) covering the study population (age, gender and other important characteristics, e.g. living environment, vaccination history), randomization method or allocation to specific groups. If a form developed by another institution, e.g. WHO, was used for the study, the Author is obliged to obtain the consent of the above-mentioned institution to use the form, if required.

4. Review process:

• Przegląd Epidemiologiczny - Epidemiological Review uses the "double blind review" principle in the review procedure. This means full anonymity of the review, the Authors and Reviewers do not know each other's identities. Therefore, we ask the Authors to pay special attention to ensuring that the manuscript is prepared in such a way as not to reveal the identity of the Authors. The Authors' names and affiliations should be placed only in specially designated places in the ES and should not be repeated in the content of the article.
• All submitted articles undergo a preliminary assessment by the Editorial Office in terms of compliance with the topics and fields in which the journal specializes.
• Articles that meet the substantive and editorial criteria are then sent to two independent Reviewers who assess the scientific value of the paper.
• Reviews are prepared in an electronic review form available after accepting the invitation to review directly from the link in the e-mail or after logging in to your account in the ES.
• The duration of the review process is closely related to the availability of Reviewers and may be longer during holiday or holiday seasons or when the publication concerns a field with a limited number of specialists.
• Reviews (including Reviewer comments directly in the manuscript, if added) are sent to Authors. In the event of the Editorial Office's decision on the possibility of publishing the work after making corrections or a major revision, the Editorial Office requires the Authors to refer to all comments submitted by the Reviewers and to precisely mark all corrections, changes and additions in the text, and if it is not possible to introduce a correction, to respond to the comment in a letter to the Reviewers.
• The revised article undergoes another editorial review, and then the Editorial Office makes the final decision regarding publication of the manuscript.
• The final publication date depends on the number of manuscripts waiting for publication.
