Peer Review Timeline
We are committed to transparent, efficient peer review while maintaining rigorous quality standards. Our multidisciplinary editorial board ensures expert evaluation across all research areas covered by JHAI.
Submission & Initial Screening
Your manuscript undergoes automated plagiarism screening (iThenticate) and editorial assessment for scope, quality, and completeness. Manuscripts outside our scope or with major formatting issues are returned at this stage.
3 daysEditor Assignment
An associate editor with expertise in your specific research area (microbiome, gastroenterology, immunology, nutrition, veterinary medicine, etc.) is assigned to handle your manuscript and select appropriate peer reviewers.
2-3 daysPeer Review Process
Typically 2-3 expert reviewers from relevant disciplines evaluate your manuscript for scientific rigor, methodological soundness, novelty, and significance. Reviewers assess experimental design, statistical analysis, interpretation of results, and contribution to the field.
21 days averageEditorial Decision
The handling editor synthesizes reviewer comments and makes a decision: Accept, Minor Revisions, Major Revisions, or Reject. You receive detailed feedback regardless of outcome, with specific guidance for revisions if applicable.
3-5 days after reviewsRevision Submission
If revisions are requested, you submit your revised manuscript with a detailed response to reviewers. Major revisions may undergo additional peer review; minor revisions are typically evaluated by the editor only.
Author timeline variesRe-review & Final Decision
Revised manuscripts are evaluated to ensure all reviewer concerns have been adequately addressed. The editor makes a final accept/reject decision based on the quality of revisions.
14 days for major revisionsProduction & Publication
Accepted manuscripts undergo copyediting, typesetting, and author proof review. Your article is published online immediately upon completion, with full open access and DOI assignment.
10 days post-acceptanceTotal Timeline: From submission to publication, most manuscripts complete the process in approximately 60 days.

Frequently Asked Questions
What is your acceptance rate and how does it compare to other journals?
Our acceptance rate is 62%, reflecting our commitment to publishing high-quality research while remaining accessible to researchers across career stages and institutions. We reject manuscripts primarily due to scope mismatch, methodological flaws, or insufficient novelty - not arbitrary quotas. This balanced approach ensures quality while supporting the research community.
How long does the review process take?
Average time to first decision is 21 days for most manuscript types. Short communications and case reports typically receive decisions within 14 days. Systematic reviews and complex multidisciplinary studies may take up to 28 days. We provide regular status updates and never leave manuscripts in limbo without communication.
Do you charge article processing charges (APCs)?
Yes, as an open-access journal, we charge APCs to cover peer review, editing, production, and hosting costs. However, we offer waivers and discounts for researchers from low-income countries, unfunded studies, or exceptional circumstances. Financial constraints should never prevent publication of quality research - contact us to discuss waiver eligibility.
Can I suggest reviewers for my manuscript?
Yes, you may suggest up to 3 potential reviewers during submission. Please provide their full contact information and explain their expertise relevant to your manuscript. You may also request exclusion of specific reviewers with justification. While we consider suggestions, final reviewer selection rests with the handling editor to ensure independence and expertise.
What happens if my manuscript is rejected?
You will receive detailed feedback from reviewers and the editor explaining the decision. We provide constructive comments to help improve your work, whether for resubmission after major revisions or submission elsewhere. Rejected manuscripts can be appealed if you believe the decision was based on misunderstanding or factual errors.
Do you accept manuscripts previously posted as preprints?
Yes, we fully support preprint posting on servers like bioRxiv, medRxiv, or arXiv. Preprint posting does not affect consideration for publication in JHAI. Please disclose preprint posting during submission and provide the preprint DOI.
How do I track my manuscript status?
If you submitted via ManuscriptZone, log into your account for real-time status updates, reviewer comments, and editor decisions. If you used the Quick Submission Form, you'll receive email updates at each stage. You can always contact our editorial office for status inquiries.
What if I need to withdraw my manuscript?
You may withdraw your manuscript at any time before acceptance by contacting the editorial office. Please provide a brief explanation for the withdrawal. Once accepted, withdrawal is more complex and may require editor approval, especially if the manuscript is already in production.
