Cell Host & Microbe 'Under Review': What Each Status Means

Before the paper reaches external reviewers, a Cell Press consulting editor at Cell Host & Microbe evaluates whether the host-microbe mechanism warrants Cell Host & Microbe's selective editorial slots. About 70 percent of submissions are returned at this stage within 3 days per Cell Press journal-insights data. A desk rejection most often means the consulting editor concluded that the work would fit better at a sister Cell Press title (Cell Reports, iScience, Cell Reports Medicine) or that the cross-system validation expected for Cell Host & Microbe is missing.

The Cell Press editorial office confirms files are complete: manuscript with figures embedded, supplementary information separate, reporting checklists where applicable (ARRIVE for animal work, MIQE for quantitative PCR, STROBE for observational human microbiome studies), STAR Methods compliance documentation, cover letter directed to the editor, conflict-of-interest declarations, and ethics-statement documentation.

The consulting editor reads the paper and evaluates host-microbe mechanism depth, scope fit, and whether cross-system validation supports the central claim. Most rejections happen here within 3 days per Cell Press editorial-speed data.

In parallel with the consulting editor's primary read, ambiguous-fit papers are discussed at the Cell Press editor meeting where peer consulting editors at sister Cell Press titles weigh in on whether the paper would fit better at Cell Host & Microbe, Cell Reports, or iScience. This editorial-team discussion runs alongside the desk-screen and adds 1 to 3 days to the front-end timeline that is invisible to the author in the portal.

Cell Press consulting editors at Cell Host & Microbe typically invite two to three external reviewers. The recruitment window can take 7 to 14 days because host-pathogen reviewers with cross-system expertise (e.g., bacterial pathogenesis + immunology, viral mechanism + clinical translation) are scarce. Reviewer invitations from Cell Press are weighted higher than most Elsevier titles in reviewers' personal triage queues.

Once reviewers agree to review, the typical Cell Host & Microbe peer-review cycle lasts 21 to 35 days. Reviewers are asked to evaluate mechanism depth, cross-system validation, in-vivo or clinical translation, and reproducibility. Reviewer reports for Cell Host & Microbe tend to be thorough; 2000 to 3500 word reports are typical.

After both reports return, the consulting editor synthesizes them. The 77 day submission-to-acceptance average per Cell Press journal-insights data applies to papers that reach external peer review and successfully complete revisions.

• Rejection within 1 to 3 days: Administrative issue or immediate scope mismatch.
• Rejection within 3 to 7 days: Consulting editor desk rejection. Most rejections happen here.
• Still Under Review after 2 weeks: Strong signal. Paper passed the steepest Cell Press filter.
• Still Under Review after 10 weeks: Reviewer-recruitment or reviewer-report delay. A polite inquiry to chom@cell.com is appropriate.
• Status changes to "Decision Pending": Reports are in; expect a decision within 1 to 2 weeks.

This is the most common anxiety we hear from Cell Host & Microbe authors during the active editorial window. The honest answer: no, 5 weeks at Under Review is the normal middle of the Cell Press distribution. Cell Host & Microbe's 4 to 8 week external-review window means 5 weeks puts you exactly mid-cycle. Most reviewer-driven delays come from reviewer-recruitment timing, especially for host-pathogen reviewers with cross-system expertise. Once a reviewer accepts the assignment, reports typically arrive within 21 to 28 days at Cell Press journals. If the portal still says Under Review at the 7-week mark, the most likely explanation is reviewer extension granted by the consulting editor. This is normal practice at Cell Press.

What you should NOT do during the 5-to-7-week window is email the editorial office. Cell Press consulting editors at Cell Host & Microbe are managing 40+ active papers; an inquiry at 5 weeks adds friction without accelerating the timeline.

If your Cell Host & Microbe paper is rejected after review, the natural cascade depends on what the reviewers and consulting editor cited:

Cell Reports is the most natural Cell Press cascade because Cell Press editors transfer manuscripts directly via the portable peer-review system, preserving reviewer reports for the receiving editor. Cell Reports has a broader scope and a slightly lower cross-system validation requirement. The transfer process takes 5 to 10 days because Cell Press carries the reviewer reports across.

PLOS Pathogens is a secondary cascade option for mechanism-focused host-pathogen papers where the open-access publishing model is preferred. PLOS Pathogens has a comparable mechanism-depth bar but operates a standard double-blind peer review.

Nature Microbiology is a cascade option for papers where the broader microbiology framing is stronger than the host-pathogen specificity, particularly for microbiome-focused work.

Cell Press asks reviewers at Cell Host & Microbe to evaluate four things specifically. The table below maps each to actionable preparation.

Three patterns generate the most consistent reviewer concerns we see at Cell Host & Microbe.

Single-pathogen mechanistic claims without cross-system validation. When the central host-microbe mechanism is demonstrated in only one pathogen or one microbiome context, reviewers consistently request demonstration in at least one additional system. Cell Press's editorial-speed data explicitly flags this as a common revision driver.

In-vitro-only studies lacking in-vivo or clinical translation. When the mechanism is established only in cell-culture systems without animal model or clinical-sample validation, reviewer consultation often extends. The strongest revisions add in-vivo perturbation phenotyping or patient-cohort microbiome correlation data.

Cell Press venue mismatch flagged by consulting editor. When the consulting editor concludes the work is sound but the host-microbe specificity is narrower than Cell Host & Microbe's bar, transfer offers to Cell Reports, iScience, or Cell Reports Medicine are common. Cell Press editors take these transfers seriously.

This page was created from Cell Press's public author guidance at cell.com/cell-host-microbe/authors, Cell Press Editorial Manager documentation, Cell Press journal-insights desk-decision and time-to-acceptance data, and Manusights pre-submission review experience with Cell Host & Microbe-targeted manuscripts. Numeric claims about desk-decision and review-time windows are sourced to Cell Press editorial speed metrics.

For the Cell Press host-microbe landscape beyond Cell Host & Microbe, see Cell Reports (broader scope, faster turnaround, Cell Press portable peer-review transfer), iScience (open-access alternative across Cell Press), and Cell Reports Medicine (clinical-translation focus). The choice across these titles depends on whether the central contribution is host-microbe-mechanism-with-cross-system (Cell Host & Microbe), broader cell-biology (Cell Reports), open-access (iScience), or clinical-translation (Cell Reports Medicine). For technical issues during Cell Press submission, the editorial office at chom@cell.com handles most queries via the manuscript record.

Reviewers at Cell Host & Microbe typically draw from one mechanism-focused host-pathogen expert and one broader microbiology or immunology specialist. Preparing a response template that addresses both perspectives accelerates revision rounds substantially.
