This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Viral infection due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) induce a dynamic immune environment. Using nasal mucosal samples in 139 participants from the STOIC study (community-based randomised clinical trial for the use of budesonide in early onset SARS-CoV-2, NCT04416399), we applied predefined immune mediator nodes in relation to clinical outcomes and viral burden. Interferon- and chemokine-dominant nodes increased expression as compared to health, validating our modular approach. Next, we demonstrated that an increase in mucosal immunity-like node consisting of CCL13, CCL17, IL-33, among others was associated with a mean 3.7-day quicker recovery with no primary outcome events, irrespective of treatment arm. By day 14 the mucosal node divided into two daughter nodes linked to interferon molecules and was transcriptionally detectable in nasal cavity basal, hillock and ciliated cells (as per public single cell dataset EGAD00001007718). Our data suggest mucosal-associated mediators are key for early symptom resolution of SARS-CoV-2.
