Abstract

Background

Gastrointestinal (GI) symptoms are recognized sequelae of acute respiratory illness (ARI), but their prevalence is not well documented. Our study aim was to assess the incidence of GI symptoms in community ARI cases for persons of all ages and their association with clinical outcomes.

Methods

We collected mid-nasal swabs, clinical, and symptom data from Seattle-area individuals during the 2018–2019 winter season as part of a large-scale prospective community surveillance study.

Swabs were tested by polymerase chain reaction (PCR) for 26 respiratory pathogens. Likelihood of GI symptoms given demographic, clinical, and microbiological covariates were analyzed with Fisher’s exact, Wilcoxon-rank-sum, and t-tests and multivariable logistic regression.

Results

In 3183 ARI episodes, 29.4% had GI symptoms (n = 937). GI symptoms were significantly associated with pathogen detection, illness interfering with daily life, seeking care for the illness, and greater symptom burden (all p < 0.05). Controlling for age, > 3 symptoms, and month, influenza (p < 0.001), human metapneumovirus (p = 0.004), and enterovirus D68 (p = 0.05) were significantly more likely to be associated with GI symptoms than episodes with no pathogen detected. Seasonal coronaviruses (p = 0.005) and rhinovirus (p = 0.04) were significantly less likely to be associated with GI symptoms.

Conclusion

In this community-surveillance study of ARI, GI symptoms were common and associated with illness severity and respiratory pathogen detection. GI symptoms did not track with known GI tropism, suggesting GI symptoms may be nonspecific rather than pathogen-mediated. Patients presenting with GI and respiratory symptoms should have respiratory virus testing, even if the respiratory symptom is not the primary concern.
