Background Patients with COVID-19 most commonly report respiratory symptoms, with a minority reporting gastrointestinal (GI) symptoms in currently available reports. Additionally, little is known about the symptoms of anosmia/hyposmia, ageusia, and dysgeusia anecdotally seen in COVID-19 patients, which may be considered both GI and sensory/neurological manifestations of infection. Methods We interviewed 7 patients via oral inquiries and a questionnaire, collecting data on subject symptoms and their durations. Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to confirm 2 of these cases. Results We report a familial cluster of 7 COVID-19 cases, 5 of whom reported sensory symptoms of anosmia/hyposmia (5/7), ageusia/hypogeusia (5/7), and/or dysgeusia (3/7). All 7 cases reported GI involvement with one or more symptom of: nausea (5/7), diarrhea (4/7), abdominal pain (3/7), anorexia (3/7), and emesis (2/7). Figure 1. Timeline of Symptoms and Exposure to Index Case in Familial COVID-19 Cluster Conclusion This frequency of GI symptoms is high relative to currently available epidemiological reports, which also infrequently report on sensory symptoms. The mechanistic underpinnings of GI and sensory symptoms in COVID-19 warrant close consideration and analysis, especially as it relates to reducing disease transmission. COVID-19 exhibits wide variation in duration, severity, and progression of symptoms, even within a familial cluster. Disclosures All Authors: No reported disclosures
