A Case Report of Post-COVID-19 Eosinophilic Enteritis: An Uncommon Diagnosis in an Adult.

Eosinophilic esophagitis (EoE) and eosinophilic gastroenteritis (EGE), also known as eosinophilic enteritis (EoN), are both parts of the eosinophilic gastrointestinal disease (EGID) and share pathogenic similarities. Over the past two decades, the incidence and prevalence of EoE have rapidly increased, especially in Western countries, while EGE remains rare. Unlike EoE, no standard treatment strategies or guidelines have been established due to the extreme rarity of EGE, especially in Western countries. Here, we report a rare case of EoN in a 35-year-old female resulting from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.
