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

## TL;DR

This paper presents a rare case of a gastrointestinal condition in an adult linked to a previous COVID-19 infection.

## Contribution

The novelty lies in reporting a rare case of eosinophilic enteritis in an adult following SARS-CoV-2 infection.

## Key findings

- A 35-year-old female developed eosinophilic enteritis after a SARS-CoV-2 infection.
- Eosinophilic enteritis remains rare and lacks standardized treatment guidelines.

## Abstract

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.
