Long COVID presenting with intermittent fever after COVID-19 pneumonia

Abstract

A 72-year-old man presented to our hospital with a fever. Chest computed tomography showed typical coronavirus disease 2019 (COVID-19) pneumonia. The fever normalized after a few days, and the pneumonia was alleviated. However, the intermittent fever subsequently re-occurred and persisted for over a month. Various tests, including blood tests, culture tests, and image evaluations, were performed. However, the conclusion was that long COVID was the cause of the intermittent fever as an exclusion diagnosis. Many patients suffer from persistent symptoms of COVID-19, but the symptoms and their durations vary. Here we report a case of prolonged fever after COVID-19 pneumonia.
