Persistent Hiccups as an Atypical Initial Presentation of COVID-19: A Case Report

SARS-CoV-2 is a novel coronavirus that causes acute respiratory syndrome in humans. It is also known as COVID-19 and was first discovered in Wuhan, Hubei Province in China in December 2019 and soon became a global pandemic. The common symptoms of COVID-19 include fever, fatigue, and dry cough; however, there are some atypical symptoms that remain either unreported or underreported.

In this case report, we described a 48-year-old diabetic man who presented with the chief complaint of persistent hiccups (<48h) to the emergency room with no history of malignancy, GI, cardiovascular, or neurological diseases. The patient also mentioned intermittent cough and mild dyspnea initiated the morning of admission day. On physical examination, other than mild tachycardia and tachypnea, there were no notable findings. Following an abnormal chest X-Ray, a chest CT scan was carried out, and peripheral ground-glass opacities along with scattered round opacities were identified in both lungs' fields. Given the strong suspicion of COVID-19, an RT-PCR test was performed, and the symptomatic treatment was initiated. The patient was diagnosed with COVID-19 following the PCR result release. The treatment was initiated per the protocol, and the patient was transferred to the isolated room and discharged after four days following the relief of the symptoms.

It is critical for medical practitioners to seriously consider the possibility of COVID-19 in a patient with similar presentations and isolate the patient at the asymptomatic stages to eliminate the possibility of virus transmission.
