Hantaviruses are viruses belonging to the Bunyaviridae family, and they cause two forms of acute illness in humans: hemorrhagic fever with renal syndrome (HFRS) and hantavirus cardiopulmonary syndrome (HCPS). HFRS form seen in our country progresses with fever, acute kidney injury, thrombocytopenia and bleeding. Therefore, hantavirus infections should be kept in mind in the differential diagnosis of patients presenting with these symptoms and signs. This report presents a case followed up with the differential diagnosis of coronavirus disease-19 (COVID-19) during the pandemic and diagnosed with HFRS due to hantavirus.

Varicella zoster virus (VZV) is a member of the herpes virus family and is the causative agent of chickenpox and shingles. While chickenpox, which is the primary infection, is mostly seen in childhood, shingles is located latently in the dorsal root sensory ganglia and cranial nerve ganglia, causing recurrent attacks in adulthood. Shingles may rarely present with neurological complications such as encephalitis. Many diseases are seen in the coexistence of Coronavirus disease-2019 (COVID-19) due to the pandemic. In this case report, it was aimed to draw attention to the ophthalmic varicella zoster virus infection with a different clinical onset accompanied by COVID-19 who presented with the clinic of encephalitis.

Coronavirus disease 2019 emerged in China at the end of 2019 and spread worldwide. A sixty-three-year-old female patient was admitted to the hospital six days after she tested positive for SARS-CoV-2 with complaints of cough, shortness of breath, and myalgia. After seven days, both parotid gland sites developed swelling, tenderness, and pain. The ultrasonography revealed acute parotitis bilaterally. Viral serological tests were negative. Therefore, COVID-19 infection was considered the cause of acute parotitis. The patient was discharged after recovery. This case report emphasized that acute non-suppurative parotitis may develop due to COVID-19 infection as an atypical manifestation.
