Fourty-nine years old woman co-infected with SARS-CoV-2 and Mycoplasma: A case report

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new virus responsible for the outbreak of respiratory illness known as coronavirus disease 2019 (CoVID-19). Mycoplasma is an uncommon co-infected pathogen with SARS-CoV-2 and has not yet been reported. Computed tomography (CT), used as an accessory examination, may play a more significant role in this co-infection.

A 49-year-old female presented with a cough, expectoration and chest congestion followed by elevated C-reactive protein and erythrocyte sedimentation rate. CT images showed ground-glass opacities in bilateral lower lobes and a patchy and striate shadow in the right upper lobe. Immunoglobulin M antibody of Mycoplasma pneumoniae was positive and real-time fluorescence polymerase chain reaction of sputum was positive for SARS-CoV-2 nucleic acid. The diagnosis of CoVID-19 was made based on laboratory results, chest CT images, clinical manifestations and epidemiologic characteristics. She was treated with combination therapy for 17 d and showed a marked reCoVery.

Co-infection with SARS-CoV-2 and Mycoplasma in CoVID-19 patients appears to be uncommon. CT is an acceptable method for the primary diagnosis and treatment should be initiated as soon as possible. Combination therapy with antiviral, anti-inflammatory, traditional Chinese herbal medicine and interferon inhalation may be a reference for further progress in treating this co-infection.
