ABSTRACT
Objectives: Coronavirus disease-2019 (COVID-19) caused a pandemic, which has been going on for about 1 year. How long the pandemic will continue remains uncertain. Determining the etiology of pneumonia is the most important point for the treatment approach. In this study, it was aimed to determine the parameters that might be useful in the differentiation of community-acquired pneumonia (CAP) from COVID-19 pneumonia. Materials and Methods: CAP group consisted of 53 people who applied to the infectious diseases polyclinic and chest diseases polyclinic between 01.12.2019 and 30.01.2020 in our country, including the periods when the incidence of CAP increased and influenza peaked, and were hospitalized after being diagnosed with pneumonia. For the COVID-19 pneumonia group, 37 patients with Severe Acute Respiratory Syndrome-Coronavirus-2 detected by polymerase chain reaction from the combined nasal throat swab and with computed tomography showing lesions consistent with COVID-19 were included.
