Diagnosis of lung diseases is difficult, especially during an epidemic, with a large number of patients and a limited time for diagnosis.

The purpose — to evaluate the results of differential diagnosis of lung diseases and the outcome of the disease in patients with suspected coronavirus pneumonia COVID-19 and pulmonary tuberculosis.

Material and methods. We analyzed 705 records of patients admitted to the Tuberculosis Dispensary with suspected tuberculosis and coronavirus pneumonia during the COVID-19 pandemic.

Results. It is difficult to establish the disease etiology by evaluating complaints and X-ray, especially against the background of HIV infection. We assessed the proportion of isolated viral pneumonia, bacterial-viral pneumonia, combination of viral pneumonia with pulmonary tuberculosis, both with and without the presence of HIV infection. Evaluation of the immune status of patients with HIV infection and laboratory diagnostics made it possible to suspect and identify pneumocystosis of the lungs. The outcome in each category of patients was analyzed. Significant criteria for the development of an unfavorable outcome of coronavirus pneumonia were obtained.

Conclusion. Each patient with a suspected diagnosis of pneumonia needs high-quality and timely diagnostics to verify the infectious agent of the lungs and assess the patient’s HIV status.

Key words: coronavirus pneumonia COVID-19, pneumocystis pneumonia, pulmonary tuberculosis, bacterial-viral pneumonia, HIV infection.
