Patients will undergo routine clinical examination including lung auscultation with conventional stethoscope and LungPass device. Moreover, symptoms and anamnesis data, result of diagnostic questionnaire from the LungPass App, complete blood count, C-reactive protein, procalcitonin (PCT) level, SARS-CoV-2 PCR test and X-ray chest examination or CT chest (in case of preliminary clinical suspicion of LRTI).
