肺炎为临床最常见的感染性疾病,病原体中以细菌常见。随着各种高效抗生素早期、广泛地应用,典型的细菌性肺炎已越来越少见。而以轻型或不典型表现多见。尤其是一些年长患者,可完全无寒战、胸痛、咳嗽、血痰等症状。 Pneumonia is the most common infectious disease in clinical practice, and bacteria are common in pathogens. With a variety of highly effective antibiotics early, widely used, the typical bacterial pneumonia has become increasingly rare. And more common in light or atypical. In particular, some elderly patients can be completely chills, chest pain, cough, bloody sputum and other symptoms.
