The burden of pneumonia, including that due to respiratory viruses, is markedly higher in the very young (<5 years) and older adults (≥50 years). Respiratory viruses substantially contribute to pneumonia in both adults and children, and when systematically tested for, are more commonly detected than bacteria in both adults and children. It is difficult to distinguish between viruses by clinical presentation, and the exact clinical implication of viral detections among patients with pneumonia depends on the pathogen detected; however, there is increasing evidence of their importance in pneumonia.
包括由呼吸道病毒引起的肺炎负担，在幼儿（<5岁）和老年人（≥50岁）中明显更高。呼吸道病毒在成人和儿童的肺炎发病中都起着重要作用，并且在对两者进行系统检测时，病毒的检出率比细菌更高。通过临床表现很难区分病毒种类，肺炎患者中病毒检测的具体临床意义取决于所检测到的病原体；然而，越来越多的证据表明它们在肺炎中具有重要性。
