Although not everybody agrees: unlike the 1918 strain, these previous viruses did not cause aggressive bronchopneumonia nor lung haemorrhage.

和1918年株不同，以些不会引起侵袭性支气管肺炎或者肺出血。

In bronchopneumonia, the infection can be throughout the lungs involving the bronchioles as well as the alveoli.

在支气管肺炎，感染可以遍及肺部，包括细支气管和肺泡。

Not viruses this time, but bacteria: pathogens like Streptococcus Pneumoniae or Staphylococcus aureus would invade the damaged lungs, causing cases of aggressive bronchopneumonia.

次不，而细菌：肺炎链球菌或金黄色葡萄球菌等原体会侵入受损肺部，导致侵袭性支气管肺炎。

This time though it tends to cavitate or form cavities which can allow the bacteria to disseminate or spread through the airways and lymphatic channels to other parts of the lungs which can cause bronchopneumonia.

而此时就会形成一个空洞，或很多肺空洞，些空洞会使得细菌在气道内和淋巴管道内扩散到达肺部其它区域，可引起支气管肺炎。
