=== Pathology ===
The main pathological findings at autopsy are:
* [[macroscopic scale|Macroscopy]]: [[pericarditis]], [[lung consolidation]] and [[pulmonary edema|pulmonary oedema]]<ref name="Cureus" />
* Lung findings:
** minor serous [[Exudate|exudation]], minor [[fibrin]] exudation<ref name="Cureus" />
** pulmonary oedema, [[pneumocyte]] [[hyperplasia]], large atypical [[pneumocyte]]s, interstitial [[inflammation]] with [[lymphocytic]] [[Infiltration (medical)|infiltration]] and [[giant cell|multinucleated giant cell]] formation<ref name="Cureus" />
** [[diffuse alveolar damage]] (DAD) with diffuse [[Pulmonary alveolus|alveolar]] [[exudates]]. DAD is the cause of [[acute respiratory distress syndrome]] (ARDS) and severe [[hypoxemia|hypoxaemia]].<ref name="Cureus" />
** [[healing|organisation]] of [[exudate]]s in [[Pulmonary alveolus|alveolar cavities]] and [[Pulmonary fibrosis|pulmonary interstitial fibrosis]]<ref name="Cureus" />
