Summary:On January 30, 2020, the World Health Organization (WHO) declared SARS-CoV-2 infection an international public health emergency. The autopsy, considered the best method of studying the patient and the disease, corroborates that patients can die from the direct action of the virus (who died from COVID-19), while others positive for SARS-CoV-2 did not show morphological lung changes attributed to the action of the virus. It is proposed to establish the morphological diagnostic criteria in the context of the SARS-CoV-2 and COVID-19 epidemic in the deceased in Cuba based on the systematic study of autopsies. The morphological patterns that are established in the lungs of patients who died under the effect of COVID-19 have been identified. The pulmonary edema of permeability with the widening of the pulmonary septum, the deposit of the disorganized hyaline membrane inside the alveoli, the detachment of epithelial cells (pneumocytes and bronchial and bronchiolar cells), followed by epithelial hyperplasia with sometimes the presence of metaplastic changes and atypia, and finally, fibrosis. When autopsies are performed, it is possible to locate each disease in its place, in chronopathogram, which allows death certificates repair to be carried out to assess the place that COVID-19 has occupied as a cause of death in the population studied. In the opinion of the group, identifying morphological alterations is essential to prepare the chronopathogram of the deceased and the adequate clinical-pathological evaluation of the patient.
