ABSTRACT
Current knowledge about the COVID-19 pandemic is still limited, especially in the pediatric age group. So far, children are considered to be a minimally affected population;however, physicians from different parts of the world have recognized a new pediatric multi-systemic inflammatory syndrome, that provokes a multiple organ dysfunction, from which the heart is not exempted. The direct action of the virus on myocardial cells, as well as the cytokines storm -triggered by the infection- are responsible for the myocarditis developed in these patients. In this article a case with criteria of myocarditis associated with COVID-19 is described. Achieving an early diagnosis ofmyocarditis secondary to SARS-CoV-2 infection in the current epidemiological context allows a correct and timely therapeutic approach, avoiding the torpid evolution and fatal outcome of this disease, as well as other long-term complications.
ABSTRACT
Health disasters have affected humanity since its dawn. In other epidemics, the casualties caused number in the hundreds of thousands. The preparation for confronting the COVID-19 epidemic at the Military Hospital of Matanzas, "Dr. Mario Muñoz Monroy”, began early. In order to analyze this experience, we reflect on the results of the confrontation in 2020, based on the main aspects, the coordination with other organizations, the decisions made, structural changes and modifications of institutional processes. Consolidating scientific improvement has been a permanent pillar, along with discipline, personal and social responsibility of the members of the collective. © 2023, Editorial Ciencias Medicas.

ABSTRACT
The basic SIR (Susceptible-Infected-Recovered) model of Kermack-McKendrick is a compartmental model in which the population under study is divided into epidemiological classes, in between which a flow is described. A robust health system that provides reliable data to the model and combined with coherent public health policies contributes to controlling the impacts of epidemic contingencies. Hence, the objective of this study is to apply the SIR model, without delving into the mathematical apparatus that accompanies it, to know the impact of COVID-19 in Cuba, with an emphasis on Havana, as the center of the epidemic in the country in the period from March 11 to July 16, 2020. To do this, the model is shown with variable coefficients over time, together with its usefulness as a dynamic model to make projections in epidemic situations. It is applied to specific local regions and its potentialities to analyze outbreaks are manifested by the onset of local events that are far from the foreseen predictions. This work is part of the efforts that, in all orders, the Cuban Ministry of Public Health has developed to confront the COVID-19 pandemic.
