Abstract

This article analyzes the growth and first category rates of contagion, lethality and mortality of COVID-19 in Mexico. The axis of this research postulates that the greater the number of vaccines applied against COVID-19, there must be a sustained decrease in transmissibility and deaths from this pandemic. This review was made from three moments in time, which allows knowing what happened before and after the application of the vaccines in Mexico. We worked with the Open Data base of the General Directorate of Mexican Epidemiology. To calculate the first category rates, the 2010 and 2020 Population and Housing Census and the 2015 Intercensal Survey of the Instituto Nacional de Geografía y Estadística (Inegi) were required. To identify the impact of comorbidities, a binomial logistic regression was performed, which allowed estimating probabilities of death in each of them. Among the results, it is observed that, after the start date of immunizations, the contagion, lethality and mortality rates of COVID-19 in the Mexican context presented a significant decrease, which demonstrates the effectiveness of immunization. Another important fact is that the binomial logistic regression showed that comorbidities continue to generate a greater propensity to die in people who suffer from them and become infected with COVID-19.
