Resumen:

We present two modeling ideas that aim at describing and understanding the effects and evolution of the COVID-19 pandemic in Mexico. First, a new and straightforward statistical methodology is proposed to model epidemic curves. The key here is to assume that the times when a certain number of infected individuals are observed have been censored, but follow a known probability distribution; the censorship point is the most recent date for which a record is available. The second idea exploits the information of patients identified as SARS-CoV-2 positive in Mexico to understand the relationship between comorbidities, symptoms, hospitalizations, and deaths due to the COVID-19 disease. Using the presence or absence of these latter variables, a clinical footprint for each patient is created. The proposal considers all possible footprint combinations resulting in a robust model suitable for Bayesian inference. © 2023 Elsevier B.V. All rights reserved.
