The current study stems from the need to understand associations between ABO\/Rh blood groups and COVID-19 in a temporal analysis. The preliminary results indicated that correlations change statistically as the pandemic extends and the time of exposure to the SARS-CoV-2 increases. A strong maximum correlation was obtained for blood groups A, O, A-, O-, Rh- and blood group A correlations were higher than those of the O blood group during most of the study period. Correlations of the blood type Rh-negative remained greater than those of the blood type Rh-positive throughout the 166-day period. With these studies it was possible to interpret the temporal evolution of the pandemic from the perspective of the correlation coefficients, here modeled by degree 11 polynomials using the least squares method. In addition, the behavior of the temporal evolutions of the correlations suggested studies on the total number of daily deaths, so rates of establishment of the pandemic COVID-19 and characterization parameters were proposed.<\/p><\/blockquote>\n\n\n\n<p><strong>A part of the highlights regarding Rh negative blood:<\/strong><\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>The relationship found between the Rh blood groups (Rh+ and Rh-) with the greatest correlations in the temporal Analyses 1-3 of the blood type Rh- suggests the need to proceed with studies in this direction.
