Description
Summary:[...]although there was no correlation between the presence of the Omicron variant and daily new deaths, these also increased during this fourth wave of COVID-19 (r = 0.1154, P = 0.3638). 2,6 Nevertheless, the deaths observed through this fourth wave were lower in comparison with those reported during the third wave triggered by the Delta variant, which also had fewer deaths when compared to the second wave. [...]although the number of daily new cases has increased with each new wave, the number of deaths has also decreased at the same time (Figure 1). Reports of daily new cases (a) and deaths (b) were obtained from Johns Hopkins University & Medicine Coronavirus Resource Center. 2 Proportions of vaccinated people (indicated by dashed lines) were obtained from Our World in Data. 7 Only in the text we show the Pearson´s correlation coefficient to test the association between the proportion of reported sequences of the Omicron variant with daily new cases and daily new deaths, from the beginning to the peak of the fourth COVID-19 wave.
