Comparison between the two largest neighboring states in Brazil, Amazonas and Pará, showing more than 5 times lower mortality in Pará during the second wave when the Pará government supported early treatment and Amazonas did not, compared to similar results in the first wave when treatment protocols were similar.

Comparisons between the
Neighboring States of Amazonas
Abstract: Brazil and many countries are now experiencing a second wave of the COVID-19 outbreak. The objective of this study is to compare results with statistical samples involving millions of
people in the two largest neighboring states in Brazil, Amazonas and Pará, which in the first wave
were similar but now show significant different results in combating COVID-19. During the first
wave, in May 2020, the maximums of the 7-day average daily deaths per population of Amazonas
and Pará were similar: 15.7 and 17.1 deaths per day per million people, respectively, which means
a ratio 15.7/17.1 = 0.92 ≈ 1. Now, in the second wave of COVID-19 outbreak, Amazonas has entered
a serious situation; meanwhile, Pará has presented a much smaller growth in the mortality. The
accumulated mortality per population from 11 November 2020 to 15 March 2021 of Amazonas and
Pará are 1645 and 296 deaths per million people, respectively. As 1645/296 = 5.55, Amazonas is presenting an accumulated mortality per population more than five times that of Pará. Future in-depth
research can provide a grounded answer to explain this significant difference, nonetheless the explicit support of the Pará state government, after 21 May 2020, to early ambulatory treatment may
have played some role on this result.
