COVID-19 in Brazil: Spatial Patterns and Demographic Effects
Marcia C. Castro
Online Presentation, September 30, 2021
As part of the Suessmilch Lecture series, Marcia C. Castro from Harvard University, Harvard T.H. Chan School of Public Health, Boston gave a talk on COVID-19 in Brazil.
“COVID-19 in Brazil: Spatial Patterns and Demographic Effects”
Brazil has been severely hit by COVID-19, with rapid spatial spread of both cases and deaths. Indicators of clustering, trajectories, speed, and intensity of the movement of COVID-19 to interior areas, combined with indices of policy measures show that while no single narrative explains the diversity in the spread, an overall failure of implementing prompt, coordinated, and equitable responses in a context of stark local inequalities fueled disease spread. This resulted in high and unequal infection and mortality burdens, with large reductions in life expectancy. We estimate a decline in 2020 life expectancy at birth (e0) of 1.3 years, a mortality level not seen since 2014. The loss was not uniform among states; Amazonas lost 60.4% of the improvements in e0 since 2000. In the first four months of 2021, COVID-19 deaths represented 107% of the total 2020 figures. Assuming that death rates would have been equal to 2019 all-cause rates in the absence of COVID-19, COVID-19 deaths in 2021 have already reduced e0 in 2021 by 1.8 years, which is slightly larger than the reduction estimated for 2020 under similar assumptions.
