| Abstract | All South American countries from the Southern cone (Argentina, Brazil, Chile, Paraguay and
Uruguay) experienced severe COVID-19 epidemic waves during early 2021 driven by the expansion of
variants Gamma and Lambda, however, there was an improvement in di erent epidemic indicators since
June 2021. To investigate the impact of national vaccination programs and natural infection on viral
transmission in those South American countries, we analyzed the coupling between population mobility
and the viral e ective reproduction number Rt. Our analyses reveal that population mobility was highly
correlated with viral Rt from January to May 2021 in all countries analyzed; but a clear decoupling
occurred since May-June 2021, when the rate of viral spread started to be lower than expected from the
levels of social interactions. These ndings support that populations from the South American South-
ern cone probably achieved the conditional herd immunity threshold to contain the spread of regional
SARS-CoV-2 variants. | pt_BR |
