Limited Temporary Effect of Several Social Relaxation Events on the COVID-19 Series: An Analysis Based on Primary Data
Journal Title: Journal of Clinical Immunology & Microbiology - Year 2021, Vol 2, Issue 2
Abstract
The relaxation of restrictive measures imposed by the COVID-19 pandemic allowed a gradual resumption of human activities, although the influence of each measure on the COVID-19 series is not consensual. We analyzed the effects of sequential reopening events during COVID-19 pandemic based in 76,419 SARS-CoV-2 RT-PCR tests performed from April 2020 to January 2021 in Rio de Janeiro metropolitan area, Brazil. A statistically significant increase in cases after 3-4 weeks of reopening measures, followed by a drop for a similar period, indicated that such events resulted in temporary and non-cumulative effects. A second peak in November was preceded by measures of social relaxation of a high level of agglomeration in confined spaces, including an election campaign. Post-opening events provoked different impacts on cases, but showing limited temporary effect. It is possible that other factors, including the exhaustion of social distancing and the appearance of new SARS-CoV-2 strains may have also influenced this second wave.
