Black Lives Matter protests and COVID-19 cases: relationship in two databases

Area of Science:

• Epidemiology
• Public Health
• Sociology

Background:

• The convergence of Black Lives Matter (BLM) protests and the COVID-19 pandemic in the US prompted concerns regarding the public health implications of mass political gatherings.
• This study investigated potential correlations between large-scale political demonstrations and subsequent increases in COVID-19 transmission rates.

Purpose of the Study:

• To analyze the relationship between Black Lives Matter (BLM) protests and COVID-19 case rates in the United States.
• To assess the public health impact of mass gatherings during the pandemic.

Main Methods:

• Cross-referencing a BLM protest database with county-level COVID-19 data.
• Comparing COVID-19 case rates in protest-involved counties with matched control counties at 0, 1, 2, and 3 weeks post-protest.
• Utilizing regression analysis to quantify the impact of individual protestors on case rates.

Main Results:

• Over 868 protests involving an estimated 757,077 participants occurred across 326 counties within 22 days of George Floyd's killing.
• A statistically significant, albeit small, increase in the median COVID-19 case rate was observed in protest counties by Week 3 compared to control counties.
• Individual protestor contribution to the case rate was not statistically significant.

Conclusions:

• The observed increase in COVID-19 cases following BLM protests was statistically significant but minimal in magnitude.
• Methodological limitations, including differences in population sizes between protest and control counties, may have influenced the findings.
• Further research is needed to definitively establish causality and understand the nuanced relationship between political gatherings and disease transmission.
