Summary#
This paper explores the phenomenon of superspreading events in the SARS-CoV-2 (COVID-19) pandemic through a systematic review and meta-analysis. It found that a majority of studies reported lower than one for the dispersion parameter k, indicating significant heterogeneity in inter-individual transmission potential.
Key Findings#
- Mean k estimates ranged from 0.04 to 2.97 across 28 peer-reviewed studies.
- 93% of the studies reported mean k estimates lower than one, indicating marked heterogeneity in inter-individual transmission potential.
- Recommended control measures included forward and backward contact tracing, timely case confirmation, rapid isolation, vaccination, and preventive measures to suppress superspreading.
Methodology#
- Study Type: Systematic Review and Meta-Analysis
Topics#
SARS-CoV-2, COVID-19, Superspreading, Overdispersion
Relevance#
The findings of this paper highlight the importance of understanding and addressing superspreading events in preparing for future pandemics.
