Superspreading drives the COVID-19 pandemic, study finds

Researchers at HKU SPH have investigated the effects of superspreading (situations where one person with an infection passes on the infection to many people) on the spread of COVID-19 in Hong Kong, revealing the phenomenon as one of the drivers of the COVID-19 pandemic. In this study, researchers used contact tracing data from just over 1,000 SARS-CoV-2 cases confirmed between 23 January and 28 April 2020 in Hong Kong and estimated that 19% of cases were the source of 80% of all locally transmitted cases. This indicates that contact tracing efforts to find clusters of cases and superspreading events may have the most impact on the control of COVID-19 spread in Hong Kong.
