Superspreading Drives the COVID Pandemic–And Could Help to Tame It

February 23, 2021

(Nature) – As the pandemic enters its second year — a time marked by news of fast-spreading variants of the virus — researchers are now more convinced than ever of the importance of superspreading in how the COVID-19 pandemic has played out, and how it will do so in the future. They have found that superspreading events are one of the main ways in which SARS-CoV-2 has gained a foothold in communities around the world, so far infecting more than 100 million people and killing more than 2.4 million. Without effective control measures, superspreading events might even become larger and more frequent as more-transmissible variants first identified in the United Kingdom, South Africa and Brazil push out other strains of the virus.
