CNN –  “This is the largest contact-tracing study in the world, and by a long shot,” Dr. Laxminarayan said. “We were surprised to find that just 8% of the infected primary cases were responsible for 60% of the contacts that were infected,” he said. “That’s a hugely disproportionate effect. Superspreading has been suspected, but not really documented.”
