Overdispersion is a manifestation of scale-free networks, where most of the traffic goes through a relatively small number of nodes (everyone is 6 steps from everyone else). I'm pessimistic that the super-spreaders can be identified. Some of the super-spreading may be inherent in the individual (someone who has a high concentration of active virus in the saliva, and exhales a large number of air-borne particles), but it will be hard to identify these people in a timely manner, and even if we did, there will be other factors that aren't specific to particular individuals, but rather the environment. Obviously, to have a super-spreading event, you have to have a large concentration of people in one place. A person with the potential to spread the virus to many people can't realize that potential unless s/he is in a crowd, or as the article suggests, has close contact with a large number of people in a relatively short time.
All we can do is keep hammering home the basic steps: masks, social distancing, avoid contact with others indoors, and so on. But now the President has called Fauci an idiot, and says that Americans are tired of the pandemic, and want to move on. It really looks as though cases, and eventually deaths, are going to continue to climb as we head into winter.
