It has been apparent since the start of the Covid-19 pandemic that certain people are responsible for spreading more than their share of infections.

Back in January, before it was officially declared a pandemic -- when roughly 500 people were believed to be infected and fewer than 20 had died -- one patient in Wuhan, China, reportedly spread the disease to 14 health care workers. More recently, in March, a single member of a choir in Washington state was found to have infected 52 others during a 2 1/2-hour practice session. And in early May, after South Korea began to relax social-distancing restrictions, dozens of new infections emerged around Seoul; the cluster was linked to a 29-year-old man who tested positive after visiting five nightclubs and bars in one night.

These people have been called "super spreaders," but are they really different from the rest of us?
