Earlier research in epidemiology and pathology assumed that each infected individual had an equal potential to spread disease to others.
However, in recent research, we have seen the 20/80 rule emerging. This rule shows that a minor percentage of individuals have an impact on most disease transmissions.
The individuals who can infect more secondary contacts than the average infected person are called super spreaders. They have been studied in light of the recent SARS and COVID-19 breakouts and present a complex picture of coinfections, hospital transfers, and immunity.
Understanding and predicting these super spreaders and super spreading events has been challenging, but it has led to an efficient response to the rapid spread of infectious diseases.
