Epidemiology: Dimensions of superspreading
Alison P. Galvani1 & Robert M. May2
Abstract
Analyses of contact-tracing data on the spread of infectious disease, combined with mathematical models, show that control measures require better knowledge of variability in individual infectiousness.
The SARS epidemic was notable for the existence of 'superspreaders' who infected dozens of people, whereas other infectious individuals infected few or none. Were SARS superspreaders anomalies, or are superspreaders characteristic of most infectious diseases?
