Before revision: Network scientists  proposed that infectious diseases  may be effectively halted by targeting interventions at a minority of highly connected individuals , or hubs . Can this strategy be effective in combating a disease transmitted through physical proximity such as SARS-CoV-2  ? Effectiveness critically depends on high between-person variability in the number of close-range contacts.
