It's important to understand how networks function because, as Watts puts it, «that has relevance to just
about every question we're interested in, whether we're talking
about the
spread of epidemics, or changes in social norms, or fashions, or the expression of the
genome.»
Sequencing virus
genomes from even a fraction of people infected in an epidemic and comparing mutation patterns can give researchers valuable information
about how big the epidemic is, how long it has been
spreading and where transmissions chains start and end, said Dr. Trevor Bedford, a Fred Hutch evolutionary biologist and one of the paper's authors.
