Query: Urban contact structures for epidemic simulations: Correcting biases in
  data-driven approaches   Epidemics are emergent phenomena depending on the epidemiological
characteristics of pathogens and the interaction and movement of people. Public
transit systems have provided much important information about the movement of
people, but there are also other means of transportation (e.g., bicycle and
private car), that are invisible to public transit data. This discrepancy can
induce a bias in disease models that leads to mispredictions of epidemic growth
(e.g., peak prevalence and time). In our study, we aim to advance and compare
the epidemic spreading dynamics using public transit trips, in contrast to more
accurate estimates of population movement using mobile phones traces. In our
study, we simulate epidemic outbreaks in a cohort of two million mobile phone
users. We use a metapopulation model incorporating
susceptible-infected-recovered dynamics to analyze and compare different
effective contract matrices, constructed by the public transit systems and
mobile phones respectively, on the process of epidemics. We find that epidemic
outbreaks using public transit trips tend to be underestimated in terms of the
epidemic spreading dynamics, reaching epidemic peaks weaker and later. This is
rooted in a later introduction of new infectious people into uninfected
locations.
