Query: Incorporating Dynamic Flight Network in SEIR to Model Mobility between
  Populations   Current efforts of modelling COVID-19 are often based on the standard
compartmental models such as SEIR and their variations. As pre-symptomatic and
asymptomatic cases can spread the disease between populations through travel,
it is important to incorporate mobility between populations into the
epidemiological modelling. In this work, we propose to modify the commonly-used
SEIR model to account for the dynamic flight network, by estimating the
imported cases based on the air traffic volume as well as the test positive
rate at the source. This modification, called Flight-SEIR, can potentially
enable 1). early detection of outbreaks due to imported pre-symptomatic and
asymptomatic cases, 2). more accurate estimation of the reproduction number and
3). evaluation of the impact of travel restrictions and the implications of
lifting these measures. The proposed Flight-SEIR is essential in navigating
through this pandemic and the next ones, given how interconnected our world has
become.
