| Abstract | The ongoing pandemic of 2019-nCov (COVID-19) coronavirus has made reliable epidemi-ological modeling an urgent necessity. Unfortunately, most of the existing models are eithertoo fine-grained to be efficient or too coarse-grained to be reliable. Here we propose acomputationally efficient hybrid approach that uses SIR model for individual cities whichare in turn coupled via empirical transportation networks that facilitate migration amongthem. The treatment presented here differs from existing models in two crucial ways: first,self-consistent determination of coupling parameters so as to maintain the populations ofindividual cities, and second, the incorporation of distance dependent temporal delays inmigration. We apply our model to Indian aviation as well as railway networks taking intoaccount populations of more than 300 cities. Our results project that through the domestictransportation, the significant population is poised to be exposed within 90 days of the onsetof epidemic. Thus, serious supervision of domestic transport networks is warranted evenafter restricting international migration. |
