  We propose a risk measure and construct an infectious diseases hazard map for
India. Given an outbreak location, a hazard index is assigned to each city
using an effective distance that depends on inter-city mobilities instead of
geographical distance. We demonstrate its utility using an SIR model augmented
with air, rail, and road data between top 446 cities. Simulations show that the
effective distance from outbreak location reliably predicts the time of arrival
of infection in other cities. The hazard index predictions compare well with
the observed spread of SARS-CoV-2. The hazard map can be useful in other
outbreaks also.
