Global Spread of Infectious Diseases

TL;DR

This paper presents simple models to understand how infectious diseases spread globally, focusing on air travel and regional health infrastructure differences, with formulas linking infection metrics to travel and epidemiological factors.

Contribution

It introduces new formulas connecting travel rates and regional health parameters to infection spread, enhancing understanding of global disease dynamics.

Findings

Formulas relating travel and health infrastructure to infection peaks.

Insights into how human mobility influences disease spread.

Framework for predicting infection numbers based on regional data.

Abstract

We develop simple models for the global spread of infectious diseases, emphasizing human mobility via air travel and the variation of public health infrastructure from region to region. We derive formulas relating the total and peak number of infections in two countries to the rate of travel between them and their respective epidemiological parameters.
