We develop an agent-based model of disease transmission in remote communities in Western Australia. Despite extreme isolation, we show that the movement of people amongst a large number of small but isolated communities has the effect of causing transmission to spread quickly. Significant movement between remote communities, and regional and urban centres allows for infection to quickly spread to and then among these remote communities. Our conclusions are based on two characteristic features of remote communities in Western Australia: (1) high mobility of people amongst these communities, and (2) relatively high proportion of travellers from very small communities to major population centres. In models of infection initiated in the state capital, Perth, these remote communities are collectively and uniquely vulnerable. Our model and analysis does not account for possibly heightened impact due to preexisting conditions, such additional assumptions would only make the projections of this model more dire. We advocate stringent monitoring and control of movement to prevent significant impact on the indigenous population of Western Australia.
There is a continuing debate on relative benefits of various mitigation and suppression strategies aimed to control the spread of COVID-19. Here we report the results of agent-based modelling using a fine-grained computational simulation of the ongoi
In late 2019, a novel coronavirus, the SARS-CoV-2 outbreak was identified in Wuhan, China and later spread to every corner of the globe. Whilst the number of infection-induced deaths in Ghana, West Africa are minimal when compared with the rest of th
Some of the key questions of interest during the COVID-19 pandemic (and all outbreaks) include: where did the disease start, how is it spreading, who is at risk, and how to control the spread. There are a large number of complex factors driving the s
As of July 2021, there is a continuing outbreak of the B.1.617.2 (Delta) variant of SARS-CoV-2 in Sydney, Australia. The outbreak is of major concern as the Delta variant is estimated to have twice the reproductive number to previous variants that ci
The spread of an epidemic process is considered in the context of a spatial SIR stochastic model that includes a parameter $0le ple 1$ that assigns weights $p$ and $1- p$ to global and local infective contacts respectively. The model was previously s
