The impact of re-opening the international border on COVID-19 hospitalisations in Australia: a modelling study.

ABSTRACT:

Objective

To estimate the numbers of COVID-19-related hospitalisations in Australia after re-opening the international border.

Design

Population-level deterministic compartmental epidemic modelling of eight scenarios applying various assumptions regarding SARS-CoV-2 transmissibility (baseline R₀ = 3.5 or 7.0), vaccine rollout speed (slow or fast), and scale of border re-opening (mean of 2500 or 13 000 overseas arrivals per day).

Setting

Simulation population size, age structure, and age-based contact rates based on recent estimates for the Australian population. We assumed that 80% vaccination coverage of people aged 16 years or more was reached in mid-October 2021 (fast rollout) or early January 2022 (slow rollout).
