WA Department of Health COVID-19 modelling

The WA Department of Health has undertaken modelling to reflect the recent emergence of the Omicron strain of COVID-19 in our community and how this new variant affects WA’s planning to transition to living with COVID-19.

Important considerations which have impacted the modelling include:

• The very different nature of Omicron which evidence has shown to be substantially less severe than the Delta strain, albeit far more transmissible.
• The levels of immunity within the Western Australian population as a result of high levels of vaccination and the significant booster uptake.
• The trajectory of the current outbreak and how it impacts the risk assessment of opening our borders.
