Winter Situational Assessment

Predict past, current, and short-term future trends in respiratory virus activity to support public health awareness and response.

Annual Winter Situational Assessment Program

The clinical burden from acute viral respiratory infections during winter months will often be the result of multiple concurrent epidemics. In temperate regions, many countries experienced overlapping epidemics of influenza, RSV and COVID-19, exerting unusual pressure on ICU capacity during winter months. Short-term forecasting of epidemic activity can help to enable rapid understanding of the status of concurrent epidemics and preparation for any increased impact on healthcare services.

The project has the following aims:

  1. To generate real-time epidemic analysis of COVID-19, influenza, and RSV in Australia and New Zealand.

  2. To develop enhanced methods for epidemic situational assessment of viral respiratory pathogens.

  3. To assess forecast utility and public health value through both statistical performance evaluation and engagement with public health partners.
