The Polaris Observatory is developed and managed by the CDA Foundation, a non-profit organization. The goal of the Polaris Observatory is to provide data, tools, training and decision analytics to support elimination of hepatitis B and C globally by 2030. The activities of the observatory are overseen by an independent advisory board with representatives from global health organizations, academia, liver societies, civil societies and donors.

We work with stakeholders in countries to assess the present and future disease burden and strategies that can achieve country defined targets. The observatory also develops national estimates based on published data when we can’t identify country level experts (highlighted in the Dashboard page).

In addition, we develop global estimates based on approved, estimate and extrapolated data. Extrapolated data applies to countries where there is simply no published data available. Extrapolation from neighboring countries is used to develop an estimate.

Our guiding principles are as follow:

• Function as a platform to provide data, tools and analyses with a user friendly interface
• Facilitate good decisions and policies through quality data and analyses
• Develop partnerships at country and regional levels to collect and analyze hepatitis data
• Validate all data/analyses with local experts
• Complement country interviews with literature searches to minimize the burden on country experts
• Publish key findings with local collaborators

The following tools and services are offered to all countries interested in collaborating:

• HCV disease burden modeling
• HCV economic impact modeling
• HBV vertical transmission (vaccination/treatment), horizontal transmission and disease burden modeling
• HBV economic impact modeling
