Q&A: Data on Behaviors and Beliefs Empowers Countries to Combat COVID-19

Throughout the pandemic, some in the public have acted in opposition to data-driven efforts such as vaccination and masking. The COVID Behaviors Dashboard presents a rich dataset on human behavior and beliefs around the globe that guides governments’ and health departments’ strategies to effectively mitigate COVID-19 in their areas.

Pandemic Data Outlook

Constrained Testing Efforts Require Data on Testing Accessibility

COVID-19 testing data are crucial for the continued pandemic response, but testing utilization and availability began to decrease following vaccine rollout. Data on testing accessibility are necessary to ensure equitable and effective distribution of testing, which will in turn improve the quality of testing data for monitoring COVID-19 transmission.
