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.

Expert Insight

Q&A: High-Quality Data Lost Amid Noise of Fragmented Media

Politicians remain divided on how to handle the COVID-19 pandemic despite an abundance of high-quality data and analysis indicating the effectiveness of mitigation efforts such as masking. Dr. Filipe Campante attributes this to a decrease in trust in U.S. institutions and siloed social networks fueled by a plethora of biased media outlets and politicians spewing contradictory information.

Pandemic Data Outlook

Collecting Comorbidity Data to Identify COVID-19 Correlations

Little data on comorbidities is currently reported publicly. Comorbidity data is critical to better design treatments, craft health policy and response strategies, and aid in patient care for those infected by SARS-CoV-2. If they aren’t already, States should begin producing, using and sharing this data.
