Article Synopsis
  • - Early in the COVID-19 pandemic, the CDC adapted its existing surveillance system to monitor cases and deaths efficiently, implementing a new aggregate case surveillance system for quicker data collection and emergency response.
  • - This new system enabled the CDC to gather and analyze COVID-19 data at national, state, and county levels, using innovative methods like web scraping and algorithms to streamline data accuracy and validation.
  • - The review emphasizes the importance of having a robust aggregate surveillance system ready for future health emergencies, providing near-real-time data to enhance response efforts beyond traditional individual case reporting.

Article Synopsis
  • - During the COVID-19 pandemic, the CDC implemented an aggregate case and death surveillance (ACS) system to effectively track cumulative COVID-19 data, supplementing traditional reporting methods.
  • - As public health jurisdictions updated their historical data, the CDC developed a manual process for updating the ACS dataset to improve the accuracy of reported case and death numbers.
  • - By March 2022, the CDC began integrating data from three jurisdictions via application programming interfaces (APIs), which streamline data transfer and may enhance emergency response efficiency moving forward.
