Researchers at UTHealth Houston have leveraged the Texas All-Payer Claims Database (TX-APCD) to analyze patterns in long COVID diagnoses across various populations and SARS-CoV-2 variant periods from October 2021 to October 2023. This initiative aims to address the existing gap in comprehensive surveillance systems for long COVID, which, unlike acute COVID-19, lacks a dedicated tracking mechanism.

Key findings indicate that older adults, particularly those 70 and older, and Medicare fee-for-service beneficiaries had substantially higher documented rates of long COVID.
