US Adult Long COVID Trends and Activity Limitation, 2022–2024

National Health Interview Survey data from 2022 to 2024 on long COVID prevalence among US adults. The dataset includes 88,731 participants and provides nationally representative estimates for trends, demographic factors, and associated activity limitations. Analysis was conducted in October 2025 by Xiaoli Jia.

Use Cases

• Modeling long COVID prevalence trends over time based on repeated cross-sectional survey cycles.
• Identifying demographic and socioeconomic risk factors for long COVID based on self-reported participant characteristics.
• Assessing the impact of long COVID on daily activity limitation based on self-reported functional status.

Strengths

• Nationally representative estimates derived from survey-weighted analysis of 88,731 adults.
• Clear temporal coverage across three survey cycles from 2022 to 2024.
• Includes specific prevalence percentages with confidence intervals for both 'ever' and 'current' long COVID.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is based on participant self-report, which may introduce recall or reporting bias.
• Row count is unknown, which may limit suitability assessment.
