Objective:

To explore the variation in the risk of post-COVID symptoms in 2020, comparing the first and second waves of COVID-19 in France, and to identify associated sociodemographic and health-related risk factors.

Key Findings:
  • The risk of post-COVID symptoms was 14.6% during the first wave (March-May 2020) compared to 7.0% during the second wave (September-November 2020).
  • Adjusted relative risk for post-COVID symptoms was 1.36, indicating a significantly higher risk during the first wave.
  • Higher risk was associated with baseline physical conditions and increased acute symptoms; during the first wave, women and individuals with baseline mental conditions also showed increased risk.
Interpretation:

The findings suggest that the risk of developing post-COVID symptoms was significantly higher during the first wave of the pandemic, likely due to heightened anxiety and limited healthcare access at that time.

Limitations:
  • The study may not fully account for all confounding factors influencing post-COVID symptoms.
  • Data collection was limited to specific time frames and may not reflect long-term trends.
Conclusion:

The risk of six-month post-COVID symptoms was notably higher during the first wave of the pandemic in France, highlighting the impact of the pandemic context on health outcomes.
