**5. Conclusions**

This study has shown that physical and mental fatigue, dizziness, balance impairments, reduced aerobic capacity, poor work ability and low life satisfaction are commonly perceived consequences of post-COVID-19. Work ability, aerobic capacity and fatigue are factors associated with low life satisfaction. The results of this study can serve as guidance for healthcare authorities regarding important long-term consequences that should be considered in rehabilitation programs directed toward post-COVID-19. Future studies should focus on how post-COVID-19 consequences change over time and evaluate the efficacy of rehabilitation protocols for persons with post-COVID-19.
