Abstract: 

This study aimed to describe the status of post-COVID-19 symptoms and their impact on the quality of life in Vietnamese people.

The secondary analysis was performed on the data from a cross-sectional study conducted in Vietnam in 2022.

Of the 972 participants, 76.75 % reported experiencing at least one COVID-19 symptom. Respiratory and heart symptoms and neurological symptoms were the types of symptoms that were reported the most. An increase in post-COVID-19 symptoms has an association with an increased number of problems in life quality. Pain/discomfort and anxiety/depression were the most common problems regarding the quality of life (35 % and 24.5 %, respectively). Problems with quality of life were significantly associated with all listed post-COVID-19 symptoms, in which depression and anxiety showed the highest impact.

The high prevalence of post-COVID-19 symptoms and their impact on quality of life suggests that the effects of COVID-19 can persist after initial recovery, even in the long term.
