This study aimed to clarify the short-term symptoms, duration, and influencing factors in people recovering from coronavirus disease 2019 (COVID-19) after China's dynamic zero-COVID-19 policy was implemented in December 2022.
We included data from a large-scale on-line survey conducted in China between January 14 and February 1, 2023. Participants were individuals of all ages. Chi-squared tests and multivariate logistic regression analyses were performed to identify factors associated with different symptoms.
Overall, 21,012 patients from seven regions of China were included in this study (female: 71.22%). For most patients, the period from symptom onset to a negative nucleic acid test result was ≤10 days (72.33%). The distribution of symptoms varied at different times, with respiratory (1-4 weeks) and psychocardiology (5-8 weeks) symptoms being the most common. Multivariate analysis identified male sex, no comorbidity, and living in northeast and northwest China (compared with central China) as independent factors associated with a lower risk of symptoms, while age (41-60 years) was a possible risk factor (compared with 18-40 years).
Short-term respiratory and psychocardiology symptoms were the most common after COVID-19 recovery. Sex, age, geographical region, and comorbidities were potential influencing factors for the development of short-term symptoms.
