Follow-up for discharged patients
After discharged patients completed 14 days of quarantine, it is recommended for these patients to be followed up in their communities for at least 28 days. GZCDC follows the health management plan for discharged COVID-19 patients released by the National Health Commission of China(National_Health_Commission_of_China, 2020), and RT-PCR testing was performed on the 14th and 28th days after quarantine or more frequently. During the follow-up period, if a person tested positive by RT-PCR, he or she should go to the hospital for a comprehensive evaluation as soon as possible, and treatment should be conducted according to the latest national clinical guidance. If a person tested negative by RT-PCR but CT images showed abnormalities or symptoms occurred, symptomatic treatment could be given according to the related disease(s).
