新型冠状病毒肺炎长期症状及其科学防控

国内外已有较多研究发现新型冠状病毒(简称新冠病毒)感染者存在长期症状，即COVID-19长期症状(long COVID-19)，也被称为COVID-19后遗症(post-COVID-19 condition)。WHO将COVID-19长期症状定义为新冠病毒感染者在感染病毒3个月后所出现的、持续至少2个月，并且无法被其他诊断所解释的症状。COVID-19长期症状包括全身症状如疲劳、头痛及呼吸困难等，影响精神与神经、呼吸、心血管和消化等多个系统。基于已有研究证据，建议加强COVID-19长期症状的科学研究、现阶段坚持“动态清零”总方针、加快推进疫苗全程接种、未来开展COVID-19长期症状的早期监测与干预，以有效防止COVID-19长期症状带来的远期疾病负担和经济负担。

Long COVID-19 and its scientific prevention and control

Global literature have reported that individuals who have recovered from the acute phase of COVID-19 may suffer from persistent symptoms, namely long COVID-19, also known as the post-COVID-19 condition. WHO defined that long COVID-19 occurs in individuals with a history of SARS-CoV-2 infection, usually 3 months from the onset of COVID-19 with symptoms and that last for at least 2 months and cannot be explained by an alternative diagnosis. Symptoms of long COVID-19 include fatigue, headache dyspnea and so on, affecting multiple systems such as neurological, psychiatric, respiratory, cardiovascular and gastrointestinal systems. Based on the existing evidence, it is suggested to strengthen scientific research on long COVID-19, persist in a "dynamic COVID-zero strategy" currently to reduce infections, accelerate vaccination coverage, and carry out early monitoring and intervention of long COVID-19, to cope with the long-term disease and economic burden caused by long COVID-19.
