People who have recovered from Covid -19 may lose their immunity to the disease within months, according to research suggesting the virus could reinfect people year after year, like common colds.
武漢肺炎（新型冠狀病毒病，COVID-19）患者康復後，可能會在數月內失去對該疾病的免疫力；研究顯示，武肺病毒可能會讓人們每年重複被感染，就像普通感冒一樣。
In the first longitudinal study of its kind, scientists analysed the immune response of more than 90 patients and healthcare workers at Guy’s and St Thomas’ NHS foundation trust and found levels of antibodies that can destroy the virus peaked about three weeks after the onset of symptoms then swiftly declined.
在首個同類型縱貫性研究中，科學家分析（英國）「蓋伊和聖托馬斯國民保健信託基金會」的90多名患者和醫護人員的免疫反應，發現可以摧毀病毒的抗體水平，在症狀出現3週後達到高點，然後迅速下降。
Blood tests revealed that while 60% of people marshalled a "potent" antibody response at the height of their battle with the virus, only 17% retained the same potency three months later. Antibody levels fell as much as 23- fold over the period. In some cases, they became undetectable.
血液檢測發現，儘管60%的人在和病毒奮戰時體內產生「強有力的」抗體反應，但只有17%的人在3個月後還有同樣強大的抗體。在此期間抗體水平下降幅度達23倍。在某些情況下，甚至檢測不到抗體。
