Recently, several studies characterizing adaptive immune responses to SARS-CoV-2 infection have reported that most COVID-19 convalescent individuals have detectable neutralizing antibodies, which correlate with the numbers of virus-specific T cells26,27,28,29. In this study, we observed that IgG levels and neutralizing antibodies in a high proportion of individuals who recovered from SARS-CoV-2 infection start to decrease within 2–3 months after infection. In another analysis of the dynamics of neutralizing antibody titers in eight convalescent patients with COVID-19, four patients showed decreased neutralizing antibodies approximately 6–7 weeks after illness onset30. One mathematical model also suggests a short duration of immunity after SARS-CoV-2 infection31.

Of the 37 asymptomatic individuals, three had lymphopenia and one had thrombocytopenia. Six individuals had elevated levels of alanine aminotransferase, and 11 had increased C-reactive protein levels.
Upon admission, chest computed tomography (CT) scans showed focal ground-glass opacities in 11 asymptomatic individuals (11/37, 29.7%) and stripe shadows and/or diffuse consolidation in ten individuals (10/37, 27.0%), whereas 16 individuals (16/37, 43.2%) had no abnormalities (Fig. 1). Five individuals developed focal ground-glass opacities or stripe shadows on chest CT within 5 d of hospital admission. There were no pleural effusions, air bronchogram signs or enlarged lymph nodes, which were typical changes seen in critically symptomatic patients8,9,10. Abnormal radiological findings confined to one lung were identified in 66.7% (14/21) of the asymptomatic individuals, whereas 33.3% (7/21) had abnormalities in both lungs.
