摘要: This study aimed to investigate the serological characteristics of Ebola virus (EBOV) infection during late phase outbreak in Sierra Leone. In total, 877 blood samples from 694 suspected disease (EVD) cases assessed March December 2015, were analyzed via real-time reverse transcription polymerase chain reaction (RT-PCR) for viral RNA and enzyme-linked immunosorbent assay (ELISA) Luminex detect antibodies against EBOV. Viral load EBOV-specific IgM/IgG titers displayed a declining trend 2015. decreased rapidly at earlier stages after onset, while IgM IgG still persisted 58.1% (18/31) 93.5% (29/31) confirmed EVD patients 3.8% (25/663) 17.8% (118/663) RNA-negative later phase, respectively. Dynamic analysis longitudinally collected eight revealed typically reversed trends increasing and/or response EBOV infection. The present results indicate that certain populations Leone developed immunity an outbreak, providing novel insights into risk assessment infections among human populations.
