Abstract

Background: We describe the serological response following H1N1-2009 influenza A infections confirmed by reversetranscriptase polymerase chain reaction (RT-PCR). Methodology and Principal Findings: The study included patients admitted to hospital, subjects of a seroepidemiologic cohort study, and participants identified from outbreak studies in Singapore. Baseline (first available blood sample) and follow-up blood samples were analyzed for antibody titers to H1N1-2009 and recently circulating seasonal influenza A virus strains by hemagglutination inhibition (HI) and virus micro-neutralization (VM) assays. 267 samples from 118 cases of H1N1- 2009 were analyzed. Geometric mean titers by HI pea..
