安全有效的伤寒结合疫苗 (TCV) 已经存在,但许多国家缺乏优先向最高风险社区引入 TCV 所需的高分辨率数据。在这里,我们讨论血清流行病学——一种使用抗体反应数据来表征感染负担的方法——作为填补这一数据空白的潜在工具。伤寒血清学检测已经存在一百多年了,但直到最近才鉴定出足够敏感和特异的抗原,可以用作流行病学标志物。这些抗原与新方法学的发展相结合,可以通过横断面血清调查来估计血清发生率(人群中新感染发生的比率)。这些新工具为肠热病血清流行病学开辟了许多可能的应用,包括生成高分辨率监测数据、监测疫苗的影响以及与其他血清监测举措相结合。挑战依然存在,包括区分伤寒沙门氏菌和副伤寒沙门氏菌感染以及解释再感染的情况。肠热病血清流行病学的成本、时间和样本量仅为监测血培养研究的一小部分,并且可以对这种重要的传染病进行更有效和可扩展的监测。
Safe and effective typhoid conjugate vaccines (TCVs) are available, but many countries lack the high-resolution data needed to prioritize TCV introduction to the highest-risk communities. Here we discuss seroepidemiology—an approach using antibody response data to characterize infection burden—as a potential tool to fill this data gap. Serologic tests for typhoid have existed for over a hundred years, but only recently were antigens identified that were sensitive and specific enough to use as epidemiologic markers. These antigens, coupled with new methodological developments, permit estimating seroincidence—the rate at which new infections occur in a population—from cross-sectional serosurveys. These new tools open up many possible applications for enteric fever seroepidemiology, including generating high-resolution surveillance data, monitoring vaccine impact, and integrating with other serosurveillance initiatives. Challenges remain, including distinguishing Salmonella Typhi from Salmonella Paratyphi infections and accounting for reinfections. Enteric fever seroepidemiology can be conducted at a fraction of the cost, time, and sample size of surveillance blood culture studies and may enable more efficient and scalable surveillance for this important infectious disease.
