摘要互联网时代为流行病学研究带来双重影响，既拓展了公共卫生监测的广度与深度，通过海量医学信息资源丰富了疫情预警、疾病预防及健康促进的策略制定，又引发了信息疫情（即信息流行病），错误或虚假信息快速传播，干扰公众认知，削弱公共卫生响应效能，为突发公共卫生事件应对增添复杂性。本文聚焦于信息流行病学的代表性研究领域，如信息病毒引发的信息流行病，并展望其未来发展趋势与潜在挑战，旨在促进信息流行病学研究的深化与公共卫生实践的优化。

abstractsThe internet era has brought a dual impact on epidemiological research: on one hand, it has expanded the breadth and depth of public health surveillance, enriching the formulation of strategies for early warning for public health emergencies and infectious disease outbreaks, disease prevention, and health promotion through vast medical information resources. On the other hand, it has triggered the issue of "infodemic", wherein the rapid spread of misinformation disrupts public perception, weakens the effectiveness of public health responses, and adds complexity to the management of public health emergencies. This paper focuses on representative research areas of infodemiology, for example, infodemic caused by inforus, and explores its future development trends and potential challenges with the aim to deepen infodemiology research and optimize public health practice.
