Malaria connectivity describes the flow of parasites among transmission sources and sinks within a given landscape. Because of the spatial and temporal scales at which parasites are transported by their hosts, malaria sub-populations are largely defined by mosquito movement and malaria connectivity among them is largely driven by human movement. Characterising malaria connectivity thus requires characterising human travel between areas with differing levels of exposure to malaria. Whilst understanding malaria connectivity is fundamental for optimising interventions, particularly in areas seeking or sustaining elimination, there is a dearth of human movement data required to achieve this goal. Malaria indicator surveys (MIS) are a generally under utilised but potentially rich source of travel data that provide a unique opportunity to study simple associations between malaria infection and human travel in large population samples. This paper shares the experience working with MIS data from Bioko Island that revealed programmatically useful information regarding malaria importation through human travel. Simple additions to MIS questionnaires greatly augmented the level of detail of the travel data, which can be used to characterise human travel patterns and malaria connectivity to assist targeting interventions. It is argued that MIS potentially represent very important and timely sources of travel data that need to be further exploited.

使用疟疾指标调查数据表征疟疾连通性。

疟疾的连通性描述了特定景观内传播源和汇之间的寄生虫流动。由于寄生虫被其宿主运输的时空尺度,疟疾亚群在很大程度上由蚊子的活动来定义,而它们之间的疟疾连通性在很大程度上是由人类的运动驱动的。因此,表征疟疾的连通性需要表征疟疾暴露水平不同的地区之间的人类旅行。尽管了解疟疾的连通性是优化干预措施的基础,特别是在寻求或维持消灭疟疾的地区,但实现这一目标所需的人体运动数据不足。疟疾指标调查(MIS)是一种通常未被充分利用但潜在丰富的旅行数据来源,可提供独特的机会来研究大量人群样本中疟疾感染与人类旅行之间的简单关联。本文分享了使用比奥科岛(Bioko Island)MIS数据进行工作的经验,这些数据揭示了有关通过人类旅行进口疟疾的程序上有用的信息。对MIS问卷的简单补充极大地提高了旅行数据的详细程度,可用于表征人类旅行模式和疟疾连通性,以帮助进行针对性干预。有人认为,MIS有可能代表非常重要和及时的旅行数据来源,需要进一步利用。本文分享了使用比可科岛(Bioko Island)MIS数据进行工作的经验,这些数据揭示了有关通过人类旅行进口疟疾的程序上有用的信息。对MIS问卷的简单补充极大地提高了旅行数据的详细程度,可用于表征人类旅行模式和疟疾的连通性,以帮助进行针对性干预。有人认为,MIS有可能代表非常重要和及时的旅行数据来源,需要进一步利用。本文分享了使用比奥科岛(Bioko Island)MIS数据进行工作的经验,这些数据揭示了有关通过人类旅行进口疟疾的程序上有用的信息。对MIS问卷的简单补充极大地提高了旅行数据的详细程度,可用于表征人类旅行模式和疟疾的连通性,以帮助进行针对性干预。有人认为,MIS有可能代表非常重要和及时的旅行数据来源,需要进一步利用。可以用来表征人类的出行方式和疟疾的连通性,以帮助有针对性的干预措施。有人认为,MIS有可能代表非常重要和及时的旅行数据来源,需要进一步利用。可以用来表征人类的出行方式和疟疾的连通性,以帮助有针对性的干预措施。有人认为,MIS有可能代表非常重要和及时的旅行数据来源,需要进一步利用。
