Chad is a country within the Lake Chad sub region, currently at risk for poliovirus infection. The Lake Chad Task Team on polio eradication in this sub region made significant efforts to reduce the risk of polio transmission in Chad by tacking immunization teams in the Island Settlement using a Geographic Information System (GIS) technology. This article demonstrates the application of GIS technology to track vaccination teams to monitor immunization coverage in the Island settlements, reduce the number of missed settlements, to provide evidence for vaccination implementation and accountability and improve team performance.
In each district where tracking was conducted, global positioning system-enabled Android phones were given to each team on a daily basis and were used to record team tracks. These tracks were uploaded to a dashboard to show the level of coverage and identify areas missed by the teams.
In 2018, tracking covered 30 immunization days, in six rounds. Approximately average of 1173 Island settlements were tracked and covered in each of the six rounds. A total of 806,999 persons aged 0-10 years were immunized, out of which 4273 were zero dose cases at the point of their immunization. Tracking activities were conducted. There was an improvement in the geographic coverage of settlements and an overall reduction in the number of missed settlements.
The tracking of vaccination teams and Island settlements ensured useful information for planning and implementation of polio campaigns and enabled supervisors to evaluate performance of vaccination teams.
乍得是乍得湖次区域内的一个国家,目前面临脊髓灰质炎病毒感染风险。乍得湖次区域根除脊髓灰质炎任务组做出了重大努力,通过使用地理信息系统(GIS)技术在岛屿定居点安排免疫团队,以降低乍得脊髓灰质炎传播风险。本文展示了GIS技术在追踪疫苗接种团队以监测岛屿定居点免疫覆盖率、减少遗漏定居点数量、为疫苗接种实施和问责提供证据以及提高团队绩效方面的应用。
在每个进行追踪的地区,每天为每个团队配备支持全球定位系统的安卓手机,用于记录团队行程轨迹。这些轨迹被上传到一个仪表板,以显示覆盖水平并识别团队遗漏的区域。
2018年,追踪覆盖了6轮共30个免疫日。在这六轮中,每轮大约平均追踪并覆盖了1173个岛屿定居点。共有806,999名0至10岁的人员接受了免疫接种,其中4273人在免疫接种时为零剂次病例。开展了追踪活动。定居点的地理覆盖范围有所改善,遗漏定居点的数量总体减少。
对疫苗接种团队和岛屿定居点的追踪确保了为脊髓灰质炎疫苗接种活动的规划和实施提供有用信息,并使监督人员能够评估疫苗接种团队的绩效。
