背景情况:
- 疟疾是导致死亡的主要原因,特别是在撒哈拉以南非洲.
- 预测模型对于疟疾控制至关重要,但传统的统计方法存在局限性.
- 经验动态建模 (EDM) 为研究因果关系提供了一种新的方法.
研究的目的:
- 使用EDM调查气候因素,干预覆盖范围和疟疾发病率之间的因果关系.
- 开发短期疟疾预测模型.
- 为了确定疟疾的主要驱动因素的最佳范围和滞后.
主要方法:
- 融合交叉绘图 (CCM) 用于分析肯尼亚西部每月的疟疾数据 (2008-2022年).
- 气候变量 (温度,降雨量,湿度,风速,太阳辐射) 和干预数据 (床网使用) 被纳入.

01:18Steps in Outbreak Investigation
108
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
