Malaria incidence in the Greater Mekong Subregion has been on the decline, and most remaining malaria risk in the region is concentrated among hard-to-reach populations, especially those with exposure to forested areas. New vector control tools focused on outdoor protection in forest settings are needed for these populations.
The delivery of a 'forest pack' containing a volatile pyrethroid spatial repellent (VPSR), a topical repellent, and pyrethroid treatment of clothing was evaluated in an operational study in Cambodia. Costs were collected using micro-costing approaches and the cost of distribution for the 'forest pack' was estimated using standard economic evaluation approaches and examined in sensitivity analyses.
The cost per eligible person (the target population) per malaria season for the whole pack was estimated to be 138 USD, which was nearly entirely driven by the cost of the products.
Modifications to the 'forest pack' including adding a longer-lasting spatial repellent product or a reduced-cost topical repellent could significantly reduce the cost of pack distribution over the course of a malaria season.
大湄公河次区域的疟疾发病率一直在下降,该区域剩余的大多数疟疾风险集中在难以到达的人群中,特别是那些接触森林地区的人群。这些人群需要专注于森林环境户外防护的新型病媒控制工具。
在柬埔寨的一项实地研究中,对包含拟除虫菊酯挥发性空间驱避剂(VPSR)、局部驱避剂和衣物拟除虫菊酯处理的“森林套装”的发放情况进行了评估。使用微观成本核算方法收集成本,并使用标准经济评估方法估算“森林套装”的分发成本,并在敏感性分析中进行检验。
整个套装每个疟疾季节每位符合条件的人(目标人群)的成本估计为138美元,这几乎完全由产品成本驱动。
对“森林套装”进行改进,包括添加更长效的空间驱避产品或成本更低的局部驱避剂,可以在疟疾季节显著降低套装分发成本。
