Universal coverage with insecticide-treated nets (ITNs) is important for malaria control and elimination. The emergence and intensification of insecticide resistance threatens progress made through the deployment of these interventions and has required the development of newer, more expensive ITN types. Understanding malaria prevention behaviour, including barriers and facilitators to net access and use, can support effective decision-making for the promotion and distribution of ITNs.
In-depth interviews and focus group discussions were conducted in 3 to 4 villages per district, in 13 districts across Burkina Faso, Mozambique, Nigeria and Rwanda from 2019 to 2022. Interviews were conducted in the local language, translated and transcribed in English, French or Portuguese. Transcripts were coded and analysed using Nvivo and ATLAS.ti.
ITNs were obtained from mass distribution campaigns, antenatal care and immunization visits, and purchased on the private market in some locations. While there were divergent perspectives in whether the number of distributed nets were adequate, participants consistently expressed concerns of bias, discrimination, and a lack of transparency with the distribution process. ITNs were frequently used alongside other malaria prevention methods. The primary motivation for use was malaria prevention. While some participants reported using nets nightly throughout the year, other participants reported seasonal use, both due to the perceived higher density of mosquitoes and discomfort of sleeping under a net in the increased heat. Other barriers to consistent net use included activities that take place away from the home, sleeping patterns and arrangements, and sensitivity to the insecticides on the nets.
ITNs remain an important malaria control intervention. To ensure adequate and increased net access, distribution campaigns should consider family structures, available sleeping spaces, and other bed sharing preferences when identifying the number of nets needed for distribution. In addition, campaigns should allow for multiple options for net distribution points and timing to accommodate households remote to health services. Continuous distribution channels and complimentary distribution through the private sector could help fill gaps in coverage. Solutions are needed for outdoor malaria transmission, including alternative designs for ITNs, and improving access to complementary personal protective measures.
普及经杀虫剂处理的蚊帐(ITN)对疟疾控制和消除至关重要。杀虫剂耐药性的出现和加剧威胁到通过部署这些干预措施取得的进展,并要求开发更新、更昂贵的 ITN 类型。了解疟疾预防行为,包括获得和使用蚊帐的障碍和促进因素,可以为推广和分发 ITN 提供有效的决策支持。
2019 年至 2022 年期间,在布基纳法索、莫桑比克、尼日利亚和卢旺达的 13 个区,每个区进行了 3 到 4 个村庄的深入访谈和焦点小组讨论。访谈以当地语言进行,然后翻译成英语、法语或葡萄牙语,并进行转录。使用 Nvivo 和 ATLAS.ti 对转录本进行编码和分析。
ITN 是通过大规模分发运动、产前护理和免疫接种访问获得的,在一些地方也可以在私人市场购买。尽管对于分发的蚊帐数量是否足够存在不同看法,但参与者一致表示对分配过程中的偏见、歧视和缺乏透明度表示关注。ITN 经常与其他疟疾预防方法一起使用。使用的主要动机是预防疟疾。虽然一些参与者报告说全年每晚都使用蚊帐,但其他参与者则报告说季节性使用,这既是因为蚊子密度较高,也是因为在炎热天气下睡在蚊帐中感到不适。导致无法持续使用蚊帐的其他障碍包括离家的活动、睡眠模式和安排,以及对蚊帐上杀虫剂的敏感性。
ITN 仍然是一种重要的疟疾控制干预措施。为了确保有足够数量的蚊帐并增加其可及性,分发运动应在确定分发所需的蚊帐数量时考虑家庭结构、可用的睡眠空间和其他共眠偏好。此外,运动应允许有多种分发点和时间的选择,以适应远离卫生服务的家庭。持续的分发渠道和通过私营部门补充分发可以帮助填补覆盖范围的空白。需要解决户外疟疾传播问题,包括 ITN 的替代设计,并改善获得补充个人防护措施的途径。
