After a longstanding global presence, malaria is now largely non-existent or suppressed in most parts of the world. Today, cases and deaths are primarily concentrated in sub-Saharan Africa. According to many experts, this persistence on the African continent reflects factors such as resistance to insecticides and drugs as well as insufficient access to essential commodities such as insecticide-treated nets and effective drugs. Crucially, however, this narrative ignores many central weaknesses in the fight against malaria and instead reinforces a narrow, commodity-driven vision of disease control. This paper therefore describes the core challenges hindering malaria programs in Africa and highlights key opportunities to rethink current strategies for sustainable control and elimination. The epidemiology of malaria in Africa presents far greater challenges than elsewhere and requires context-specific initiatives tailored to national and sub-national targets. To sustain progress, African countries must systematically address key weaknesses in its health systems, improve the quality and use of data for surveillance-responses, improve both technical and leadership competencies for malaria control, and gradually reduce overreliance on commodities while expanding multisectoral initiatives such as improved housing and environmental sanitation. They must also leverage increased funding from both domestic and international sources, and support pivotal research and development efforts locally. Effective vaccines and drugs, or other potentially transformative technologies such as genedrive modified mosquitoes, could further accelerate malaria control by complementing current tools. However, our underlying strategies remain insufficient and must be expanded to include more holistic and context-specific approaches critical to achieve and sustain effective malaria control.
在全球长期存在之后,疟疾如今在世界大部分地区已基本不存在或得到了抑制。如今,病例和死亡主要集中在撒哈拉以南非洲地区。许多专家认为,这种在非洲大陆持续存在的情况反映了诸如对杀虫剂和药物的抗药性以及获得经杀虫剂处理的蚊帐和有效药物等基本商品的机会不足等因素。然而,至关重要的是,这种说法忽略了抗击疟疾斗争中的许多核心弱点,反而强化了一种狭隘的、以商品为驱动的疾病控制观念。因此,本文描述了阻碍非洲疟疾防治项目的核心挑战,并强调了重新思考当前可持续控制和消除战略的关键机遇。非洲的疟疾流行病学面临着比其他地区大得多的挑战,需要针对国家和次国家目标制定因地制宜的举措。为了保持进展,非洲国家必须系统地解决其卫生系统中的关键弱点,提高用于监测应对的数据的质量和使用效率,提升疟疾控制方面的技术和领导能力,逐步减少对商品的过度依赖,同时扩大多部门举措,如改善住房和环境卫生。它们还必须利用来自国内和国际的更多资金,并支持当地关键的研发工作。有效的疫苗和药物,或其他潜在的变革性技术,如基因驱动改造蚊子,可通过补充现有工具进一步加速疟疾控制。然而,我们的基本战略仍然不足,必须加以扩展,纳入对实现和维持有效的疟疾控制至关重要的更全面、因地制宜的方法。
