A new, comprehensive framework has been launched to guide health authorities, policy makers and other stakeholders towards elimination of visceral leishmaniasis as a public health problem in Eastern Africa.
Also known as kala-azar, visceral leishmaniasis is a deadly parasitic disease that causes fever, weight loss, spleen and liver enlargement, and —if untreated — death. Transmitted by the bite of infected female sandflies, visceral leishmaniasis is endemic in 80 countries around the world. In 2022, Eastern Africa accounted for 73% of global visceral leishmaniasis cases, half of which occurred in children under 15.
The elimination framework outlines five main strategies for guiding visceral leishmaniasis elimination: early diagnosis and treatment; integrated vector management; effective surveillance; advocacy, social mobilization, building partnerships; and implementation and operational research. It also includes a step-by-step process for implementing the main elimination phases and sets country and regional targets, such as a 90% reduction in visceral leishmaniasis burden in the Eastern Africa sub-region to fewer than 1,500 per year by 2030; detection and treatment of 90% of cases within 30 days of onset of symptoms by 2030; a 100% decline in visceral leishmaniasis deaths in children by 2030; 100% of visceral leishmaniasis-HIV patients started on ART therapy; and the detection, reporting, and management of all post-kala-azar dermal leishmaniasis (PKDL) cases.
‘The introduction of this new framework represents a significant step forward in our collective efforts to eliminate visceral leishmaniasis from Eastern Africa,’ said Dr Saurabh Jain, Scientist and WHO Focal Point for Visceral Leishmaniasis. ‘By providing countries with tailored tools and strategies, we are laying a strong foundation for sustained progress in the fight against this neglected disease.’
The framework developed by the World Health Organization (WHO) in collaboration with various partners, including the non-profit drug research and development organization Drugs for Neglected Diseases initiative (DNDi) and Ministries of Health across the region, was launched at a meeting co-hosted by WHO, DNDi, and the Ministry of Health in Ethiopia. The meeting was attended by officials from the ministries of health of nine high visceral leishmaniasis burden countries in Africa, namely Chad, Djibouti, Eritrea, Ethiopia, Kenya, Somalia, South Sudan, Sudan, and Uganda, as well as representatives from the African Union, researchers, academia, the private sector, and funding institutions.
‘The visceral leishmaniasis elimination framework will offer important direction to countries in the region and provide momentum to reach the finish line of elimination,’ said Dr Dereje Duguma, State Minister of the Federal Ministry of Health, Ethiopia. ‘The government of Ethiopia remains committed to working with partners to develop programmes at all levels, from national to community, to expand access to healthcare and achieve the targets of elimination by 2030.’
The launch of the Eastern Africa framework comes at a time when countries in Asia are already demonstrating success in eliminating visceral leishmaniasis as a public health problem.
Between 2004 and 2008, Bangladesh, India, and Nepal collectively accounted for 70% of global cases. However, in October last year, the WHO announced that Bangladesh had successfully eliminated visceral leishmaniasis as a public health problem — making it the first country in the world to achieve this status. The elimination process in Asia began in 2005 with the launch of a regional Strategic Framework for Visceral Leishmaniasis. This framework, coupled with an accelerated elimination program, political commitment, and sustained stakeholder support, significantly contributed to achieving elimination goals.
The new framework for Eastern Africa presents a similar opportunity for the nine endemic countries, offering a comprehensive approach for countries to implement strategies, assess progress, identify gaps, and build capacity.
‘Visceral leishmaniasis is a severe disease primarily affecting vulnerable groups, such as children and the poorest populations. I am very pleased that the framework’s core pillars prioritize innovation for these neglected populations. Since its establishment in 2003, DNDi has focused on developing new, safer, more efficacious, and patient-friendly treatments. This, combined with complementary strategies such as vector control, undoubtedly will play a pivotal role in the journey towards elimination’, said Professor Samuel Kariuki, the Eastern Africa Director for DNDi.
Continuous research and development of new tools will be key to overcoming remaining obstacles and sustaining elimination of visceral leishmaniasis. Current tools, though effective, remain challenging due to complex administration and potential toxicity, limiting their use in primary healthcare settings.
The launch of the framework follows the Nairobi Declaration (January 2023), where representatives from the ministries of health of Chad, Eritrea, Ethiopia, Kenya, Somalia, South Sudan, Sudan, and Uganda, along with key stakeholders in the region, committed to eliminating visceral leishmaniasis as a public health problem by 2030.
The framework was developed in consistency with the WHO roadmap for neglected tropical diseases 2021-2030, a 10-year plan formulated to guide all nations working towards the control and elimination of neglected tropical diseases.
About DNDi
The Drugs for Neglected Diseases initiative (DNDi) is a not-for-profit medical research organization that discovers, develops, and delivers safe, effective, and affordable treatments for neglected people. DNDi is developing medicines for sleeping sickness, leishmaniasis, Chagas disease, river blindness, mycetoma, dengue, paediatric HIV, advanced HIV disease, cryptococcal meningitis, and hepatitis C. Its research priorities include children’s health, gender equity and gender-responsive R&D, and diseases impacted by climate change. Since its creation in 2003, DNDi has joined with public and private partners across the globe to deliver 13 new treatments, saving millions of lives.
