Community Conversations: A Tool in Improving Health Outcomes and Reducing the Burden of Visceral Leishmaniasis (Kala-azar) in Isiolo County, Kenya

Abstract

Visceral Leishmaniasis (Kala-azar) is a neglected tropical disease (NTD) caused by Leishmania species that affects human. Transmission is through the bite of Phlebotomus sandflies. Globally, WHO ranks Kala-azar as the second largest parasitic killer after Malaria. The disease poses a threat to more than a billion people on almost every continent. Approximately 90% of Kala-azar global burden is found in Africa. Major endemicity is documented in Eastern Africa (Kenya, South Sudan, Sudan, Ethiopia, and Somalia). Accurate burden of the disease in Kenya is unknown attributable to inadequate information on disease prevalence, diagnostic challenges, and spatial distribution. Additionally, morbidity and mortality levels from the disease in the Country are unknown ascribable to a low index of suspicion by healthcare workers, diagnostic challenges, and case management. An example of diagnostic challenges is a reported outbreak of ‘unknown disease’ akin to Kala-azar in Marsabit County in May 2023 where nine people were confirmed dead and over 80 hospitalized. This study aimed to analyze community’s prioritization of causes of Kalaazar as well as community awareness of disease prevention and control. Quantitative data were collected using Participatory Epidemiology methods in purposively selected study villages. Qualitative data were collected through semi-structured interviews. Study findings indicated that 97.2% of respondents had heard about Kala-azar. Despite the awareness, a broad gap between knowledge and practice of prevention and control strategies of the disease was evident. Kala-azar was associated with human behaviour like preferences for traditional and alternative treatment approaches (45.2%), evening outdoor practices before going to bed (99.6%), sleeping outdoors (60.1%), occasional bed nets use (69.2%), and availability of domestic animals and wild animals within house yards (54.6%). Cultural beliefs and practices were noted to play a key role in augmenting the disease burden, where most cases had burn scars from traditional healers’ therapeutic burns. As a consequence, they sought medical help after onset of complications, which ranged from increased severity to fatalities. Community engagement was minimal in prevention and control. In this participatory research, we propose behaviour change communication activities for the elimination of Kala-azar as a public health problem. This article serves as a base for future studies aimed at giving voice to communities while enhancing their understanding of causes of diseases, the possibility of enhanced early diagnostic techniques, and options for prevention, control, and surveillance which in turn is translated to action.
