Challenges and strategies for the uptake of mass drug administration among pastoralist communities in South Sudan

Abstract

Preventive chemotherapy through mass drug administration (MDA) to control and eliminate neglected tropical diseases (NTDs) requires the active participation of communities living with NTDs, or at risk of NTD infections. Despite considerable progress by national control and elimination programs, achieving consistent and sustainable treatment campaigns that reach pastoralist communities remains challenging, which in turn delays the achievement of global disease elimination goals. The challenges of accessing pastoralist communities for treatment also hinder the achievement of the UN’s Sustainable Development Goals’ (SDGs) pledge to “leave no one behind“. Elimination targets cannot be achieved if significant proportions of endemic populations, such as pastoralists, are missed out during treatment campaigns. In South Sudan, close to 70% of the population is categorized as pastoralist, with previous data on MDA showing low access to and acceptance of MDA among the pastoralist community, as well as inconsistent treatment coverage. To address this challenge, a cross-sectional study design was conducted in five counties, with 239 pastoralist community respondents participating in in-depth interviews (IDIs), key informant interviews (KIIs), and focus group discussions (FGDs). Our findings show that, in the pastoralist community, high mobility, lay perceptions about the causes of NTDs and methods of treating them, limited awareness of MDA, and suboptimal health-seeking behaviors are the major factors that limit accessibility and participation. Our results suggest that improved uptake of MDA in these communities may be achieved by timing treatment campaigns to take account of pastoralists’ seasonal migration patterns, by involving pastoralist leaders in planning and social mobilization activities, by engaging community members as community drug distributors (CDDs), by using participatory behavior change approaches to design NTD interventions, and by addressing negative perceptions around the medicines involved, including those related to drug expiry and drugs causing impotence or other side effects. The results from this study could enable national programs to address the challenges of implementing treatment campaigns through the enhanced involvement and representation of pastoralist communities.

Impact of annual community-directed treatment with ivermectin on the incidence of epilepsy in Mvolo, a two-year prospective study

“…Understanding and addressing the underlying reasons for the low ivermectin uptake is therefore vital. Strategies could include reducing ivermectin misconceptions [ 62 ], raising OAE awareness [ 47 ] and adapting CDTI strategies to local contexts, such as considering seasonal farming migrations [ 63 ]. This should be a priority not only for Mvolo County but also across the onchocerciasis-endemic regions of South Sudan, given that all states in the country are endemic [ 64 ] and have reported less than five rounds of optimal annual CDTI [ 24 ].…”

Impact of War on the Drug Supply for Cancer Patients in Sudan

“…The country's healthcare system, already burdened by limited resources and infrastructure challenges, has struggled to meet the escalating demands imposed by rising cancer incidence rates. The prevalence of cancers, spanning from breast and cervical cancers to lymphomas and leukaemias, has surged, creating an urgent need for comprehensive and accessible treatment options (Muchiri et al, 2023). The ongoing conflicts have significantly hampered the healthcare infrastructure, exacerbating the already challenging circumstances faced by cancer patients.…”
