  • The economic burden of visceral leishmaniasis and barriers to accessing healthcare in Tigray, North Ethiopia: A field based study
    Shewaye Belay Tessema, Tadyos Hagos, Genet Kehasy, Lucy Paintain, Cherinet Adera, et al.
    Plos Neglected Tropical Diseases, 2024
    Background Visceral leishmaniasis (VL) is an important public health problem, which mainly affects the poor rural dwelling communities in Low- and Middle-Income Countries. However, little is known about the health and economic burdens of this disease in East Africa, including Ethiopia. The aim of this study was to assess the household level economic burden of VL among affected communities in Tigray, Northern Ethiopia. Methods Between April and August 2020, a cross-sectional household survey was conducted on 96 patients who had been treated for VL within 12 months prior to the survey, in six districts of Tigray. Data on households’ health seeking behavior, direct and indirect costs and coping strategies were collected using a structured questionnaire and the responses were analyzed using SPSS software. Results Most (82%) of the patients surveyed were males and the majority (74%) of them were between 16 and 30 years of age. The education level of participants was very low: over 33% had not received any form of education; 48% of patients were farmers dependent on subsistence agriculture and about 32% were daily laborers. Just under half of household families (46%) resided in “poor houses” with structures made from entirely local materials. Forty-one percent of patients from the surveyed households had traveled 48 to 72 kilometers to reach VL treatment hospitals. The median total household cost for one VL episode was estimated to be US$ 214. This is equated to 18% of the mean total annual household income or 72.5% of annual per capita income of the study population. More than 80% of the households surveyed incurred catastrophic costs of VL, where this is defined as exceeding 10% of annual household income. The median delay between the onset of symptoms and arrival at a care provider hospital was 37 days; once the patient arrived at hospital, the median delay during diagnosis was 3 days. Direct and indirect costs represented 44% and 56% of the total costs incurred, respectively. To cope with VL treatment costs, 43% of the households used more than one coping strategy: 48% took out loans, 43% sold livestock and 31% of households mobilized cash savings. Conclusions VL in Tigray is concentrated among young males with low educational background and mostly engaged in subsistence economic activities. Despite the free diagnostic and treatment provisions that were available at public hospitals at the time of the study, our work shows that the household economic burden of the disease had significant impact among VL-affected communities in Tigray. Initiating community awareness towards prevention, early treatment seeking and decentralization of VL treatment centers are strongly recommended. In addition, we recommend efforts to reduce household treatment costs through transport and food provisions for patients (and their accompanying carers where possible) or through cash reimbursement for patients who complete treatment at public hospitals, in order to reduce the barriers to seeking treatment for this life-threatening disease.
  • Understanding the risk perception of visceral leishmaniasis exposure and the acceptability of sandfly protection measures among migrant workers in the lowlands of Northwest Ethiopia: a health belief model perspective
    Resom Berhe, Mark Spigt, Francine Schneider, Lucy Paintain, Cherinet Adera, et al.
    BMC Public Health, 2022
    Background Visceral leishmaniasis (VL) is the leading cause of health concerns among Ethiopian migrant workers. Understanding risk perception and health-protective behavior are significant challenges in the prevention and eradication of the disease. As a result, studies are required to assess these important epidemiological factors, which will provide guidance on how to assist migrant workers in taking preventive measures against VL. Method We conducted qualitative research among migrant workers on seasonal agricultural farms in Northwest Ethiopia between June and November 2019 to assess their perception of the risk of contracting VL and their willingness to use protective measures against the disease. Seventeen focus group discussions and 16 key informant interviews were conducted to study migrant workers’ risk perception in relation to sandfly bite exposure and use of sandfly control measures. For analysis, all interviews were recorded, transcribed, and translated. ATLASti was used to perform qualitative content analysis on the data. Result Migrant workers are fearful of VL because of previous exposure and the disease’s prevalence in the area. They believe, however, that VL is a minor illness that is easily treated. While Insecticide Treated Nets (ITNs) are widely accepted as a protective measure, there are still reservations about using them due to the seasonality of the transmission, difficulties in hanging them on farm areas, and a preference for alternative traditional practices. Regardless of perceived self-efficacy, the central cues were the message delivered by the health workers and an increase in sandfly bite irritation. Based on the findings, three levels of intervention modalities are suggested: 1) increasing pre-arrival awareness through outdoor media (posters, stickers, billboards), 2) encouraging proper use of protective measures upon arrival at farm camps, and 3) informing departing workers on disease recognition and best practices for health-seeking continuous use of protective measures at home. Conclusion This finding suggests that VL prevention interventions should focus on individuals’ perceptions in order to promote consistent use of protective measures. The findings are highly useful in planning effective interventions against VL.
  • Moving from control to elimination of Visceral Leishmaniasis in East Africa
    Louise Kathini Makau-Barasa, Duncan Ochol, Kelly A. Yotebieng, Cherinet B. Adera, Dziedzom K. de Souza
    Frontiers in Tropical Diseases, 2022
    Visceral leishmaniasis (VL) is arguably one of the deadliest neglected tropical diseases. People in poverty bear the largest burden of the disease. Today, the largest proportion of persons living with VL reside in the Eastern African countries of Ethiopia, Kenya, Somalia, South Sudan, and Sudan. These East African countries are among the top 10 countries reporting the highest number of cases and deaths. If left undiagnosed and untreated, VL almost always results in death. Subsequently, there is a need for integrated efforts across human, animal, and vector-control programs to address the scourge of VL in East Africa. In the East African region, the challenges including socio-cultural beliefs, poor health system, political instability, and limited epidemiological understanding impede the implementation of effective VL control strategies. The availability of funding, as well as diagnostics and treatment options, are also devastatingly limited. Furthermore, given the realities of climate change and population movement in the region, to effectively address the scourge of visceral leishmaniasis in East Africa, a regional approach is imperative. In this paper, we highlight some of the key challenges and opportunities to effectively move towards an effective control, and eventually elimination, of VL in East Africa. To do this, we underline the need for a fully integrated program in East Africa, inclusive of effective diagnostics and treatment, to effectively reduce and eliminate the burden of VL in the region, subsequently paving the way to achieve global elimination goals.

    Journal of Infection in Developing Countries, 2020
    Introduction: In three health care facilities in the Oromia region, the aim of this study is to report on 1) the number of VL cases registered over time (2013-2018) and 2) the clinical profile, type of treatment used and response to treatment.
 Methodology: A retrospective cohort study was conducted among all VL cases admitted with a diagnosis of VL.
 Results: A total of 434 VL cases were registered at the three health facilities, but patient files were available for only 188. Most (51.6%) were children and only three presented with VL relapse. 78 (41.5%) of the 188 patients presented within one month of symptom onset. Concurrent severe acute malnutrition (27.1%), tuberculosis (6.4%) and malaria (6.4%) were common. There were only two cases with HIV coinfection. Fourty-three percent were treated with antimonials, 34% with antimonials combined with paromomycin and 23% with AmBisome. Amongst the 188 patients with patient files there were no deaths and one treatment failure. Six months outcome data were however missing for all. Aggregated data from the 434 VL cases reported three deaths, two treatment failures and one relapse.
 Conclusions: Children were most commonly affected, suggesting long-term endemicity. While short-term outcomes are encouraging, long-term follow-up data are required.
