Title: Voluntary Community Human Immunodeficiency Virus Testing, Linkage, and Retention in Care Interventions in Kenya: Modeling the Clinical Impact and Cost-effectiveness Authors: Luong Nguyen, LB; Yazdanpanah, Y; Maman, D; Wanjala, S; Vandenbulcke, A; Price, J; Parker, RA; Hennequin, W; Mendiharat, P; Freedberg, KA Abstract: In southwest Kenya, the prevalence of human immunodeficiency virus (HIV) infection is about 25%. Médecins Sans Frontières has implemented a voluntary community testing (VCT) program, with linkage to care and retention interventions, to achieve the Joint United Nations Program on HIV and AIDS (UNAIDS) 90-90-90 targets by 2017. We assessed the effectiveness and cost-effectiveness of these interventions.

Title: Three parallel information systems for malaria elimination in Swaziland, 2010-2015: are the numbers the same? Authors: Zulu, Z; Kunene, S; Mkhonta, N; Owiti, P; Sikhondze, W; Mhlanga, M; Simelane, Z; Geoffroy, E; Zachariah, R Abstract: Background: To be able to eliminate malaria, accurate, timely reporting and tracking of all confirmed malaria cases is crucial. Swaziland, a country in the process of eliminating malaria, has three parallel health information systems. Design: This was a cross-sectional study using country-wide programme data from 2010 to 2015. Methods: The Malaria Surveillance Database System (MSDS) is a comprehensive malaria database, the Immediate Disease Notification System (IDNS) is meant to provide early warning and trigger case investigations to prevent onward malaria transmission and potential epidemics, and the Health Management Information Systems (HMIS) reports on all morbidity at health facility level. Discrepancies were stratified by health facility level and type. Results: Consistent over-reporting of 9-85% was noticed in the HMIS, principally at the primary health care level (clinic and/or health centre). In the IDNS, the discrepancy went from under-reporting (12%) to over-reporting (32%); this was also seen at the primary care level. At the hospital level, there was under-reporting in both the HMIS and IDNS. Conclusions: There are considerable discrepancies in the numbers of confirmed malaria cases in the HMIS and IDNS in Swaziland. This may misrepresent the malaria burden and delay case investigation, predisposing the population to potential epidemics. There is an urgent need to improve data integrity in order to guide and evaluate efforts toward elimination.
Title: Did microbial larviciding contribute to a reduction in malaria cases in eastern Botswana in 2012-2013? Authors: Obopile, M; Segoea, G; Waniwa, K; Ntebela, DS; Moakofhi, K; Motlaleng, M; Mosweunyane, T; Edwards, JK; Namboze, J; Butt, W; Manzi, M; Takarinda, KC; Owiti, P Abstract: Setting: Larviciding has potential as a component of integrated vector management for the reduction of malaria transmission in Botswana by complementing long-lasting insecticide nets and indoor residual sprays. Objective: To evaluate the susceptibility of local Anopheles to commonly used larvicides. Design: This field test of the efficacy of Bacillus thuringiensis subsp. israliensis vs. Anopheles was performed by measuring larval density before treatment and 24 h and 48 h after treatment in seven sites of Bobirwa district, eastern Botswana, in 2012 and 2013. Vector density and malaria cases were compared between Bobirwa and Ngami (northwestern Botswana), with no larviciding in the control arm. Results: Larviciding reduced larval density by 95% in Bobirwa in 2012, with two cases of malaria, while in 2013 larval density reduction was 81%, with 11 cases. Adult mosquito density was zero for both years in Robelela village (Bobirwa), compared to respectively four and 26 adult mosquitoes per room in Shorobe village (Ngami) in 2012 and 2013. There were no cases of malaria in Robelela in either year, but in Shorobe there were 20 and 70 cases, respectively, in 2012 and 2013. Conclusion: Larviciding can reduce the larval density of mosquitoes and reduce malaria transmission in Botswana. Large-scale, targeted implementation of larviciding in districts at high risk for malaria is recommended.
Title: "Kala-Azar is a Dishonest Disease": Community Perspectives on Access Barriers to Visceral Leishmaniasis (Kala-Azar) Diagnosis and Care in Southern Gadarif, Sudan Authors: Sunyoto, T; Adam, GK; Atia, AM; Hamid, Y; Babiker, RA; Abdelrahman, N; Vander Kelen, C; Ritmeijer, K; Alcoba, G; den Boer, M; Picado, A; Boelaert, M Abstract: Early diagnosis and treatment is the principal strategy to control visceral leishmaniasis (VL), or kala-azar in East Africa. As VL strikes remote rural, sparsely populated areas, kala-azar care might not be accessed optimally or timely. We conducted a qualitative study to explore access barriers in a longstanding kala-azar endemic area in southern Gadarif, Sudan. Former kala-azar patients or caretakers, community leaders, and health-care providers were purposively sampled and thematic data analysis was used. Our study participants revealed the multitude of difficulties faced when seeking care. The disease is well known in the area, yet misconceptions about causes and transmission persist. The care-seeking itineraries were not always straightforward: "shopping around" for treatments are common, partly linked to difficulties in diagnosing kala-azar. Kala-azar is perceived to be "hiding," requiring multiple tests and other diseases must be treated first. Negative perceptions on quality of care in the public hospitals prevail, with the unavailability of drugs or staff as the main concern. Delay to seek care remains predominantly linked to economic constraint: albeit treatment is for free, patients have to pay out of pocket for everything else, pushing families further into poverty. Despite increased efforts to tackle the disease over the years, access to quality kala-azar care in this rural Sudanese context remains problematic. The barriers explored in this study are a compelling reminder of the need to boost efforts to address these barriers.
