An integrated health delivery platform, targeting soil-transmitted helminths (STH) and canine mediated human rabies, results in cost savings and increased breadth of treatment for STH in remote communities in Tanzania

Abstract

BackgroundAchieving the Sustainable Development Goal of a 90% reduction in neglected tropical diseases (NTDs) by 2030 requires innovative control strategies.This proof-of-concept study examined the effectiveness of integrating control programs for two NTDs: mass drug administration (MDA) for soil-transmitted helminths in humans and mass dog rabies vaccination (MDRV).MethodsThe study was carried out in 24 Tanzanian villages. The primary goal was to demonstrate the feasibility of integrating community-wide MDA for STH and MDRV for rabies. The objectives were to investigate the popularity, participation and cost and time savings of integrated delivery, and to investigate the reach of the MDA with respect to primary school-aged children and other community members. To implement, we randomly allocated villages for delivery of MDA and MDRV (Arm A), MDA only (Arm B) or MDRV only (Arm C).ResultsCommunity support for the integrated delivery was strong (e.g. 85% of focus group discussions concluded that it would result in people getting “two for one” health treatments). A high proportion of households participated in the integrated Arm A events (81.7% MDA, 80.4% MDRV), and these proportions were similar to those in Arms B and C. These findings suggest that coverage might not be reduced when interventions are integrated. Moreover, in addition to time savings, integrated delivery resulted in a 33% lower cost per deworming dose and a 16% lower cost per rabies vaccination.The median percentage of enrolled primary school children treated by this study was 76%. However, because 37% of the primary school aged children that received deworming treatment were not enrolled in school, we hypothesize that the employed strategy could reach more school-aged children than would be reached through a solely school-based delivery strategy.ConclusionsIntegrated delivery platforms for health interventions can be feasible, popular, cost and time saving. The insights gained could be applicable in areas of sub-Saharan Africa that are remote or underserved by health services. These results indicate the utility of integrated One Health delivery platforms and suggest an important role in the global campaign to reduce the burden of NTDs, especially in hard-to-reach communities.Trial registrationclinicaltrials.gov NCT03667079, retrospectively registered 11th September 2018.

COVID-19 in pastoral contexts in the greater Horn of Africa: Implications and recommendations

“…An ongoing wave of locusts in the GHA has led to the destruction of crops and pasture, with climate conditions expected to result in a dramatic increase in locust numbers during the coming months (Regional Desert Locust Alliance 2020). COVID-19 may limit entry into pastoral areas by Table 3 Examples of a One Health approach in pastoral areas in the GHA (Griffith et al 2020;Kamadjeu et al 2015;Lankester et al 2019;Mtui-Malamsha et al 2020;Musoke et al 2016;Ndejjo et al 2019;Onyango et al 2019 locust control personnel and result in personal protective equipment (PPE) "competition," as both locust control and health activities require PPE. Designation of locust control as essential can ensure access to pastoral areas, while a coordinated response by governments and development partners can help to ensure that PPE specialized for use in pesticide application is available (Regional Desert Locust Alliance 2020).…”

A One Health framework for integrated service delivery in Turkana County, Kenya

“…A One Health combined delivery platform for Maasai pastoralists combined mass drug administration for soiltransmitted helminths in humans and mass dog rabies vaccination in Tanzania. This approach was highly regarded among the community and saved costs and time (Lankester et al 2019). In Uganda, the integration of vaccination and health education to combat brucellosis was perceived by pastoralists and health service providers as feasible and desirable (Kansiime et al 2015).…”

One Health for neglected tropical diseases

“…In Tanzania, integrated delivery of human anthelminthic treatments through dog rabies control programmes proved to be popular as well as cost- and time-saving, also managing to reach children not enrolled in school who otherwise might be missed by school-based delivery strategies. 9 …”
