Published: Mapping Schistosomiasis and Soil Transmitted Helminthiasis in Angola

New research on Neglected Tropical Disease (NTD) control in Angola was recently published, enabling health officials to accurately plan and implement activities that significantly reduce the burden of Schistosomiasis (SCH) and Soil Transmitted Helminthiasis (STH) in the country.

These two articles contain results from the first country-wide (18 provinces) mapping of Schistosomiasis and Soil Transmitted Helminthiasis using WHO mapping guidelines.

The first paper, published in Infectious Diseases of Poverty, outlines the initial mapping of these diseases in 2014. This mapping took place across three provinces and formed the baseline for the programme MENTOR subsequently implemented in Angola.

The MENTOR Initiative team, together with National NTD programme, local provincial programmes and funding from The END Fund, carried out the work.

Results outlined the high prevalence, though focal, of Schistosomiasis in several districts of Uige and Huambo. A high prevalence of STH was found across the three mapped provinces highlighting the need to scale up Mass Drug Administration campaigns in endemic areas; together with sustained Water, Sanitation and Hygiene (WASH) and Information Education and Communication (IEC) activities.

The paper was written in collaboration with University of New South Wales who provided technical support for data analysis and report writing.

The second paper, published in PLOS Neglected Tropical Diseases, outlines mapping conducted in 2018/2019 across 15 provinces of Angola. This exercise, led by Angola NTD programme, and supported by the Expanded Special Project for Elimination of Neglected Tropical Diseases (ESPEN) has been key to the scale up of Mass Drug Administration campaigns in Angola. Campaigns have gradually increased from the initial three provinces in 2014 to nine provinces in 2022. MENTOR and The END Fund provided technical and logistical support to the mapping.

Dr Elsa Palma Mendes, NTD Mapping and MDA Coordinator with MoH Angola, said: “This publication shows a great effort from the NTD Programme in Angola alongside its partners, to update the epidemiological profile of Schistosomiasis and Soil Transmitted Helminthiasis.

“The results from this mapping will enable the implementation of strategies to control these diseases so that they are no longer a public health problem in Angola. Results and strategies are in line with key actions and milestones defined by WHO in its 2021-2030 roadmap.”
