History of malaria control in Rwanda: implications for future elimination in Rwanda and other malaria-endemic countries

Abstract

Background Malaria was first reported in Rwanda in the early 1900s with significant heterogeneity and volatility in transmission over subsequent decades. Here, a comprehensive literature review of malaria transmission patterns and control strategies in Rwanda between 1900 and 2018 is presented to provide insight into successes and challenges in the country and to inform the future of malaria control in Rwanda. Methods A systematic literature search of peer-reviewed publications (Web of Knowledge, PubMed, Google Scholar, and the World Health Organization Library (WHOLIS) and grey literature on malaria control in Rwanda between 1900 and 2019 was conducted with the following search terms: “malaria”“, “Rwanda”, “epidemiology”, “control”, “treatment”, and/or “prevention.” Reports and other relevant documents were also obtained from the Rwanda National Malaria Control Programme (NMCP). To inform this literature review and evidence synthesis, epidemiologic and intervention data were collated from NMCP and partner reports, the national routine surveillance system, and population surveys. Results Two hundred sixty-eight peer-reviewed publications and 56 grey literature items were reviewed, and information was extracted. The history of malaria control in Rwanda is thematically described here according to five phases: 1900 to 1954 before the launch of the Global Malaria Eradication Programme (GMEP); (2) Implementation of the GMEP from 1955 to 1969; (3) Post- GMEP to 1994 Genocide; (4) the re-establishment of malaria control from 1995 to 2005, and (5) current malaria control efforts from 2006 to 2018. The review shows that Rwanda was an early adopter of tools and approaches in the early 2000s, putting the country ahead of the curve and health systems reforms created an enabling environment for an effective malaria control programme. The last two decades have seen unprecedented investments in malaria in Rwanda, resulting in significant declines in disease burden from 2000 to 2011. However, in recent years, these gains appear to have reversed with increasing cases since 2012 although the country is starting to make progress again. Conclusion The review shows the impact and fragility of gains against malaria, even in the context of sustained health system development. Also, as shown in Rwanda, country malaria control programmes should be dynamic and adaptive to respond and address changing settings.

The impact of Covid-19 on malaria services in three high endemic districts in Rwanda: a mixed-method study

“…Despite these efforts, Rwanda has experienced a dramatic upsurge in malaria cases between 2012 and 2017. During that period, malaria cases increased from 48 per 1000 population in 2012 to 406 per 1000 population at risk in 2017 (from 567,407 in 2012 to 4.8 million in 2017 [ 2 – 4 ].…”

Cone Bioassays Provide Reproducible Bioefficacy Estimates with Different Anopheline Mosquitoes and Can Be Used for Quality Assurance of Pyrethroid Insecticide Treated Nets

“…Nigeria, ITN quality control using a bioassay test was utilized after a long period of importation of nets with low bioe cacy [55]. It has also been hypothesized that the provision of lower e cacy nets has contributed to a signi cant rise of malaria cases in some high malaria burden countries including Nicaragua [56], Nigeria [55], PNG [41], Rwanda [57], Solomon of Islands [58]. Acceptable performance of ITNs is de ned by WHO as retention of biological activity (e.g.…”

Assessment of perinatal outcomes of pregnant women with severe versus simple malaria

“…There is currently a randomized control trial in Rwanda to examine the role of screening and treatment of asymptomatic pregnant women compared to routine care, which will examine whether perinatal outcomes are improved [ 23 ]. When malaria was less common in Rwanda, intermittent preventive treatment was not felt to be clinically appropriate and its use was stopped in 2008 [ 6 , 24 ]. Many factors have affected malaria rates in sub-Saharan Africa in the last decade and effective control requires dynamic health policies and economic investment which can integrate the necessary changes as well as deliver effective preventive and therapeutic measures.…”
