The intermittent administration of seasonal malaria chemoprevention (SMC) is recommended to prevent malaria among children aged 3–59 months in areas of the Sahel subregion in Africa. However, the cost-effectiveness and cost savings of SMC have not previously been evaluated in large-scale studies. We did a cost-effectiveness and cost-savings analysis of a large-scale, multi-country SMC campaign with sulfadoxine–pyrimethamine plus amodiaquine for children younger than 5 years in seven countries in the Sahel subregion (Burkina Faso, Chad, Guinea, Mali, Niger, Nigeria, and The Gambia) in 2016. The total cost of SMC for all seven countries was $22·8 million, and the weighted average economic cost of administering four monthly SMC cycles was $3·63 per child (ranging from $2·71 in Niger to $8·20 in The Gambia). Based on 80% modelled effectiveness of SMC, the incremental economic cost per malaria case averted ranged from $2·91 in Niger to $30·73 in The Gambia. The estimated total economic cost savings to the health systems in all seven countries were US$66·0 million and the total net economic cost savings were US$43·2 million. Our interpretation is that SMC is a low-cost and highly cost-effective intervention that contributes to substantial cost savings by reducing malaria diagnostic and treatment costs among children.

Seasonal malaria chemoprevention (SMC) aims to prevent malaria in children during the high malaria transmission season. The Achieving Catalytic Expansion of SMC in the Sahel (ACCESS-SMC) project sought to remove barriers to the scale-up of SMC in seven countries in 2015 and 2016. We evaluated the project, including coverage, effectiveness of the intervention, safety, feasibility, drug resistance, and cost-effectiveness. SMC at scale was effective in preventing morbidity and mortality from malaria. Serious adverse reactions were rarely reported. Coverage varied, with some areas consistently achieving high levels via door-to-door campaigns. Markers of resistance to sulfadoxine–pyrimethamine and amodiaquine remained uncommon, but with some selection for resistance to sulfadoxine–pyrimethamine, and the situation needs to be carefully monitored. These findings should support efforts to ensure high levels of SMC coverage in west and central Africa.

AbstractTo maintain momentum towards improved malaria control and elimination, a vaccine would be a key addition to the intervention toolkit.

This survey assessed recently pregnant women's knowledge of malaria in pregnancy (MIP) and their experiences with community health workers (CHWs) prior to implementing community delivery of intermittent preventive treatment in pregnancy (cIPTp). Data were collected via a household survey in Ntcheu and Nkhata Bay Districts, Malawi, from women aged 16-49 years who had a pregnancy resulting in a live birth in the previous 12 months. A total of 370 women were interviewed. Women in both districts found their community health workers (CHWs) to be helpful (77.9%), but only 35.7% spoke with a CHW about antenatal care and 25.8% received assistance for malaria during their most recent pregnancy. A greater proportion of women in Nkhata Bay than Ntcheu reported receiving assistance with malaria from a CHW (42.7% vs 21.9%); women in Nkhata Bay were more likely to cite IPTp-SP as a way to prevent MIP (41.0% vs 24.8%) and were more likely to cite mosquito bites as the only way to spread malaria (70.6% vs 62.0%). Women in Nkhata Bay were more likely to receive 3 + doses of IPTp-SP (IPTp3) (59.2% vs 41.8%). Adequate knowledge was associated with increased odds of receiving IPTp3, although not statistically significantly so. Women reported positive experiences with CHWs, but there was not a focus on MIP. Women in Nkhata Bay were more likely to be assisted by a CHW, had better knowledge, and were more likely to receive IPTp3+ . Increasing CHW focus on the dangers of MIP and implementing cIPTp has the potential to increase IPTp coverage.

The Democratic Republic of the Congo adopted the strategy of using, at the community level, a dose of rectal artesunate as a pre-referral treatment for severe malaria amongst children under 5 years who could not quickly reach a health care facility and take oral medication. However, the adherence to referral advice after the integration of this strategy and the acceptability of the strategy were unknown. To assess adherence by the mothers/caretakers of children under 5 years to referral advice provided by the community health workers after pre-referral treatment of severe malaria with rectal artesunate, the authors conducted a noninferiority community trial with a pre- and post-intervention design in 63 (pre-intervention) and 51 (post-intervention) community care sites in 4 provinces (Kasaï-Oriental, Kasaï-Central, Lomami, Lualaba) from August 2014 through June 2016. The integration of pre-referral rectal artesunate for severe malaria into the community care site in the DR Congo is feasible and acceptable. It positively affected adherence to referral advice. However, more health education is needed for parents of children under 5 years and community health workers.

AbstractMalawi is midway through its current Malaria Strategic Plan 2017–2022, which aims to reduce malaria incidence and deaths by at least 50% by 2022. Malariometric data are available with health surveillance data housed in District Health Information Software 2 (DHIS2) and household survey data from two recent Malaria Indicator Surveys (MIS) and a Demographic and Health Survey (DHS).

Community health worker (CHW) interventions to manage childhood illness is a strategy promoted by the global health community, which involves training and supporting CHW to assess, classify, and treat sick children at home. To inform CHW policy, the Government of Tanzania launched a program in 2011 to determine if community case management (CCM) of malaria, pneumonia, and diarrhea could be implemented by CHW in that country. This paper reports the results of an observational study on the CCM service delivery quality of a trial cohort of CHW in Tanzania, called WAJA. In the majority of cases, WAJA correctly assess sick children for CCM-treatable illnesses (malaria, pneumonia, and diarrhea) and general danger signs (90% and 89%, respectively), but too few correctly assess for physical danger signs (39%). In majority of cases (78%) WAJA treated children correctly (84% of malaria, 74% pneumonia, and 71% diarrhea cases). Errors were often associated with lapses in health systems support, mainly supervision and logistics. For CCM to be effective, in Tanzania, a strategy to implement it must be coordinated with efforts to strengthen local health systems.

In 2013, the Guinean health authority had to reorganise and run a national response against malaria as a priority. The review of the National Strategic Plan to fight malaria in Guinea was carried out and one of its critical components was the prevention and rapid management of fever (RMF) attributable to malaria in children. The study reports on the demographic and health determinants of this rapid management in children under 5. The participants were 4786 children from 2874 representative households. RMF was defined in terms of recourse to primary care. The recourse was defined by child's reference for the treatment of fever which led or not to treatment of malaria. We found that 1491 children (31.2%) had a bout of fever within the 2 weeks that preceded the survey. The prevalence of malaria was 45.4% among those children who have a bout of fever. The recourse to traditional healers was estimated at 9.6% and the use of health facilities was estimated at 71.5%. Overall, 74.9% of children with fever received treatment within the recommended timeliness (24 h), with regional disparity in this rapid response. The high proportion of recourse to traditional healers is still a matter of concern. New control and prevention strategies should be extended to traditional healers for their training and involvement in directing febrile children to health facilities.

Malaria accounts for the largest portion of healthcare demand in Angola. Cross-sectional health facility surveys were performed in low-transmission Huambo and high-transmission Uíge Provinces in early 2016. In each province, 45 health facilities were randomly selected from among all public health facilities stratified by level of care. The results reveal important diferences between provinces. Despite similar availability of testing and ACT, testing and treatment rates were lower in Huambo compared to Uíge. A majority of true malaria cases seeking care in health facilities in Huambo were not appropriately treated with anti-malarials, highlighting the importance of continued training and supervision of healthcare workers in malaria case management, particularly in areas with decreased malaria transmission.

The neglected tropical diseases (NTDs) are the most common infections of humans in sub-Saharan Africa. Virtually all of the population living below the World Bank poverty figure is affected by one or more NTDs. New evidence indicates a high degree of geographic overlap between the highest-prevalence NTDs (soil-transmitted helminths, schistosomiasis, onchocerciasis, lymphatic filariasis, and trachoma) and malaria and HIV, exhibiting a high degree of co-infection. Recent research suggests that NTDs can affect HIV and AIDS, tuberculosis (TB), and malaria disease progression. A combination of immunological, epidemiological, and clinical factors can contribute to these interactions and add to a worsening prognosis for people affected by HIV/AIDS, TB, and malaria. Together these results point to the impacts of the highest-prevalence NTDs on the health outcomes of malaria, HIV/AIDS, and TB and present new opportunities to design innovative public health interventions and strategies for these "big three" diseases. This analysis describes the current findings of research and what research is still needed to strengthen the knowledge base of the impacts of NTDs on the big three.
