“…Distance and safety are two barriers to malaria professionals and health managers being able to provide continuous or even timely onsite medical support. Many studies have found significant morbidity and mortality among expatriate populations owing to malaria [7, 8], and lower KAP levels for prevention and treatment of malaria among non-immune travellers and expatriate workers [14]. Previous studies on health education strategies for malaria prevention have proved to be effective in improving malaria prevention KAP and decreasing rates of malaria morbidity [50, 51].…”

BackgroundMalaria is the main health risk for Chinese expatriates working in Niger. Health education is a recommended intervention for prevention of malaria among non-immune travellers and expatriate workers. It is urgent to develop an effective and feasible way for these populations to obtain information about the prevention and treatment of malaria.MethodsAn individually randomized, unblinded, controlled trial was used to evaluate the effectiveness of using WeChat official accounts for health education to improve malaria health literacy among Chinese expatriates in Niger. A total 1441 participants completed a baseline malaria health literacy questionnaire and were randomly assigned to an intervention or comparison group in a ratio of 1:1. From July to October 2014, 50 malaria prevention and treatment messages were sent to the intervention group; 50 health news messages were concurrently sent to the control group. Both groups completed the malaria health literacy questionnaire again 4 months after the start of the education intervention. A questionnaire addressing satisfaction with the health education programme was completed by the intervention group. Malaria morbidity data for 2013 and 2014 were also collected.ResultsAt baseline, participant health literacy rates were 58.29, 62, 54, and 34% for skills, knowledge, practice, and attitude, respectively. After the intervention, rates for all four aspects of malaria literacy were above 70%. There was greater change in knowledge, attitude, practice, skills, and overall health literacy among the intervention group compared with the controls, with a statistically significant difference (p < 0.01). This was especially true for acquisition of malaria-related knowledge, practice and attitude; comprehensive intervention practices; and, correct use of rapid diagnostic tests (p < 0.001). The reported malaria morbidity during the study period decreased from 23.72 to 15.40%. Participants reported high levels of satisfaction with the WeChat health education programme with over 80% stating that they would continue to follow the programme.ConclusionsThe present health education intervention, via a WeChat official account, for the prevention and treatment of malaria among non-immune travellers and expatriate workers proved to be an effective, sustainable, feasible, and well accepted strategy for improving malaria health literacy among Chinese expatriates in Niger.

Ghana is classified as being in the malaria control phase, according to the global malaria elimination program. With many years of policy development and control interventions, malaria specific mortality among children less than 5 years old has declined from 14.4% in 2000 to 0.6% in 2012. However, the same level of success has not been achieved with malaria morbidity. The recently adopted 2015–2020 Ghana strategic action plan aims to reduce the burden of malaria by 75.0%. Planning and policy development has always been guided by evidence from field studies, and mathematical models that are able to investigate malaria transmission dynamics have not played a significant role in supporting policy development. The objectives of this study are to describe the malaria situation in Ghana and give a brief account of how mathematical modelling techniques could support a more informed malaria control effort in the Ghanaian context. A review is carried out of some mathematical models investigating the dynamics of malaria transmission in sub-Saharan African countries, including Ghana. The applications of these models are then discussed, considering the gaps that still remain in Ghana for which further mathematical model development could be supportive. Because of the collaborative approach adopted in their development, some model examples Ghana could benefit from are also discussed. Collaboration between malaria control experts and modellers will allow for more appropriate mathematical models to be developed. Packaging these models with user-friendly interfaces and making them available at various levels of malaria control management could help provide the decision making tools needed for planning and a platform for monitoring and evaluation of interventions in Ghana.

“…Impressive stories from Brazil and Egypt following its impactful malaria eradication motivates its revival [10] with current operation in Kenya [11], The Gambia [8], Burkina Faso, Benin [12] and Tanzania [13]. Low immobility, confinement to shallow water bodies, susceptibility to chemical attacks and less chances of developing resistance favor this vector control approach [14, 15].…”

BackgroundVector control remains the mainstay to effective malaria management. The negative implications following persistent application of synthetic insecticides geared towards regulation of mosquito populations have necessitated prospection for ecofriendly effective chemistries. Plant-derived compounds have the potential to control malaria-transmitting mosquito populations. Previously, Agerantum conyzoides extracts have demonstrated toxicity effects on disease-transmitting mosquitoes. However, their efficacy in controlling Afrotropical malaria vectors remains unclear. Herein, the toxicity and growth disruption activities of crude methanolic leaf extract of A. conyzoides on Anopheles gambiae sensu stricto and An. arabiensis larvae were assessed. MethodsLate third (L3) instars of An. gambiae s.s and An. arabiensis larvae were challenged with increasing doses of crude methanolic extract of A. conyzoides. The larval mortality rates were recorded every 24 h and the LC50 values determined at their associated 95% confidence levels. ANOVA followed by Post-hoc Student-Newman-Keuls (SNK) test was used to compare results between treatment and control groups. Phytochemical profiling of the extract was performed using standard chemical procedures.ResultsTreatment of larvae with the methanolic extract depicted dose-dependent effects with highest mortality percentages of ≥ 69% observed when exposed with 250 ppm and 500 ppm for 48 h while growth disruption effects were induced by sublethal doses of between 50–100 ppm for both species. Relative to experimental controls, the extract significantly reduced larval survival in both mosquito species (ANOVA, F(8,126) = 43.16776, P < 0.001). The LC50 values of the extract against An. gambiae s.s ranged between 84.71–232.70 ppm (95% CI 81.17–239.20), while against An. arabiensis the values ranged between 133.46–406.35 ppm (95% CI 131.51–411.25). The development of the juvenile stages was arrested at pupal-larval intermediates and adult emergence. The presence of alkaloids, aglycone flavonoids, triterpenoids, tannins and coumarins can partly be associated with the observed effects.ConclusionThe extract displayed considerable larvicidal activity and inhibited emergence of adult mosquitoes relative to experimental controls, a phenomenon probably associated with induced developmental hormone imbalance. Optimization of the bioactive compounds could open pathways into vector control programmes for improved mosquito control and reduced malaria transmission rates.
