Malaria elimination is a critical public health goal, particularly in Africa, where the disease disproportionately affects vulnerable populations. Egypt’s success in achieving World Health Organization (WHO) malaria-free certification on October 20, 2024, through an evidence-based malaria elimination program, offers a valuable model for replication. This achievement marks a significant milestone in regional disease elimination efforts.
Historically, malaria was widespread in Egypt, particularly in the southern regions along the Nile River and Delta. Early efforts at control began in the early 20th century, focusing on vector reduction through drainage projects and larviciding. By 2024, Egypt was certified malaria-free by the World Health Organization (WHO), marking an important milestone in regional disease elimination efforts.
Egypt's victory brings hope to the fight against malaria; not only can public health interventions align with human rights, but they can create a sustainable model for health equity. Now that malaria is off the docket of issues Egypt faces, it is now time to focus on addressing other inequities the country is facing.
Given Egypt’s success, a study applies implementation science (IS) to retrospectively identify and analyze the key strategies that supported malaria elimination. The study focuses on three key implementation outcomes through an implementation science lens: fidelity, feasibility, and adaptability.

Key Strategies and Interventions
Egypt's elimination strategy comprised a combination of evidence-based interventions (EBIs), including indoor residual spraying (IRS), insecticide-treated nets (ITNs), larviciding, environmental modifications, and prompt case detection and treatment using chloroquine and sulfadoxine-pyrimethamine. Public health education campaigns and surveillance systems supported these efforts.
A combination of historical experience, epidemiological data, and operational research informed Egypt’s selection of specific elimination strategies during the 1970s and 1980s. The country conducted localized entomological and epidemiological studies to identify transmission hotspots and dominant vector species. This evidence-based approach allowed for the customization of interventions such as targeted indoor residual spraying, community-based surveillance, and stratified treatment regimens tailored to the local context.
Before mobilizing interventions, it is important to educate communities about what malaria is and develop trust in proposed interventions. The Egyptian government, in collaboration with different NGOs (Non-Governmental Organizations), launched different campaigns that reached communities all across the country; these talked about prevention, symptoms, and where people can find diagnostic centers. These were taught in schools, local community centers, and other locations to ensure that populations were able to access the information needed to become a part of the solution. These education opportunities are coupled with healthcare access and monitoring. By improving the healthcare infrastructure, treatment facilities were able to strengthen their interventions for those impacted by malaria. With the additional investment into data collection and monitoring systems, the Egyptian Ministry of Health was able to monitor trends in malaria incidence and collaborate with healthcare providers to mobilize and target interventions for those who need them most.
Vector control is noted to be central to Egypt’s strategy. Leveraging the use of insecticide-treated bed nets was the most prominent intervention; by 2019, 3 million of these nets had been distributed to reduce the incidence of malaria, especially in high-risk areas.
Implementation Science Approach
Our study is identified as an implementation study, evaluating the evidence-based interventions deployed, the implementation strategy tested, and its outcomes to provide insights for scaling similar programs across Africa. We adopted a retrospective implementation science approach to analyze Egypt’s malaria elimination program.

In addition to identifying core strategies, the study explores contextual factors-such as political commitment, health system integration, and community engagement-that acted as barriers or facilitators to implementation.
Study Design and Methods
Our study employed a retrospective mixed-methods implementation research design to evaluate Egypt’s malaria elimination program. The evaluation adhered to the Standards for Reporting Implementation Studies (StaRI) and was conducted between October 23, 2024, and November 30, 2024, following ethical approval granted on October 22, 2024, by the Federal Ministry of Health Nigeria Research Ethics Committee (FMOH-NREC; Approval No. FMOH/ER/2024/0456).
To guide the evaluation, we adopted a hybrid framework approach combining the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, and Maintenance) with Proctor et al.’s taxonomy of implementation outcomes.
Key Implementation Outcomes and Results
The implementation strategy focused on high-priority malaria-endemic regions, targeting vulnerable groups such as children under five and pregnant women. Interventions included vector control measures, such as insecticide-treated nets (ITNs), indoor residual spraying (IRS), antimalarial treatment protocols, and public health education campaigns. Key implementation strategies included workforce training, multilevel stakeholder engagement, integrated data-driven decision-making, and community mobilization.
The implementation strategy targeted populations in malaria-endemic regions, with a recruitment proportion of 92% (implementation evaluation group). The recipient population included rural communities primarily in the Nile Delta and southern Egypt, comprising 55% male and 45% female participants. Vulnerable groups, including children under five (37%) and pregnant women (12%), formed a significant proportion of the Population reached. These groups were prioritized due to their higher susceptibility to malaria and associated complications. The recruited Population exhibited diverse socioeconomic characteristics, with 65% living below the poverty line and 70% relying on subsistence farming for livelihood.

At the grassroots level, implementation was supported by a network of trained community health volunteers who conducted door-to-door visits, distributed ITNs, facilitated early symptom recognition, and promoted participation in indoor residual spraying (IRS) campaigns. Local healthcare providers received ongoing training to strengthen diagnostic capacity and ensure adherence to treatment protocols. However, staff shortages, inconsistent drug supply, and limited diagnostic tools occasionally hindered service delivery. Community engagement efforts were tailored to local norms, utilizing respected village leaders and religious figures to improve acceptance and trust in malaria interventions.
The primary effectiveness outcome was reduced malaria incidence, which declined by 96% over 15 years. Secondary outcomes included a 91% treatment rate for confirmed cases, increased community awareness of malaria prevention to 84% by the program’s end, and Integration of malaria control into the broader health system, improving surveillance and health workforce capacity.
For the intervention, vector population suppression was the primary target, evidenced by a 94% reduction in Anopheles mosquito density. Other key indicators aligned with outcomes include a 98% case detection rate within 48 hours (active surveillance outcome) and sustained community engagement (long-term sustainability metric).
Fidelity to the implementation strategy was 93%, and intervention delivery was 96% for ITN distributions and 91% for IRS applications.
The economic evaluation indicated high cost-effectiveness, with the program achieving $24 per disability-adjusted life year (DALY) averted for implementation and $18 per DALY for intervention activities. Resource allocation emphasized vector control (62%) and surveillance (28%).
Subgroup analyses revealed that urban populations had higher ITN adherence (89%) than rural areas (73%), likely due to better access and education. Community health workers and entomologists involved in nested implementation studies gained practical skills, reinforcing workforce capacity.
Routine monitoring systems, continuous feedback loops, and responsive adaptation mechanisms were central to achieving these outcomes.

Egypt’s Journey to Elimination and Sustaining Malaria-Free Status
Malaria has been traced as far back as 4000 B.C.E. in Egypt, with genetic evidence of the disease found in Tutankhamun and other ancient Egyptian mummies.
Early efforts to reduce human-mosquito contact in Egypt began in the 1920s when the country prohibited the cultivation of rice and agricultural crops near homes. With most of Egypt’s population living along the banks of the Nile River and malaria prevalence as high as 40%, the country designated malaria a notifiable disease in 1930 and later opened its first malaria control station focused on diagnosis, treatment and surveillance.
The construction of the Aswan Dam, completed in 1969, created a new malaria risk for the country, as standing water produced breeding grounds for mosquitoes. Egypt, in collaboration with Sudan, launched a rigorous vector control and public health surveillance project to rapidly detect and respond to malaria outbreaks.
By 2001, malaria was firmly under control and the Ministry of Health and Population set its sights on preventing the re-establishment of local malaria transmission. Egypt rapidly contained a small outbreak of malaria cases in the Aswan Governorate in 2014 through early case identification, prompt treatment, vector control and public education.
Egypt’s strong cross-border partnership with neighbouring countries, including Sudan, has been instrumental for preventing the re-establishment of local malaria transmission, paving the way for the country to be officially certified as malaria-free. In response to the armed conflict in Sudan that displaced thousands of civilians to Egypt starting in April 2023, the Egyptian Ministry of Health implemented an action plan to provide life-saving and supportive care, manage gender-based violence, and respond to malaria, leishmaniasis, and filariasis. Egypt provides free access to essential health services for migrants, regardless of their legal status.
The Government of Egypt is committed to preventing the re-establishment of malaria transmission. To maintain a robust surveillance and response system, the country has invested in ensuring continued capacity for malaria diagnosis, treatment, entomological surveillance and vector control. Egypt’s long-term cross-border partnership with neighbouring countries, including Sudan, has played a key role in preventing the re-establishment of local malaria transmission, paving the way for the country to be officially certified as malaria-free.
Contextual Factors and Challenges
Contextual challenges, such as political instability and funding fluctuations, occasionally disrupted operations. However, sustained international support (e.g., WHO partnerships) ensured supply chain continuity.
Lessons Learned and Adaptability
Egypt’s malaria elimination strategies exemplify the effective integration of implementation science into public health programs. Key success factors included community engagement, robust surveillance systems, and cost-effective resource allocation. The intentional use of implementation strategies and documented outcomes demonstrate alignment with the RE-AIM framework, reinforcing the program’s relevance for broader application.
However, drug-resistant forms of malaria and pesticide-resistant mosquito populations remain problematic. A sustainable strategy must be flexible, long-term, and context specific, focusing on community involvement, integration with current health systems, and responsive surveillance frameworks.
Recommendations for Other African Nations
African nations should adopt a multilayered proposition marked by capable leadership, flexible surveillance systems, demand-driven scientific research, capacity building, wide-ranging cooperation, gap analysis, strong healthcare systems, and community engagement.
For SSA, integrating these strategies with solutions for high transmission settings, such as vector-targeted interventions and responsive surveillance, is critical. Achieving this goal in SSA requires addressing unique challenges and tailoring interventions in the local epidemiological context.
