Equatorial Guinea is scaling up a successful malaria control program from Bioko Island to its mainland, aiming for total elimination despite significant geographical and logistical challenges.
Key facts
- •Malaria prevalence on Bioko Island has dropped to approximately 7%, with child mortality under age 5 decreasing by 78%.
- •Oil companies including ConocoPhillips and Chevron have invested over $130 million in the Bioko program over the last 20 years.
- •The new $116 million mainland initiative is supported by a partnership between the government and private businesses.
- •WHO data indicates that African countries accounted for 95% of the 610,000 global malaria deaths in 2024.
- •Only Mauritius and Cabo Verde have been certified as malaria-free in sub-Saharan Africa.
Equatorial Guinea is expanding its malaria elimination program from Bioko Island to the country's mainland and Annobon Island. The initiative, which has successfully reduced malaria prevalence on Bioko, relies on indoor insecticide spraying, mosquito nets, and larval control. The government has secured $116 million in funding from state and business sources to support this nationwide rollout.
By the numbers
The Bioko Island Model
The program's success on Bioko Island is attributed to two decades of consistent funding, door-to-door community engagement, and meticulous data collection. Because the country lacks a formal address system, implementers from the nonprofit MCD Global Health created a custom mapping system to track house locations, spraying schedules, and infection cases. This data-driven approach allows for targeted interventions and real-time adjustments to control strategies.
Challenges of Mainland Expansion
Expanding the strategy to the mainland presents significant hurdles, including a territory 13 times larger than Bioko and porous borders with Cameroon and Gabon, where malaria remains prevalent. Experts note that while the island's geography naturally limits transmission from abroad, the mainland faces risks of reintroduction from neighboring countries. Additionally, specialists emphasize that effective elimination requires broader socioeconomic improvements, such as better housing and healthcare, to address the link between malaria and poverty.
Future Interventions and Goals
The expanded program will integrate the established spraying and surveillance methods with the rollout of the R21 vaccine for children, with a target of vaccinating 300,000 children. Authorities are also exploring advanced technologies, including the use of drones to identify mosquito breeding sites and the potential release of genetically modified mosquitoes designed to reduce transmission capacity.
