Why is malaria particularly harmful to the poorest Ethiopians?
- They have limited access to effective mosquito repellents.
- They are more vulnerable to the parasite due to poor nutrition.

Study Notes
Malaria in Ethiopia
- Malaria thrives in warm, humid climates with stagnant water, ideal for mosquito breeding.
- In Ethiopia, altitude influences malaria prevalence. Lowland areas with higher temperatures and humidity have high endemic rates, while highland areas with lower temperatures slow mosquito and parasite development, resulting in lower rates.
- Population movement, urbanization, irrigation, and misuse of antimalarial drugs contribute to malaria spread.
- Seasonal factors, such as harvest and planting times, increase malaria transmission, especially impacting the poor, due to living conditions and increased mosquito activity.
- Ethiopia has approximately 5 million malaria cases and 70,000 deaths annually. Sub-Saharan Africa loses approximately US$12 billion annually due to lost productivity.
- Malaria absorbs a significant portion of national health expenditures in Ethiopia (40%), impacts hospital admissions (10%), and clinic visits (12%).
- Malaria in western lowlands limits resources in agriculture, influencing population movement and land degradation.
- Irrigation projects, urbanization, and rice cultivation expand mosquito breeding grounds.
- Malarial parasites are increasingly drug-resistant. Significant anti-malarial drug advancements were made nearly 50 years ago.
- Malaria is endemic in 75% of Ethiopia's land area, affecting two thirds of the population. Highest risk areas are in western lowlands (Tigray, Amhara, and Gambella provinces).
- Transmission peaks following the rainy season (June-November).
- Malaria transmission is seasonal in the midlands (1000-2200m altitude), with occasional epidemics
- Arid climates in the eastern lowlands (Afar and Somali provinces) confine malaria to river valleys.
- Malaria is the deadliest disease globally.
- It has two hosts: Anopheles mosquitoes and humans.
- Two dominant types in Ethiopia: Falciparum (60%) and Vivax (40%). Artemisinin-based combination therapies are the standard for uncomplicated Falciparum, while Chloroquine is used for Vivax.
- Prevention methods include insecticide-treated mosquito nets (ITNs), indoor residual spraying (IRS), and mosquito larval source reduction.
- A 2015 survey indicated over 70% of households in endemic areas used ITNs or IRS. Protection rates have recently slowed.
- Ethiopia aims to eliminate malaria by 2030, using existing control activities.
- The 2019 initiative was focused on reducing malaria incidence by 40% in 2020.
Challenges and Factors
- Insecticide resistance in mosquitos
- Migrant populations
- Emerging Chloroquine resistance to P. Vivax
- Controlling and eliminating P. Vivax is a global challenge
