What is Malaria? Vector-borne disease caused by transmission of Plasmodium species by Anopheles mosquitoes. Plasmodium specie is the malaria parasite that causes malaria in humans Transmission occurs through mosquito bites on humans during blood meals Mosquitoes primarily breed in water Plasmodium sp. and Mosquito Life Cycle Images Retrieved from: 1. www.scienceblogs.com 2. Skeeters. www.bcps.org Global Epidemiological Background of Malaria Global and African Context: Malaria, a serious global concern particularly in Africa About half the world’s population (3.3 billion people) are affected by Malaria 216 million cases occurred in 2010; 81% in African region Malaria caused over 600,000 deaths in 2010; 91% in African region Third leading cause of death for children under 5 years Almost 1 out of 5 deaths of children under 5 in Africa is caused by Malaria 1.

Retrieved from: http://www.who.int/gho/malaria/en/index.html Nigeria Context of Malaria Burden Health Burden: Nigeria bears about 25% of the Malaria burden in Africa About 97% of the Nigeria’s population is at risk of Malaria Estimated 110 million malaria cases and 300,000 death annually Estimated 11% of maternal deaths is caused by malaria 1.

Brief Background of Anambra State Created in 1991 and Located in the South Eastern Nigeria Eight most populated state (4,055,048) and second most densely populated (840/km2) in Nigeria. Total area of 4,844 km2 Dominated by Igbos by tribe (98%) Capital City as Awka, while Onitsha and Nnewi are the biggest most commercial cities 1. National Population Commission [NPC] (2008). Demographic and Health Survey [DHS] 2008. Current Malaria Control Strategies in Anambra Most Malaria program in Nigeria, including the 1998 WHO RBM program adopted these Strategies: Diagnosis and treatment (D&T) with effective medicines Distribution and use of insecticide-treated nets (ITNs) to achieve coverage of populations at risk, with particular focus on Children under 5 and Pregnant women Indoor residual spraying (IRS) to curtail transmission Intermittent preventive treatment (IPT) 1. National Malaria Control Program [NMCP] (2012). Nigeria Malaria Indicator Survey 2010. Common Points of Interference for Malaria Controls Concerns No emphasis on the vectors life cycle (Weak intervention) Expensive particularly in poor regions (Cost of regular purchases and maintenance) compliance requirements. E.g. only 35% of the population in the South Eastern Nigeria use at least one bed net (NMCP, 2012). 1. Image retrieved from: www.crick.ac.uk 2. National Malaria Control Program [NMCP] (2012).

IPT, D&T High behavioral adherence / IPT, D&T Stakeholders of Malaria in Anambra State Government: Federal and State of Ministries of Health National and State Malaria Control Programs Local Health Departments Primary Health Care Departments Non Governmental Organizations (NGOs) Community based Non-Governmental Organizations Community groups and Coalitions Major Donor Agencies WHO USAID DFID World Bank Global Fund 1. National Malaria Control Program [NMCP] (2012). Nigeria Malaria Indicator Survey 2010. Environmental Management Control (EMC) Strategies Vegetation Clearance Fumigation of bushes Draining swamps Surface application of oil to open water bodies Modification of River boundaries Disposal of all potential open water storage facilities and objects away from residential area. 1.

Environmental Risk Practices in Anambra State Indiscriminate dumps of refuses and wastes close to residences Dumps in swamps and drainages causing stagnant waters Abandonment of vegetation's and bushes within residential areas. Farming within residential areas Efficacy and Cost Effectiveness of EMC Studies have shown that EMC in combination with quinine and ITN is capable of: Reducing malaria related incidence, morbidity, and mortality rates by 70 – 95% within 3 - 5 years Averting estimated 4173 deaths and 161,205 malaria attacks in one local community in 20 years Saving estimated $858 per death and $22.20 per attack . Averting disability adjusted life year (DALY) to the cost of $524 – 591 per DALY 1. Utzinger, J., Tozan, Y., & Singer, B. (2001). Efficacy and cost-effectiveness of environmental management for malaria control. Tropical Medicine & International Health: TM & IH, 6(9), 677-687. Other Advantages of EMC Strong benefits of the EMC strategy is the potential to: Leverage the available community resources; hence, saving great cost Create more effective community sustainability and ownership. Encourage sound community participation and communal efforts. Provide less stringent behavioral compliance No significant side effect Address other of other environmental issues unrelated to malaria. Recommendations for Malaria Eradication in our Communities First, malaria eradication, rather than malaria control should be emphasized in the state policy and strategic plan for communities. Channel more proportion of Malaria control donor and government funds to community EMC Empower and involve the State environmental Protection Agency (EPA) as active stakeholders in the fight against Malaria Strengthen the community participation in the community EMC Leverage the community resources to support this strategy Empower the community leaderships to support this course in every community. 1.

Do you understand the mosquito and malaria cycle? Do you understand the health and economic? burden of malaria in the World and Nigeria? Do you know the available malaria control measures in Anambra State and their Merits and Demerits? Do you know the advantages of EMC over others? Can you now make better informed and strategic decisions on the fight against malaria in your communities? 1. Utzinger, J., Tozan, Y., & Singer, B. (2001).
