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

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

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

Nigeria Context of Malaria Burden…2

Economic burden:


Costs can be divided into direct and indirect cost

Direct costs – households and government expenditures on treatment and prevention

Indirect costs – losses of labor productive time due to mortality and morbidity
Nigeria Government losses close to $1 billion ($868,421,052) annually (Jimoh, et al,
2007)

In general context (Other studies outside Nigeria):

Monthly expenditure on malaria treatment is between $0.41 and $3.88 per person

Treatment equivalent between $1.88 and $26 per household (Chima, et al, 2003)

Very poor households spend 28% of their income on Malaria

In Africa, government spend estimated $1.83 and $8.01 per person (Shepard, et al,
1991)

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

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)

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).

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.

International Health: TM & IH, 6(9), 677-687.
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

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.
