Sustained political instability and violence have massive impacts on the health of the people affected.
Studies show that more die from treatable diseases during conflict than they do from conflict-related casualties.
Poor state of healthcare facilities often deteriorates to a point where diseases that require only basic treatment such as malaria or diarrhea cannot be cured.
The association between conflict and infectious disease are particularly prevalent in Africa.
Ongoing civil conflict, and infectious disease remain important contributors to national mortality.

IINTRODUCTION
Conflict and war are recognized as determinants of infectious disease risk.
Sleeping sickness re-emerged in sub-Saharan Africa since the 1970’s.
It has coincided with extensive civil conflict in affected regions.

INTRODUCTION
Factors that increase the incidence of outbreaks during outbreaks include;
decreased hygiene dietary deficiencies decline of health services travel insecurity reduced access of
humanitarian support reduced veterinary and
zoonoses control internal displacement of
populations into marginal areas.

INTRODUCTION
DISEASE DEFINITIONA protozoan
parasitic disease.It affects humans,
livestock and a large number of sylvatic species in much of sub-Saharan Africa

MODE OF TRANSMISSIONTransmitted by the
tsetse fly vector trypanosomiasis.
There are two sub-species of human-infectious trypanosomes;T.b. gambienseT.b. rhodesiense

DISEASE SYMPTOMS
Stage one symptoms include; fever, headaches and joint pains.
These symptoms are often mis-diagnosed as malaria.
If untreated, the disease parasite passes through the blood-brain barrier and into the nervous system.

Stage two symptoms include;
confusion reduced
coordinationdisturbed sleep
cycle with bouts of fatigue
manic periods,daytime slumber and night-time insomnia.

DISEASE SYMPTOMS

TREATMENT
Sleeping sickness treatment is expensive, complicated and can be dangerous for the patient.
The dominant treatment for late-stage sleeping sickness is melarsopol.
This is, an organ arsenic compound with high toxicity and varying rates of treatment failure.

TREATMENTSleeping sickness is
problematic because laboratory facilities are required to diagnose the disease
A lumbar puncture may also be needed to differentiate between stages 1 and 2
Treatment is relatively less complicated and still effective for patients at stage 1. but very difficult at stage 2.

GEOGRAPHICAL DISTRIBUTION First identified and characterized in
Africa in the last part of the 19th century.
Widespread and severe epidemics of the disease in Kenya, Tanzania, Uganda, Nigeria, and the Democratic Republic of the Congo.
The disease generally brought under control by the 1960s in much of Africa but has re-emerged in many countries since the 1970s.
Re-emergence is due to post-independence turbulence, unstable governments, limited public health resources, and re-allocation of domestic and international funding towards malaria, HIV/AIDS, and tuberculosis.
In areas of Sudan, the Democratic Republic of the Congo, and Angola, sleeping sickness occurs in epidemic proportions and is the greatest cause of mortality

CASE IN POINT SOUTH-EASTERN UGANDA T.b.rhodesiense epidemic in 1976-
1990s coincided with political instability and civil war during and after the rule of Idi Amin.
The civil war influenced the transmission of sleeping sickness by;
Breakdown of veterinary and public health services
Collapse of vector control, re-growth of bushy tsetse habitat in abandoned agricultural fields
Increasing displacement of human and animal populations into marginal or swampy areas where they are more likely to be bitten by flies

HURDLES TO INTERVENTION AND PREVENTIONTransmission determinants
of sleeping sickness include the following; Land cover change i.e.
increased vegetation growth around homesteads and the resulting movement of tsetse flies into peridomestic environments.
Collapse of essential health services, and veterinary and vector control
Reduced surveillance and treatment in both humans and animal reservoirs of infection.
Ford, L.B., (2007). Civil conflict and sleeping sickness in Africa in general and Uganda in particular; Conflict and Health 2007, 1:6 doi:10.1186/1752-1505-1-6
Insecurity due to conflict constrains the capacity of both national governments and external organizations to respond to outbreak situations.
Lack of harmonization and integration of activities between organizations trying to control the disease.
Absence of appropriate administrative infrastructures for program implementation.
SOLUTIONSEfforts to prevent and control sleeping sickness must;
Identify and integrate knowledge of the processes by which conflict affects disease
Increase drug development
Re-establish essential health services and active surveillance and treatment
Target outbreak locations and areas bordering countries with high incidence

BREAKTHROUGH TREATMENTNECT (Nifurtimox-Eflornithine
Combination Therapy), the first new treatment in 25 years against Human African trypanosomiasis is now available.
Endemic countries have now begun the process of ordering the new combination treatment and kits through WHO.
NECT cuts the cost of treatment by half and significantly reduces the burden on health workers.

CONCLUSIONThe campaign to eliminate the tsetse vector from the African
continent will face enormous hurdles due to continued conflict.
Progress to curb sleeping sickness is more likely to come from;
a. Political stabilization in affected countries. b. Local interventionsc. Development of administrative policy, capacity,
integration, and infrastructure to implement localized control strategies
d. Prevention and control campaigns that address conflict-related drivers of disease risk.
e. An understanding of areas where conflict may contribute to increased disease risk
