African Sleeping Sickness
African Sleeping Sickness, scientifically known as Human African Trypanosomiasis, is a parasitic disease transmitted to humans through the bite of an infected tsetse fly.
This illness, endemic to certain regions of sub-Saharan Africa, poses a significant public health challenge due to its complex diagnosis and the severe neurological symptoms it can cause if left untreated.
Types of African Sleeping Sickness
There are two distinct subspecies responsible for the disease: Trypanosoma brucei gambiense and Trypanosoma brucei rhodesiense.
- Gambian Sleeping Sickness (Trypanosoma brucei gambiense): This form accounts for over 95% of reported cases. It is prevalent in West and Central Africa and progresses slowly, often taking years to manifest severe symptoms.
- Rhodesian Sleeping Sickness (Trypanosoma brucei rhodesiense): Found in Eastern and Southern Africa, this type is less common but more acute, with rapid symptom onset within weeks or months.

Get A Second OpinionSymptoms of African Sleeping Sickness
The clinical manifestations of African Sleeping Sickness vary between the two subspecies but generally occur in two stages: the hemolymphatic stage and the neurological stage.
Hemolymphatic Stage
In the initial stage, after the parasite enters the bloodstream, patients may experience:
- Fever
- Headache
- Joint pains
- Itching
Lymphadenopathy and hepatosplenomegaly are also common findings during this stage.
Neurological Stage
Once the parasites cross the blood-brain barrier, neurological symptoms become apparent. These include:
- Confusion
- Sensory disturbances
- Poor coordination
- Disturbances in sleep patterns, hence the name "Sleeping Sickness"
If untreated, the disease can lead to severe neurological damage and is often fatal.
Diagnosis of African Sleeping Sickness
Accurate diagnosis is crucial for effective treatment and involves several steps:
- Clinical Assessment: Initial suspicion based on symptoms and travel history to endemic areas.
- Laboratory Tests: Detection of trypanosomes in blood, lymph, or cerebrospinal fluid (CSF) through microscopic examination.
- Serological Tests: Antibody detection tests like the Card Agglutination Test for Trypanosomiasis (CATT) may be used, especially for T.b. gambiense.
- Staging: Determining the disease stage is essential for appropriate treatment, often requiring lumbar puncture to examine CSF for neurological involvement.
Treatment Options for African Sleeping Sickness
Treatment varies depending on the disease stage and subspecies:
Treatment for Gambian Sleeping Sickness
- First Stage: Pentamidine is commonly used and is effective with relatively mild side effects.
- Second Stage: Eflornithine or Nifurtimox-Eflornithine Combination Therapy (NECT) is recommended.
Treatment for Rhodesian Sleeping Sickness
- First Stage: Suramin is the drug of choice.
- Second Stage: Melarsoprol is used, although it is associated with significant toxicity.
It is imperative to monitor and manage treatment side effects, and follow-up care is essential to ensure recovery and prevent relapse.

Book an AppointmentPrevention and Risk Factors
Preventive measures focus on reducing contact with tsetse flies and controlling the vector population. Strategies include:
- Wearing long-sleeved clothing and using insect repellent
- Avoiding known tsetse fly habitats during peak activity times
- Implementing vector control programs such as insecticide-treated targets and traps
- Educating communities about the disease and its transmission
Risk factors include residing in or travelling to endemic regions, as well as engaging in activities that increase exposure to tsetse flies.
Complications of African Sleeping Sickness
If left untreated, African Sleeping Sickness can lead to severe complications, including:
- Chronic neurological damage
- Profound sleep disturbances
- Endocrine dysfunction
- Death
Early detection and treatment are critical to preventing these adverse outcomes.
Frequently Asked Questions
1. What are the symptoms of African Sleeping Sickness?
Symptoms may include fever, headaches, joint pain, and confusion, indicating potential infection requiring urgent medical attention.
2. What causes African Sleeping Sickness?
African Sleeping Sickness is caused by the Trypanosoma parasite, transmitted through the bite of infected tsetse flies, leading to systemic illness.
3. How is African Sleeping Sickness diagnosed?
Diagnosis typically involves blood tests and lymph node examination to confirm the presence of the parasite in the bloodstream.
4. What treatment options are available for African Sleeping Sickness?
Treatment may include antiparasitic medications, such as pentamidine or suramin, depending on the disease stage and symptoms.
5. What complications can arise from African Sleeping Sickness?
Complications may include neurological damage, sleep disturbances, and death if not treated promptly.
