Is there a vaccine for sleeping sickness?
There is no vaccine or drug for prophylaxis against African trypanosomiasis. Preventive measures are aimed at minimizing contact with tsetse flies.
Which organ is affected by sleeping sickness?
Sleeping sickness is an infection caused by tiny parasites carried by certain flies. It results in swelling of the brain.
Does sleeping sickness make you sleep?
Once the brain is affected it results in changes in behaviour, confusion, poor coordination, difficulties with speech and disturbance of sleep (sleeping through the day and insomnia? at night), hence the term ‘sleeping sickness’.

In the second stage the parasites cross the blood-brain barrier to infect the central nervous system. This is known as the neurological or meningo-encephalic stage. In general this is when more obvious signs and symptoms of the disease appear: changes of behaviour, confusion, sensory disturbances and poor coordination.
What happens in African sleeping sickness?
Fever, severe headaches, irritability, extreme fatigue, swollen lymph nodes, and aching muscles and joints are common symptoms of sleeping sickness. Some people develop a skin rash.

Is African trypanosomiasis a virus or bacteria?
African trypanosomiasis, also known as African sleeping sickness or simply sleeping sickness, is an insect-borne parasitic infection of humans and other animals. It is caused by the species Trypanosoma brucei. Humans are infected by two types, Trypanosoma brucei gambiense (TbG) and Trypanosoma brucei rhodesiense (TbR).
How is sleeping sickness diagnosed?
CSF testing is done after a parasitologic diagnosis has been made by microscopic examination of blood, lymph node aspirates, chancre fluid, or bone marrow or when indications of infection are present that justify a lumbar puncture (e.g., clinical signs and symptoms of sleeping sickness or strong serologic suspicion).
What 3 types of diseases does Trypanosoma cause?
Trypanosomes infect a variety of hosts and cause various diseases, including the fatal human diseases sleeping sickness, caused by Trypanosoma brucei, and Chagas disease, caused by Trypanosoma cruzi.
Who are the most common victims of African sleeping sickness?
The only people at risk for African sleeping sickness are those who travel to Africa. That’s where the tsetse fly is found. The parasites that cause the disease are passed on only by the tsetse fly.
What causes African trypanosomiasis?
African Trypanosomiasis, also known as “sleeping sickness”, is caused by microscopic parasites of the species Trypanosoma brucei. It is transmitted by the tsetse fly (Glossina species), which is found only in sub-Saharan Africa.
Does sleeping sickness kill?
The reason sleeping sickness is so deadly is that it can enter the brain. There it causes its most severe symptoms, such as confusion, hallucinations and poor coordination. Once in the brain it becomes harder to treat, and therefore more likely to be fatal.
