African trypanosomiasis or Human African trypanosomiasis or HAT or Sleeping Sickness is a neurological disease caused by a parasite transmitted by the tsetse fly, and is only found in Sub-Saharan Africa.[1] African trypanosomiasis is caused by the trypanosoma brucei parasite, and control effects reduced cases to around 2,000 per year by 2019.[1] A related parasite causes American trypanosomiasis, alternatively known as Chagas disease.[2]

The most common form of African trypanosomia may not have major symptoms for many months or years, but symptoms emerge once the disease is advanced and cause central nervous system signs and symptoms.[3]

Signs and symptoms[edit | edit source]

African trypanosomiasis is fatal without treatment.[1]

=First stage[edit | edit source]

The trypanosomes (parasites) multiply in subcutaneous tissues, blood and lymph. Symptoms include:

=Second stage[edit | edit source]

The parasites cross the blood-brain barrier (BBB) and infect the central nervous system, this is known as the neurological or meningo-encephalic stage.

Symptoms become more obvious:

Treatment[edit | edit source]

There are two forms of African trypanosomiasis, and treatment depends on which form is presented. Drugs used for African trypanosomiasis are:

Suramin[edit | edit source]

Suramin is not available commercially, but has been identified as a potential medication to treat ME/CFS by research at the Open Medicine Foundation.[5]

ME/CFS[edit | edit source]

African trypanosomiasis is not known to occur with or be linked to the development of ME/CFS.[5]
