Understanding the Disease: Causes, symptoms, and transmission
East African Sleeping Sickness, known scientifically as Trypanosomiasis, is caused by the protozoan parasite Trypanosoma brucei gambiense and is primarily transmitted to humans through the bite of infected tsetse flies. This disease is prevalent in rural areas of East and Central Africa,with Zambia and Zimbabwe recently reporting cases,highlighting the ongoing risk in these regions. Contributing factors to the spread include poor agricultural practices,increased interaction with wildlife,and climate change,which may lead to the expansion of tsetse fly habitats.
Symptoms frequently enough manifest in two stages: the first stage presents with fever, headaches, and joint pains, typically resembling flu-like symptoms. If left untreated, it progresses to the second stage, affecting the central nervous system and causing serious neurological symptoms, such as confusion, poor coordination, and sleep cycle disturbances.Awareness of the symptoms is crucial, as early detection can considerably improve outcomes. The following is a summary of key symptoms:
| Stage | Symptoms |
|---|---|
| First Stage | Fever, headaches, joint pains, swollen lymph nodes |
| Second Stage | neurological symptoms, confusion, sleep disturbances, seizures |
