Symptoms Of African Trypanosomiasis

Swollen Lymph Nodes

Swollen lymph nodes are present in both types of African trypanosomiasis and occur during the first stage of the illness. The lymph nodes located at the back of the neck, known as the posterior cervical and supraclavicular nodes, are the most common site for swelling in the West African type of the condition. Swelling at these locations is referred to as the 'Winterbottom sign.' In the East African form of sleeping sickness, enlarged lymph nodes are most common at the elbow and in the armpit; these nodes are known as the epitrochlear nodes. Facial swelling can also occur, and an enlarged spleen may sometimes accompany this. Taking a sample of fluid from some of the swollen lymph nodes can aid in diagnosis.
