Winterbottom's sign
From Wikipedia, the free encyclopedia
Winterbottom's sign is seen in the early phase of African trypanosomiasis, a disease caused by the parasites Trypanosoma brucei rhodiense and Trypanosoma brucei gambiense which is more commonly known as African sleeping sickness. Winterbottom's sign is the swelling of lymph nodes (lymphadenopathy) along the back of the neck, in the posterior cervical chain of lymph nodes, as trypanosomes travel in the lymphatic fluid and cause inflammation. The name originates from Chris Winterbottom, a parasitoligst who first developed the diagnostic technique, which is now used across Africa, for surveying the migration of the disease from endemic areas of those with preclinical infections.
