Symptoms of the disease begin to occur shortly after being bitten. A chancre forms around where the person has been bitten and soon the parasite enters the lymphatic system. The immune response it triggers in the immune system causes the lymph nodes to swell especially on the necks. The severe swelling of the lymph nodes on the dorsal side of the neck is known as Winterbottom’s sign, and is a tell-tale sign of sleeping sickness. The parasite soon finds its way into the blood stream after invading the lymphatic system. From the bloodstream, the parasite is free to travel and harm any organ and cause damage all throughout the body. The parasite targets smooth and skeletal muscle and is often fatal because of the damage it causes to cardiac muscle.
