Swallowing air and belching are natural occurrences that result from eating or drinking too quickly. Chewing gum or drinking carbonated beverages can also introduce air into the stomach and cause belching. Because infants frequently swallow air when feeding, burping or belching is normal after they have been fed. The act of burping an infant helps relieve the discomfort caused by swallowed air.
Sleeping sickness, also known as Human African Trypanosomiasis (HAT), is caused by Trypanosoma brucei rhodensiense in Eastern Africa and Trypanosoma brucei gambiense in Western Africa . Both protozoan species are morphologically indistinguishable, but have drastically different epidemiological features.
Causal Agents: Protozoan hemoflagellates belonging to the complex Trypanosoma brucei. Two subspecies that are morphologically indistinguishable cause distinct disease patterns in humans: T. b. gambiense causes West African sleeping sickness and T. b. rhodesiense causes East African sleeping sickness.umans are the main reservoir for Trypanosoma brucei gambiense, but this species can also be found in animals. Wild game animals are the main reservoir of T. b. rhodesiense.
