Final answer:
Sickle-cell anemia is a genetic blood disease characterized by the presence of abnormally shaped hemoglobin in red blood cells. The disease causes red blood cells to have a sickle-like shape, leading to oxygen delivery issues and various health problems. Typhoid is not related to sickle-cell anemia.
Step-by-step explanation:
The condition described in the question is sickle-cell anemia, not typhoid. Sickle-cell anemia is a blood disease that is characterized by the presence of an abnormally shaped hemoglobin protein in red blood cells. These abnormal red blood cells are sickle-shaped, causing them to get stuck in narrow blood vessels, leading to a lack of oxygen delivery to tissues and a variety of health problems.
Sickle-cell anemia is caused by a genetic mutation that affects the structure of the hemoglobin protein. This mutation leads to the production of hemoglobin S, which is responsible for the abnormal shape of red blood cells in individuals with sickle-cell anemia. The disease is particularly prevalent in individuals of African descent.
It is important to note that typhoid is an entirely different condition caused by the bacterium Salmonella enterica. It is not related to sickle-cell anemia or abnormal hemoglobin protein.
