Essay / How Malaria Is Spread From Person to Person - 1250
Since the malaria parasite exists in human red blood cells which are part of the blood, it is possible that malaria is transmitted from one person to another person to another via organ transplantation. shared use of sharp objects that come into contact with blood, such as knives, needles and syringes; it can also be transmitted by blood transfusion. An infected mother can also pass malaria to her unborn baby during the birth (delivery) process. Malaria transmitted in this area is called congenital malaria. Because malaria can only be transmitted through blood, a person cannot “lock out” malaria. others simply by being near an infected person. You can kiss and hug a person infected with malaria without risk of infection, even if they cough or sneeze. ("Johns Hopkins Malaria Research Institute | About Malaria", pp. 1-2). )According to the World Health Organization; There are approximately 20 different locally known species of Anopheles around the world. All vector species feed at night. But although all Anopheles mosquitoes need a body of stagnant water to breed, each species. has his particular preference in matters of reproduction; for example, some prefer small, shallow collections of fresh water, such as rice fields, or those at Oshana in southern Africa. We find that the transmission rate is more concentrated in areas where the parasite has a chance of surviving longer. (The parasite needs a long lifespan so that it has enough time to replicate, mature, and complete growth inside the mosquito). The concentration of infection is also found to be higher in areas where the vector prefers to feed on humans rather than other animals. . For example, most published research suggests that the resilient habit of biting humans and the long lifespan of Africans...... middle of paper ......d red blood cells block blood flow in a blood vessel. The inset image shows a cross section of a sickle cell with abnormal hemoglobin (sickle) forming abnormal threads. (Tidy, Newson, & Gronow, 2012, p. 1-9) Sickle cell anemia is a type of anemia. When a person has anemia, they have a higher than normal number of red blood cells. However, anemia can also occur if your red blood cells contain an insufficient amount of hemoglobin. Red blood cells are produced in the spongy marrow located inside the body's largest bones. The bone marrow constantly makes new red blood cells to replace the destroyed ones. Normal red blood cells have a lifespan of 122 days. In addition to transporting and transporting oxygen, red blood cells also serve to remove waste from the body, for example red blood cells remove carbon dioxide.
