Biology Topic: Malaria: Why do so many people still die of Malaria

Ross discovered the role played by mosquitoes in transmitting malaria. There are mainly four species of Plasmodium that cause malaria in which Plasmodium Falciparum is the most dangerous one. Recently, scientists discovered another dangerous species known as Plasmodium knowlesi which can also be life threatening. Medical practitioners opine that humans may get infected with more than one type of Plasmodium at a time. Although effective medicines have been developed for the treatment of this disease, any failure in timely diagnosis would make the disease dreadful. Why do so many people still die of malaria? In the opinion of Rietveld & Schlagenhauf (2008, p.214), malaria produces more complications in pregnant women and young children because these groups are more vulnerable to malaria. As mentioned above, malaria includes different categories among which cerebral malaria or brain malaria is the most dreadful one. Cerebral malaria produces notable changes in the mental status of the people affected and sometimes it may lead the patients to a coma stage. The mortality rate for this disease is 25-50% and an affected person would certainly die in 24-72 hours if he/she does not get proper treatment. The most horrible nature of this disease is that 15-20% victims of cerebral malaria die even if they are given medicine right time. The mortality rate of cerebral malaria still rises since medical science has not well identified the cause of this disease yet ( According to Bhatia (2002, p. 98), Blackwater fever is another complication of malaria in which red blood cells break and release hemoglobin directly into the blood. Progressively, this released hemoglobin reaches urine and it makes the urine very dark in appearance. If the patient does not get proper care in this condition, he may suffer from kidney failure too. Unfortunately, effective remedial measures to hemolytic crises of this disease have not been discovered yet. The rapid annihilation of red blood cells leads to other issues like hemoglobinemia, hemoglobinuria, and anuria and even death. Likewise, Pulmonary edema is an awful situation arising out of acute falciparum malaria and there is 80% possibility for associated deaths. This disease is characterized by the accumulation of fluid in lungs that damages the respiratory system of the affected person. We know that respiration is the inevitable part in the organic functioning of the human body because it is the process that provides sufficient oxygen to whole body cells. Doctors assert that pulmonary edema produces rapid deaths as compared to other related cases. Sometimes, very low blood sugar is reflected as the feature of malaria and it is a catastrophic complication of malaria as it may lead the affected person to a stage of coma. Some people may have large number of parasites in their blood; in such persons, the blood sugar level falls dangerously. In the opinion of Cotter (2001, p.39), hemolysis, which is the phenomenon of red blood cell breakage, is the direct cause of Blackwater fever. It also causes some horrible diseases such as intense jaundice and symptoms of anemia. Coagulopathy, also called bleeding disorders, is also a medical condition in which human body loses its ability to stop bleeding. It is observed that bleeding diseases sometimes appear as a result of malaria and gradually leads the affected person to death. The above described are the most complicated sides of malaria that often seem fatal in most of the cases. Social ...Show more
