As a result of that fact, malaria in most cases gets the blame for fevers arising from other infections. In addition, malaria interferes with the treatment of other non malarial infections thereby; resulting into higher death rates from the other causes. Without forgetting, malaria has an enormous impact on the economy of most African countries. It slows down economic growth by 1% in African countries hence causing more than $ 1000 annually in per capita GDP. In 1970, 24 countries in the world had eliminated malaria completely. However, there were several countries in the other parts of the world especially; Africa had most of the countries. Malaria is an infection that caused by one of the four species of a parasite known as plasmodium. The four species include; Plasmodium vivax, P. falciparum, P. ovale, and P. malariae (Greenwood & Mutabinghwa 671). Transmission of the disease from one person to the other then occurs through the bite of an anopheles mosquito (David 1). Plasmodium enters the bloodstream of another individual only if the anopheles that bit him or her had previously bit a person who had malaria. Once the plasmodium finds its way into the bloodstream, it travels to the liver. This is the main part of the human body where plasmodium gets an opportunity to multiply rapidly. In a short period of a fortnight, thousands of plasmodia get back into the bloodstream. They then damage oxygen-carrying red blood cells hence resulting into anemia and high fever. After maturity of the disease causing microorganisms in the red blood cells, they rapture the cells and find their way back into the bloodstream. Damaged blood cells form small clumps that block blood vessels hence causing either kidney or brain damage. One of the species of plasmodium causes a detrimental infection known as falciparum malaria. This infection causes fatal blood vessels damage. Signs and symptoms of malaria sometimes seem to be vague. However, it is an undisputable reasoning that fever is one of the most conspicuous signs the disease. Other symptoms given consideration for include; increased sweating, headache, abdominal cramps, fatigue, dizziness, dry cough, joint pains, chills, pain from the back, myalgia, nausea, vomiting, cough, and diarrhea (Marcus & Alcamo & Heymann 46). If plasmodium falciparum does not get immediate treatment, it can result into a coma, pulmonary edema, and failure of the renal and even death. Despite the symptoms, physicians advocate for malarial diagnosis for those people who have the named symptoms. The symptoms do occur on the third day or any other day in the calendar. Fever in malaria normally develops remarkably early in the patients. There are numerous procedures used in the diagnosis of malaria the most common one being clinical diagnosis. Despite the fact that reliable diagnosis cannot be obtained on the basis of signs and symptoms alone, clinical diagnosis of malaria is much practiced in most malarial areas. In malarial endemic world, trained health care personnel and necessary facilities are inadequate. This therefore, means that the presumptive clinical diagnosis is one of the most realistic options. It is therefore, the commonest approach in the context of complex emergencies. This method offers the merits of speed, ease, and low costs. In areas that are common with malaria, clinical diagnosis ends up treating all patients with fever and other common malaria ...Download file to see next pagesRead More

Malaria is a disease caused by one of the four protozoan species of the genus Plasmodium. The four species are Plasmodium falciparum, P.ovale, P. malaria and P. vivax. It is a fatal disease that is caused by the parasite which infects the mosquito first. The mosquito then bites the human and transmits the parasites in the human blood.

Once in the human body, the parasites tend to multiply in the liver before infecting red blood cells (Malaria Consortium, 2007). Incidences of malaria can be found in any part of the world. However, it is more prevalent in some parts of the world compared to others.

When mosquito sucks blood from the human body, the protozoa enters human body. Due to the process of blood circulation, the parasite reaches to the liver of the person where it multiplies. It takes usually 9-16 days before it penetrates red blood cells causing them to breakdown.

Hence all efforts must be channeled to find a robust vaccine for preventing it. Hence, research in this area is going at an intense pace in recent years. But unfortunately, there are no foolproof vaccines that have been formulated yet. A vaccine by name RTS S/AS01, which was put to trial during 2009, is specifically addressed to vulnerable children in the Third World.

Once infection occurs, the sporozoite parasites are transported in the victim’s bloodstream to the liver where they mature into merozoites, which re-enter the bloodstream and infect the red blood cells (Shah, 2010). After multiplying in the cells, the parasites break out after 48 to 72 hours.
