Symptoms and Diagnosis of Plasmodium
Malaria is a disease caused by a protozoan parasite and transported by the Anopheles mosquito. Fever is the most common symptom of malaria. Other symptoms include arthralgia and vomiting. The most common diagnosis process for this disease is looking at the patient’s blood under a microscope. If microscopy is not available, antigen detection tests can be used.
In a year, there can be as many as five hundred million new cases of malaria, and of those five hundred million, 2.7 million die. That means, on average, a malaria-caused death happens once every twelve seconds. Malaria “threatens more than 40 percent of the world's population.” (“NIDCD,” 2002) So what exactly is malaria? What are its symptoms and how would someone diagnose this disease?
Malaria is a disease cause by a protozoan parasite. There are four species of these one-celled organisms that cause malaria in humans. They are known as Plasmodium; the most common is Plasmodium falciparum. To get inside our system, Anopheles mosquitoes are needed to transport this killer parasite.

Symptoms occur about ten to sixteen days after the mosquito bite. (“Malaria, 2002) Fever and classic flu symptoms begin. Symptoms sometimes follow a pattern of days where the attacks vanish and reoccur again. The period of time when the symptoms come and goes depends on the species of protozoa. For the parasites P. vivax and P. ovale, symptoms come and go for two days, and P. malariae has a three day period. Shivering occurs as well as head and muscle aches. The person infected becomes lethargic. Arthralgia and vomiting are other common symptoms of malaria. Because the parasite is invading and killing red blood cells, malaria can res...

transfer the parasite into human body thus causing malaria (Center of disease control and prevention, 2014). The parasite is called Plasmodium and it multiplies rapidly in the liver and then in red blood cells of an infected person and it causes symptoms like the flu, such as a high fever, chills, and muscle pain (CDC, 2014). There are four types of human malaria: Plasmodium vivax, P. malariae, P. ovale and P. falciparum. (WHO, Online Q&A, 2014). It’s predominantly found in countries like Africa, Southern
Other sign includes chills, sweats, myalgia, headache, nausea and vomiting and symptoms that indicate severe malaria are confusion, seizure, and shortness of breath. Some physical examination finding includes elevated temperature, diaphoresis, increases weakness, and enlarge spleen. Severe disease tangible result includes jaundice
especially after eating (WHO, 2010, p. 117). These symptoms started forty eight hours ago, and the patient has not taken any medication except for some aspirin. The patient has also been suffering from frequent fevers in the past two months. He has also suffered from frequent headaches but has always taken painkillers (Bloland & Williams, 2003, p. 58). On fevers, the patient has frequently visited a local health clinic that has never done any diagnosis but has given medication, which reduces the fever
include fever, inflammation, pain, fatigue, dizziness, nausea, and rashes, are evident to the patient. These symptoms offer important clues that help doctors and other health care professionals make a diagnosis. Many times, the symptoms point to several possible disorders. In those cases, doctors rely on medical tests, such as blood examinations and X rays, to confirm the diagnosis. Communicable diseases are caused by microscopic organisms. Physicians refer to these disease-causing organisms
medicines and also vaccines. Furthermore a combination of a mutation in genes and a selection pressure (pesticides) can lead to mosquitos becoming resistant and even more difficult to stop malaria from spreading. The parasites behind malaria are of the Plasmodium genus and once in a human body it targets erythrocytes (red blood cells). The spleen, which is responsible for filtering an individual’s blood, removes parasitized cells, therefore it is not uncommon for affected people to have anaemia. The ...
