According to the World Health Organization (WHO), 214 million cases of malaria reported in 2015, with mortality count has risen to more than 438,000 people dying from Malaria (parasite transmitted by mosquitos). Ninety-one percent of these deaths occurred in sub-Saharan Africa. Despite disease mortality rates falling by 37 percent since 2000, a child in Africa still dies every minute from malaria.
What is malaria? A deadly disease that was once has taken many lives, which are long forgotten in this day of age. Malaria once considered as one of the world's most dangerous tropical parasitic diseases. It claims more lives than any other communicable disease other than tuberculosis. It more prominent in Africa and other under developing countries,

The WHO reported that there was a seventeen percent of globally declining in malaria incidence between the year of 2000 and 2010, which was significantly lower than the proposed target of fifty percent rate (WHO, 2012). This statistical data reveals that many hurdles remain to overcome. However, an encouraging reduction of 33% in the malaria-specific mortality rate has observed in the African region. The RBM (Roll Back Malaria) initiative foresees the need for continuation of malaria control efforts until global malaria eradication can be obtainable in the long-term. However reaching the RBM goal will necessitate an increase in funding resources, a marked economic progress in countries with extreme poverty, and the maintenance or increase of the long-lasting insecticide-treated net coverage. (WHO, …show more content…
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 and focal neurologic signs. CDC recommends that testing for the disease should be done microscopically on the same day the patient present for care. Microscopic blood smear sample is the gold standard to diagnose disease. Follow by RDT (rapid diagnostic test) a P. falciparum antigen detection, which allows faster diagnosis of malaria when the microscope is no readily available, molecular diagnostic by looking into the polymerase chain reactions and antibody detection test which is only useful when diagnosing past infections, but not recommend to diagnose acute malarial
the definition of parasite, is something that hurts. for ever. this parasite, was a landmine. I had good medical attention. But once i returned home, I finally left. I wanted to leave. there were rockets, raining down in every place i looked. those rockets stole my family. we couldn't stay. so we fled. the last time i had a true education, was when i entered high school. between 2nd grade and 9th the education i had in my birth place, that wasn't any kind of education. i wanted more. and there was nothing there for me to want
With no treatment half of patients who enter the second phase die within ten to fourteen days. Similar to yellow fever, malaria was transmitted to humans through mosquito bites, causing symptoms such as fever, fatigue, and vomiting. Difficult to recognize at first malaria continues to cause yellowing of the skin, seizures, and even death; these symptoms normally begin after ten to fifteen days after being contracted. Malaria was brought over to early America through slavery and killed millions of people between the seventeenth and twentieth century. Throughout the growth and expansion of America there was been several disease outbreaks both endemic and epidemic such as small pox, measles, yellow fever, and malaria. Starting with the Colombian exchange and slavery these diseases were brought to the new world and spread like wildfires that devastated populations both native and nonnative. Most commonly known for the death toll on the native Americans these diseases were so costly due to low resistance, poor sanitation, and inadequate
What kills more than two thousand children a day could potentially spread around the world. All of the most effective drugs used on this disease in the last evades have gradually been rendered useless by its ability to evolve and develop. It is a life-threatening disease caused by parasites that are spread to people through the bites of infected Mosquitos. The most deadly of this disease lies in Cambodia. This deadly and drug-resistant disease is malaria. The story of drug-resistant malaria in Cambodia is significant because people in other countries could be affected and must be aware of the fact that it is becoming immune to the most powerful drugs used to fight it.
Several tests may be performed on patients to determine the cause of lymphatic damage and elephantiasis. A definitive diagnosis of lymphatic filariasis is done through the identification of the microfilariae in blood. Samples of blood are taken at night. Other test used for diagnosis is immunodiagnostic test; it can identify the cause of the symptoms based on the detection of antigens of Wuchereria bancrofti. This test is highly specific and sensitive, blood samples do not have to be taken at night (Seppa
Plasmodium Falciparum is the causative parasite of malignant malaria, it is the most deadly strain of the malaria viruses. P. Falciparum is a eukaryotic protozoan parasite that is spread through vector transmission using mosquitoes. The Anopheles mosquito family accounts for the majority of transmission because of their tendency to target humans (WHO, 2014). Malaria accounts for approximately five hundred thousand deaths each year in environments such as sub-Saharan Africa and other temperate areas where the life cycle of the mosquito is longer allowing the parasite to develop properly (WHO, 2014). Malaria usually infects children in these areas but also commonly spreads to travellers to these areas.
This disgusting worm parasite is spread by flies and mosquitoes. The adult worm spreads its larvae throughout the host’s lymphatic system and causes the lymph nodes to become clogged up. This also makes the tissue in the host’s body to swell up and create massive muscle deformations, otherwise known as elephantiasis. The elephantiasis mainly affects the legs and genitals. The disease also affects the eyes but that can be easily detected through close inspection but it commonly causes river blindness in the host. It’s been estimated that the parasite is one of the leading causes of blindness throughout the world.
On average there are around 300-500 million people who become infected with malaria every year, with most of the cases occurring in sub-Saharan Africa. (in text refernce). Other areas which are affected by malaria include- Asia, Latin America and some parts of Europe.
For several years, I have had an interest in virology and the spread and characteristics of various infectious diseases. Though it makes sense not to possibly induce a state of panic by informing individuals of illnesses that are not native to the area they live in and that they are not likely to contract, I have always liked to remain informed out of my own curiosity and interest. Thus, I have decided to write about malaria.
Malaria is a common disease in a hot tropical area and it affects about 300 million people worldwide. There are four types of parasites that cause malaria in humans. Among the types of species Plasmodium falciparum is most common in Africa region and it can cause deadly form of disease. The Plasmodium vivax which is the second type of species is not life-threatening form of malaria. Plasmodium ovale also causes malaria. The system malaria affect most is the immune system. Malaria undergoes a complex life cycle, which involves two separate asexual reproductive stages in the vertebrate host which include humans and sexual reproduction as well as multiplication in the insect vector of all human.
The way this disease is diagnosed is through the laboratory methods. The diagnosis is found on by looking at fluid or tissues by microscopy. T. b. rhodesiense is much more intense than T. b. gambiense, therefore you can find T. b. rhodesiense faster and easier, because its takes over more of the body than T. b. gambiense does. You can find T. b. rhodesiense in the blood, lymph node fluid or fluid, or a biopsy of chancre. As for T. b. gambiense you cannot find it in the blood easily, therefor is harder to diagnose. After diagnosis all patients with African sleeping sickness must have their cerebrospinal fluid examined to make sure there CNS is not in any danger because of the parasitic
Malaria is a disease that is caused by parasites. It is transferred from one person to another by the infected female Anopheles mosquito. Malaria has been a serious health problem nowadays. WHO has provided the information that approximately 660,000 people died from malaria globally during 2010. Also, after estimating, there are 219 million cases of malaria infection in 2010 worldwide. In sub-Saharan Africa, being one the country that has the high rate of HIV, AIDS, malaria, and tuberculosis, had 90% of the people that...

One of the current major concerns in the world is the outbreak of Ebola. Ebola is a infectious disease that comes from the Ebola virus and it can cause death if the patient is left untreated. The disease can be managed with treatment of the patient, however. Ebola is a disease that is a major concern in the Subsaharan African Realm, and in the North American Realm,but it is beginning to be dealt with sufficiently in the Northern American Realm.
Malaria (also called biduoterian fever, blackwater fever, falciparum malaria, plasmodium, Quartan malaria, and tertian malaria) is one of the most infectious and most common diseases in the world. This serious, sometimes-fatal disease is caused by a parasite that is carried by a certain species of mosquito called the Anopheles. It claims more lives every year than any other transmissible disease except tuberculosis. Every year, five hundred million adults and children (around nine percent of the world’s population) contract the disease and of these, one hundred million people die. Children are more susceptible to the disease than adults, and in Africa, where ninety percent of the world’s cases occur and where eighty percent of the cases are treated at home, one in twenty children die of the disease before they reach the age of five. Pregnant women are also more vulnerable to disease and in certain parts of Africa, they are four times as likely to contract the disease and only half as likely to survive it.
Why is it not possible nowadays to diagnose malaria with a set of signs and symptoms?The patient has been coughing for the last two weeks, lost 5 kilograms in weight, and whenever he coughs, very thick sputum in produced. Furthermore, the patient has been having chest pains, fever, sweating especially at night and loss of appetite (Harries, Maher, & Graham, 2004, p. 50). The sputum that is produced on coughing is not thick and is yellow in color (Warrell, Cox, & Firth, 2005, p. 560).
