Malaria is a mosquito-borne disease caused by a parasite. People with malaria often experience fever, chills, and flu-like illness. Left untreated, they may develop severe complications and die.

Malaria Case Study

Hippocrates, the father of medicine, is generally credited with the first description of the clinical symptoms in 500 bc, more than 2000 years before the parasite was ) and exhibit a heteroxenous life cycle involving a vertebrate host and an arthropod vector. The malarial paroxysm corresponds to the rupture of the infected erythrocytes and the release of merozoites (figure above). A large proportion of the populations in western africa are duffy negative, thus accounting for the low levels of in west africa.

As discussed for the , antigens or toxins released by the infected erythrocyte could stimulate the production of proinflammatory cytokines. Some questions have been raised in regards to the economic sustainability of bednet programs. During the strategy development process, who consulted all affected countries through a series of 7 regional consultations.

In addition, there is minimal lymphocyte infiltration or inflammation associated with the blocked capillaries. In constrast to the usually highly conserved nature of receptor-ligand interactions, ) gene family with 40-50 different genes. Malaria is a chronic disease which has a tendency to relapse or recrudesce (see the most common way to obtain malaria is through the natural transmission by mosquitoes (see ).

Persons living in highly endemic areas usually exhibit a high level of immunity and tolerate the infection well. The parasite is injected with the saliva during mosquito feeding and first undergoes a round of merogony in the liver followed by multiple rounds of merogony in the erythrocytes. The blood-stage parasites within a host usually undergo a synchronous schizogony.

In addition, certain genetic diseases and polymorphisms have been associated with decrease infection or disease (see the potential of the mosquito to serve as a vector depends on the ability to support sporogony, mosquito abundance, and contact with humans, which are all influenced by climatic and ecological factors (table). However, at the morphological level this is much less dramatic than the exflagellation exhibited by the microgametocytes. Identifying and treating infected persons, especially asymptomatic individuals, will reduce the size of the parasite reservoir within the human population and can lower transmission rates.

Severe, or complicated, falciparum malaria is a serious disease with a high mortality rate and must be regarded as life threatening, and thus requires urgent treatment. Patients infected with rarely causes complications or results in death. Fatigue, dizziness, anorexia, myalgia, and nausea will often be associated with the hot stage. Wongsrichanalai c, pickard al, wernsdorfer wh and meshnick sr (2002) epidemiology of drug-resistant malaria. The fever paroxysm corresponds to the period of infected erythrocyte rupture and merozoite invasion.

CDC - Malaria - About Malaria - FAQs
Malaria is a serious and sometimes fatal disease caused by a parasite that commonly infects a certain type of mosquito which feeds on humans. People who get malaria are typically very sick with high fevers, shaking chills, and flu-like illness. Four kinds
Malaria Case Study Some questions have been raised in regards to the economic sustainability of bednet programs. Chemoprophylaxis requires the use of non-toxic drugs since these drugs will be taken over extended periods of time. Biological control methods include the introduction of fish which eat the mosquito larvae or bacteria (eg, ) which excrete larval toxins, The blue line depicts the microscopic threshold (ie. The patient is exhausted and weak and will usually fall asleep. These merozoites invade new erythrocytes and initiate another round of schizogony. Malaria was previously more widespread in temperate areas including north america and europe. Side effects may include pruritus (i. Diagram representing the course of malaria infection. High levels of transmission may allow re-infection while drugs are at sub-therapeutic levels. Nitric oxide is known to affect neuronal function and through its vasodilator activity. The sporozoites enter the circulatory system and within 30-60 minutes will invade a liver cell.

    Wongsrichanalai c, pickard al, wernsdorfer wh and meshnick sr (2002) epidemiology of drug-resistant malaria. On occassion severe malaria involving multiple organs has also been noted in is the most benign in that the paroxysms tend to be mild and of short duration and relapses seldom occur more than one year after the initial infection. Different communities will experience a different malaria and consequently different control and treatment strategies may be necessary. Identifying and treating infected persons, especially asymptomatic individuals, will reduce the size of the parasite reservoir within the human population and can lower transmission rates. Late stage schizonts in which the individual merozoites become discernable are called.

    For example, previously semi-immune adults will often develop severe malaria upon returning to an endemic area after being in a non-endemic area for 1-2 years. Other links of interest choloroquine ( other 4-aminoquinolines), quinine, quinidine, mefloquine, halofantrine, antifolates (pyrimethamine, proquanil, sulfadoxine, dapsone), artemisinin derivatives (quinhaosu) primaquine, artemisinin derivatives, 4-aminoquinolines (limited?) fansidar (pyrimethamine sulfadoxine), maloprim (pyrimethamine dapsone), malarone (atovaquone proquanil) fast-acting blood schizontocides, which act upon the blood stage of the parasite, are used to treat acute infections and to quickly relieve the clinical symptoms. For example, in the united states quinine and quinidine are the approved drugs for severe malaria. The severity of the attack depends on the and the general health and nutritional status of the infected individual. Vertebrate hosts include reptiles, birds, rodents, monkeys and humans.

    Chloroquine resistant was not reported until 1989 in papua new guinea and is now found in several foci in southeast asia and perhaps south america. The use of mefloquine for malaria chemoprophylaxis is somewhat controversial. A modified protocol based on clinical outcome was introduced by who in 1996. The symptoms tend to correlate with increasing numbers of parasites. Oversight was provided by the malaria policy advisory committee. Chloroquine is generally the recommended treatment for patients with infections. G min-oo, p gros (2005) erythrocyte variants and the nature of their malaria protective effect. Upon awakening the patient usually feels well, other than being tired, and does not exhibit symptoms until the onset of the next paroxysm. R idro, ne jenkins, crjc newton (2005) pathogenesis, clinical features, and neurological outcome of cerebral malaria. For example, outdoor feeding mosquitoes are more likely to find a human blood meal in the early evening than those feeding late at night when most people are inside.

    The purpose of the study is to demonstrate the effectiveness and feasibility of community-based management of pneumonia and malaria by community health workers (CHWs) in a rural district of Zambia. Pneumonia and malaria are the two leading causes of morbi

    A shorter duration of sporogony increases the chances that the mosquito will transmit the infection within its lifespan. Thick blood smears are generally more sensitive for the detection of parasites, whereas thin smears are preferable for species identification. This sequestration provides several advantages for the parasite. In addition, some have raised concerns about the long-term benefits of bednets since they reduce exposure, but do not eliminate it. The sequestration hypothesis and cytokine theory for the pathophysiology of cerebral malaria are not mutually exclusive, and both phenomenon are likely to be involved.

    The behavior of the mosquito also needs to be considered in control activities. Mechanical transmission of infected blood will result in a shorter incubation period since there will be no liver stage. Some questions have been raised in regards to the economic sustainability of bednet programs. Such approaches include the reduction in mosquito breeding grounds (eg, environmental modification), target the larva stages with chemical or biological agents, and massive insecticide spraying for the adult mosquitoes. Cerebral malaria is characterized by an impaired consciousness (box).

    There is an increased activity of the reticuloendothelial system, particularly in the liver and spleen and thus their enlargement, as evidenced by macrophages with ingested infected and normal erythrocytes and hemozoin. In addition, the low oxygen tensions in the deep tissues may provide a better metabolic environment. Except for , the pathology associated with malaria tends to be benign. In addition, there is also a good correlation between animal species which express knobs and exhibit sequestration. The immune response could be directed at either the pre-erythrocytic or erythrocytic stages of the parasites life cycle.

    These paroxysms will exhibit periodicities of 48 hours for initially the periodicity of these paroxyms may be irregular as the broods of merozoites from different exoerythrocytic schizonts synchronize. Mdr1 appears to contribute to the degree of chloroquine resistance, but alone it is insufficient to confer resistance. Vaccines targeted against merozoites or the infected erythrocyte would lower parasitemia by interfering with merozoite invasion or increasing the elimination of infected erythrocytes. As in the case of treatment there is no standard recommendation and the choices for chemoprophylaxis are highly dependent upon the conditions associated with the travel and the indivdual person For Sale Malaria Case Study
