Why did the malaria eradication campaign fail?
An eradication campaign was started in the 1950s, but it failed globally because of problems including the resistance of mosquitoes to insecticides used to kill them, the resistance of malaria parasites to drugs used to treat them, and administrative issues. In addition, the eradication campaign never involved most of Africa, where malaria is the most common.

Which type of malaria is most likely to result in severe infections and if not promptly treated, may lead to death answer?
knowlesi, a type of malaria that naturally infects macaques in Southeast Asia, also infects humans, causing malaria that is transmitted from animal to human (“zoonotic” malaria).

Chloroquine phosphate. Chloroquine is the preferred treatment for any parasite that is sensitive to the drug. But in many parts of the world, parasites are resistant to chloroquine, and the drug is no longer an effective treatment.
What are the symptoms of malaria?
Initial symptoms of malaria may include shaking chills, high fevers, sweating, headaches, nausea and vomiting, anemia, and/or diarrhea. Diagnostic tests include microscopic examination of the blood for the presence of parasites, serology, PCR testing, and other tests that determine if the parasite is resistant to certain drugs.

Why is it important to understand the duration of antigen persistence?
Understanding the duration of antigen persistence is critical for correctly interpreting RDTs from recently-treated individuals, and reduces the probability of clinicians mismanaging non-malarial fevers contribu ting to ACT resistance .
Why is parasite based diagnosis difficult?
This was challenging for most local clinics because a parasite-based diagnosis relies primarily on observing blood samples under a microscope; a time consuming process that uses expensive equipment and training, which is neither readily available nor cost-effective for a small-scale health clinic.

Malaria is one of the major causes of preventable death in the world today. It affects more than 500 million people worldwide and causes 1 to 2 million deaths every year. It is a tropical disease.
What is the purpose of blood smears for malaria?
Blood tests will be done to determine whether malaria has affected your levels of red blood cells and platelets, the ability of your blood to clot, your blood chemistry, and your liver and kidney function.
What causes the most deaths from malaria?
Most deaths from malaria are caused by P. falciparum, which causes severe disease. Before P. falciparum malaria causes a red blood cell to burst, it can make the surface of the cell stick to other cells like it. This causes the blood to clot within small blood vessels, which can severely damage organs.
When should malaria treatment be initiated?
Ideally malaria treatment should not be initiated until the diagnosis has been established by laboratory testing. “Presumptive treatment”, i.e., without prior laboratory confirmation, should be reserved for extreme circumstances, such as strong clinical suspicion of severe disease in a setting where prompt laboratory diagnosis is not available.
How often should you do a malaria smear?
In infections with P. falciparum, P. knowlesi, or suspected chloroquine-resistant P. vivax, blood smears should be repeated every 12–24 hours to monitor parasitological response to treatment, i.e., decrease in parasite density. It is recommended to document a negative malaria smear after treatment, but this could be done as an outpatient depending on clinical and parasitological response and the judgement of the treating clinician. Note that gametocytes, the sexual stage of the parasite, are not targeted by most of the antimalarials and should not be counted in assessing parasite density.
What is the best treatment for malaria?
After the initial course of IV artesunate is completed, if parasite density is ≤ 1% (assessed on a blood smear collected 4 hours after the last dose of IV artesunate) and patient can tolerate oral treatment, a full treatment course with a follow-on regimen must be administered. Artemether-lumefantrine (Coartem™) is the preferred follow-on treatment but adequate alternatives are atovaquone-proguanil (Malarone™), quinine plus doxycycline or clindamycin, or mefloquine. Because of a risk of severe neuropsychiatric adverse events at treatment doses, mefloquine should only be used if other options are not available. If the patient received oral treatment prior to receiving IV artesunate, the same medication can be used as follow-on treatment, but a full regimen is required. As for any malaria treatment, the regimen selection should not include the medication used for chemoprophylaxis.
What is the best antimalarial for interim treatment?
The preferred antimalarial for interim oral treatment is artemether-lumefantrine (Coartem™) because of its fast onset of action. Other oral options include atovaquone-proguanil (Malarone™), quinine, and mefloquine. Intravenous or oral clindamycin and tetracyclines, such as doxycycline, are not adequate for interim treatment. These drugs are slow-acting antimalarials that would not take effect until well after 24 hours, and they are not effective antimalarials for treatment of severe malaria when used alone. As for any malaria treatment, the interim regimen should not include the medication used for chemoprophylaxis if possible.
How to determine malaria parasite density?
This can be done by looking at a monolayer of red blood cells (RBCs) on the thin smear using the oil immersion objective at 100x. The slide should be examined where the RBCs are more or less touching (approximately 400 RBCs per field). The parasite density can then be estimated from the percentage of infected RBCs, after counting 500 to 2,000 RBCs. Gametocytes, the sexual stage of the parasite, are not responsible for clinical symptoms and should not be counted when determining parasite density. More information on diagnostic procedures for malaria can be found on CDC’s DPDx website.
How often should you have a blood smear for malaria?
However, because non-immune individuals may be symptomatic at very low parasite densities which may be initially undetectable, blood smears should be repeated every 12–24 hours for a total of three sets before the diagnosis of malaria can be ruled out.
How long does it take for a blood smear to be read?
Thin smears aid in parasite species identification and quantification. Blood smears need to be done and read as soon as possible, within 24 hours of patient presentation; qualified personnel who can perform these tasks should always be on-call. A negative blood smear makes the diagnosis of malaria unlikely.
