Malaria Diagnosis, Treatment & Cost

✅Diagnostic Test for Malaria

Malaria diagnostic tests detect Plasmodium parasites in blood and identify the species causing the infection. To identify malaria, the following tests may be recommended:

• Laboratory diagnosis of malaria
• Supporting malaria blood test
  
  

Laboratory diagnosis of malaria

• Blood collection and preparation
• Sample type
• Slide preparation(malaria slide test/smear test)
• Thick smear
• Thin smear
• Staining
• Microscopy (gold standard)/Malaria parasite test
• Rapid diagnostic tests (RDTs)/Malaria antigen tests
• Molecular tests (PCR)
  
  

Blood collection and preparation
A sterile lancet is usually used to collect blood for malaria microscopy by pricking the finger (capillary blood). However, venous blood collected in Ethylenediaminetetraacetic acid (EDTA)tubes can also be used. The blood sample should be used to prepare smears immediately after collection, because delays may alter the shape (morphology) and colour (staining characteristics) of the parasites. Before making the smear for microscopic examination, it is important to label the slides correctly and use aseptic techniques.

Sample type
The best sample for diagnosing malaria is fresh whole blood, which is best taken from a finger-stick capillary sample or from venous blood with an anticoagulant (EDTA). This blood is used to make two thick and two thin blood smears on glass slides so that Plasmodium parasites can be seen under a microscope. To keep the parasite's integrity (how well the parasite functions in its relationship with the host), the smear should be made within a few hours of collecting the sample.

Slide preparation(malaria slide test/smear test)

Thick smear: For the thick smear method, 2–3 drops of blood are put on a clean slide in a small circle and left to dry. When slide-stained, red blood cells break down, which concentrates the parasites. This makes the method more sensitive for detecting malaria infection. But because the cells are broken down, it is harder to see the parasite's shape and identify its species.

Thin smear: A small drop of blood is spread across the slide, then another slide is placed on top to make a thin film with a feathered edge. The smear is dried in the air, fixed with methanol, and then stained, usually with Giemsa stain. Thin smears make it easy to see red blood cells and the shapes of parasites, which is important for identifying the Plasmodium species and estimating the number of parasites.

Staining: Staining enables clear visualization of malaria parasites in blood smears. Giemsa stain is often used to color blood smears, making it easy to distinguish the parasites from red blood cells. Correct staining makes it easier to visualize parasite life cycle stages such as trophozoites, schizonts, and gametocytes. This step is very important before the subsequent microscopic examination.

Microscopy (gold standard)/Malaria parasite test: The standard method for detecting malaria is to examine thick and thin-stained blood smears under a microscope. Thick smears make the test more sensitive by concentrating the parasites, while thin smears help determine the Plasmodium species type and the number of parasites present. Microscopy helps clinicians see parasites directly, which helps them to decide treatment. Results should be available rapidly for the timely management of malaria.

Rapid diagnostic tests (RDTs)/Malaria antigen tests: Using an immunochromatographic dipstick or cassette, rapid diagnostic tests for malaria detect certain antigens in a person's blood. These tests give results in about 15 minutes and are helpful when microscopy is not available. But RDTs might not detect infections with low malaria parasite levels, so it's best to confirm positive or negative results with microscopy.

Molecular tests (PCR): Polymerase chain reaction (PCR) can help find parasite DNA in blood samples. It is more accurate and sensitive than microscopy and is mostly used to confirm the type of malaria or find mixed infections after the initial diagnosis. However, PCR isn't used very often for routine acute diagnosis because it can take longer to get test results.

Supporting malaria blood test

When initial clinical findings suggest malaria, supporting diagnostic tests help confirm the infection and identify the specific malaria Plasmodium species. A general physician may perform the following tests:

• Complete blood count (CBC)
• Serum glucose and lactate
• Renal function test (RFT)
• Liver function test (LFT)
• Follow-up testing

Complete blood count (CBC)

A CBC is a supportive laboratory test used in suspected cases of malaria. CBC tests often show that people with malaria have anaemia (low haemoglobin) and thrombocytopenia (low platelet counts). Leukocyte (a type of white blood cell) counts are typically normal or marginally reduced. These results support the diagnosis but are not specific for malaria. Therefore, tests such as microscopy or rapid diagnostic tests are essential for confirming malaria.

Serum glucose and lactate

Measuring blood glucose and serum lactate levels can help determine malaria-induced metabolic complications. Severe malaria can cause hypoglycemia (reduced serum glucose levels <40 mg/dL or 2.2 mmol/L) due to increased glucose uptake by malarial parasites or due to antimalarial therapy. Raised serum lactate levels (>5 mmol/L) indicate metabolic acidosis and poor tissue perfusion. These are important signs of severe malaria and a higher risk of death.

Renal function test (RFT)

Serum creatinine and blood urea nitrogen (BUN) levels are examples of renal function tests (RFTs) that can show if malaria is affecting the kidneys. In severe malaria, serum creatinine levels > 3 mg/dL (265 µmol/L) or elevated blood urea levels signify compromised kidney function because of dehydration, hemolysis (the breakdown of red blood cells), or microvascular obstruction, which can cause acute kidney injury. These results help determine disease severity and treatment guidance.

Liver function test (LFT)

Liver function tests measure bilirubin and liver enzymes (AST and ALT) in people with malaria. Elevated bilirubin(hyperbilirubinemia) may result from hemolysis of infected red blood cells or liver dysfunction, and jaundice with bilirubin levels exceeding 3 mg/dL is considered an indicator of severe malaria associated with parasitemia. So, LFTs can help determine disease severity and the extent of liver involvement.

Follow-up testingIt is recommended to do follow-up tests to monitor treatment response and confirm clearance of parasites from the blood. It is suggested to repeat blood smears every 12–24 hours until parasitemia (a parasitic infection in the blood) is no longer present. Continuous monitoring helps in the identification of treatment effectiveness, prevents complications, and detects treatment failures. A follow-up evaluation is very important for people with severe malaria.

Interpretation of results (malaria test report)

Detection of Plasmodium parasites on a stained thick or thin blood smear confirms malaria. Microscopy can identify parasite species and determine parasite density(number). A negative smear makes malaria unlikely, but clinical suspicion remains strong; blood smears should be done every 12 to 24 hours for up to three sets before ruling out malaria.

Management of malaria involves early diagnosis and the use of effective malaria treatment drugs to kill the parasite and prevent complications. The selection of therapy depends on the Plasmodium species, the severity of the disease, and the local patterns of drug resistance.

The following are the steps involved in malaria treatment guidelines:

Selection of antimalarial medication

Uncomplicated P. falciparum and uncomplicated P. knowlesi: For uncomplicated Plasmodium falciparum malaria treatment, artemisinin-based combination therapy (ACT) is used. These drugs quickly eliminate parasites and reduce the risk of drug resistance. Quinoline-based antimalarial therapy doesn't work against or is resistant to P. falciparum in most areas, so ACT therapy is the first choice for malaria treatment, and chloroquine or ACT is usually used to treat P. knowlesi infections because there have been no reports of widespread resistance. It is important to treat and monitor these species immediately, as they can deteriorate rapidly.

Uncomplicated P. vivax and P. ovale

Treatment of uncomplicated malaria, Plasmodium vivax and Plasmodium ovale, involves two stages:

• Blood-stage treatment
• Liver-stage treatment (radical cure)
  
  

Blood-stage treatment: Quinoline-based antimalarial therapy or an artemisinin-based combination therapy (ACT) is used to treat the acute blood-stage of malaria, depending on the level of drug resistance in the area. Chloroquine is effective and commonly used to kill circulating blood parasites in areas where it is sensitive. If resistance is suspected or quinoline-based antimalarial therapy is unavailable, ACT can be used as an alternative to rapidly clear the infection.

Liver-stage (radical cure): P. vivax and P. ovale can make dormant liver stages called hypnozoites. These can cause a relapse weeks or m onths after the first infection. Consequently, following blood-stage treatment, patients necessitate 8-aminoquinoline antimalarial drugs (primaquine or tafenoquine) to eliminate these hepatic forms and attain a radical cure in malaria (treating the disease from its root cause). It is advised to test glucose-6-phosphate dehydrogenase (G6PD) deficiency prior to administering these medications, as they may induce hemolytic anaemia (decreased red blood cell (RBC) count because of excessive destruction of RBCs) in affected individuals.

Special population

When treating malaria in special groups like pregnant women, infants, young children, and people with other comorbid conditions, it is important to carefully select malaria drugs and doses to make sure they are both safe and effective.

• Treatment of malaria in pregnancy
• Treatment of malaria in children

Treatment of malaria in pregnancy: Malaria in pregnancy should receive prompt treatment because infection can lead to severe maternal illness, miscarriage, premature delivery, and low-birth-weight infants. In the treatment of uncomplicated malaria, recommended drugs depend on the trimester; quinine with lincosamide(clindamycin)is commonly used in the first trimester, while artemisinin-based combination therapy (ACT) can be used in the second and third trimesters, and 8-aminoquinoline antimalarial drugs (primaquine or tafenoquine) are not recommended during pregnancy because of potential fetal toxicity.

Treatment of malaria in children: Children, particularly those under five years of age, are at significant risk of severe malaria and require weight-based dosing of antimalarial medications. Artemisinin-based combination therapy (ACT) is the first-line treatment for uncomplicated malaria in children. Intravenous or intramuscular artesunate is the best treatment for severe malaria. If injectable therapy isn't available immediately, rectal artesunate can be used as a pre-referral treatment in community settings. It is important to carefully adjust the dose of the 8-aminoquinoline antimalarial drug (primaquine) for infants and young children based on their weight, and it is not safe for very young infants to take this drug.

Management of severe malaria

Management of severe malaria requires immediate identification and administration of parenteral/intravenous antimalarial drugs, complemented by supportive care to prevent life-threatening complications and reduce death rates.

• Parenteral therapy
• Supportive treatment for malaria
• Switching to oral drugs

Parenteral therapy: Patients with severe malaria should get parenteral antimalarial treatment immediately, preferably via intravenous or intramuscular route for at least 24 hours to quickly decrease the frequency of parasites and prevent complications. If ACT therapy isn't available, parenteral quinine can be used as an alternative drug.

Supportive treatment for malaria: Severe malaria management requires comprehensive supportive care, including monitoring vital signs, coma scale, urine output, and serum glucose levels, in addition to managing complications such as hypoglycemia, anemia, seizures, cerebral malaria (Glasgow coma scale(GCS) <11 with parasitemia; manage with airway protection, anticonvulsants, and avoid routine invasive intracranial pressure(ICP) monitoring unless refractory)and fluid imbalance. Continuous clinical monitoring, ideally in an ICU environment, helps reduce mortality and organ failure.

Transition to oral drugs: After at least 24 hours of parenteral therapy and once the patient can tolerate oral medication, the patient should be transitioned to oral artemisinin-based combination therapy (ACT) to ensure complete parasite clearance. This step prevents recurrence of malaria and ensures a complete cure.

Monitoring and Follow-Up

Monitoring and follow-up of patients with malaria are crucial for evaluating treatment efficacy, promptly identifying complications, and confirming complete parasite eradication following antimalarial therapy.

• Parasite clearance
• Glucose-6-phosphate dehydrogenase (G6PD) screening
• Adherence

Parasite clearance: Follow-up blood smear microscopy is used to assess parasite density and confirm that antimalarial therapy has killed the parasites in the blood. Follow-up exams are usually done on certain days (like day 3, 7, 14, and 28) to monitor treatment response or malaria relapses.

Glucose-6-phosphate dehydrogenase(G6PD) screening: Before prescribing an aminoquinoline antimalarial drug, such as primaquine or tafenoquine, to treat Plasmodium vivax malaria, it is recommended to test for glucose-6-phosphate dehydrogenase (G6PD) deficiency. This testing is necessary because patients with G6PD deficiency may experience severe hemolytic anemia when administered these medications.

Adherence: Patients should be advised to complete the full course of antimalarial treatment and to attend all scheduled follow-up visits for evaluation. Proper adherence helps in complete parasite clearance, reduces malaria relapses, and allows clinicians to monitor the patient's progress or treatment failure during follow-up.

Non-pharmacological management of malaria

The following are some of the malaria nonpharmacological treatments, which include:

• Mosquito avoidance
• Insecticide-treated nets (ITNs)
• Insect repellents
• Protective clothing
• Environmental management
• Fever management
• Hydration and nutrition
• Dietary support
• Rest

Mosquito avoidance: Preventing mosquito bites is important because malaria is transmitted through infected Anopheles mosquitoes. Limiting exposure to mosquitoes, especially during peak hours of biting and taking personal protective measures reduces the risk of illness.

Insecticide-treated nets (INTs): Sleeping under insecticide-treated nets is advised because they keep mosquitoes away and help protect them from bites. These nets greatly reduce the spread of malaria and protect individuals and communities in endemic areas.

Insect repellants: Topical insect repellents applied to exposed skin protect individuals by repelling mosquitoes, thereby reducing bites. These repellents are suggested as alternative protective measures against malaria-carrying insects (malaria vectors).

Protective clothing: Wearing protective clothing, such as long pants, long-sleeved shirts and clothing that covers most of the body, can help protect individuals from mosquito bites by reducing direct contact between the mosquito vector and human skin.

Environmental management: The main goal is to reduce mosquito breeding sites by eliminating standing water, improving drainage, and monitoring bodies of water. These steps reduce the mosquito population, thereby reducing the spread of malaria.

Fever management: People with a fever should seek medical help promptly to detect malaria early and avoid complications. Community health programs also stress the importance of early reporting and treating cases of fever.

Hydration and nutrition: Drinking enough fluids and maintaining proper nutrition can help maintain body strength and prevent dehydration during fever, such as that caused by malaria. Supportive care, such as fluids and nutritional support, helps individuals speed recovery.

Dietary support: Eating a balanced diet helps maintain energy levels and supports the immune system during illness. Patients with malaria should get proper nutrition as part of their supportive care.

Rest: Malaria patients should get plenty of rest to conserve energy and help their bodies heal from the infection. Adequate rest also helps reduce fatigue(tiredness) associated with fever and other systemic illnesses.

✅Malaria Prognosis

The prognosis of malaria mainly depends upon early diagnosis, the severity of the infection and the initiation of immediate therapy. Patients with uncomplicated malaria typically achieve full recovery when promptly treated with prescribed antimalarial medications. However, getting infected with Plasmodium falciparum can rapidly cause serious illness and may be deadly if treatment is not started early. Severe malaria can cause complications like cerebral malaria (infection affecting the brain), severe anaemia, or organ failure, which can cause death. Early diagnosis and the appropriate treatment can greatly lower the risk of death and improve clinical outcomes.

Frequently Asked Questions (FAQs) on Malaria

How to cure malaria?

Malaria is an infectious disease that is curable with prescription antimalarial drugs, prescribed by a physician upon early diagnosis and initiation of malaria treatment, and it depends on the type of malaria parasite, the severity of symptoms, the patient's age, pregnancy, and location of origin of infection, because of drug resistance patterns.

How to test for malaria?

Malaria is diagnosed through blood tests that detect parasites or antigens. The most common tests are Rapid Diagnostic Tests (RDTs), which give results in 15 to 20 minutes, and Microscopic Blood Smears, which are the best way to determine the type of malaria and its severity. Testing should be done when someone has a fever, either with a finger-prick RDT or a blood film in a lab.

How to identify malaria mosquitoes?

The female mosquitoes of the genus Anopheles spread malaria. These mosquitoes can be identified apart by their palps, which are as long as their proboscis (long, flexible, tube-like organ used for feeding or sucking), and by the black-and-white scale patterns on their wings. Anopheles mosquitoes rest with their abdomens raised at an angle to the surface, unlike other mosquitoes. Only female mosquitoes bite individuals and spread malaria parasites.

Is malaria a protozoan disease?

Yes, a protozoan parasite from the genus Plasmodium causes malaria. Bacteria and viruses do not cause it. A bite from an infected female Anopheles mosquito can spread these tiny, single-celled organisms to people, and the parasites can enter the liver and red blood cells, thereby causing infection.

What happens in malaria?

Malaria is a serious parasitic disease that is spread by the bites of female Anopheles mosquitoes. It causes high fever, chills, headaches, and anemia 10 to 15 days after infection. Parasites grow in the liver and then destroy red blood cells. If this isn't treated, it can cause organ failure, coma, or death. It is very important to start antimalarial treatment promptly.

What is the infective stage of the malaria parasite?

The sporozoite is the form of the malaria parasite (Plasmodium species) that is transmitted from a mosquito to a person. These slender, moving organisms are injected into the human bloodstream through the saliva of an infected female Anopheles mosquito during a blood meal.

Can malaria increase blood pressure?

Yes, malaria can raise blood pressure (BP) by activating the renin-angiotensin-aldosterone system (RAAS), which increases BP by sodium and water retention, inflammation, and endothelial dysfunction (impaired function of the inner lining cells of blood vessels). Acute malaria is associated with high fever and elevated systolic BP. Prolonged recurrence of infections can cause heart problems and hypertension (high blood pressure).

Why only the female Anopheles mosquito causes malaria?

Only female Anopheles mosquitoes can spread malaria because they need blood meals to feed their eggs. Males, on the other hand, only eat plant nectar. The Plasmodium parasite needs this specific feeding behavior on blood meals to move between human hosts and to infect the female's salivary glands during blood digestion.

Can malaria be transmitted from mother to child during pregnancy?

Which doctor treats malaria?
