5 Malaria is an Important Contributor to Maternal Mortality in Endemic Countries
6 Malaria during pregnancy: bad news Each year, more than 30 million women in Africa become pregnant in malaria-endemic areas.Malaria during pregnancy in sub-Saharan Africa is estimated to account for:400,000 cases of severe anemia in pregnant women~ 35% of preventable low birth weight~ 5% of infant mortality75, ,000 infant deaths annually
7 Why Is Malaria in Pregnancy (MIP) Important? MIP effects on Women2-15% of maternal anemiaPossibly up to 10,000 maternal deaths annuallyPossible effects on pre-eclampsiaIncreased post-partum hemorrhageEach year, more than 30 million women in Africa become pregnant in malaria-endemic areas. In these areas, malaria accounts for significant morbidity in pregnant women. For example, it accounts for 2–15% of maternal anemia and 5–14% of low birth weight. Of those newborns born with “preventable” low birth weight, 30% are due to malaria. Malaria also accounts for between 3–5% of all newborn deaths.Source: WHO Afro 2004
8 Placental Malaria in African Women: the First Pregnancy Is Most Dangerous This slide summarizes results from studies in eight countries in Africa. In virtually all the countries listed, primigravid women had a higher prevalence of placental parasitemia when compared to multigravid women.Placental malaria deprives the fetus of nutrients
9 MIP effects on fetus/child 13-70% intrauterine growth retardationAs high as 20% of low birth weight newborns30% of “preventable” low birth weight newborns8-36% of preterm births~5% congenital malaria in newborns3-5% of newborn deaths, 3-8% of infant deathsMiscarriage and stillbirth

As shown, newborns with malaria parasites in their placenta (represented by the left bar in each cluster) had a higher risk of being born with a low birth weight when compared with newborns with no malaria parasites in their placenta (represented by the right bar in each cluster). This is true regardless of the birth order, which could be the first, the second or later pregnancy.FirstPregnancySecondPregnancyThree or morepregnanciesSource: Steketee 2001: Malawi
11 Characteristics of Malaria Transmission Stable AreasYear-round transmission e.g. NigeriaPeople receive frequent infective mosquito bites each monthLevels of acquired immunity are high (pregnant women are semi-immune to malaria)Low peripheral parasitemiaHeavy placental infectionUnstable AreasSeasonal or epidemic transmission e.g. South AfricaPeople are infrequently exposed to malariaLevels of acquired immunity are low (pregnant women are not immune)Heavy peripheral parasitemiaLow or undetectable placental infectionThe intensity of malaria transmission in an area determines the effect of malaria on pregnancy. In areas of stable transmission, malaria is frequently transmitted by mosquitoes from one person to another resulting in high levels of acquired immunity. Pregnant women in these areas are semi-immune to malaria and have a low prevalence of peripheral parasitemia but a high prevalence of placental infection.On the other hand, in areas of unstable transmission, malaria is infrequently transmitted from one person to another. Therefore, pregnant women in these areas have low levels of acquired immunity with heavy peripheral parasitemia and low or undetectable levels of placental infection.
12 Effect of MIP in Stable Transmission Areas Acquired immunity – high1st & 2nd pregnancies at greatest riskPrevention essential (as most women are not symptomatic)Plasmodium falciparum malariaAsymptomatic InfectionPlacental SequestrationAltered Placental IntegrityReduced Nutrient and Oxygen TransportThis slide summarizes the sequence of events in stable areas of malaria transmission. In these areas, women have a high level of acquired immunity to Plasmodium falciparum malaria and are often asymptomatic due to low peripheral parasitemia. Pregnancy naturally lowers cell-mediated immunity and causes immunosuppression. In areas of stable transmission, the placenta is a protected site for parasite sequestration and growth. Its effect during pregnancy appears to be “parity-specific”. During the first malaria-exposed pregnancy (that is, in primigravida), local immunity to malaria develops in the placenta. This immunity has no effect in the first pregnancy but is retained in the uterus and increases cumulatively in subsequent pregnancies. This is why women in their first and second pregnancies are more affected by malaria than women in subsequent pregnancies.The malaria parasites in the placenta damage placental integrity and interfere with the ability of the placenta to transport nutrients and oxygen to the fetus, thereby causing intrauterine growth retardation, a factor for delivery of low birth weight newborns. A low birth weight newborn is defined as one that is born weighing 2500 grams or less. Another pathway to low birth weight is severe maternal anemia which is also caused by the malaria infection. In general, low birth weight babies have a higher risk of dying in infancy.AnemiaLow Birth Weight (IUGR)Risk of Newborn MortalitySource: WHO 2002.
13 Effect of MIP Unstable Transmission Areas Acquired immunity – lowAll pregnancies affected equallyPrompt diagnosis and treatment needed in addition to preventionAcquired Immunity – LowClinical IllnessSevere DiseaseRisk to MotherRisk to FetusWomen in these areas have lower levels of acquired immunity. Therefore, they have an increased frequency and severity of malaria and anemia. Delayed recognition and inappropriate treatment may lead to a progression to severe disease, which has serious consequences for both the mother and the fetus. This effect is seen in virtually all pregnancies, irrespective of parity.Source: WHO, 2002
14 Interventions to Control Malaria in Pregnancy WHO’s 3-pronged approach
15 Three Main Control Tools IPTp = Intermittent preventive treatment in pregnancyITNs = Use of insecticide-treated nets, including long lasting insecticide treated nets (LLINS)Case management of malaria diseaseDiagnosis with Rapid Tests, MicroscopyAppropriate antimalarial drug for treatmentIndoor Residual Spraying not specific to MIP, but where offered should be mentioned in health education to women
17 Intermittent Preventive Treatment in Pregnancy IPTp is an approach for effectively preventing and controlling malaria during pregnancy thatIs based on an assumption that every pregnant woman in a malaria-endemic area is infected with malaria, andRecommends that every pregnant women receive at least two treatment doses of an effective antimalarial drug as a preventive measureSulfadoxine-pyrimethamine (SP) currently considered the most effective drug for IPTpThe second component of the strategic framework for malaria control during pregnancy is “intermittent preventive treatment”. Intermittent preventive treatment is an intervention for effectively preventing and controlling malaria during pregnancy. It is based on the assumption that every pregnant woman living in an area of stable or unstable malaria transmission has malaria parasites in the blood or in the placenta, and therefore, should be treated to minimize its effects on the mother and her fetus. Intermittent preventive treatment with SP is currently the most effective approach for the use of antimalarial drugs during pregnancy and is particularly attractive for use in areas with a high level of chloroquine resistance.
18 IPTp with Sulfadoxine-Pyrimethamine SP is a combination of two different drugs. Each tablet of SP contains:500 mg of sulfadoxine, and25 mg of pyrimethamineA single dose consists of three tablets taken at once, preferably under direct observation of the healthcare providerFansidar is the most common brand name. Others include Falcidin, Laridox, Maladox, Orodar, MaloxineSP is generally more effective than chloroquine which is no longer effective in most countries because of parasite resistanceSulfadoxine-pyrimethamine is the drug of choice in many countries for intermittent preventive treatment of malaria. SP, as it is often called, is a combination of two drugs. Each tablet contains 500 mg of sulfadoxine and 25 mg of pyrimethamine. A single dose consists of three tablets taken at once, preferably under direct observation by the healthcare provider. Fansidar is the most common brand of SP, but there are other brands such as Falcidin, Laridox and Maladox. SP is generally more effective than chloroquine due to the increasing prevalence of chloroquine resistance in many parts of Africa. Note that chloroquine is no longer for case management or prophylaxis in Africa. SP is reserved for IPTp only, not for treatment in the general population.
19 Effect of IPTp with SPCase management alone does not reduce effects of malaria in pregnancy as well as IPTpNot all women with malaria parasites have symptoms, and therefore would not receive treatment if we relied solely on case managementIPTp produced better outcomes in terms of reducingMaternal and placental parasitemiaLow birth weightIPTp is as effective as case management in terms of improving hemoglobin levelsWhen used for IPTp, SP also reduces the effects of malaria better than case management alone. This is important since not all women with malaria parasites have symptoms and therefore would not receive treatment if case management was implemented without IPTp.An important study from Kenya presents evidence supporting the use of IPTp with SP. In the study three groups of pregnant women were analyzed: women who had case management for malaria illness, women who were protected by the two-dose SP regimen, and women protected by a monthly SP regimen. The groups protected with the two-dose or monthly SP regimens had higher mean blood hemoglobin levels than those in the malaria group. Also, the groups protected with SP had lower incidence rates of maternal parasitemia and placental parasitemia compared to women seen with malaria illness.The incidence of low birth weight newborns among those who were protected with SP (8%) was also lower than among those not protected with SP (which was 14%). The conclusion is that intermittent preventive treatment offers some protection from the adverse consequences of malaria during pregnancy.Compared with case management, studies have also shown both IPTp and case management to be equally effective in improving hemoglobin levels.
20 Fetal Growth Velocity Fetal growth velocity Weeks of gestation 10 16 LastmonthWe give SP as IPTp at a particular time during pregnancy. The dotted line in this slide represents fetal growth velocity during pregnancy. Fetal growth velocity is relatively slow in the first half of pregnancy but increases rapidly in the second half of pregnancy. Because the presence of parasites in the placenta interferes with the transfer of nutrients to the fetus, it is important to ensure that the fetus’s placenta is free of malaria parasites when fetal growth velocity is fastest.10162030Weeks of gestationBirthConceptionSource: WHO 2002.
21 Fetal Growth Velocity: Quickening LastmonthQuickeningQuickening refers to the time a mother feels the first movement of the fetus. It varies among women, with some women experiencing quickening as early as 16 weeks while others may not do so until 20 weeks gestation.10162030Weeks of gestationBirthConceptionSource: WHO 2002.
22 Rationale for the Timing of the SP Doses Fetal growth velocity RxRxLastmonthQuickeningThe World Health Organization or WHO recommends a schedule of four antenatal clinic visits, with three visits occurring after quickening. At least two doses of IPT should be delivered at scheduled antenatal care visits after quickening until delivery. SP should not be given more frequently than every four weeks. The concern about neonatal jaundice resulting from SP given after 36 weeks of gestation does not appear to be a major one at this time.Kenya, Malawi, Tanzania, Uganda and Zambia have embraced a two-dose SP regimen. In these countries, the first dose of SP is given between weeks and the second dose is given between weeks of pregnancy. No SP is given after 36 weeks. Countries with no policy should consider adopting a three-dose regimen that is in line with WHO’s 3 recommended scheduled antenatal visits after quickening.10162030Weeks of gestationBirthConceptionSource: WHO 2002.
23 Key Issues About Timing of Doses SP should be avoided during the first 16 weeks of pregnancy which is the period of initial development of the fetusIt is best to clear the placenta of parasites during the period of maximum fetal growthIPTp allows the mother to recover from anemia by clearing peripheral parasitemiaA note for the future – SP resistance is growing, and at some point a new medicine for IPTp will be foundMore on this laterSP should be avoided during the first 16 weeks of pregnancy which corresponds to the period of organ formation in order to avoid congenital malformations. It is best to clear the placenta of parasites during the period of maximum fetal growth as shown in the previous graph. IPT of malaria during pregnancy allows the mother to recover fully from anemia by clearing peripheral parasitemia.The question arises as to what protection a woman can have during these early weeks of pregnancy. The answer lies in early attendance at ANC where an Insecticide Treated Net can be received.
24 Steps for Providing IPTp with SP Determine quickening has occurredInquire about history of severe skin rash from previous SP useInquire about use of SP in last monthProvide three tablets of SP with clean water in a clean cupObserve the patient swallowing all three tablets (Directly Observed Treatment or DOT strategy)DOT is one reason to ensure that IPTp is an essential component of an integrated ANC programDo not encourage women to undertake IPTp on their ownWhen providing IPTp with SP it is important to determine that quickening has occurred . Inquire about any history of allergy to sulfonamides, including severe skin rash. Also inquire about the use of SP or any sulfonamides in the past month. When administering SP provide three tablets of SP with clean water in a clean cup, and directly observe the woman taking the SP tablets in the clinic. This helps to ensure compliance.
25 Steps for Providing IPTp with SP (continued) Record SP on the antenatal card and the clinic recordInstruct clients to return at next scheduled visit or earlier if she is feeling illDrop-out is a major challenge for successful IPTp programsFrom 20-50% of women do not receive a second doseInform clients that IPTp is most effective if they receive at least two dosesAsk about side effects from previous dose before giving the next dose, which should not be less than 4 weeks from the last doseMonitoring and evaluation is important. Therefore record that “SP given” in the woman’s antenatal card and clinic record. Instruct the woman to return at her next scheduled visit or earlier if she is feeling ill. Before giving any follow-up dose at the next visit, ask about side effects from the previous dose. A follow-up dose should not be given less than 4 weeks from the last dose.
26 SP Resistance and IPTpWaning efficacy of SP in treating symptomatic children <5 years does not equate with waning efficacy for prevention of malaria during pregnancyIPTp with SP remains efficacious even in settings with significant (<50%) treatment failure in symptomatic children 6-59 months of ageMore than 2 doses are likely beneficial given rising resistance

29 Appropriate case management Parasitological diagnosisTreatment with appropriate medicinesCounseling to ensure adherence
30 Case Management: Drug Efficacy Malaria episodes in pregnancy are serious and must be treated promptly with an appropriate drugEffective drugs are needed for P. falciparum malaria as it can be fatal to both mother and childRemember differences between stable and unstable transmission areasNote importance of diagnosisThe final component of the strategic framework for malaria control during pregnancy is case management. Effective drugs are needed for Plasmodium falciparum malaria because the disease can be fatal to both the mother and the newborn. The drug of choice for case management would depend on the profile of drug resistance in the country. For example, antimalarial drugs that would be considered appropriate for Uganda may be inappropriate for Tanzania. Chloroquine has been the drug of choice for many years and it will probably remain the drug of choice in some areas where it is still effective. But, because of the high incidence of chloroquine resistance in Africa, SP has become the alternative antimalarial drug of choice for treating uncomplicated malaria. Quinine given intramuscularly or intravenously is the drug of choice for the case management of complicated malaria.
31 Importance of diagnosis Laboratory/slide diagnosis is still the gold standardFew front line clinics have labs and/or trained staffRapid diagnostic tests are becoming more availableCan reduce treatment costs only treat ‘real’ malaria casesStorage issues in terms of temperature, expirey dates
33 Drug ChoiceDrug of choice depends on the geographic drug resistance profile and national malaria drug policiesQuinine is the drug of choice for malaria in first trimester pg pregnancySP is reserved for IPTpArtemisinin-based combination therapy (ACT) drugs can be used after the first trimesterThe drug of choice for case management would depend on the profile of drug resistance in the country. For example, antimalarial drugs that would be considered appropriate for Uganda may be inappropriate for Tanzania. Chloroquine has been the drug of choice for many years, but is declining in use because of the high incidence of chloroquine resistance in Africa, Quinine is the drug of choice in the first trimester or for the case management of severe malaria.As much as possible, SP is being reserved for IPTp, so it is not being used for case management in most countries.In many parts of Africa and worldwide, plasmodium falciparum malaria has become resistant to single-drug therapy. WHO therefore recommends that countries use a combination of drugs to fight malaria. A major advantage of combination therapy is that drug resistance is far less likely than with single-drug treatments.The simultaneous use of drugs that include a derivative of artemisinin, along with another antimalarial drug is called artemisinin-based combination therapy (ACT). This combination is currently the most effective treatment for malaria.
34 All Kinds of Malaria Drugs Are on the Market … but not all are safe or appropriate
35 Resistance to DrugsResistance of P. falciparum to antimalarial drugs is an ever increasing problemTo minimize the problem of drug resistance, encourage women to complete their course of antimalarial drugs, even when they feel betterDrug resistance is inevitable; therefore healthcare providers must stay informed about policy changes recommended by their Ministry of HealthResistance to drugs is an ever increasing problem and can occur very rapidly in as few as five years. To minimize this problem, women need to be encouraged to complete their medications as prescribed. For example, when women feel better on the second day after treatment with ACTs, they often tend to stop medication. This type of poor compliance encourages drug resistance. Service providers should educate clients about the importance of medication adherence whenever providing medications to clients to be taken outside the health facility.In any case, because drug resistance is virtually inevitable, healthcare providers must stay informed about the changing policy of malaria drug therapy in their countries.
36 Drugs Not To Be Used During Pregnancy TetracyclineCause abnormalities of skeletal and muscular growth, tooth development, lens/corneaDoxycyclineRisk of cosmetic staining of primary teeth is undeterminedExcreted into breast milkPrimaquineHarmful to newborns who are relatively Glucose-6-Phosphatase-Dehydrogenase (G6PD) deficientHalofantrineNo conclusive studies in pregnant womenHas been shown to cause unwanted effects, including death of the fetus, in animalsSome drugs should not be used during pregnancy. These include tetracycline, doxycycline, primaquine and halofantrine. Tetracycline can cause abnormalities of skeletal and muscular growth and damage the teeth of the newborns. While there are no controlled studies of doxycycline use in pregnant women to show safety, an expert review of published data on experiences with doxycycline use during pregnancy concluded that the available data are insufficient to state that there is no risk. The risk of cosmetic staining of the primary teeth by doxycycline is also undetermined (quantity and quality of data has been very limited). Doxycycline is excreted into breast milk. Short-term use by lactating women is not necessarily contraindicated; however, the effects of prolonged exposure to doxycycline in breast milk are unknown.Halofantrine has not been adequately studied in pregnant women. However, it has been found to cause unwanted effects in animals, including death of the fetus.Primaquine, on the other hand, can cause jaundice in newborns who are relatively deficient in Glucose-6-Phosphate-Dehydrogenase enzyme.The safety of other newer antimalarials such as mefloquine, artemisinin derivatives, malarone and co-artemether during pregnancy are still subjects of research.
37 Insecticide Treated Nets Start net use as early in pregnancy as possibleOur third section continues with discussion of MIP interventions. Pregnant women must be included in plans to provide insecticide treated nets in the community. Planning is also needed to ensure there is adequate medicine available to treat pregnant women who develop malaria disease.
38 Insecticide-Treated Nets (ITNs) An ITN is a mosquito preventing bednet (or other netting material such as curtains) that has been soaked in a safe insecticideThe insecticide kills the mosquito when it comes near the sleeping personTraditional ITNs required re-treatment with insecticide every six monthsWhile ITNs are still available in many countries, most are switching to long lasting insecticide-treated nets (LLINs) where the insecticide is applied at the factoryLLINs can withstand washing up to 20 times and may last over 4 yearsThe third component of the strategic framework for malaria control during pregnancy is the use of insecticide-treated nets (ITNs) to protect mothers and their newborns.An ITN is a netted material that has been soaked in a safe insecticide. The most common use is in the form of a bednet, though the material can be used to protect windows and doors also. ITNs work through the insecticide that kills (or repels) the mosquito when it comes in contact with the net or near the sleeping person. Traditional ITNs require re-treatment with insecticide about every 6 months and are still available in many countries. However, most countries are switching to long lasting insecticide treated nets (LLINs). These factory-treated nets can withstand washing up to 20 times and may last 4 years or more.
39 Use ITNs/LLINsThe use of ITNs/LLINs have been shown to result in reduction of newborns born with low birth weight or prematurelyITNs reduce transmission by physically preventing vector mosquitoes from landing on sleeping personsThe use of insecticide-treated nets have been shown to result in a reduction in the proportion of newborns born with low birth weight or born prematurely (that is, before 37 completed weeks of pregnancy). Insecticide-treated nets also reduce malaria transmission by serving as a physical barrier between the vector mosquitoes and people sleeping inside the nets.
40 ITN/LLIN BenefitsRepel and kill mosquitoes that come in contact with the netKill other insects like cockroaches, lice, ticks and bed bugsShould be used by pregnant women as early during pregnancy as possible and use should be encouraged throughout pregnancy and in the postpartum periodNets have a variety of benefits and should be provided to a pregnant woman as early in pregnancy as possible.They repel or kill mosquitoes that land on the net and can also kill bed bugs, lice, ticks, cockroaches and other insects around the house. They should be used by pregnant women as early as possible during pregnancy and their use should be continued throughout pregnancy and in the postpartum period.A study from western Kenya showed that women who were protected by insecticide-treated nets every night during their first four pregnancies delivered approximately 25% fewer newborns who were either small for gestational age or born prematurely when compared to women who were not protected by insecticide-treated nets,

The use of insecticide-treated nets was also associated with a 23% reduction in placental malaria, 28% reduction in incidence of low birth weight newborns and a 25% reduction in any adverse birth outcome. There is, however, no evidence to suggest that the efficacy of insecticide-treated nets decreases with increasing levels of malaria transmission in the area.Source: Shulman 2001: Western Kenya

45 ITN/LLIN Procurement and Management It is quite popular these days to provide ITNs within childhood immunization campaignsIt is less common to find that ITNs have been allocated in adequate numbers to be given out as an essential component of focused ANCThe district health management team needs to meet and plan for adequate nets, not only for children under five years of age, but also ensure that adequate nets are supplied to ANC clinicsITN/LLIN provision can be an important incentive to attend ANCA woman should get a net on her first ANC visit when it can offer the most protection during pregnancyWhile providing ITNs at childhood immunization campaigns have become popular, nets are not yet part of routine maternal and child health care, especially the provision of adequate ITNs as an essential component of focused ANC. District health management teams and/or other local authorities need to incorporate adequate planning and resource allocation to meet the urgent need for ITNs in both under-fives and pregnant women. Regular provision of an ITN/LLIN can be an important incentive for pregnant women to attend ANC. To get the maximum protection during pregnancy, an ITN should be offered to a woman on her first ANC visit.

48 Most women attend ANC in Africa, but they may not make two visits that support IPT compliance Recall our earlier slide showing ANC attendance. Also remember that IPTp must be given at least twice after quickening with doses at least one month apart. This graph shows that although overall registration for ANC is good, not all women come back for a second visit, and if they do the timing may not be compatible with receiving IPTp twice as recommended.*E Eckert, A Hyslop, R Snow, MEASURE Evaluation, Macro International, APHA 2005

55 Antenatal Care as a Platform for MIP Control Antenatal visits provide a unique opportunity for:Monitoring of maternal and fetal health during pregnancyimmunizationsProvision of micronutrients (e.g., iron folate)Health education about malaria during pregnancyIPTp with sulfadoxine-pyrimethamine (SP)ITN distributionPrompt diagnosis and treatment of malariaPrevent mother-to-child transmission of HIVDistrict health teams must promote timely ANC attendance if MIP interventions are to reach the maximum number of pregnant womenFor any program on malaria control during pregnancy to be successful, there must be a partnership between the providers of maternity services and malaria control staff. Antenatal clinic visits provide a unique opportunity to educate women about the effects of malaria on pregnancy and about what can be done to eliminate or minimize its adverse consequences. These interventions will include monitoring of maternal and fetal health, provision of micronutrient supplementation to reduce the risk of anaemia, education on the benefits of using insecticide-treated nets, application of intermittent preventive treatment and case management of malaria illness.

58 Bad Combination: Placental Parasitemia and HIV Placental Parasitemia by HIV Status and Pregnancy Number, Kenya,Parasite density/mm3% parasitemicHIV infection, which is becoming more prevalent in women of reproductive age, may diminish a pregnant woman’s capacity to control Plasmodium falciparum malaria infections and lead to decreased efficacy of antimalarial interventions.This graph summarizes the findings from a study in Kenya. The cluster of bars to the left represent HIV-positive mothers, and the bars to the right represent HIV-negative mothers. The data shows that, irrespective of placental parasite density or whether the women are in their first, second or later pregnancies, those who are HIV-positive are more likely to have malaria parasitemia when compared with those who are HIV-negative. Because the HIV virus is an immunodeficiency virus, HIV-positive women have lower levels of acquired immunity for all infections including malaria. The implication of this finding for treatment is that HIV-positive women have a reduced efficacy to antimalarial medication and need more doses of the medication than their HIV-negative counterparts.231159197772402479HIV (+)HIV (-)Summary RR = 1.63 ( ), p <0.001Total n = 2263Source: van Eijk AM et al 2001.

63 SummaryMalaria during pregnancy has adverse consequences for mothers and their babiesMalaria preventive package includes:Intermittent preventive treatment during pregnancy with SP during antenatal clinic visitsUse of ITNs/LLINs throughout pregnancy and in the postpartum periodPrevention must be complemented by effective case management of malaria illness for all women of reproductive ageHealth Systems issues must be addressed from national to facility level to ensure full delivery of MIP servicesIn summary, malaria during pregnancy has been shown to have adverse consequences for both mothers and their babies. However, a malaria prevention package has also been shown to minimize these adverse events.An effective preventive package includes intermittent preventive treatment with a dose of SP given at each antenatal care visit after quickening (but no less than 4 weeks apart) to ensure that the pregnant woman receives at least two doses. The package also includes the use of insecticide-treated nets throughout pregnancy and during the postnatal period. Preventive efforts must be complemented by case management of malaria illness with effective antimalarial medication for all women of reproductive age and should emphasize screening and prompt treatment of anemia. Successful programs can only emerge from partnerships between malaria control and reproductive health units.For more information about malaria during pregnancy, including job aids, visit the Resources section of this tutorial.
