Twenty Years of Malaria Day Observances: Jhpiego at the Forefront

In 2001 the first Africa Malaria Day (AMD) was observed. The opportunity to mark progress and exhort increased efforts for the continent continued through 2007. Then in 2008, the concept of World Malaria Day (WMD) took over, though it could not be denied that the bulk of malaria morbidity, mortality and intervention still was focused on African countries. Other countries have made progress such as the recent certification of malaria elimination in Argentina and El Salvador, but twenty years after the first AMD/WMD, Africa is still leading the way for creative, sustained intervention against the disease, despite threats to resources from economic downturns and new pandemic diseases.

Below we go straight to Africa to share activities and observances of WMD 2021 from Jhpiego’s African Malaria Technical Officers. After reading through, please watch “Jhpiego Leaves No One Behind | World Malaria Day, 2021″ on YouTube.

“Saramed” from Guinea reports that Guinea, like other countries in the world, celebrates World Malaria Day under the theme: ” Zero Malaria, Draw a Line on Malaria “. We are currently conducting the following activities:

  • Lectures and debates on malaria in medical faculties and health schools;
  • Animation of debate programs on malaria in public and private radios and televisions of the country,
  • Advocacy and sensitization of religious and other influential people
  • Carrying out a package of activities (administration of IPT to pregnant women who have missed their ANC appointment, community distribution of LLINs, screening and treatment of confirmed cases, awareness raising on malaria) in high incidence localities.

These activities is in line with the WHO approach of “high burden, high impact”.

Noella Umulisa reports that the WMD celebration took place in Eastern Province, in Bugesera district in the Mareba sector. Due to COVID-19 pandemic ,only 100 persons were invited to the event.This year’s the national theme is “Zero Malaria starts with me”.

Key activities during the event included …

  • Visit of breeding sites under sentinel surveillance
  • Visit of indoor residual spraying (IRS) sites
  • Launching of the Awareness of the population using drones on the ongoing IRS campaign in this time of COVID-19
  • Song by CHWs
  • Certificate to Integrated Vector Management (IVM) Training of Trainers who will train others up to village level
  • Speech of the Director General ,the guest of honor.

From Burkina Faso, Yousseff Sawadogo and Moumouni Bonkoungou shared photos of the celebration that featured a giant Insecticide-Treated  Net, a speech by the US Ambassador, a malaria song composed by a nurse, an official speech by the President of the National Assembly, and national recognition given to one of the current Jhpiego staff members, Thiery Ouedraogo, who at one time also served as director of the national malaria control program. He was decorated by the country’s authorities as a knight of the order of merit.

Bright Orgi from Jhpiego’s TiPToP malaria in pregnancy project in Nigeria ?? shared photos from a series of compound meetings in the community to mark WMD 2021. The meetings focused on malaria prevention and treatment. Provided opportunities to rural communities to ask questions on malaria issues. Here we can see that observance of WMD must be taken to the people who actually suffer from malaria and need to be actively involved in its solution. Deo Cibinda from the Democratic Republic of the Congo share photos of a national celebration, seen to the left.

Finally, As Kristen Vibbert noted, “These are such amazing World Malaria Day stories. I’m so heartened to see all of these great country efforts to remind everyone of how the fight against malaria must continue despite the Covid-19 pandemic.”  Charles Wanga tweeted, “We know how to defeat #malaria. But that’s not enough. We must do more to save pregnant women and children from the deadly scourge. This #WorldMalariaDay and everyday, because@Jhpiego leaves no one behind in our fight to #EndMalaria for good in Africa, and everywhere”

Malaria in Pregnancy &Mentoring &mHealth Bill Brieger | 18 Nov 2020

Mentorship to Strengthen Quality of Malaria Case Management & Malaria in Pregnancy, Zimbabwe

Gilson Mandigo et al. examine how mentoring can be achieved from a distance in Zimbabwe. Their presentation at the 69th Annual Meeting of American Society of Tropical Medicine and Hygiene of “Mentorship to Strengthen Quality of Malaria Case Management And Malaria in Pregnancy (MIP) in Zimbabwe: Lessons Learned From One Year of Implementation” is shared below.

Despite significant investment in training and supervision of facility-based health workers in Zimbabwe, persistent malaria case management and MIP gaps remain. National Malaria Control Program and US President’s Malaria Initiative developed and implemented a mentorship intervention in five high burden malaria districts to motivate provider performance and improve quality services.

From June 2018 – June 2019, 25 health workers proficient in malaria service delivery were selected and trained in clinical mentorship. These individuals mentored 98 providers at 25 facilities, covering clinical case reviews, bedside coaching, simulations, and records review. USAID’s Zimbabwe Assistance Project in Malaria subsequently assessed the mentorship program through review of patient records, feedback from mentors and mentees, and engagement of stakeholders.

Record review compared practices before and after implementation, using a checklist that noted completeness and appropriateness of case management across multiple parameters, including physical examination, diagnosis, classification and treatment. Mentored facilities documented improvements in recommended practices across registers: 58% to 63% for outpatient clinical settings, 53% to 64% for integrated management of neonatal and childhood illnesses, and 72% to 76% for antenatal care.

A phone-based e-survey of 49 mentees and 21 mentors elicited positive feedback on the mentorship approach: 62% of mentors were “very satisfied” with the program, 67% reported quality improvement and 86% benefited from learning new skills. Among mentees:

  • 60% were “very satisfied”,
  • 67% said that the program has improved service quality and
  • 97% benefited from learning new skills

Common challenges included mentor transportation, mentee availability, and commodity availability. Through a review meeting, stakeholders recommended the intervention continue, as it was acceptable, feasible and achieved promising results. Recommendations include prioritizing high-volume facilities, integrating management of mentorship into District Health Executive functions and use of low-cost communication platforms to aid virtual mentorship.

Antenatal Care (ANC) &Malaria in Pregnancy Bill Brieger | 18 Nov 2020

Group Antenatal Care to Improve Malaria in Pregnancy & ANC in Geita, Tanzania

Jasmine Chadewa and colleagues are sharing their work on Group Antenatal Care (GANC): A Baseline Initiative to Improve Malaria in Pregnancy & ANC Indicators. A Case from Geita Tanzania at the virtual 69th Annual Meeting of American Society of Tropical Medicine and Hygiene. See their findings below.

Malaria in pregnancy (MiP) is a major public health concern contributing to poor maternal and newborn health outcomes. Early and frequent Antenatal Care attendance (ANC) could address this problem. Early ANC booking is still low in Tanzania. USAID Boresha Afya and Tanzania Ministry of Health introduced a Group Antenatal Care (GANC) initiative in Geita region where malaria prevalence is high. This model brings 8-15 pregnant women of similar gestational age together for ANC. Group contacts last 1.5-2 hours, and include clinical care, information sharing, and peer support to improve quality of care and women’s engagement, leading to better retention in care.

Prior to implementation, a baseline cross-sectional household survey was conducted in December 2019 in 40 communities across Geita region. The survey was intended to identify gaps and targets in MiP services delivery which could be addressed through GANC. Women who had delivered a live born infant in the preceding 12 months were included. We interviewed 1111 women; mean age was 27 years. One-third had no education and only 9% had secondary education.

Nearly all 95% of women lived in a house with an Insecticide Treated Net (ITN); 87% reported receiving an ITN during their last pregnancy and 90% reported ITN use on the night before the survey. Nearly all 98% attended ANC at least once, with 17% attending in first trimester. Only 45% attended ?4 visits; 6% of women were stopped by their husbands from attending ANC.

Median total time spent away from the home for each ANC was 4 hours. 88% received Intermittent Preventive Treatment of malaria in pregnancy (IPTp), with 53% receiving the recommended 3 or more doses. Among those who did not receive IPTp, 42% reported that the provider did not offer it and 25% reported it was not available at the facility. Receipt of other interventions varied: 64% reported that their blood pressure was checked, 95% and 57% had blood and urine samples collected, 74% had received adequate doses of tetanus vaccination, and 94% received iron/folate supplements.

We will assess whether GANC improves MiP services as well as quality of ANC care, to promote positive pregnancy outcomes.

What could hinder IPTp uptake?

Cristina Enguita-Fernàndez and colleagues share findings on from a qualitative study on the acceptability of a community-based approach to IPTp delivery in 4 sub-Saharan countries in the UNITAID TiPTop project. Their poster is available at the vitrual 69th Annual Meeting of American Society of Tropical Medicine and Hygiene.

Increasing uptake of intermittent preventive treatment of malaria in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) is key to improving maternal health indicators in malaria endemic countries, yet current coverage rates remain low. This qualitative study is part of a project evaluating the acceptability of a community-based approach to the delivery of IPTp (C-IPTp) through community health workers (CHWs) in 4 countries: the Democratic Republic of Congo (DRC), Madagascar, Mozambique and Nigeria.

Between March 2018 and February 2020 a total of 435 in-depth interviews and 181 focus group discussions were carried out in the four country sites with pregnant women, relatives, women of reproductive age, community leaders, CHWs, and health providers. These were combined with direct observations of both community and facility based IPTp delivery.

Grounded theory guided the study design and data collection, and data were analysed following a combination of content and thematic analysis to identify barriers to IPTp uptake. Although the novel C-IPTp intervention overcomes some access barriers (such as distance from health care providers, and travel costs), the study identified important barriers, some of which cut across delivery mechanisms and others that are specific to the C-IPTp approach.

Cross-cutting barriers consisted of perceived attributes of SP that explain treatment refusal. These consisted of sensorial characteristics, including the drug’s perceived foul smell, taste and large size; experiences with adverse drug effects, such as nausea and weakness; fears of adverse pregnancy outcomes, such as miscarriages or oversized babies leading to C-sections.

Attributes originated either in individual experiences of SP intake or were socially transmitted. Barriers specific to C-IPTp were centered around concerns over trust in CHWs as adequate providers of maternal healthcare and their competence in delivering IPTp. Despite sensitization activities, misinformation could still be determining these barriers. Ensuring an improved awareness of SP effects and its use, as well as a better understanding of the intervention should lead to enhanced C-IPTp adherence

CHWs at data validation meeting during COVID 19 pandemic social distancing

Organization recommended minimum of three doses of IPTp with Sulfadoxine-Pyrimethamine (SP) compared to 17% in Nigeria (DHS, 2018). In order to expand the coverage of this life-saving intervention, the Transforming Intermittent Preventive Treatment for Optimal Pregnancy project engaged community health workers (CHWs) to introduce the delivery of community IPTp (C-IPTp) to eligible pregnant women, in addition to women being able to access IPTp at antenatal care in Ohaukwu district of Ebonyi State, Nigeria.

Community meeting in Bosso

As findings from studies in Nepal and Uganda showed that the sex of CHWs were correlated with uptake of iCCM services, we examined routine project data to determine if the sex of the CHWs was correlated with uptake of IPTp. Of the 462 CHWs selected, 49% were male and 51% were female and were deployed at a ratio of one CHW to 27 pregnant women. All CHWs were trained on early identification of pregnant women, referral to antenatal care and provision of C-IPTp using SP.

A trained data analyst extracted routine data from the national community health management information system for 13,733 pregnant women who received IPTp from CHWs between June and November 2019. Data abstracted included CHW sex and number of PW that received IPTp. Findings showed that female CHWs distributed 60% of IPTp1, 65% IPTp2, and 61% IPTp3 (p-value=0.00 for all comparisons). The data suggest that trained female CHWs may reach more pregnant women than their male counterparts in community directed IPTp interventions.

Antenatal Care (ANC) &IPTp &Malaria in Pregnancy Bill Brieger | 16 Nov 2020

Achieving antenatal care attendance and intermittent preventive treatment in pregnancy in Geita, Tanzania

Ryan Lash and colleagues examined factors associated with achieving antenatal care (ANC) attendance and intermittent preventive treatment in pregnancy (IPTp) and made recommendations in Geita Region, Tanzania, 2019. There findings are being presented at the virtual 69th Annual Meeting of American Society of Tropical Medicine and Hygiene.

Malaria in pregnancy results in an estimated 10,000 maternal and 100,000 infant deaths globally each year. To reduce this burden, the World Health Organization (WHO) recommends pregnant women in high to moderate malaria transmission areas receive at least 3 doses of intermittent preventive treatment in pregnancy (IPTp3) with sulfadoxine-pyrimethamine (SP) starting in the second trimester as part of routine antenatal care (ANC). Tanzania has national coverage goals of 80% coverage for women receiving IPTp3 and at least four ANC visits (ANC4).

We surveyed women 15-49 years who had given birth in the last 12 months from randomly selected households across 40 communities in Geita Region, Tanzania. ANC attendance and IPTp uptake was recorded from respondent ANC cards if available, or self-reported. Predictors of ANC4 and IPT3 uptake were identified using logistic regression modeling, accounting for clustering and controlling for gravidity.

Of 1,111 women surveyed, 505 (51.9%) received IPTp3 and 472 (43.4%) achieved ANC4. Among women who achieved ANC4, 295 (62.5%) received IPTp3. IPTp3 was associated with basic knowledge about ANC and IPTp (aOR 2.4, CI 1.9 -3.1), initiating ANC <20 weeks (aOR 1.7, CI 1.3-2.3), waiting at the facility for <120 minutes (aOR 1.4, CI 1.1-1.9), and receiving advice from a health worker about SP (aOR 1.7, CI 1.3-2.2).

ANC4 was associated with better access to care (aOR 1.9, CI 1.3-2.8, for travelling <3.75 km to ANC and aOR 1.9, CI 1.1-2.2, for waiting <90 minutes for the provider), initiating ANC at <20 weeks gestation (aOR 10.7, CI 8.2-14.1), and basic knowledge about ANC and IPTp (aOR 1.4, CI 1.0-1.9). Poor access to care and late initiation of ANC reduced the likelihood that women will attend 4 ANC visits. Knowledge was a predictor of both ANC attendance and IPTp uptake; increasing women’s health literacy may overcome some of the barriers associated with retention in ANC.

New approaches to delivering ANC that focus on improving knowledge and the experience of care among ANC clients could help close coverage gaps for ANC4 and IPTp3 in Tanzania

Provider Communication about IPTp and ITNs for Pregnant Women in Tanzania

Courtney Emerson and co-workers address the issues of Intermittent Preventive Treatment of Malaria with Sulfadoxine Pyrimethamine and Provision of Insecticide Treated Nets in Geita, Tanzania: Provider Communication and Opportunities at the virtual 69th Annual Meeting of American Society of Tropical Medicine and Hygiene. See their findings below.

Intermittent preventive treatment of malaria in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) is a life-saving intervention to reduce morbidity and mortality among pregnant women and their infants. Additionally, provision and use of insecticide treated nets (ITNs) to prevent malaria is critical to improving pregnancy outcomes.

To assess implementation of malaria in pregnancy services and related health communications, we surveyed 1111 women who had delivered a live born infant in the preceding 12 months (recently pregnant women), as well as 1194 adults from randomly selected households without a recently pregnant woman in Geita Region, Tanzania in 2019. Most (88.2%) recently pregnant women reported receiving any IPTp dose; 45.5% received 3 doses. 72.3% of women received their first dose in the second trimester, as recommended by national guidelines, but only 14.4% received IPTp in the 4th month; 20.3% of women did not receive IPTp until third trimester.

There was a significant difference between ITN ownership and use among households (HH) with and without a recent pregnancy: ownership of at least one net was 95.2% vs 87.9%, respectively (p<0.0001), and use was 90% vs 77.8%, respectively (p<.0001). Despite this, few HHs had enough ITNs to cover all residents; on average, HHs had 1 ITN for every 3 rather than every 2 people, as recommended. Notably, only 21.2% and 26.2% of HH with and without a recent pregnancy had sufficient ITNS (p=0.005), despite 87.3% of recently pregnant women receiving an ITN during their last pregnancy.

Of recently pregnant women, 87% received advice on preventing malaria from a health worker. Of these, 82.7% were advised to sleep under an ITN, but only 66.4% were advised to take SP, and 52.1% to attend ANC regularly. Although uptake of any IPTp was high, there are critical messages that need to be more consistently communicated to pregnant women by ANC providers including the importance of attending ANC regularly during pregnancy. To improve outcomes among pregnant women, additional net distribution may be warranted due to the unexpectedly low access.

IPTp &ITNs &Malaria in Pregnancy Bill Brieger | 16 Nov 2020

Scoping Review of the Key Determinants and Indicators of Malaria in Pregnancy, Madagascar (2010-2019)

This year the 69th Annual Meeting of American Society of Tropical Medicine and Hygiene is virtual.  Catherine Dentinger and colleagues (see authors below) gathered information to guide partner planning to combat malaria in pregnancy in Madagascar. Here are their findings.

Malaria in pregnancy (MIP) increases the risk of poor maternal and infant outcomes; to prevent this, the World Health Organization (WHO) recommends insecticide-treated net (ITN) use, intermittent preventive treatment during pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP), and prompt case management. In Madagascar, IPTp uptake remains low; 10% of targeted women receive 3 doses.

To determine if additional data are needed to improve MIP activities, we conducted a scoping review to identify barriers to antenatal care (ANC) and IPTp uptake. We searched PubMed, Google Scholar and USAID’s files (Development Experience Catalog) using the terms “Madagascar” and “pregnancy” and “malaria” and collected materials from stakeholders. We included English and French documents from 2010 to 2019 with quantitative or qualitative data regarding malaria during pregnancy.

Documents were reviewed and categorized as MIP background information, care seeking, and facility readiness. Of 69 project reports, surveys and published articles, 15 (22%) met the inclusion criteria; 4 (27%) were categorized as care seeking, 4 (27%) as background, and 7 (47%) as facility readiness.

Eight (53%) articles mentioned SP stock outs, 3 (20%) mentioned poor provider knowledge of IPTp guidelines despite recent training, and 5 (33%) discussed barriers to ANC including distance, wait times, poor service quality, cost, and unfriendly providers. One study found only 30% of targeted health workers received recommended supervision.  A 2015 survey of 52 health facilities revealed limited access to ANC due to financial and geographic barriers; 2018 surveys revealed similar findings. Self-treatment and care-seeking delays were reported even when distance was not a barrier.

Our review revealed well-documented barriers to MIP services that could be mitigated by reducing stock outs, improving access to healthcare by removing fees and providing services closer to women’s homes, and targeted behavior change. These findings can be used to guide coordinated donor and government efforts to address management, financial, and human resource gaps to improve MIP services.

Malaria News Today 2020-10-26: Haiti, India, Malaysia, Cape Verde

Recent news and abstracts explore malaria on three continents. Genetic aspects of malaria are studied in Haiti as well in Malaysia. Use of fish to control malaria carrying mosquitoes are successful in India. The movement toward malaria elimination is examined in Cape Verde. Finally, Non-invasive diagnostic tests are recognized/rewarded by NIH. Read more by following the links below.

NIH Awards Prize to Hemex Health’s Non-Invasive Sickle Cell, Malaria, Anemia Rapid Test (“SMART”) Diagnostic Technology

Researchers from Hemex Health, Medtronic plc, Case Western Reserve University, and the University of Nebraska Medical Center’s International Foundation Against Infectious Disease in Nigeria (IFAIN) were awarded 3rd place and $100,000 in the NIH Technology Accelerator Challenge.  Code named, SMART (Sickle, Malaria, Anemia, Rapid Test), the system includes non-invasive diagnostics for sickle cell, malaria, and anemia. The project seeks to build on Hemex Health’s Gazelle® platform, which currently includes minimally invasive tests (using a drop of blood) for malaria, the detection and quantification of hemoglobin variants, as well as for total hemoglobin for anemia determination.

The non-invasive test will screen for anemia, malaria, and sickle cell disease using an optical finger sensor similar to the way blood oxygen is measured. An advantage of combining the non-invasive and minimally invasive diagnostics is, when needed, more diagnostic information and confirmation is available on the same platform. The goal is a one-minute, $0.25 non-invasive malaria, sickle cell, and anemia test. “The world desperately needs easy-to-use diagnostic technologies with the flexibility needed to meet viruses and diseases in every corner of the planet,” said Ms. White.

Controlling Mosquitoes: Ramanathapuram district inches closer to malaria-free status

Steps taken by the Ramanathapuram district administration to control mosquito breeding for the last five years has enableed the district inch closer to being declared a ‘malaria-free district, with only one malarial fever case having been reported till September, this year. Last year, the district reported 43 cases.

One of the initiatives is to bring guppy fish from the Ayyankulam tank in Tiruvannamalai district and let them into all wells and tanks of the districts in 3:1 ratio (3 familes/one male). The fish thrives, eating the mosquito larvae and eggs and the incidence of malaria came down in the district.

Updates on malaria epidemiology and profile in Cabo Verde from 2010 to 2019: the goal of elimination

Located in West Africa, Cabo Verde is an archipelago consisting of nine inhabited islands. Malaria has been endemic since the settlement of the islands during the sixteenth century and is poised to achieve malaria elimination in January 2021. The aim of this research is to characterize the trends in malaria cases from 2010 to 2019 in Cabo Verde as the country transitions from endemic transmission to elimination and prevention of reintroduction phases. All confirmed malaria cases reported to the Ministry of Health between 2010 and 2019 were extracted from the passive malaria surveillance system.

A total of 814 incident malaria cases were reported in the country between 2010 and 2019, the majority of which were Plasmodium falciparum. Cabo Verde has made substantial gains in reducing malaria burden in the country over the past decade and are poised to achieve elimination in 2021. However, the high mobility between the islands and continental Africa, where malaria is still highly endemic, means there is a constant risk of malaria reintroduction. Characterization of imported cases provides useful insight for programme and enables better evidence-based decision-making to ensure malaria elimination can be sustained.

Genetic analysis reveals unique characteristics of Plasmodium falciparum parasite populations in Haiti

With increasing interest in eliminating malaria from the Caribbean region, Haiti is one of the two countries on the island of Hispaniola with continued malaria transmission. While the Haitian population remains at risk for malaria, there are a limited number of cases annually, making conventional epidemiological measures such as case incidence and prevalence of potentially limited value for fine-scale resolution of transmission patterns and trends. In this context, genetic signatures may be useful for the identification and characterization of the Plasmodium falciparum parasite population in order to identify foci of transmission, detect outbreaks, and track parasite movement to potentially inform malaria control and elimination strategies.

This study evaluated the genetic signals based on analysis of 21 single-nucleotide polymorphisms (SNPs) from 462 monogenomic (single-genome) P. falciparum DNA samples extracted from dried blood spots collected from malaria-positive patients reporting to health facilities in three southwestern Haitian departments (Nippes, Grand’Anse, and Sud) in 2016.

437 of the 462 samples shared high levels of genetic similarity–at least 20 of 21 SNPS–with at least one other sample in the dataset. These results revealed patterns of relatedness suggestive of the repeated recombination of a limited number of founding parasite types without significant outcrossing. These genetic signals offer clues to the underlying relatedness of parasite populations and may be useful for the identification of the foci of transmission and tracking of parasite movement in Haiti for malaria elimination.

Epidemiology of malaria among pregnant women during their first antenatal clinic visit in the middle belt of Ghana

A total of 1655 pregnant Ghanaian women aged 18 years and above with a gestational age of 13–22 weeks, who attended an antenatal care (ANC) clinic for the first time, were consented and enrolled into the study. A structured questionnaire was used to collect socio-demographic and obstetric data and information on use of malaria preventive measures. Venous blood (2 mL) was collected before sulfadoxine-pyrimethamine administration. Malaria parasitaemia and haemoglobin concentration were determined using microscopy and an automated haematology analyser, respectively.

One out of five pregnant women attending their first ANC clinic visit in an area of perennial malaria transmission in the middle belt of Ghana had Plasmodium falciparum infection. Age???25 years, multigravid, educated to high school level or above, and in household with higher socio-economic status were associated with a lower risk of malaria parasitaemia. Majority of the infections were below 1000 parasites/µL and with associated anaemia. There is a need to strengthen existing malaria prevention strategies to prevent unfavourable maternal and fetal birth outcomes in this population.

Genetic diversity of circumsporozoite protein in Plasmodium knowlesi isolates from Malaysian Borneo and Peninsular Malaysia

Understanding the genetic diversity of candidate genes for malaria vaccines such as circumsporozoite protein (csp) may enhance the development of vaccines for treating Plasmodium knowlesi. Hence, the aim of this study is to investigate the genetic diversity of non-repeat regions of csp in P. knowlesi from Malaysian Borneo and Peninsular Malaysia.
The phylogenetic analysis revealed indistinguishable clusters of P. knowlesi isolates across different geographic regions, including Malaysian Borneo and Peninsular Malaysia.

The csp non-repeat regions are relatively conserved and there is no distinct cluster of P. knowlesi isolates from Malaysian Borneo and Peninsular Malaysia. Distinctive variation data obtained in the C-terminal non-repeat region of csp could be beneficial for the design and development of vaccines to treat P. knowlesi.

Malaria News Today 2020-10-15

Recent publications in Malaria Journal, The Lancet and eLife tackle several challenges to saving lives and malaria elimination. Problems include low access to bednets for children in Ethiopia, high prevalence of asymptomatic malaria in Ghanaian adults, risk of co-infection with other infectious diseases, and gaps in current interventions to prevent malaria in pregnancy and children. On the hopeful side, new targets for drug therapy are being identified. Read more on each by following the links below.

Long-lasting insecticide-treated bed net ownership, utilization and associated factors among school-age children in Southern Ethiopia

Zerihun Zerdo and colleagues examined net use among children in malaria-prone areas of

Dara Mallo and Uba Debretsehay districts because malaria is one of the major causes of morbidity and mortality among school-age children (SAC) in sub-Saharan Africa. This study was part of a baseline assessment in a cluster-randomized controlled trial.

The ownership of at least one LLIN by households of school-aged children (SAC) was about 19.3% (95% CI 17.7–21.0%) but only 10.3% % (95% CI 7.7–13.7%) of these households had adequate access of bed nets to the household members. Ownership of bed net was lower than universal coverage of at least one bed net for two individuals. It is important to monitor replacement needs and educate mothers with low education level with their SAC on the benefit of consistent utilization of bed nets.

Prevalence of and risk factors for Plasmodium spp. co-infection with hepatitis B virus: a systematic review and meta-analysis

Kotepui and Kotepui observed that Plasmodium spp. and hepatitis B virus (HBV) are among the most common infectious diseases in underdeveloped countries. Therefore they examined co-infection in people living in endemic areas of both diseases. The PubMed, Web of Science, and Scopus databases were searched. Observational cross-sectional studies and retrospective studies assessing the prevalence of Plasmodium species and HBV co-infection were examined. and found 22 studies to include in a systematic review and meta-analysis. Overall, the pooled prevalence estimate of Plasmodium spp. and HBV co-infection was 6% (95% CI 4–7%, Cochran’s Q statistic?<?0.001, I2: 95.8%).

No difference in age or gender and risk of Plasmodium spp. and HBV co-infection group was found. The present study revealed the prevalence of Plasmodium spp. and HBV co-infection, which will help in understanding co-infection and designing treatment strategies. Future studies assessing the interaction between Plasmodium spp. and HBV are recommended.

High prevalence of asymptomatic malaria infections in adults, Ashanti Region, Ghana, 2018

Melina Heinemann and co-researchers noted that Ghana is among the high-burden countries for malaria infections and recently reported a notable increase in malaria cases. While asymptomatic parasitaemia is increasingly recognized as a hurdle for malaria elimination, studies on asymptomatic malaria are scarce, and usually focus on children and on non-falciparum species. Therefore asymptomatic adult residents from five villages in the Ashanti Region, Ghana, were screened for Plasmodium species by rapid diagnostic test (RDT) and polymerase chain reaction (PCR) during the rainy season. Samples tested positive were subtyped using species-specific real-time PCR.

Molecular prevalence of asymptomatic Plasmodium infection was 284/391 (73%); only 126 (32%) infections were detected by RDT. While 266 (68%) participants were infected with Plasmodium falciparum, 33 (8%) were infected with Plasmodium malariae and 34 (9%) with P. ovale. The sub-species P. ovale curtisi and P. ovale wallikeri were identified to similar proportions. Non-falciparum infections usually presented as mixed infections with P. falciparum.

Most adult residents in the Ghanaian forest zone are asymptomatic Plasmodium carriers. The high Plasmodium prevalence not detected by RDT in adults highlights that malaria eradication efforts must target all members of the population. Beneath Plasmodium falciparum, screening and treatment must also include infections with P. malariae, P. o. curtisi and P. o. wallikeri.

Scientists shed new light on mechanisms of malaria parasite motility

eLife reports a new insight on the molecular mechanisms that allow malaria parasites to move and spread disease within their hosts has just been published. The first X-ray structures of the molecular complex that allows malaria parasites to spread disease highlight a novel target for antimalarial treatments.

The movement and infectivity of the parasite Plasmodium falciparum, and ultimately its ability to spread malaria among humans, rely on a large molecular complex called the glideosome. The new findings provide a blueprint for the design of future antimalarial treatments that target both the glideosome motor and the elements that regulate it.

New Lancet Series: Malaria in early life

Malaria infections are harmful to both the pregnant mother and the developing fetus. Malaria is associated with a 3–4 times increased risk of miscarriage and a substantially increased risk of stillbirth, and it disproportionately affects children younger than 5 years. Falciparum malaria is responsible for more than 200 000 child deaths per year in Africa and vivax malaria causes excess mortality in children in Asia and Oceania. In a duet of papers, we review 1) the deleterious effects of malaria in pregnancy on the developing fetus and 2) the current strategies for prevention and treatment of malaria in children.

Paper 1 is “Deleterious effects of malaria in pregnancy on the developing fetus: a review on prevention and treatment with antimalarial drugs” by Makoto Saito, Valérie Briand, Aung Myat Min, and Rose McGready. The authors are concerned that one in ten maternal deaths in malaria endemic countries may result from Plasmodium falciparum infection, that malaria is associated with a 3–4 times increased risk of miscarriage and a substantially increased risk of stillbirth. While current treatment and prevention strategies reduce, but do not eliminate, malaria’s damaging effects on pregnancy outcomes. They conclude that there is a need for alternative strategies to prevent malaria in pregnancy.

Paper 2 is “Treatment and prevention of malaria in children” by Elizabeth A Ashley and Jeanne Rini Poespoprodjo. They examine the following interventions: Triple antimalarial combination therapies, the RTS,S/AS01 vaccine, seasonal malaria chemoprevention and preventing relapse in Plasmodium vivax infection with primaquine.
