Online Short Course: Essential Medicines, Commodities and Supplies

Essential Medicines, Commodities and Supplies Needed for Community Level Primary Health Care Interventions is our 2-credit online course offered from 5-9 June 2023 as part of the Global Health Systems Summer Institute. Please check the syllabus and share with colleagues.

Course Description” Essential commodities are among the 8 basic primary health care services and the 6 health systems building blocks as defined by the World Health Organization

Primary health care programs in low and middle-income countries require essential health commodities be made available at the community level. Logistic systems need to be developed to ensure that commodities are adequately estimated and delivered. In addition, systems for safely maintaining and monitoring stocks are needed at the community level.

The Summer Institute offers a variety of short-term courses in a variety of global health areas between 5-30 June 2023. The Global Health Systems Summer Institute provides early- and mid-career public health professionals with cutting-edge skills in a variety of global health topics. The Institute is also a great opportunity for part-time MPH and other Hopkins students and fellows to learn a valuable set of skills in an in-demand and rapidly growing field of public health.

Malaria News Today 2020-09-22: covering three continents

Today’s stories cover three continents including Surveillance for imported malaria in Sri Lanka, community perceptions in Colombia and Annual Fluctuations in Malaria Transmission Intensity in 5 sub-Saharan countries. In addition there is an overview of microscopy standards and an Integrated Macroeconomic Epidemiological Demographic Model to aid in planning malaria elimination. We also see how COVID-19 is disturbing Seasonal Malaria Chemoprevention activities in Burkina Faso. Read more by following the links in the sections below.

Will More of the Same Achieve Malaria Elimination?

Results from an Integrated Macroeconomic Epidemiological Demographic Model. Historic levels of funding have reduced the global burden of malaria in recent years. Questions remain, however, as to whether scaling up interventions, in parallel with economic growth, has made malaria elimination more likely today than previously. The consequences of “trying but failing” to eliminate malaria are also uncertain. Reduced malaria exposure decreases the acquisition of semi-immunity during childhood, a necessary phase of the immunological transition that occurs on the pathway to malaria elimination. During this transitional period, the risk of malaria resurgence increases as proportionately more individuals across all age-groups are less able to manage infections by immune response alone. We developed a robust model that integrates the effects of malaria transmission, demography, and macroeconomics in the context of Plasmodium falciparum malaria within a hyperendemic environment.

The authors analyzed the potential for existing interventions, alongside economic development, to achieve malaria elimination. Simulation results indicate that a 2% increase in future economic growth will increase the US$5.1 billion cumulative economic burden of malaria in Ghana to US$7.2 billion, although increasing regional insecticide-treated net coverage rates by 25% will lower malaria reproduction numbers by just 9%, reduce population-wide morbidity by ?0.1%, and reduce prevalence from 54% to 46% by 2034. As scaling up current malaria control tools, combined with economic growth, will be insufficient to interrupt malaria transmission in Ghana, high levels of malaria control should be maintained and investment in research and development should be increased to maintain the gains of the past decade and to minimize the risk of resurgence, as transmission drops. © The American Society of Tropical Medicine and Hygiene [open-access]

Microscopy standards to harmonise methods for malaria clinical research studies

Research Malaria Microscopy Standards (ReMMS) applicable to malaria clinical research studies have been published in Malaria Journal. The paper describes the rationale for proposed standards to prepare, stain and examine blood films for malaria parasites. The standards complement the methods manual(link is external) previously published by the World Health Organization and UNICEF/UNDP/World Bank/WHO Special Programme for Research and Training in Tropical Diseases (TDR). The standards aim to promote consistency and comparability of data from microscopy performed for malaria research and hence to strengthen evidence for improvements in malaria prevention, diagnostics and treatment.

Microscopy is important in both malaria diagnosis and research. It is used to differentiate between Plasmodium species and stages and to estimate parasite density in the blood – an important determinant of the severity of disease. It is also used to monitor the effectiveness of drugs based on the rate at which parasites recrudesce or are cleared from the blood.

While rapid diagnostic tests have replaced microscopy in some contexts, microscopy remains an essential tool to support clinical diagnosis and research. The standardisation of methods allows direct comparisons from studies conducted across different points in time and location. This facilitates individual participant data meta-analyses, recognised as the gold standard approach to generate evidence for improvements in interventions and hence patient outcomes.

Estimating Annual Fluctuations in Malaria Transmission Intensity and in the Use of Malaria Control Interventions in Five Sub-Saharan African Countries

RTS,S/AS01E malaria vaccine safety, effectiveness, and impact will be assessed in pre- and post-vaccine introduction studies, comparing the occurrence of malaria cases and adverse events in vaccinated versus unvaccinated children. Because those comparisons may be confounded by potential year-to-year fluctuations in malaria transmission intensity and malaria control intervention usage, the latter should be carefully monitored to adequately adjust the analyses. This observational cross-sectional study is assessing Plasmodium falciparum parasite prevalence (PfPR) and malaria control intervention usage over nine annual surveys performed at peak parasite transmission. Plasmodium falciparum parasite prevalence was measured by microscopy and nucleic acid amplification test (quantitative PCR) in parallel in all participants, and defined as the proportion of infected participants among participants tested. Results of surveys 1 (S1) and 2 (S2), conducted in five sub-Saharan African countries, including some participating in the Malaria Vaccine Implementation Programme (MVIP), are reported herein; 4,208 and 4,199 children were, respectively, included in the analyses.

Plasmodium falciparum parasite prevalence estimated using microscopy varied between study sites in both surveys, with the lowest prevalence in Senegalese sites and the highest in Burkina Faso. In sites located in the MVIP areas (Kintampo and Kombewa), PfPR in children aged 6 months to 4 years ranged from 24.8% to 27.3%, depending on the study site and the survey. Overall, 89.5% and 86.4% of children used a bednet in S1 and S2, of whom 68.7% and 77.9% used impregnated bednets. No major difference was observed between the two surveys in terms of PfPR or use of malaria control interventions. © The American Society of Tropical Medicine and Hygiene [open-access]

Community perception of malaria in a vulnerable municipality in the Colombian Pacific

Malaria primarily affects populations living in poor socioeconomic conditions, with limited access to basic services, deteriorating environmental conditions, and barriers to accessing health services. Control programmes are designed without participation from the communities involved, ignoring local knowledge and sociopolitical and cultural dynamics surrounding their main health problems, which implies imposing decontextualized control measures that reduce coverage and the impact of interventions. The objective of this study was to determine the community perception of malaria in the municipality of Olaya Herrera in the Colombian Pacific.

A 41-question survey on knowledge, attitudes, and practices (KAP) related to malaria, the perception of actions by the Department of Health, and access to the health services network was conducted. In spite of the knowledge about malaria and the efforts of the Department of Health to prevent it, the community actions do not seem to be consistent with this knowledge, as the number of cases of malaria is still high in the area.

Use of a Plasmodium vivax genetic barcode for genomic surveillance and parasite tracking in Sri Lanka

Sri Lanka was certified as a malaria-free nation in 2016; however, imported malaria cases continue to be reported. Evidence-based information on the genetic structure/diversity of the parasite populations is useful to understand the population history, assess the trends in transmission patterns, as well as to predict threatening phenotypes that may be introduced and spread in parasite populations disrupting elimination programmes. This study used a previously developed Plasmodium vivax single nucleotide polymorphism (SNP) barcode to evaluate the population dynamics of P. vivax parasite isolates from Sri Lanka and to assess the ability of the SNP barcode for tracking the parasites to its origin.

A total of 51 P. vivax samples collected during 2005–2011, mainly from three provinces of the country, were genotyped for 40 previously identified P. vivax SNPs using a high-resolution melting (HRM), single-nucleotide barcode method. The proportion of multi-clone infections was significantly higher in isolates collected during an infection outbreak in year 2007. Plasmodium vivax parasite isolates collected during a disease outbreak in year 2007 were more genetically diverse compared to those collected from other years. In-silico analysis using the 40 SNP barcode is a useful tool to track the origin of an isolate of uncertain origin, especially to differentiate indigenous from imported cases. However, an extended barcode with more SNPs may be needed to distinguish highly clonal populations within the country.

Coronavirus rumours and regulations mar Burkina Faso’s malaria fight

By Sam Mednick, Thomson Reuters Foundation: MOAGA, Burkina Faso – Health worker Estelle Sanon would hold the 18-month-old and administer the SMC dose herself, but because of coronavirus she has to keep a distance from her patients. “If I am standing and watching the mother do it, it’s as if I’m not doing my work,” said Sanon, a community health volunteer assisting in a seasonal campaign to protect children in the West African country from the deadly mosquito-borne disease.

Burkina Faso is one of the 10 worst malaria-affected nations in the world, accounting for 3% of the estimated 405,000 malaria deaths globally in 2018, according to the World Health Organization (WHO). More than two-thirds of victims are children under five. Now there are fears malaria cases could rise in Burkina Faso as restrictions due to coronavirus slow down a mass treatment campaign and rumours over the virus causing parents to hide their children, according to health workers and aid officials.

“COVID-19 has the potential to worsen Burkina Faso’s malaria burden,” said Donald Brooks, head of the U.S. aid group Initiative: Eau, who has worked on several public health campaigns in the country.  “If preventative campaigns can’t be thoroughly carried out and if people are too scared to come to health centres … it could certainly increase the number of severe cases and the risk of poor outcomes.”

During peak malaria season, from July to November, community health workers deploy across Burkina Faso to treat children with seasonal malaria chemoprevention (SMC). This is the second year the campaign will cover the whole country with more than 50,000 volunteers going door-to-door, said Gauthier Tougri, coordinator for the country’s anti-malaria programme. Logistics were already challenging. Violence linked to jihadists and local militias has forced more than one million people to flee their homes, shuttered health clinics and made large swathes of land inaccessible. Now the coronavirus has made the task even harder, health workers said.

People in Cape Verde evolved better malaria resistance in 550 years

Yes, we are still evolving. And one of the strongest examples of recent evolution in people has been found on the Cape Verde islands in the Atlantic, where a gene variant conferring a form of malaria resistance has become more common.

Portuguese voyagers settled the uninhabited islands in 1462, bringing slaves from Africa with them. Most of the archipelago’s half a million inhabitants are descended from these peoples. Most people of West African origin have a variant in a gene called DARC that protects.

Deadly malaria and cholera outbreaks grow amongst refugees as COVID pandemic strains health systems.

Apart from the strain on health facilities during the pandemic, in some countries such as Somalia, Kenya and Sierra Leone, we are seeing that a fear of exposure to COVID-19 has prevented parents from taking their children to hospital, delaying diagnosis and treatment of malaria and increasing preventable deaths. COVID restrictions in some countries have also meant pregnant women have missed antimalarial drugs. Untreated malaria in pregnant women can increase the risk of anaemia, premature births, low birth weight and infant death. According to the World Health Organization (WHO), 80% of programs designed to fight HIV, tuberculosis and malaria have been disrupted due to the pandemic and 46% of 68 countries report experiencing disruptions in the treatment and diagnosis of malaria.

A Mothers’ Day Wish: Lifesaving Maternal, Newborn and Child Health Supplies

Eyelachew Desta shares thoughts as a guest blogger in time for Mothers’ Day. Concern is expressed  about ensuring increased access for low cost essential lifesaving Maternal newborn and child health supplies in Ethiopia. This posting appeared originally at Social & Cultural Basis for Community and Primary Health Programs. Can you imagine? At this time of Mother’s Day celebration, there are thousands of  women living in low income country , unlucky to be a mother to enjoy the celebration of mother’s day because of preventable  birth complications due to lack of  accesses to  essential   low cost medicines and  commodities necessary for maternal, Child and New born Health. One of these low-income countries is Ethiopia where maternal and child mortality is still high. According to an analysis published by Reproductive Health Supplies Coalition (RHSC), a quarter of all deaths between 2009 and 2013  occurred in Ethiopia are maternal mortality. This study indicated  “postpartum hemorrhage (PPH)— uncontrolled bleeding after childbirth—and preeclampsia/eclampsia (PP/E)- a condition which causes high blood pressure and seizures during pregnancy”, among others, are the two leading causes of maternal deaths in Ethiopia ,could be treated by low cost and effective  medicines, Oxytocin and Misoprostol.

The availability of accessible, reliable and low cost essential maternal health commodities is indispensable to address maternal and child mortality in Ethiopia. However according to an assessment  study conducted in Ethiopia, there are gaps in the supply chain management of commodities for maternal, neonatal, and child health. According to this study one of these gaps is  “The supply chain system for MNCH commodities is inconsistent and has not been integrated into the Integrated Pharmaceutical Logistics System (IPLS)” of Ethiopia. Further the study indicated that family planning, HIV, tuberculosis, and malaria have been included in this IPLS, but not MNCH commodities. This study also identified that  there is a lack of common understanding at lower level of the health system about the national policy and protocols  as well as its implementation to provide MNCH services and commodities free of charge at primary health care units. To address these gaps, there is a need of immediate actions as well as strong commitment among all stakeholders involved and engaged in the funding, monitoring, regulating and administering the logistic supply of MNCH commodities in Ethiopia. The Federal Ministry of Health (FMOH) should develop a strategy to provide continues education and training at all levels of the health system about its policy of provision of MNCH services and commodities free of charge at primary health care units , ensure policy protocols are implemented properly. In addition to these the FMOH should strengthen its monitoring system to identify gaps in the implementation of the MNCH services and commodities policy and take measures to narrow those gaps. The Ethiopia Pharmaceuticals Fund and Supply Agency should revise its Integrated Pharmaceutical Logistics System (IPLS) to insure MNCH commodities are integrated in the system by 2020. Ultimately international donors like USAID needs to continue and strengthen their financial and technical support to the overall MNCH program of Ethiopia .
