Parasite Biology for Malaria Eradication

This session built upon the learnings of the “The Biology of Malaria” pre-course video lecture. Participants engaged in an active discussion of the biological implications of malaria eradication, including critical biological features of the parasite and current knowledge gaps. Key discussion topics included parasite biology (e.g., cell biology, parasite genetics, the biochemistry of the parasite, red cell interaction, drug action, and resistance mechanisms), malaria epidemiology, and parasite-vector relationships.

Learning Objectives:

  1. To understand the biology, life cycle-basis for this disease, and global public health aspects of malaria, including methods of measurement, the magnitude of the problem, and consequences of the disease on the population.
  2. To understand the incidence and distribution of infection and disease in human populations, determinants of frequency and distribution.

Lessons Learned from Other Disease Eradication Efforts

History has provided us with only one successful eradication attempt against a human disease: smallpox. However, polio and Guinea worm (dracunculiasis) appear very close to eradication. While there are significant biological, ecological, clinical and epidemiological differences between malaria and these three other diseases, the social and political challenges are more similar and history should be used, in part, to guide future eradication efforts. In this session, we will review some of the global lessons learned from previous and current eradication attempts that have come to embody the eradication zeitgeist. But we will also deploy a slightly different lens on the lessons learned by reviewing histories of elimination in specific countries that we suspect will be critical for malaria eradication. After an opening presentation, the class will be divided into nine groups of six-seven students each. Each will be given one of three attached papers from which to draw novel lessons learned on national eliminations during a global eradication campaign.

Learning Objectives:

  1. Identify key social or political factors responsible for elimination successes at the national level
  2. Contrast the approaches to smallpox eradication in India and the Democratic Republic of Congo.
  3. Recognize that there are lessons to be learned within as well as across nations.
course faculty
12:00–1:00PM
Diagnostics for Malaria Elimination

The tools and tactics required for active infection detection to support malaria elimination are different than those that have been successful for passive case detection in malaria control. This session will provide participants to propose solutions for diagnostics for elimination – then to refine those solutions through recognition of the differences between active and passive case detection; the definition of the unique diagnostic needs and product gaps for elimination/active infection detection; the translation of those needs to biomarker and product requirements; an analysis of existing tools against those requirements and an understanding of the current product pipeline.

Learning Objectives:

  1. To identify gaps with existing diagnostics for elimination needs.
  2. To provide an understanding of the diagnostic product development perspective/ process, including Target Product Profile (TPP) development and new diagnostic products to support malaria elimination.
  3. To provide an overview of the unique needs associated with correctly identifying the asymptomatic reservoir.
  4. To provide an overview of existing diagnostic product strengths and limitations, products in the development pipeline, and “what to expect” in the next five years.

Learning Objectives:

  1. Understand the concept of surveillance as an intervention and how this leads to tailored surveillance response-approaches/systems in different transmission/ elimination settings.
  2. Distinguish the surveillance-response approaches that are based on the minimum essential data collected in space and time to the traditional concept of monitoring and elimination where generally maximally possible data are collected.
course faculty
2:00–3:00PM
Prevention of Re-establishment and Certification for Malaria-free Status

After countries have eliminated malaria, they must implement strategies to prevent reestablishment of the infection. Over the years, many countries have interrupted transmission or come very close to malaria elimination only to see the disease resurge once specific prevention measures were removed. Certification of malaria elimination is the official recognition of malaria-free status granted by the World Health Organization. Certification reflects two conditions: that the country or overseas territory has interrupted indigenous human malaria transmission, and that the country has had an adequate system to prevent its re-establishment.

This session will provide an overview of key principles and health systems requirements of prevention of re-establishment and the criteria and procedures for certification of malaria elimination. Participants will then be divided into groups, provided with different case studies and asked either to a) outline the critical components of the country’s plan for prevention of reestablishment, or b) act as the certification evaluation team and highlight aspects of the programme that will need to be verified during a mission.

Learning Objectives:

  1. Define receptivity, risk of importation, malariogenic potential and the re-establishment of malaria and the key components of a plan to prevent re-establishment.
  2. Understand the criteria and procedure for certification of malaria elimination.
course faculty
3:00–4:00PM

This round table intends to tackle the issue of malaria control in settings with complex emergencies and particular operational difficulties. These situations are still found widely in malaria-endemic countries and have the potential to disrupt malaria control efforts.

Future Vector Control Tools & Resistance Management
  1. Despite novel insecticides rotated on existing delivery platforms and the development of new insecticide delivery platforms, we will still face the challenges of transmission outside of village settings and ongoing challenges of coverage and adherence. An integrated R&D approach to prevention of transmission is exploring tools with longer duration of action than existing products, tools that expand coverage to

non-traditional species or affect vector competence. These include extra-long-lasting indoor residual spraying (IRS), bednets with antimalarials, human and cattle endectocides and modified insect populations (i.e., genetic modification). After an overview, we’ll have a facilitated group discussion.

Learning Objectives:

  1. To identify key product attributes for long-term R&D solutions to the prevention of transmission for
  2. To describe how an endectocide works and its application to malaria vector control.
  3. To define the biological control challenges with the release of a genetically modified insect, and the additional challenges imposed with the use of a gene drive.

Financing Malaria Elimination

While great progress has been made in the effort to achieve elimination, and eventually eradication, of malaria, significant challenges remain. External financing is threatened. The recent uptick in malaria deaths and cases in certain countries and the focus on many external funders on low-income countries has heightened existing tensions between directing financing to high burden/high impact areas and/or low burden/”shrinking the map” counties. The session will include a short presentation followed by interactive engagement on some of the key questions and potential solutions related to financing for malaria including the urgent need for increased domestic financing.

Learning Objectives:

  1. To understand the global malaria financing
  2. To understand the balance and tension in external financing for high burden/high impact and low burden/shrinking the map approaches.
  3. To understand the importance of increased domestic finance

Partnering to Eliminate Malaria in Zambia

This session was an active case study discussion (based on the required reading of the case study) that built on the “Political Analysis for Malaria” pre-course video lecture. Participants analyzed the challenges confronting Zambia’s National Malaria Control Centre (MNCC) in collaboration with PATH’s Malaria Control and Elimination Partnership in Africa (MACEPA) project in Zambia in preparing to scale up malaria elimination activities. The discussion focused on how the MNCC responds to positive results from a Mass Drug Administration (MDA) study in the Southern Province of Zambia and the implications for national malaria policy.

How can the MNCC coordinate both state and non-state actors (including international non-governmental organizations, national non-governmental organizations, community- and faith-based organizations, donor agencies, traditional authorities, regional coordinating bodies, and academic institutions) in moving forward the government’s elimination targets and strategies?

Learning Objectives:

  1. To analyze the landscape of both non-state and state actors in reaction to the results of the MDA study.
  2. To assess the position and power of non-state and state actors regarding the MNCC’s efforts to move towards malaria elimination.

Methods for Improving Community Engagement
Chair: Elizabeth Fox; Panelists: Elizabeth Chizema Kawesha, and Franco Massimo Giovanni Pagnoni

Community engagement for malaria eradication – can we make it a science? Community engagement approaches to support communities to take actions to address their most pressing issues. Engaging and mobilizing communities is one of the four pillars of the Global Vector Control Response 2017–2030. The session will present research on community engagement in the crucial last mile of disease control and eradication from polio and Ebola. It will examine the current lack of evidence on impact and standards, best practices, and indicators for community engagement interventions and the efforts underway at UNICEF and World Health Organization (WHO) to bring more “science” to the field through standards, evidence review, and the WHO Guidelines development process.

The panel will discuss the attempt to capture and measure the contributions of community engagement to malaria elimination from recent research on the enhanced intervention package in Southern Province Zambia. It will explore potential community engagement actions and behaviors missing from efforts to decrease deaths from severe malaria at the community level. The discussion will center of how to raise the bar for performance, standards, and indicators for community engagement in national malaria control programs and to move beyond process indicators to effectively measure impact and results.

Learning Objectives:

  1. To understand the latest developments in community engagement standards, evidence review, indicator development, and WHO guidelines
  2. To apply concepts of community engagement standards to malaria control programs
  3. To assess different possible indicators and measures for community engagement interventions for malaria control.
course faculty
3:00–4:00PM

The lessons learned from smallpox and polio eradication initiatives are that innovation and evidence-based strategies on how to use tools – whether they are vaccines, diagnostics, drug or combination strategies – requires the engagement of innovators, from the bench to the field, throughout the life of the program. This also plays out in malaria. The core interventions in use today were implemented after 2000, and scale-up was facilitated by the new Global Fund for AIDS, TB, and Malaria. The predictable emergence of resistance to commonly used tools, the range of epidemiologic scenarios in which impact needs to be achieved, and the increasingly nuanced need to target the intervention package for efficiency and to maximize impact, together with drive the need for an innovation agenda. In addition, malaria can be invigorated by entirely new approaches to treatment and prevention.

A broad array of malaria partners is focused on innovation for malaria. In this session, participants will hear the latest strategy of the Bill & Melinda Gates Foundation; as well as consider the lessons learned from the Pasteur Institute. In addition, they will learn about a database of active projects that reflects the diversity of research in the malaria field, with multiple applications.

Learning Objectives:

  1. To consider the role of research in targeting solutions to the biggest challenges that impede progress against
  2. To analyze how priorities can be determined for research programs
  3. To review the Malaria Eradication Scientific Alliance (MESA) track database and explore research being undertaken in case study countries, so as to formulate different priorities in the context of national challenges.

Malaria Elimination in the Context of Political Instability and Climate Change

This session was an active case study discussion that builds upon the “Social, Cultural, Behavioral, and Environmental Determinants of Malaria” pre-course lecture. As countries plan for malaria elimination, political instability can impose major barriers for the uptake of important control strategies and for the sustainability of achieved gains. Similarly, environmental factors (natural environment: e.g., climate and land cover, and/or human-made environment: e.g., housing conditions and land use), which historically were the target of control interventions, may play a particularly important role for the achievement of elimination. This session discussed how these factors may affect elimination goals, and how countries should anticipate and plan ahead in order to mitigate the challenges that political and environmental factors impose.

Learning Objectives:

  1. To identify important factors related to political instability and climate change that affect the pattern and the level of local malaria transmission, and then may impose barriers for malaria elimination.
  2. Discuss the feasibility of social and environmental interventions as strategies for current efforts of malaria elimination.
