New! CWW systematic review of global soil-transmitted helminthiasis prevalence and intensity studies

CWW is pleased to share a systematic literature review1 titled, “Qualitative systematic literature review of global soil-transmitted helminthiasis prevalence and intensity studies.” The literature review was undertaken to assess the availability and quality of STH data starting from 2006, when several STH endemic countries began implementing mass drug administration for STH control.

The literature review included 209 studies published between 2006 and 2018 that fit the inclusion criteria. Findings from the literature review indicated that the available STH epidemiological data are “fragmented, mostly of questionable quality, and minimally useful for regional or global program decisions.” The authors recommend a standardized approach to gathering STH program data, based on a comprehensive global monitoring and evaluation framework that will allow for pooling of information across countries and regions to guide global policy and progress.

New paper co-authored by CWW team member on strengthening the NTD Supply Chain through partnerships

new paper1 published in PLOS NTDs describes the complex supply chain systems necessary for the delivery of preventive chemotherapy for neglected tropical diseases (NTD) interventions. The paper notes that the supply chains established to support NTD operations are complex and that the Coronavirus Disease 2019 (COVID-19) pandemic has further highlighted the need for strong supply chains for health system strengthening.

Cassandra Holloway, Children Without Worms (CWW) Program Support Specialist, is an author on this publication and CWW is one of the 17 partner organizations that make up the NTD Supply Chain Forum.

CWW supports the NTD Supply Chain Forum, a public-private partnership whose vision is to support endemic countries in controlling and eliminating NTDs. As the host of the Forum, CWW helped develop and pilot the NTDeliver database mentioned extensively in this recent publication.

Children Without Worms (CWW) hosts the Neglected Tropical Diseases (NTD) Supply Chain Forum (SCF) meeting

CWW hosted the second of the bi-annual meetings of the NTD SCF in September 2020. Participants included representatives from national Ministries of Health, the WHO, implementing partner organizations, and pharmaceutical donors such as Merck Healthcare KGaA, Merck Sharp & Dohme Corp., J&J, GSK, Eisai,  and Pfizer. (Access meeting report here.)

Spread over the course of three days via a virtual platform, the meeting included updates from representatives of pharmaceutical donors and the various working groups set up to solve supply chain management challenges in delivering pharmaceutical products to endemic countries.

Attendees participate in the virtual meeting


The supply chain forum was particularly relevant this year, as CWW encouraged dialogue and creative solutions to COVID-19 challenges. Participants identified that with the reduction of flights, border closures and restrictions, the delivery of NTD medications has posed many challenges. Further, mass drug administrations (MDA) have decreased because of COVID-19 restrictions such as school closures. Participants noted that missed MDAs may also trigger the need for an additional MDA in 2021 to keep the programs on track.

To overcome such challenges, NTD SCF participants proposed concise measures for ensuring the delivery of medicines to affected communities. Several recommendations were made at the end of the three-day meeting, including next steps to guide the future of the NTD SCF.

The next virtual forum meeting is scheduled for February 23-24, 2021.

New study led by STH Advisory Committee members with contributions from CWW on STH Diagnostics

new paper1 published in PLOS NTDs demonstrates the feasibility and challenges of an international external quality assessment scheme (EQAS) to test and ensure the quality of molecular diagnostic testing for parasitic worms such as soil-transmitted intestinal worms.

Facilitated by Children Without Worms (CWW), the study piloted an international EQAS for the diagnosis of parasitic worms involving 15 laboratories in Africa, Asia, Australia, Europe, and North America. Findings showed that while most laboratories performed well, some laboratories may need to improve their test protocol.

Commenting on the findings, Rubina Imtiaz, CWW Director, said, “this timely publication highlights the development of  molecular testing methodology (qPCR) for STH and additional parasites. It also draws attention to the need for standardizing testing approaches across laboratories around the world so that test results are comparable. Findings from this study serve as an important first step in that direction.”

As a regular contributor to STH policy  and a leader in innovation, CWW continues to advocate for investments in STH diagnostics and works with key stakeholders such as the World Health Organization and the STH Advisory Committee and others to promote a “use-case focused” collaboration on NTD diagnostics.

All Hands on Deck: A synchronized approach to fighting COVID-19

In a new paper published in the International Journal of Infectious Diseases, Rubina Imtiaz, MBBS, CWW Director, and other global public health experts called for a unified response to the coronavirus pandemic. Calling it an ‘all-hands-on-deck’ approach, the experts proposed a list of tools and institutional mechanisms to advance the unified approach. The publication drew on experiences from previous epidemic outbreaks like the Ebola outbreaks and the successes of multilateral platforms like the NTD Supply Chain Forum, facilitated by CWW, to form a global, COVID-19 mitigation framework with tools for a collaborative pandemic response. Reflecting on the role of institutions, the authors offered the following example:

“[T]he Task Force for Global Health convened a virtual meeting across 46 global entities representing pharmaceutical commodity donors, implementing partners and shippers, under WHO leadership to assess and respond to anticipated interruptions in critical supply chain of deworming drugs. This rapid consultation across multilaterals and private sector entities helped rapidly access existing platforms such as the DHL Control Tower for Humanitarian Supply Chain to assist the movement of medical supplies and other essential drugs from China to the rest of the world.” (Ebrahim, Zhou, et al. 2020).

Dr. Imtiaz added that “examples like the NTD Supply Chain Forum, facilitated by CWW, show us the importance of a multilateral approach in mitigating global, public health crises by helping to rapidly adapt existing and new platforms and mechanisms for a response. During a global crisis like COVID-19, our response should not be the sole responsibility of one sector, but the responsibility of all sectors to work together.”

CWW has also been working with partners to assess delays to deworming, and other NTD campaigns. CWW is supporting national deworming programs to focus on those activities that can continue during the pandemic per WHO interim guidelines on community- and facility-based care.

Announcing the Launch of CWW’s New Website

CWW is excited to announce the launch of our newly designed website!

As a leader in STH policy, innovation, and advocacy, CWW needs to make news and resources about global STH control and elimination efforts easily accessible to current and new partners and colleagues. We believe our new website does just that – the new site is more user-friendly, faster, and easier to navigate. It provides better access to information on the STH Advisory Committee and STH resources produced by CWW.

New features on our website include an image gallery via Flickr that provides quick access to photos related to CWW’s work around the world. Our social media channel on Twitter is now integrated onto our homepage so visitors can view our engagement on social media.

A featured resources section on the home page provides visitors easy access to our latest resources. These resources include tools to estimate disease prevalence, such as the Integrated Community-Based Survey for Program Monitoring, and the Global M&E Framework, a resource document for deworming programs to make data-driven decisions on deworming interventions.

The new website also features our STH Advisory Committee members. The STH Advisory Committee is an expert group of research and national program leaders with expertise in public health, diagnostics, epidemiology, child, and school health. The STH Advisory Committee comes together once a year at an annual meeting to assess global accomplishments and persistent needs and gaps towards the WHO STH goals. The committee provides relevant technical and scientific advice on STH control to donors, researchers, pharmaceutical companies, and non-governmental and governmental implementers.

We expect to add new content regularly to our new website, so we encourage STH and NTD partners to bookmark our pages.

Many thanks to Resonance Marketing for building the new site for CWW!

New CWW publication provides deworming program with evidence to adjust Mass Drug Administration

new paper1 published in the BMC Public Health shows that population-based disease mapping surveys such as the Integrated Community-Based Survey for Program Monitoring (ICSPM) can support monitoring for mature deworming programs that have delivered Soil-Transmitted Helminth (STH) interventions for five or more years. The paper resulted from Children Without Worms’ long-standing partnership with the Ministry of Health and Family Welfare (MOHFW), Bangladesh, to provide robust data to its Lymphatic Filariasis and STH Program to assess progress towards eliminating STH infections as a public health problem. After eight years of twice-annual mass drug administration (MDA) to school-aged children, the National Program surveyed four districts between August and October 2017 using ICSPM to determine the prevalence and intensity of STH. The ICSPM expands on the WHO’s guidelines for transmission assessment surveys for Lymphatic Filariasis (LF)2. The surveys revealed that the MDAs impacted STH prevalence in three of the four districts (3.4-5%), while it remained high in Sirajganj district (23.4-29.1%). As a result of these findings, the National Program is reviewing the frequency of MDA to adjust it in impacted areas and improve the quality and range of interventions in the persistent high-prevalence districts.

According to this paper, the ICSPM provides deworming programs with a new way to map STH (at baseline or impact).

Dr. Rubina Imtiaz, Director of Children Without Worms, and a co-author on this study said, “The study demonstrates that community-level parasitological data is necessary to understand the true impact of deworming interventions,” and that, ” the ICSPM provides National Programs with the kind of evidence needed to streamline resources to communities with high burden and scale back interventions in areas that have shown to have low burden.”

Since 2016, CWW has engaged with National STH Programs in Kenya and Sierra Leone to use the ICSPM for assessing progress in deworming interventions, as part of its broader strategy to build sustainable epidemiologic capacity for NTD program monitoring.

Continuing the War on Worms

“People, parasites, and poverty have a thriving relationship” said Vicente Y. Belizario, Jr., MD, MTM&H, and when it comes to intestinal worms, where Belizario has dedicated more than 30 years of his career, this is clearly evident. Intestinal worms are parasitic worms that cause soil-transmitted helminthiasis (STH), some of the most common infections in the world and the most commonly neglected tropical disease (NTD) that routinely affects poorer populations due to lack of quality sanitation and water infrastructures. Children Without Worms (CWW) works to control and eventually eliminate these infections, but it takes a collaborative effort of partnerships across the scientific and implementation sectors to get the job done, and Belizario has been an instrumental part of that collaborative effort. As a former STH Advisory Committee Chair and member, Belizario recently stepped down from the Committee to take on a new role as the Dean of the College of Public Health, University of the Philippines, Manila. In recognition of the contributions he has made to the STH community and as a partner to CWW, we catch up with him for some reflections on his time in the Committee and his thoughts on the current status and future of the War on Worms.

STH Advisory Committee meets in Liverpool, September 2019

The 2019 annual meeting of the STH Advisory Committee (STHAC) was held September 15-16, in Liverpool, UK. Dr. Jürg Utzinger, Professor and Director of the Swiss Tropical and Public Health Institute, chaired the proceedings. Meeting participants included STHAC members, STH leaders from the WHO, Johnson & Johnson, GSK, and invited speakers from the World Bank, the Bill & Melinda Gates Foundation, Lancaster University, DOLF, DeWorm3 project, and Evidence Action. Over two days, STHAC members reviewed STH updates on research, diagnostics, inclusion of strongyloidiasis in STH morbidity elimination, persisting data issues, and a formativediscussion on sustainability of NTD programs through thoughtful transition to national “ownership”.

Meeting  highlights included an initiation of a dialogue on sustainability in the NTD context, and what that means from the national program perspective. Discussions touched on the opportunities  to learn from previous efforts such as the African Program for Onchocerciasis Control (APOC). There was also a stated need to share tools and country engagement processes across major actors in this area for optimal coordination and to project STH (as the least “vertical” NTD) in all cross-NTD planning. Key outcomes of this year’s meeting will be detailed in a report to be shared in the coming months.

Additional highlights included a presentation on a new geospatial model for projecting sampling needs for STH and analysis of ESPEN data by Dr. Rachel Pullan (STHAC member) to show persistent mismatch between disease and intervention maps in Africa. This, and relateddiagnostic discussions led the STHAC to recommend that a follow-up meeting be organized to develop standard STH sampling methods that link to WHO indicator thresholds. These should incorporate existing diagnostics (Kato-Katz) but also be flexibly responsive to include future, more sensitive diagnostics as those become available (e.g. PCR methods). A second follow-up meeting shall be organized by the STHAC to further define the processes, evidence and metrics for including Strongyloidiasis in the WHO STH program.

These and other recommendations will soon be available in the meeting report posted on CWW’s website:

The STHAC welcomed Dr. Bruno Levecke, and Ms. Lisa Rotondo, as new members on the committee. Their addition will bring much-needed diagnostic, epidemiologic and implementation expertise to the STHAC.

The STHAC also recognized Dr. Vicente Belizario’s service to the STH community as he steps down to carry on full time, his role as the Dean of the College of Public Health, at the University of the Philippines, Manila. Dr. Belizario served as an STHAC member for over 6 years and was briefly the chair of the STHAC. He brought his extensive and valuable STH control and public health experience as a leading public health and NTD leader from the Philippines and WPRO, to the STHAC.

About the STH Advisory Committee:

The STHAC is an independent group of research and national program leaders with expertise in in public health, diagnostics, epidemiology, child and school health, who assess the global accomplishments and persistent needs/gaps towards the WHO STH goals and provide relevant technical and scientific advice on STH control to donors, researchers, pharmaceutical companies, and non-governmental and governmental implementers. CWW is the secretariat of the STHAC.
