Lymphatic filariasis

A novel series of putative Brugia malayi histone demethylase inhibitors as potential anti-filarial drugs

Tamara Kreiss et al., PLOS Neglected Tropical Diseases

We have identified a novel series of compounds which appears to affect filarial parasite epigenetic regulatory mechanisms compromising parasite survival. These compounds provide both a pharmacological probe for the study of filarial parasite epigenetic mechanisms important for survival as well as providing a potential opportunity for anti-filarial drug development. In addition, these mechanisms are present in a variety of parasitic nematodes offering the opportunity for development of treatments for a wide variety of parasitic nematodes.

In conclusion, a high prevalence and incidence of epilepsy was observed in villages in Mundri. Urgent action is needed to prevent children from developing onchocerciasis-associated epilepsy by strengthening the local onchocerciasis-elimination programme.

The Long and Winding Road to Elimination

Lara Dahan, Global Institute for Disease Elimination

The development of an NTD Master Plan for Malawi is now well underway with expected delivery and dissemination expected in mid-2022. Thus far the learnings have been numerous, what started as a small-scale initiative to conduct transmission assessment in two districts has evolved into a multi-stakeholder process spanning across several development areas. I am particularly impressed by the adaptability resilience of program managers to manage uncertainty and the commitment of the partners to “leave no one” behind on the journey to elimination. If I’ve learned anything in my time working in global health it’s that successful elimination strategies are underpinned by the collaboration of passionate and committed individuals that make up disease elimination programs. 


Prevalence, intensity and endemicity of intestinal schistosomiasis and soil-transmitted helminthiasis and its associated factors among school-aged children in Southern Ethiopia

Zerihun Zerdo et al., Scientific Reports

This study was aimed to assess the prevalence of STH/SCH infections, the intensity of infections, and factors associated with STH infection among school-aged children (SAC) in Uba Debretsehay and Dara Mallo districts (previously not known to be endemic for SCH) in southern Ethiopia, October to December 2019.

A simple new screening tool for diagnosing imported schistosomiasis

Silvia Roure et al., Public Health in Practice

A two-component process consisting of a scored patient consultation questionnaire followed by serological assay can be a suitable strategy for screening populations at high risk of schistosomiasis infection.

The identification of alternative oxidase in intermediate host snails of Schistosoma and its potential role in protecting Oncomelania hupensis against niclosamide-induced stress

Ni Jiang et al., Parasites & Vectors

AOX [alternative oxidase] was found in all the snail intermediate hosts of Schistosoma examined here. AOX was significantly activated in O. hupensis under niclosamide-induced stress, which led to a reduction in oxidative stress in the snail. The inhibition of AOX activity in snails can dramatically enhance the molluscicidal effect of niclosamide. A potential target for the development of an environmentally safe snail control method, which acts by inhibiting the activity of AOX, was identified in this study.

Schistosomiasis and Hookworm: Eastern Uganda’s Neglected Tropical Diseases

Uma Paithankar and Holly Lam, Pulitzer Center

The main obstacles to eradicating these helminth infections are misconceptions about the transmission of these infections; a lack of access to resources, which increases risk of infection and reinfection; and the stigma surrounding them.

In a bid to improve the immunity of pupils and protect them from chronic illnesses caused by worms, Nigeria's federal government, through the Ministry of Humanitarian Affairs, Disaster Management and Social Development, said it would deworm at least ten m

Yi-Ting Yeh et al., PLOS Pathogens

Overall, our data on the mechanical interplay between host VECs [vascular endothelial cells] and the schistosome egg improve our understanding of how this parasite manipulates its immediate environment to maintain disease transmission.

Female Genital Schistosomiasis Lesions Explored Using Circulating Anodic Antigen as an Indicator for Live Schistosoma Worms

Takalani Girly Nemungadi et al., Frontiers in Tropical Diseases

Grainy sandy patches and abnormal blood vessels are found more commonly in women who harbour live Schistosoma haematobium worms whilst homogenous yellow patches may indicate chronic tissue damage due to dead ova.

Soil-Transmitted Helminthiasis

Prevalence of soil-transmitted helminths infections among preschool and school-age children in Ethiopia: a systematic review and meta-analysis

Legese Chelkeba et al., Global Health Research and Policy

Southern Nations Nationalities and Peoples Region, Amhara, and Oromia regions carry the highest-burden and are categorized to Moderate Risk Zones (MRZ) and therefore, requiring MDA once annually with Albendazole or Mebendazole. The prevalence of STHs decreased after MDA compared to before MDA, but the decline was not statistically significant.

FG To Deworm Ten Million Pupils Nationwide

In a bid to improve the immunity of pupils and protect them from chronic illnesses caused by worms, Nigeria's federal government, through the Ministry of Humanitarian Affairs, Disaster Management and Social Development, said it would deworm at least ten million pupils.


Anti-Trachoma School Clubs are a Game Changer in Ethiopia

Christian Blind Mission

The CBM funded Amhara Trachoma Control Programme (ATCP) working with partner ORDA (Organisation for Rehabilitation and Development in Amhara) has set up 319 Anti-Trachoma School Clubs - an initiative in which school children actively participate in behaviour change exercises that have helped their families and communities fight the spread of Trachoma – a disease caused by the bacteria infection known as Chlamydia trachomatis. 

New project launched to fight blindness

Sammy Lutta, Nation (Kenya)

The three-year project dubbed ‘Vision for Kenya: Improving Eye Health Through Stronger Systems’ that will jointly be implemented by The Fred Hollows Foundation and Turkana County government aims at combating avoidable blindness through treatment, surgeries and eye examinations. . . Turkana Health Executive Jane Ajele said the project covering all the seven sub-counties will boost county government’s effort to eliminate trachoma in Turkana West and Loima, which are high burden sub-counties.

Downstream impacts: How local access to clean water is improving the lives of women and girls


Operation Eyesight’s Zambian team rehabilitated a borehole located in the village of Kwanga, in Southern Zambia, in 2021. This rehabilitation has meant local access to an abundance of fresh water for the entire community. It’s one of 96 already drilled but non-functioning boreholes that the organization has rehabilitated in the past three years, along with the 106 boreholes drilled in Zambia’s Sinazongwe district, located in the country’s arid south.  This has helped eliminate trachoma from this district. Access to clean water has also brought a host of benefits across communities, including improved health outcomes, thriving local economies and increased opportunities for women and girls.
