The TPP process brought to the forefront the importance of linking use case, program platform and diagnostic performance characteristics when defining required criteria for diagnostic tools.
The clinical trial results reinforce the importance of hygiene practices in lymphedema management. The positive outcomes in both patient groups likely resulted from repeated training and close attention to local hygiene—emphasizing the importance of such management in the care of LE patients.
After years of hard work and international cooperation, the onchocerciasis elimination programs of Brazil and Venezuela have confined river blindness to the smallest area yet in the Amazon Rainforest. The achievement comes despite the disruption caused by the COVID-19 pandemic.
This study aims to provide health workers with quantitative tools to assess what treatment strategies are best applied in given epidemiological settings.
Researchers have found that treating school-aged children periodically with praziquantel has decreased the prevalence of schistosomiasis (bilharzia) in sub-Saharan Africa by almost 60% during the past 20 years.
This study revealed a 37.13% prevalence of Schistosoma mansoni infection among children. This is an alert to improve and implement appropriate control strategies such as mass drug administration in Ethiopia.
In conclusion, the prevalence of S. haematobium infection in the study participants was remarkably high. However, further studies, including large sample size will be essential to assess the burden of the disease in the study area.
Collectively, this study demonstrates that pyrazoline derivatives are promising scaffolds in the discovery of novel antischistosomal agents.
The parasitic worm that causes the neglected tropical disease, schistosomiasis, has daily rhythms in gene expression, including genes that could be targeted in drug development.
The result is a point-of-care test strip, not unlike a pregnancy test, that carries recombinant versions of the chosen proteins, and can detect even low-intensity schistosomiasis infections.
Our results show that S. mansoni is highly endemic and a major health concern in Ituri province, DRC. Infection prevalence and intensity, and the prevailing socioeconomic, environmental, and behavioural risk factors in Ituri reflect intense exposure and alarming transmission rates.
Treatment with ivermectin–albendazole resulted in higher efficacy against trichuriasis than albendazole alone in Laos and Pemba Island but not in Côte d'Ivoire. We recommend implementation of this combination therapy for soil-transmitted helminth control in countries with high T trichiura prevalence and proven enhanced efficacy of this treatment, particularly where ivermectin is beneficial against other endemic helminthiases.
By accounting for and exploiting spatial correlation in the prevalence data, we achieved remarkably improved precision of prevalence estimates compared with the traditional approach. The geostatistical approach also delivers predictions for unsampled evaluation units that are geographically close to sampled evaluation units.
Dengue, Chikungunya, and Zika viruses have all been recorded in Mexico; however, recent diagnostic advances have improved the accuracy of serological testing. A study publishing December 2nd in PLOS Neglected Tropical Diseases by José Esteban Muñoz-Medina at the Mexican Institute of Social Security, Mexico, and colleagues suggests that current estimates of the incidence of arboviruses in Mexico may have been previously underestimated.
Ruth and Bishnu from TLM Nepal are responsible for supporting persons affected by leprosy with their mental wellbeing, both in the community and at Anandaban Hospital. Here they share some of the lessons they’ve learnt from the frontline of mental health care for persons affected by leprosy.
The Leprosy Research Initiative (LRI) is pleased to announce a call for proposals for funding commencing in 2023. LRI funds research with a focus on leprosy – including research applications combining leprosy with other neglected tropical diseases (NTDs) or other diseases that share cross-cutting issues with leprosy.
Health leaders of the Togo Ministry of Health, Public Hygiene and Universal Access to Care Togo Ministry of Health, along with program officials from the ministries of economy and finance, education, agriculture, and youth and partner organizations gathered in Lomé on November 11th to launch and disseminate the country’s Neglected Tropical Diseases (NTDs) sustainability plan.
