Lymphatic filariasis
DOLF Team receives a $1.8 million Bill and Melinda Gates Foundation Grant to Explore Lymphatic Filariasis Elimination in Indonesia
As a result, the Ministry of Health is seeking to determine why LF returned and will conduct two more rounds of MDA in the fall of 2022 and 2023. For this resumed MDA, triple drug treatment with ivermectin combined with DEC and albendazole (IDA) will be used that was developed a few years ago by DOLF.
Safety and Tolerability of Ivermectin and Albendazole Mass Drug Administration in Lymphatic Filariasis Endemic Communities of Tanzania: A Cohort Event Monitoring Study
A chronic illness, or clinical manifestation of lymphatic filariasis, or being female or pre-existing clinical symptoms were independent significant predictors of AEs. IA combination preventive chemotherapy is safe and tolerable, and associated AEs are mild-to-moderate and transient, with few severe AEs. Safety monitoring during MDA campaigns in individuals with underlying clinical conditions is recommended for timely detection and management of AEs.
Mass drug administration for elimination of Lymphatic Filariasis
Waqainabete says with COVID19 restrictions now being lifted and good coverage of the COVID 19 vaccination rate, the Lymphatic Filariasis program has finally been able to roll out the second round of MDA in the coming days.
8% of world population at risk of filaria lives in UP
The drive will be launched virtually by deputy CM and health minister Brajesh Pathak on Thursday. Dr Singh said that 19 districts were being covered in the present round.
Mosquito Species To Be Listed As Restricted Animals
HONOLULU, Hawaiʻi -The State plans to introduce mosquitos containing the Wolbachia bacterium in order to reduce mosquito populations and thus "reduce the potential of transmission of mosquito vectored diseases.
Mass drug administration of ivermectin, diethylcarbamazine, plus albendazole compared with diethylcarbamazine plus albendazole for reduction of lymphatic filariasis endemicity in Papua New Guinea: a cluster-randomised trial
Mass administration of the triple-drug regimen was more effective than the two-drug regimen in reducing microfilariae prevalence in communities to less than the target level of 1%, but did not reduce circulating filarial antigen prevalence to less than 2%. These results support the use of mass drug administration with the triple-drug regimen to accelerate elimination of lymphatic filariasis.
Schistosomiasis
Unbalanced relationships: insights into the interaction between gut microbiota, geohelminths, and schistosomiasis
Thus, this work aimed to understand interactions between the microbiota and parasitic diseases caused by the most important geohelminths and schistosomiasis and the consequences of these associations.
Using choice modelling to identify popular and affordable alternative interventions for schistosomiasis in Uganda
We administered a discrete choice experiment to understand community preferences for interventions that would reduce individuals' risk of contracting, or transmitting, Schistosoma mansoni. These focused on water access, sanitation and hygiene (WASH) interventions. We compared interventions that target behaviours that mainly put oneself at higher risk versus behaviours that mainly put others at risk. We used two payment vehicles to quantify what individuals are willing to give up in time and/or labour for interventions to be implemented. Key findings indicate that new sources of potable water and fines on open defecation are the highest valued interventions.
The Road to Elimination: Current State of Schistosomiasis Research and Progress Towards the End Game
To date, control strategies have focused on effective diagnostics, mass drug administration, complementary and integrative public health interventions. Non-mammalian intermediate hosts and other vertebrates promote transmission of schistosomiasis and have been utilized as experimental model systems. Experimental animal models that recapitulate schistosomiasis immunology, disease progression, and pathology observed in humans are important in testing and validation of control interventions. We discuss the pivotal value of these models in contributing to elimination of schistosomiasis.
Soil-Transmitted Helminthiasis
The Use of MALDI-TOF MS as a Diagnostic Tool for Adult Trichuris Species
The use of matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry (MS) is increasing since the last decades due to its recent evidence as a potential role for reliable identification of microorganisms and a few nematodes. . .The results confirmed that MALDI-TOF MS was able to identify Trichuris species. Additionally, a MALDI-TOF MS profile of T. suis proteome was carried out to develop the first internal database of spectra for the diagnosis of trichuriasis and other Trichuris spp.
The first report on the prevalence of soil-transmitted helminth infections and associated risk factors among traditional pig farmers in Bali Province, Indonesia
The infections seen in farmers were distributed among hookworm, Ascaris spp., and Trichuris spp., at 15.1%, 9.2%, and 4.2%, respectively. The risk factors associated with infections of STH and Ascaris spp. were personal hygiene, home sanitation, education level, household income, and having a primary occupation as a traditional pig farmer. In contrast, personal hygiene, education level, and primary occupation were the only risk factors for hookworm infection, while personal hygiene and home sanitation were the risk factors associated with Trichuris spp. infection. The limitation of this study was that the number of samples was relatively small due to the difficulty of obtaining stool samples from traditional pig farmers, with many individuals refusing to provide their stool for inspection.
Prevalence of Intestinal Parasite Infections and Associated Factors among Pregnant Women in Northwest Ethiopia
Intestinal parasite infections remained a serious health burden to pregnant women in the study area with the dominance of a hematophagous worm (hookworm). Community-based intestinal parasite screening and treatment are essential to alleviate the burden caused by intestinal parasite infections.

Arboviral disease record data - Dengue and Chikungunya, Brazil, 2013–2020
The data presented in this work will assist researchers in investigating antecedents of arbovirus emergence and transmission more generally, and Dengue and Chikungunya in particular. Furthermore, it can be used to train and test machine learning models for differential diagnosis and multi-class classification.
Lobomycosis Epidemiology and Management: The Quest for a Cure for the Most Neglected of Neglected Tropical Diseases
An effective therapy for lobomycosis has been found following decades of research led by the State Dermatology Program of Acre in the Amazon rainforest, where the largest number of cases occur. This discovery opened new avenues for future studies. The main recommendations here, addressed to the Brazilian Ministry of Health, are for lobomycosis to become a reportable disease to ensure that disease prevalence is measured, and that it be prioritized such that affected individuals may access treatment free-of-charge.
