Abstract Human population movements currently challenge malaria elimination in low transmission foci the Greater Mekong Subregion. Using a mixed-methods design, combining ethnography (n = 410 interviews), malariometric data 4996) and surveys 824 indigenous populations; n 704 Khmer migrants) vulnerability among different types of mobile populations was researched remote province Ratanakiri, Cambodia. Different structural human mobility were identified, showing differential risk vulnerability....
Malaria control along the Vietnam–Cambodia border presents a challenge for both countries' malaria elimination targets as region is forested, inhabited by ethnic minority populations, and potentially characterized early outdoor transmission. A mixed methods study assessed vulnerability to among Jarai population living on sides of in provinces Ratanakiri (Cambodia) Gia Lai (Vietnam). qualitative generated preliminary hypotheses that were quantified two surveys, one targeting youth ( N = 498)...
Annual mass drug administration with praziquantel has reduced schistosomiasis transmission in some highly endemic areas, but areas persistent high endemicity have been identified across sub-Saharan Africa, including Uganda. In these many children are rapidly reinfected post treatment, while remain uninfected or low-intensity infections. The aim of this mixed-methods study was to better understand variation water contact locations, behaviours and infection risk school-aged within an area...
In the Netherlands, sexually transmitted infection (STI) care is provided by general practitioners (GPs) as well specialised STI centres. Consultations at centres are monitored extensively, but data from practice limited. This study aimed to examine consultations in practice.Prospective observational patient survey.General practices within nationally representative Dutch Sentinel GP network (n=125 000 population), 2008-2011.GPs were asked fill out a questionnaire each consultation addressing...
An outbreak of isoniazid-resistant tuberculosis first identified in London has now been ongoing for 20 years, making it the largest drug-resistant documented to date worldwide. We culture-confirmed cases with indistinguishable molecular strain types and extracted demographic, clinical, microbiological social risk factor data from surveillance systems. summarised changes over time used kernel-density estimation k-function analysis assess geographic clustering. From 1995 2014, 508 were...
Background The World Health Organization identified Uganda as one of the 10 highly endemic countries for schistosomiasis. Annual mass drug administration (MDA) with praziquantel has led to a decline in intensity Schistosoma mansoni infections several areas. However, hotspots high (re)infection rates remain, additional research on risk factors and implementing interventions complement MDA are required further reduce disease burden these settings. Through mixed-methods study we aimed gain...
In December 2013, Public Health England (PHE) observed an increase in the number of cases Shigella sonnei linked to Orthodox Jewish Community (OJC). Ultimately, 52 S. phage type (PT) P and PT7 were notified between November 2013 July 2014. Whole-genome sequencing (WGS) was performed on a HiSeq 2500 platform (Illumina) isolates submitted PHE during investigation. Quality trimmed sequence reads mapped reference genome using BWA-MEM, single-nucleotide polymorphisms (SNPs) identified GATK2....
<h3>Objectives</h3> To determine time to linkage HIV care following diagnosis and identify risk factors for delayed linkage. <h3>Methods</h3> Patients newly diagnosed with at sexually transmitted infections (STI) clinics in the Netherlands were followed until care. Data collected of first consultation care, including demographics, behavioural information, CD4+ counts viral load (VL) measurements. Delayed was defined as >4 weeks between consultation. <h3>Results</h3> 310 participants...
Abstract Established methods of recruiting population controls for case–control studies to investigate gastrointestinal disease outbreaks can be time consuming, resulting in delays identifying the source or vehicle infection. After an initial evaluation using online market research panel members as a study Salmonella outbreak 2013, this method was applied four further UK between 2014 and 2016. We used data from all five interviews with each control team provider review operational issues,...
Abstract Background During the first wave of influenza A(H1N1)pdm09 pandemic in England 2009, morbidity and mortality were higher patients South Asian (Indian, Pakistani or Bangladeshi) ethnic minority groups. Objectives This study aims to provide insights representation this group among reported cases, indicating susceptibility exposure. Methods All laboratory‐confirmed cases including basic demographic limited clinical information that FluZone surveillance system between April October 2009...
In England, several recent campylobacter outbreaks have been associated with poultry liver consumption. Following a lunch event in hotel Surrey November 2013 where chicken parfait was served, guests reported having gastrointestinal symptoms. A retrospective cohort study showed 46 of 138 became unwell, median incubation period two days and for 11 cases infection laboratory confirmed. Food item analysis identified an association between illness consumption roast turkey (aOR=3.02 p=0.041) or...
Priorities for leprosy research are discussed frequently, but the variety of sources funding, and choices priorities by funding organizations, not well known. To address these matters, a survey was conducted 16 NGOs known to support research. The offices CEO each NGO were asked report total amount their from 2017–2021. They also indicate which five priority categories they supported, as defined Global Partnership Zero Leprosy Research Initiative. results presented at 21st International...
