Data from: Distinguishing between reservoir exposure and human-to-human transmission for emerging pathogens using case onset data

Adam Kucharski, Harriet L. Mills, Amy Pinsent, Christophe Fraser, Maria Van Kerkhove, Christl A. Donnelly, Steven Riley & Harriet Mills
Pathogens such as MERS-CoV, influenza A/H5N1 and influenza A/H7N9 are currently generating sporadic clusters of spillover human cases from animal reservoirs. The lack of a clear human epidemic suggests that the basic reproductive number R0 is below or very close to one for all three infections. However, robust cluster-based estimates for low R0 values are still desirable so as to help prioritise scarce resources between different emerging infections and to detect significant changes between clusters...

Data from: The REporting of studies Conducted using Observational Routinely-collected health Data (RECORD) statement: methods for arriving at consensus and developing reporting guidelines

Stuart G. Nicholls, Pauline Quach, Erik Von Elm, Astrid Guttmann, David Moher, Irene Petersen, Henrik T. Sørensen, Liam Smeeth, Sinéad M. Langan & Eric I. Benchimol
Objective: Routinely collected health data, collected for administrative and clinical purposes, without specific a priori research questions, are increasingly used for observational, comparative effectiveness, health services research, and clinical trials. The rapid evolution and availability of routinely collected data for research has brought to light specific issues not addressed by existing reporting guidelines. The aim of the present project was to determine the priorities of stakeholders in order to guide the development of the REporting...

Data from: How do patients and health workers interact around malaria rapid diagnostic testing, and how are the tests experienced by patients in practice? A qualitative study in western Uganda

Robin Altaras, Anthony Nuwa, Bosco Agaba, Elizabeth Streat, James K. Tibenderana, Sandrine Martin & Clare E. Strachan
Background: Successful scale-up in the use of malaria rapid diagnostic tests (RDTs) requires that patients accept testing and treatment based on RDT results and that healthcare providers treat according to test results. Patient-provider communication is a key component of quality care, and leads to improved patient satisfaction, higher adherence to treatment and better health outcomes. Voiced or perceived patient expectations are also known to influence treatment decision-making among healthcare providers. While there has been a...

Data from: The impact of hotspot-targeted interventions on malaria transmission in Rachuonyo south district in the western Kenyan highlands: a cluster-randomized controlled trial

Teun Bousema, Gillian Stresman, Amrish Y. Baidjoe, John Bradley, Philip Knight, William Stone, Victor Osoti, Euniah Makori, Chrispin Owaga, Wycliffe Odongo, Pauline China, Shehu Shagari, Ogobara K. Doumbo, Robert W. Sauerwein, Simon Kariuki, Chris Drakeley, Jennifer Stevenson & Jonathan Cox
Background: Malaria transmission is highly heterogeneous, generating malaria hotspots that can fuel malaria transmission across a wider area. Targeting hotspots may represent an efficacious strategy for reducing malaria transmission. We determined the impact of interventions targeted to serologically defined malaria hotspots on malaria transmission both inside hotspots and in surrounding communities. Methods and Findings: Twenty-seven serologically defined malaria hotspots were detected in a survey conducted from 24 June to 31 July 2011 that included 17,503...

Background: Individuals living in malaria-endemic regions develop naturally acquired immunity against severe malarial disease, but it is unclear whether immunity that affects the establishment of infections develops following continuous natural exposure. Methods: We cleared schoolchildren in Burkina Faso of possible sub-patent infections and examined them weekly for incident infections by PCR. Plasma samples collected at enrolment were used to quantify antibodies to the pre-eryhrocytic-stage antigens circumsporozoite protein (CSP) and liver stage antigen. Sporozoite gliding inhibition...

Data from: Process evaluation of a national primary eye care programme in Rwanda

Jennifer L. Y. Yip, Tess Bright, Sebastian Ford, Wanjiku Mathenge & Hannah Faal
Background: Visual impairment is a global public health problem, with an estimated 285 million affected globally, of which 43% are due to refractive error. A lack of specialist eye care in low and middle-income countries indicates a new model of care would support a task-shifting model and address this urgent need. We describe the features and results of the process evaluation of a national primary eye care (PEC) programme in Rwanda. Methods: We used the...

Data from: Monogamy promotes altruistic sterility in insect societies

Nicholas G. Davies & Andy Gardner
Monogamy is associated with sibling-directed altruism in multiple animal taxa, including insects, birds, and mammals. Inclusive-fitness theory readily explains this pattern by identifying high relatedness as a promoter of altruism. In keeping with this prediction, monogamy should promote the evolution of voluntary sterility in insect societies if sterile workers make for better helpers. However, a recent mathematical population-genetics analysis failed to identify a consistent effect of monogamy on voluntary worker sterility. Here, we revisit that...

Teun Bousema, Elamaran Meibalan, Aissata Barry, Matthew Gibbins, Shehu Awandu, Lisette Meerstein-Kessel, Fiona Achar, Selina Bopp, Christopher Moxon, Amidou Diarra, Siaka Debe, Nicolas Ouedraogo, Ines Barry-Some, Emilie Badoum, Traore Fagnima, Kjerstin Lanke, Bronner Goncalves, John Bradley, Dyann Wirth, Chris Drakeley, Wamdaogo Guelbeogo, Alfred Tiono, Matthias Marti, Matthew P Gibbins, Fiona Achcar … & Alfred B Tiono
Background Plasmodium falciparum transmission depends on mature gametocytes that can be ingested by mosquitoes taking a blood meal on human skin. Although gametocyte skin sequestration has long been hypothesized as important contributor to efficient malaria transmission, this has never been formally tested. Methods In naturally infected gametocyte carriers from Burkina Faso, we assessed infectivity to mosquitoes by direct skin feeding and membrane feeding. We directly quantified male and female gametocytes and asexual parasites in finger-prick...
