BackgroundDengue fever is a rapidly emerging infection throughout the tropics and subtropics with extensive public health burden. Adequate training of healthcare providers is crucial to reducing infection incidence through patient education and collaboration with public health authorities. We examined how public sector healthcare providers in a dengue-endemic region of Ecuador view and manage dengue infections, with a focus on the 2009 World Health Organization (WHO) Dengue Guidelines.MethodsA 37-item questionnaire of dengue knowledge, attitudes, and practices was developed and administered to dengue healthcare providers in Machala, Ecuador. Survey focus areas included: “Demographics,” “Infection and Prevention of Dengue,” “Dengue Diagnosis and the WHO Dengue Guide,” “Laboratory Testing,” “Treatment of Dengue,” and “Opinions Regarding Dengue.”ResultsA total of 76 healthcare providers participated in this study, of which 82 % were medical doctors and 14 % were nurses. Fifty-eight percent of healthcare professionals practiced in ambulatory clinics and 34 % worked in a hospital. Eighty-nine percent of respondents were familiar with the 2009 WHO Dengue Guidelines, and, within that group, 97 % reported that the WHO Dengue Guide was helpful in dengue diagnosis and clinical management. Knowledge gaps identified included Aedes aegypti mosquito feeding habits and dengue epidemiology. Individuals with greater dengue-related knowledge were more likely to consider dengue a major health problem. Only 22 % of respondents correctly reported that patients with comorbidities and dengue without warning signs require hospital admission, and 25 % of providers reported never admitting patients with dengue to the hospital. Twenty percent of providers reported rarely (≤25 % of cases) obtaining laboratory confirmation of dengue infection. Providers reported patient presumptive self-medication as an ongoing problem. Thirty-one percent of healthcare providers reported inadequate access to resources needed to diagnose and treat dengue.ConclusionParticipants demonstrated a high level of knowledge of dengue symptoms and treatment, but additional training regarding prevention, diagnosis, and admission criteria is needed. Interventions should not only focus on increasing knowledge, but also encourage review of the WHO Dengue Guidelines, avoidance of presumptive self-medication, and recognition of dengue as a major health problem. This study provided an assessment tool that effectively captured healthcare providers’ knowledge and identified critical gaps in practice.Electronic supplementary materialThe online version of this article (doi:10.1186/s40794-016-0024-y) contains supplementary material, which is available to authorized users.

Metagenomic next-generation sequencing (mNGS) is a novel tool for identifying microbial DNA and/or RNA in blood and other clinical specimens. In the face of increasingly complex patients and an ever-growing list of known potential pathogens, mNGS has been proposed as a breakthrough tool for unbiased pathogen identification. Studies have begun to explore the clinical applicability of mNGS in a variety of settings, including endocarditis, pneumonia, febrile neutropenia, osteoarticular infections, and returning travelers. The real-world impact of mNGS has also been assessed through retrospective studies, documenting varying degrees of success and limitations. In this review, we will explore current highlights of the clinical mNGS literature, with a focus on pediatric data where available. We aim to provide the reader with a deeper understanding of the strengths and weaknesses of mNGS and to provide direction toward areas requiring further research.
