In order to target resources and drugs to reach trachoma elimination targets by the year 2020, data on the burden of disease are required. Using prevalence data in African countries derived from the Global Atlas of Trachoma (GAT), the distribution of trachoma continues to be focused in East and West... Sub-Saharan Africa, North Africa and a few endemic countries in Central Sub-Saharan Africa. Currently, 129.4 million people are estimated to live in areas that are confirmed to be trachoma endemic and 98 million are known to require access to the SAFE strategy. The maps and information presented in this work highlight the GAT as important open-access planning and advocacy tool for efforts to finalize trachoma mapping and assist national programmes in planning interventions.

Esta guía está enfocada en emitir recomendaciones para el diagnóstico y el tratamiento de la enfermedad de Chagas, como infección por Trypanosoma cruzi, agente protozoario de una parasitosis sistémica. Metodología: La presente guía de práctica clínica fue confeccionada siguiendo los método...s de elaboración de guías de la OMS (5). De forma general, se conformó un grupo desarrollador multidisciplinario compuesto por expertos temáticos, epidemiólogos, metodólogos y usuarios. Dado que no se identificaron guías susceptibles de ser adaptadas, la guía se desarrolló de novo.

Scabies is a contagious skin condition caused by the mite Sarcoptes scabiei which burrows into the skin and causes severe itching. Scabies is transmitted by direct skin-to-skin contact or indirectly by contact with contaminated material (fomites). This condition is often challenging to diagnose as m...any patients may have only subtle symptoms. However, other patients may present with the classic history of exposure, severe pruritis that is worse at night, and reference to other individuals with similar symptoms. This activity reviews the evaluation and treatment of scabies and highlights the role of the interprofessional team in managing patients with this condition.

Scabies is an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominis). The microscopic scabies mite burrows into the upper layer of the skin where it lives and lays its eggs. The most common symptoms of scabies are intense itching and a pimple-like skin rash. The scabies mite... usually is spread by direct, prolonged, skin-to-skin contact with a person who has scabies.

Rabies is a fatal zoonotic disease most often transmitted to people via bites from infected dogs. This course provides a general introduction to rabies, and the One Health approach currently taken to prevent it. It consists of seven video-lectures, demonstration videos, and lessons learnt from peopl...e who work at the frontline of rabies elimination programmes around the world. It targets both a general audience and those who would like to learn more about rabies and the pathway to eliminating this disease – like prospective and current public health and animal health practitioners in rabies endemic countries.

Soil transmitted helminth (STH) infections are among the most common human infections worldwide with over 1 billion people affected. Many estimates of STH infection are often based on school-aged children (SAC). This study produced predictive risk-maps of STH on a more finite scale, estimated the nu...mber of people infected, and the amount of drug required for preventive chemotherapy (PC) in Ogun state, Nigeria. Georeferenced STH infection data obtained from a cross-sectional survey at 33 locations between July 2016 and November 2018, together with remotely-sensed environmental and socio-economic data were analyzed using Bayesian geostatistical modelling. Stepwise variable selection procedure was employed to select a parsimonious set of predictors to predict risk and spatial distribution of STH infections. The number of persons (pre-school ages children, SAC and adults) infected with STH were estimated, with the amount of tablets needed for preventive chemotherapy. An overall prevalence of 17.2% (95% CI 14.9, 19.5) was recorded for any STH infection. Ascaris lumbricoides infections was the most predominant, with an overall prevalence of 13.6% (95% CI 11.5, 15.7), while Hookworm and Trichuris trichiura had overall prevalence of 4.6% (95% CI 3.3, 5.9) and 1.7% (95% CI 0.9, 2.4), respectively. The model-based prevalence predictions ranged from 5.0 to 23.8% for Ascaris lumbricoides, from 2.0 to 14.5% for hookworms, and from 0.1 to 5.7% for Trichuris trichiura across the implementation units. The predictive maps revealed a spatial pattern of high risk in the central, western and on the border of Republic of Benin. The model identified soil pH, soil moisture and elevation as the main predictors of infection for A. lumbricoides, Hookworms and T. trichiura respectively. About 50% (10/20) of the implementation units require biannual rounds of mass drug administration. Approximately, a total of 1.1 million persons were infected and require 7.8 million doses. However, a sub-total of 375,374 SAC were estimated to be infected, requiring 2.7 million doses. Our predictive risk maps and estimated PC needs provide useful information for the elimination of STH, either for resource acquisition or identifying priority areas for delivery of interventions in Ogun State, Nigeria.

Soil-transmitted helminth (STH) infections are among the most common infections worldwide with an estimated 1.5 billion infected people or 24% of the world’s population. These infections affect the poorest and most deprived communities with poor access to clean water, sanitation and hygiene in tro...pical and subtropical areas, with the highest prevalence reported from sub-Saharan Africa, China, South America and Asia. They are transmitted by eggs present in human faeces, which in turn contaminate soil in areas where sanitation is poor. Over 260 million preschool-age children, 654 million school-age children,108 million adolescent girls and 138.8 million pregnant and lactating women live in areas where these parasites are intensively transmitted, and are in need of treatment and preventive interventions.

This facilitator’s manual is designed to support the implementation of the Dengue Clinical Management training course. The guide contains specific instructions for the facilitator and provides:
- a detailed description of the clinical course of dengue illness, which reflects the dynamic and sys...temic nature of dengue that has crucial bearing on the patient’s management;
- a detailed description of the basic pathophysiological changes of severe dengue (i.e. plasma leakage and hypovolaemia/shock) and guidance on the recognition of these changes and appropriate action of management;
- a brief discussion on WHO classification (1997) and its limitations;
- guidance on the differential diagnoses that can be confused with dengue or vice versa; they were described according to the stage of disease;
- a more focused guide on the disease monitoring in accordance with the dynamic changes as the disease progresses;
- emphasis on the importance of monitoring the plasma leakage (haemodynamic status of the patient, clinical signs of plasma leakage and haematocrit);
- a clearer algorithm for fluid management in cases of severe dengue; and
- emphasis on the importance of recognizing or suspecting significant occult bleed. Keep the facilitator’s manual with you each day as you prepare and deliver the information. Use it as a reference when delivering classroom presentations, but avoid reading directly from it during sessions.

The meeting addressed the last key area, that is, determining the best method or combination of diagnostic methods for a control programme for S. stercoralis infections in humans.
Dr Montresor’s presentation highlighted that while there is currently no “gold standard” for the... diagnosis of S. stercoralis, there is a felt urgency to optimize diagnostic regimens that are currently available, and in the context of population-based testing (as opposed to individual focused diagnostics in clinical settings).
In other words, the diagnostic test(s) should have good accuracy, but we should remember that in public health we do not aim at individual diagnosis: rather, we need a tool that should help to estimate the prevalence in a population.
