High levels of storage iron may increase malaria susceptibility. This risk has not been investigated in semi-immune adolescents. We investigated whether baseline iron status of nonpregnant adolescent girls living in a high malaria transmission area in Burkina Faso affected malaria risk during the fo...llowing rainy season. For this prospective study, we analysed data from an interim safety survey, conducted six months into a randomised iron supplementation trial. We used logistic regression to model the risk of P. falciparum infection prevalence by microscopy, the pre-specified interim safety outcome, in relation to iron status, nutritional indicators and menarche assessed at recruitment.

Interim guidance. 12 May 2021. The Continuity of essential health services: Facility Assessment Tool can be used by countries to rapidly assess the capacity of health facilities to maintain the provision of essential health services during the COVID-19 pandemic. It can help to alert the authorities ...and other stakeholders about where service delivery and utilization may require modification and/or investment. This assessment tool covers the following aspects of essential health services:
health workforce (numbers, absences, COVID-19 infections, health workforce management, training and support);
financial management and barriers;
service delivery and utilization (facility closures, changes in service delivery, community communication campaigns, changes in service utilization and catch-up strategies);
IPC capacities (protocols, safety measures, guidelines and the availability of personal protective equipment (PPE) for staff);
availability of therapeutics, diagnostics and supplies, and vaccine readiness; and
provision of COVID-19 primary care services.

The Zambia Population Based HIV impact assessment of 2016, reported the prevalence of viral hepatitis in Zambia as ranging between 5.6% among adults aged 15 to 59% in the general population, and 7.1% among HIV infected individuals. It is estimated that the majority of persons with chronic hepatitis ...B and/ or hepatitis C are unware of their infection and do not benefit from promotive, preventive and curative services designed to reduce onward transmission. Zambia introduced hepatitis B virus vaccine to the routine Under 5 vaccination schedule in 2005. Preliminary results from the ZAMPHIA indicate that hundreds of infections have been abated in children since then. However, its also clear that we continue to miss key opportunities to prevent transmission, diagnose and treat infections, prevent serious disease, and in many cases cure people. In addition, high risk groups inter alia health care workers still have limited access to the vaccine.

The guide is organized into the major types of toxicities, the associated symp-toms, possible offending medications, and the suggested nursing assessments and interventions. Some symptoms (e.g. nausea) may be associated with a num-ber of underlying causes and may be mild, or a symptom of... a more serious medical situation requiring urgent attention. The pathophysiology for medica-tion-related fatigue and hypersalivation are unclear and these symptoms are not grouped under a specific type of toxicity. Additional information (comments) are provided for each toxicity to highlight relevant clinical information that may assist in management of side effects. Medications more strongly associated with the side effect appear in bold text. The appendices include tools nurses can use to more thoroughly assess patient complaints of pain, depression and neuropathy.

La méningite est mortelle et débilitante ; elle frappe brutalement ; elle a de graves conséquences sanitaires, économiques et sociales et touche tous les âges de la vie dans tous les pays du monde. La méningite bactérienne peut être à l’origine d’épidémies, entraîner la mort dans les... 24 heures et un patient sur cinq peut rester handicapé à vie à la suite d’une infection. La plupart des cas et des décès dus à la méningite pourraient être évités par la vaccination mais les progrès obtenus pour la vaincre sont bien moins rapides que ceux réalisés contre d’autres maladies à prévention vaccinale.

Contact tracing for COVID-19 is the process of identifying, assessing, and managing people who have been exposed to someone who has been infected with the SARS-CoV-2 virus, while quarantine is the separation of contacts from other people after exposure to a probable or confirmed case of SARS-CoV-2 i...nfection. In the context of growing global population immunity from COVID-19 vaccination and past SARS-CoV-2 infection, WHO recommends that identification, contact, quarantine and follow-up should be prioritized for individuals at high risk who have been in contact with a confirmed or probable case of SARS-CoV-2 infection, rather than targeting all contacts. This updated guidance also introduces shorter recommended quarantine periods, including the ability to further shorten quarantine through the use of testing. National and local health authorities should use risk-based approaches to contact tracing and quarantine that include reviewing and adjusting to their local circumstances and disease epidemiology, population immunity, their health system’s capacities, and risk tolerance.

The Lancet Planetary Health Volume 5, ISSUE 7, e466-e478, July 01, 2021
Transmission of many infectious diseases depends on interactions between humans, animals, and the environment. Incorporating these complex processes in transmission dynamic models can help inform policy and disease control int...erventions. We identified 20 diseases involving environmentally persistent pathogens (ie, pathogens that survive for more than 48 h in the environment and can cause subsequent human infections), of which indirect transmission can occur from animals to humans via the environment.

Las infecciones del sitio quirúrgico (ISQ) constituyen una de las Infecciones Asociadas al Cuidado de la Salud (IACS) más frecuentes que ponen en riesgo a los pacientes llevando muchas veces al fracaso del procedimiento quirúrgico. Con una incidencia mucho mayor en países de medianos y bajos ing...resos, representa un desafío de la práctica médica cotidiana que compromete la salud y la seguridad de los pacientes. La indicación de profilaxis primaria con antibióticos en relación a los procedimientos invasivos, tiene como objetivo disminuir la incidencia de infecciones con la consecuente disminución de la morbimortalidad debiendo utilizarse únicamente en aquellos procedimientos en los que hay evidencia de efectividad. Cabe destacar que la indicación inadecuada, tiene potenciales efectos adversos tales como infecciones por Clostridium difficile, emergencia de resistencia
bacteriana, reacciones adversas a drogas e incremento de los costos en salud.
La profilaxis antibiótica como complemento de una buena técnica quirúrgica, es una medida costo efectiva de prevención de las ISQ representando alrededor del 30% de la indicación de antibióticos entre los pacientes hospitalizados. Dado que en algunos estudios el uso inapropiado de antibióticos se ve reflejado en el 40 al
80% de las indicaciones médicas, desde la Comisión de Infecciones Asociadas al Cuidado de la Salud y Seguridad del Paciente de SADI hemos realizado una actualización de la evidencia disponible. Este documento es una acción complementaria al consenso “Prevención de Infección del Sitio Quirúrgico” realizado entre SADI y el Instituto Nacional de Epidemiología “J. Jara” durante el Congreso de SADI 2015.
La posibilidad de contar con una guía actualizada de profilaxis quirúrgica adaptada a nuestro medio, constituye una herramienta de uso cotidiano por parte de los profesionales del equipo quirúrgico que permite la optimización de la utilización de fármacos restringiendo así la emergencia y diseminación de la resistencia bacteriana. Sin duda esperamos que pueda ser de utilidad para el equipo de salud.

Antimicrobial resistance (AMR) is a threat to global health and development and it contributes to millions of deaths worldwide each year. Inappropriate use and overuse of antibiotics are driving an increase in AMR and have a detrimental impact on the effectiveness of these critical medicines. Throug...h the Global Action Plan on AMR, WHO is working to improve the surveillance of antimicrobial resistance and reduce inappropriate antibiotic consumption.
There is a recognized need for high-quality resources to improve antibiotic prescribing globally. To address this need, a pragmatic approach was taken by WHO to develop actionable guidance for empiric antibiotic use.
The WHO AWaRe (Access, Watch, Reserve) antibiotic book provides concise, evidence-based guidance on the choice of antibiotic, dose, route of administration, and duration of treatment for more than 30 of the most common clinical infections in children and adults in both primary health care and hospital settings. The information included in the book supports the recommendations for antibiotics listed on the WHO Model Lists of Essential Medicines and Essential Medicines Children and the WHO AWaRe classification of antibiotics.
The WHO AWaRe antibiotic book is accompanied by summary infographics for each infection for both adults and children that provide a quick-reference guide for health care workers at the point of care.

Over the past twenty years, huge efforts made by a broad coalition of stakeholders curbed the last epidemic and brought the disease to the brink of elimination. In this paper, the latest figures on disease occurrence, geographical distribution and control activities are presented. Strong evidence in...dicates that the elimination of sleeping sickness ‘as a public health problem’ by 2020 is well within reach. In particular, fewer than one thousand new cases were reported in 2018, and the area where the risk of infection is estimated as moderate, high or very high has shrunk to less than 200,000 km2. More than half of this area is in the Democratic Republic of the Congo. The interruption of transmission of the gambiense form, targeted by the World Health Organization (WHO) for 2030, will require renewed efforts to tackle a range of expected and unexpected challenges. The rhodesiense form of the disease represents a small part of the overall HAT burden. For this form, the problem of under detection is on the rise and, because of an important animal reservoir, the elimination of disease transmission is not envisioned at this stage.

Malgré les progrès récents vers la mise au point d’un traitement hautement efficace et abordable contre le virus de l’hépatite C, beaucoup de personnes infectées par ce virus ne connaissent pas leur statut. L’Organisation mondiale de la Santé (OMS) estime qu’en 2019, 58 millions ...de personnes à travers le monde étaient atteintes d’une infection chronique par le virus de l’hépatite C, et qu’à peine 21 % d’entre elles avaient été diagnostiquées. Le défaut de sensibilisation, l’accès limité aux services de dépistage et de traitement, la stigmatisation, la discrimination et d’autres obstacles structurels contribuent au faible taux d’utilisation des services de dépistage du virus de l’hépatite C.
