Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

Community Based Rehabilitation for Children with Disabilities: Good Practices and Lessons from Save the Children Norway Ethiopia Programme Intervention
The framework is to be used as a reference guide, applied according to local priorities and needs, and targeted at academic institutions, educators, accreditation bodies, regulatory agencies and other users. The ultimate aim is to ensure that all health workers are equipped with the requisite compet...encies at pre-service education and in-service training levels to address AMR in policy and practice settings.

The development of water, sanitation and hygiene (WASH) in schools guidelines for TimorLeste is a landmark moment in our quest to make every school child-friendly – a place where every child can learn, play and grow with pride and dignity. The overarching goal is to improve health, boost education... achievement and promote gender equity in our schools.
The guidelines set clear levels of acceptable standards for water supply, provision of sanitation facilities and hygiene promotion in schools and provide a common framework and policy direction for all sub-sector actors. Therefore, all implementing agencies, managers, planners, architects, water and sanitation technicians, teaching staff, school directors, school boards, district WASH committees, local authorities and other relevant bodies should consult these guidelines, when making implementation plans.

This toolkit consists of eight modules which have been prepared as stand-alone documents that can be read by themselves, but they have also been prepared to complement one another. It has been designed as a tool for health professionals and students in the health care and public health sectors who ...want to engage more directly on the issue of climate change as educators with their patients, peers and communities, and/or as advocates for the policies, programs and practices needed to mitigate climate change and/or prepare for climate change in their workplaces and communities

Laboratory Biossafety Manual
This document provides guidance on the application of non-pharmaceutical countermeasures to minimise the spread of the 2019 novel coronavirus (2019-nCoV) in the population. Some of the measures proposed refer specifically to certain phases of the epidemic (containment or mitigation phases), and can ...be adapted depending on the assessed severity/impact of the infection. Other measures are valid for all phases of an epidemic.
The guidance is based on the current knowledge of the 2019-nCoV and evidence available on other viral respiratory pathogens, mainly the Severe Acute Respiratory Syndrome coronavirus (SARS-CoV), the Middle East Respiratory Syndrome-related coronavirus (MERS-CoV) and seasonal or pandemic influenza viruses.

Background Unrest in Chile over inequalities has underscored the need to improve public hospitals. Nursing has been overlooked as a solution to quality and access concerns, and nurse staffing is poor by international standards. Using Chile’s new diagnosis-related groups system and surveys of nurse...s and patients, we provide information to policy makers on feasibility, net costs, and estimated improved outcomes associated with increasing nursing resources in public hospitals.

Antimicrobial resistance (AMR) has emerged as a major public health concern, around which the international leadership has come together to form strategic partnerships and action plans. The main driving force behind the emergence of AMR is selection pressure created due to consumption of antibiotics.... Consumption of antibiotics in human as well as animal sectors are driven by a complex interplay of determinants, many of which are typical to the local settings.

Although Shiga toxin-producing Escherichia coli (STEC) have been isolated from a variety of food production animals, they are most commonly associated with ruminants from which we derive meat and milk. Because of the widespread and diverse nature of ruminant-derived food production, coupled with the... near ubiquity of STEC worldwide, there is no single definitive solution for controlling STEC that will work alone or in all situations. Instead, the introduction of multiple interventions applied in sequence, as a “multiple-hurdle scheme” at several points throughout the food chain (including processing, transport and handling) will be most effective.
This report summarizes the review and evaluation of interventions applied for the control of STEC in cattle, raw beef and raw milk and raw milk cheese manufactured from cows’ milk, and also evaluates available evidence for other small ruminants, swine and other animals. The information is presented from primary production, to the end of processing, providing the reader with information on the currently available interventions based on the latest scientific evidence.
This work was undertaken to support the development of guidelines for the control of STEC in beef, raw milk and cheese produced from raw milk by the Codex Committee on Food Hygiene (CCFH).

Chagas disease is currently endemic and also predicted to be at increased transmission risk under future climate change scenarios. Similarly, an expansion of areas in the United States at increased risk for Chagas disease transmission is also expected over the next several decades under climate chan...ge scenarios. Of particular interest is the predicted northern shift of triatomine species to central regions of the United States with historically unsuitable climates for T. cruzi vectors. The weight of evidence regarding the influences climate change may pose on T. cruzi vector species distributions demonstrates the sensitivity of Chagas disease transmission to future climate variability. In order to advance forecasts for the impact climate change may have on Chagas disease transmission in the Americas, it is imperative to
further develop, utilize, and perhaps combine predictive species distribution modeling approaches that integrate accurate, long term data on climate variables, vector species distributions, Chagas disease incidence, as well as other socio-ecological variables.

Presentation on WASH in Malawi
This guide presents a basis for understanding how diarrhoeal diseases are currently influenced by climate and weather, and may be further exacerbated by climate change. It is a technical guide on how to conduct a Vulnerability & Adaptation assessment for diarrhoeal diseases and climate change, and p...rovides guidance on how to:
identify populations and regions vulnerable to diarrhoeal diseases and the reasons for their vulnerability;
establish relevant baselines that can be analysed and monitored;
conduct analyses to project how diarrhoeal diseases may be impacted in the future due to climate change; and
identify appropriate responses to mitigate and monitor these risks over time.
