Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

The "Global NCD action plan" provides a road map and a menu of policy options for countries to take in order to attain the 9 voluntary global targets, including that of a 25% relative reduction in premature mortality from cardiovascular diseases, cancer, diabetes or chronic respiratory diseases by 2...025. The main focus of this action plan is on 4 types of NCDs (cardiovascular diseases, cancer, chronic respiratory diseases, diabetes) which make the largest contribution to morbidity and mortality due to NCDs, and on 4 shared behavioural risk factors (tobacco use, unhealthy diet, physical inactivity, harmful use of alcohol).

In this course you will examine the interconnections between poverty, development and violent conflict. This is one of seven Medical Peace Work courses.
NEUROLOGY ATLAS presents for the first time, the most
comprehensive collection and compilation of information on
neurological resources across 109 countries. The results confirm
that the available resources including services for neurological
disorders are markedly insufficient; in addition, the...re are large
inequities across regions and income groups of countries.
Urgent action is required to enhance the resources available
to address the increasing burden of neurological disorders.

Non-Communicable Diseases (NCDs), including mental disorders, currently pose one of the biggest threats to health and development globally, particularly in low and middle income countries2. It is predicted that unless proven interventions are rapidly implemented in countries, in the short to medium ...term, health care costs will increase exponentially and severe negative consequences will ensue not only to individuals and families but to whole societies and economies. NCDs are already a major burden in South Africa, but without added rigorous and timely action the health and development consequences may well become catastrophic. Immediate and additional, high quality, evidence based and focussed interventions are needed to promote health, prevent disease and provide more effective and equitable care and treatment for people living with NCDs at all levels of the health system. The problem is further compounded by the rising global prevalence of multi-morbidity (defined as the coexistence of two or more chronic diseases in one individual).

The Infection prevention and control in the context of coronavirus disease 2019 (COVID-19): a living guideline consolidates technical guidance developed and published during the COVID-19 pandemic into evidence-informed recommendations for infection prevention and control (IPC). This living guideline... is available both online and PDF.
**This version of the living guideline (version 5.0) **includes the following seven revised statements for the prevention, identification and management of SARS-CoV-2 infections among health and care workers:
a good practice statement on national and subnational testing strategies;
a good practice statement on passive syndromic surveillance of health and care workers;
a good practice statement on prioritizing health and care workers for SARS-CoV-2 testing;
a good practice statement on protocols for reporting and managing health and care worker exposures;
a good practice statement to limit in-person work of health and care workers with active SARS-CoV-2 infections;
a statement on high-risk exposures and quarantine; and,
a conditional recommendation on the duration of isolation for health and care workers.
Understanding the updated section
Prevention of infections in the health care setting includes a multi-pronged and multi-factorial approach that includes IPC and occupational health and safety measures and adherence to Public Health and Social Measures in the community by the health workforce. The underlying infection prevention and control strategy of this section is the notion that early identification of symptomatic cases, testing and quarantining/isolating health and care workers decreases the risk of nosocomial infection to patients and to other health and care workers.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

This document focuses on making recommendations for the diagnosis and treatment of Chagas disease, an infection caused by Trypanosoma cruzi, the protozoan agent of a systemic parasitic disease. Methodology: These clinical practice guidelines were prepared following the WHO handbook for guideline dev...elopment (5). A multidisciplinary development group was formed, comprised of thematic experts, epidemiologists, methodologists, and users. Since there were no existing guidelines that could be adapted, the guidelines were developed from scratch.

This manual presents a compelling case for action on carbapenem-resistant organisms (CROs) and describes the linkages between the prevention and control of CROs and the Global Action Plan on Antimicrobial Resistance (AMR). It describes how the eight recommendations contained within the World Health ...Organization (WHO) guidelines for the prevention and control of carbapenem-resistant Enterobacteriaceae, Acinetobacter baumannii and Pseudomonas aeruginosa in health care facilities relate to general measures (that is, the core components of infection prevention and control [IPC] programmes) that need to be in place in all countries and health care facilities to prevent and control health care-associated infections (HAIs). The use of a stepwise approach is proposed to support implementation and improvement, based on the evidence and experience of what has worked in several health care settings worldwide. The focus is on adoptable and adaptable information.

'We did a systematic review of 172 observational studies in health-...care and non-health-care settings across 16 countries and six continents... Physical distancing of 1 m or more was associated with a much lower risk of infection, as was use of face masks (including N95 respirators or similar and surgical or similar masks [eg, 12–16-layer cotton or gauze masks]) and eye protection (eg, goggles or face shields)...'
