Population movements have turned Chagas disease (CD) into a global public health problem. Despite the successful implementation of subregional initiatives to... control vectorial and transfusional Trypanosoma cruzi transmission in Latin American settings where the disease is endemic, congenital CD (cCD) remains a significant challenge. In countries where the disease is not endemic, vertical transmission plays a key role in CD expansion and is the main focus of its control. Although several health organizations provide general protocols for cCD control, its management in each geopolitical region depends on local authorities, which has resulted in a multitude of approaches. The aims of this review are to (i) describe the current global situation in CD management, with emphasis on congenital infection, and (ii) summarize the spectrum of available strategies, both official and unofficial, for cCD prevention and control in countries of endemicity and nonendemicity. From an economic point of view, the early detection and treatment of cCD are cost-effective. However, in countries where the disease is not endemic, national health policies for cCD control are nonexistent, and official regional protocols are scarce and restricted to Europe. Countries of endemicity have more protocols in place, but the implementation of diagnostic methods is hampered by economic constraints. Moreover, most protocols in both countries where the disease is endemic and those where it is not endemic have yet to incorporate recently developed technologies. The wide methodological diversity in cCD diagnostic algorithms reflects the lack of a consensus. This review may represent a first step toward the development of a common strategy, which will require the collaboration of health organizations, governments, and experts in the field.

These guidelines provide recommendations for the non-pharmacological aspects of infection prevention and control for acute respiratory diseases (AR...D) in health care. Administrative and infection controls, including early detection, isolation and reporting, and establishment of infection control infrastructure, are key components for containment and mitigation of the impact of pathogens that may constitute a major public health threat. In these guidelines, the options of using natural ventilation and/or exhaust fan assisted ventilation in health-care facilities (HCF) are considered.

Noncommunicable diseases (NCDs) such as cancer, cardiovascular disease, diabetes and chronic respiratory diseases and their risk factors are an inc...reasing public health and development challenge in Kazakhstan. This report provides evidence through three analyses that NCDs reduce economic output and discusses potential options in response, outlining details of their relative returns on investment. An economic burden analysis shows that economic losses from NCDs (direct and indirect costs) comprise 2.3 trillion tenge, equivalent to 4.5% of gross domestic product in 2017. An intervention costing analysis provides an estimate of the funding required to implement a set of policy interventions for prevention and clinical interventions. A cost–benefit analysis compares these implementation costs with the estimated health gains and identifies which policy packages would give the greatest returns on investment. For example, the salt policy package achieved a benefit-to-cost ratio of 118.4 over 15 years, a return of more than 118 tenge for every 1 tenge invested.

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 ... medbox">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 replacing 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).

The Infection prevention and control in the context of coronavirus disease 2019 (COVID-19): a living guideline consolidates technical guidance deve...loped 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.

22 April 2022, This document provides updated interim recommendations on the use of masks by health workers providing care to patients with suspected or confirmed COVID-19. This update is prompted by new evidence around mask use and COVID-19 transmi...ssion, as well as the emergence of variants of concern including Omicron. Masks continue to be a critical tool to prevent the spread of COVID-19. These interim guidelines supersede the recommendations provided in the WHO recommendations on mask use by health workers, in light of the Omicron variant of concern published on 22 December 2022.
WHO continually evaluates the emerging evidence and will review these interim recommendations within two months and issue new guidance as needed.

To guide One Health capacity building efforts in the Republic of Guinea in the wake of the 2014–2016 Ebola virus disease (EVD) outbreak, we sough...t to identify and assess the existing systems and structures for zoonotic disease detection and control. We partnered with the government ministries responsible for human, animal, and environmental health to identify a list of zoonotic diseases – rabies, anthrax, brucellosis, viral hemorrhagic fevers, trypanosomiasis and highly pathogenic avian influenza – as the country's top priorities. We used each priority disease as a case study to identify existing processes for prevention, surveillance, diagnosis, laboratory confirmation, reporting and response across the three ministries. Results were used to produce disease-specific systems “maps” emphasizing linkages across the systems, as well as opportunities for improvement. We identified brucellosis as a particularly neglected condition. Past efforts to build avian influenza capabilities, which had degraded substantially in less than a decade, highlighted the challenge of sustainability. We observed a keen interest across sectors to reinvigorate national rabies control, and given the regional and global support for One Health approaches to rabies elimination, rabies could serve as an ideal disease to test incipient One Health coordination mechanisms and procedures. Overall, we identified five major categories of gaps and challenges: (1) Coordination; (2) Training; (3) Infrastructure; (4) Public Awareness; and (5) Research. We developed and prioritized recommendations to address the gaps, estimated the level of resource investment needed, and estimated a timeline for implementation. These prioritized recommendations can be used by the Government of Guinea to plan strategically for future One Health efforts, ideally under the auspices of the national One Health Platform. This work demonstrates an effective methodology for mapping systems and structures for zoonotic diseases, and the benefit of conducting a baseline review of systemic capabilities prior to embarking on capacity building efforts.

This threat assessment addresses the implications of the ongoing Marburg virus disease (MVD) outbreak in
Rwanda for the European Union/European Economic Area (EU/EEA). MVD is a severe ...attribute-to-highlight medbox">disease in humans and,
although uncommon, it has the potential to cause epidemics with significant case fatality. All recorded MVD
outbreaks to date have originated in Africa. MVD is not an airborne disease and is considered not to be
contagious before symptoms appear. Direct contact with the blood and other body fluids of infected people
and animals or indirect contact with contaminated surfaces and materials like clothing, bedding and medical
equipment is required for transmission. The risk of infection is minimised when proper infection prevention and
control precautions are strictly followed. There is no approved treatment or vaccine for MVD; however, several
pharmaceuticals and candidate MVD vaccines are under investigation.
