Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

Guidance has been updated on a number of chemicals: asbestos, bentazone, chromium, iodine, manganese, microcystins, nickel, silver, tetrachloroethene and trichloroethene. Guidance has also been added for chemicals not previously assessed in the Guidelines: anatoxin-a and analogues, cylindrospermopsi...ns and saxitoxins. The new guidance on organotins has replaced the prior guidance focused on dialkyltins. With these updates, the guideline values for tetrachloroethene and trichloroethene have been revised while new guideline values for cylindrospermopsins, manganese, microcystins, and saxitoxins have been established .
Updated information on cyanobacteria has been included, introducing an alert level framework for early-warning and to guide short-term management responses. Guidance has also been updated in the sections on adequacy of water supply, climate change, emergencies, food production and processing, and radiological aspects, particularly on managing radionuclides when exceeding WHO screening values and guidance levels.

Updated 2022. This guide addresses the care pathway from presentation of the patient to a health facility to patient discharge. It considers different levels of disease severity, from asymptomatic individuals to critically ill patients. Accounting for variations in the benefits and harms of chest im...aging in different situations, remarks are provided to describe the circumstances under which each recommendation would benefit patients. The guide also includes implementation considerations for different settings, provides suggestions for impact monitoring and evaluation and identifies knowledge gaps meriting further research.

Die WHO hat mit Hilfe der Delphi-Methode eine klinische Falldefinition für das Post-COVID-19-Syndrom entwickelt, die 12 Domänen umfasst und in allen Bereichen verwendet werden kann. Diese erste Version wurde von Patienten, Forschern und anderen Personen aus allen WHO-Regionen entwickelt, wobei dav...on ausgegangen wird, dass sich die Definition ändern kann, wenn sich neue Erkenntnisse ergeben und sich unser Verständnis der Folgen von COVID-19 weiterentwickelt.
Die Post-COVID-19-Erkrankung tritt bei Personen mit einer wahrscheinlichen oder bestätigten SARS-CoV-2-Infektion in der Anamnese auf, in der Regel drei Monate nach dem Auftreten von COVID-19 mit Symptomen, die mindestens zwei Monate anhalten und nicht durch eine andere Diagnose erklärt werden können. Zu den häufigen Symptomen gehören Müdigkeit, Kurzatmigkeit, kognitive Störungen, aber auch andere Symptome, die sich im Allgemeinen auf das tägliche Leben auswirken. Die Symptome können nach der anfänglichen Genesung von einer akuten COVID-19-Episode neu auftreten oder nach der ersten Erkrankung fortbestehen. Die Symptome können auch schwanken oder im Laufe der Zeit wieder auftreten.

Eight years after Super Typhoon Haiyan, the most destructive storm to ever hit the Philippines, Super Typhoon Rai brought similar torrential rains, violent winds, mudslides, floods and storm surges to central parts of the Philippines, leaving a wide path of destruction and debris in its wake. While ...not as powerful as Haiyan in terms of wind strength, evidence shows that Rai damaged houses, infrastructure and livelihoods on a comparable scale or in even greater numbers. Most striking, Rai damaged 1.57 million homes, 500,000 more than Haiyan, across 11 of the Philippines 17 regions, with around 180,000-200,000 people still displaced – either still in evacuation centers or staying with friends, family or other temporary housing.

The COVID-19 pandemic has led to large increases in healthcare waste, straining under resourced healthcare facilities and exacerbating environmental impacts from solid waste. This report quantifies the additional COVID-19 healthcare waste generated, describes current healthcare waste management syst...ems and their deficiencies, and summarizes emerging best practices and solutions to reduce the impact of waste on human and environmental health. The recommendations included in the report build on actions in the WHO manifesto for a healthy recovery from COVID-19: prescriptions and actionables for a healthy and green recovery. They target the global, national and facility levels to promote a “win–win” scenario for COVID-19 PPE use, testing and vaccinations that are safe and support environmental sustainability.

his guidance provides interim guidance for the integration of SARS-CoV-2 and influenza virologic and genomic surveillance, from sentinel site case enrolment and sampling to the eventual sharing of the virus sequence data, a process known as end-to-end surveillance. This guidance builds on experience...s and lessons learned as countries adapted their influenza surveillance systems in the context of the COVID-19 pandemic and reviews new evidence to provide guidance on end-to-end surveillance. The guidance includes new algorithms and strategies to adapt sentinel systems to make them resilient and agile for addressing global and national surveillance needs for influenza and COVID-19.covid-

Almost eight years of active fighting have had profound consequences on the lives of millions of people in the conflict-affected Donetska and Luhanska oblasts of eastern Ukraine. An estimated 2.9 million people are projected to need humanitarian assistance in 2022, with some 55 per cent living in th...e non-Government controlled area (NGCA).1 1 According to the national Ukrainian legislation, such areas have been defined as the temporarily occupied territories of Donetska and Luhanska oblasts.

Key Findings: Exposure to vaccination information from faith leaders and health facilities was associated with increased likelihood of vaccination uptake. The significant association between exposure to a... greater number of immunization information sources and increased likelihood of vaccination uptake reinforces the need for multiple sources to provide consistent and accurate immunization information to facilitate positive vaccination behavior.
Key Implications: Social and behavior change communication interventions may optimize the promotion of immunization services through multiple information sources such as health facilities and community-based assets including faith leaders and lay community health workers. Religion and faith play an important role in how people understand health and make health decisions. In Sierra Leone and other similar settings, interventions to improve uptake of immunization services may be enhanced by proactively engaging faith leaders.

Cascading risks from rising prices and supply disruptions, April 2022.
Global resource markets are still reeling from the impacts of Russia’s invasion of Ukraine; the two countries are major suppliers of energy, food and fertilizers. Supply disruption and the sudden imposition, in response to the... crisis, of unprecedented economic sanctions, trade restrictions and policy interventions have caused prices of commodities to skyrocket.
Before the conflict, demand for global resources already exceeded supply and drove up prices as economies rebounded after the COVID-19 pandemic. This gave rise to a global cost-of-living crisis, characterized by increasing levels of energy and food poverty. This situation is likely to become much worse as a consequence of the war in Ukraine, and poses a threat to human security, particularly among low-income and vulnerable populations.
