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).

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).

In Control imparts knowledge, provokes reflection and triggers curiosity. The first half of the book provides an overview of the organisations, principles, frameworks and themes that every professional deploying to health emergencies should be aware of. The second half of the book provides practical... advice to help professionals survive and thrive during their mission – from staying healthy, protecting oneself from cyber-attacks and coping with stress to building trust among the host community or dealing with language barriers and the press.
This handbook is free of charge and can be made available in small quantities as long as supply lasts. To order, please send this form to: incontrol-handbook@rki.de

A Situational Assessment and Five-YearAction Plan for the Africa CDC Strengthening Regional Public Health Institutions and Capacity for Surveillance and Response Program
The Strategy to respond to antimalarial drug resistance in Africa is a technical and advocacy document, grounded in the best available evidence to date and aimed at minimizing the threat and impact of antimalarial drug resistance of Plasmodium falciparum parasites in Africa. Its objectives are to: i...) improve the detection of resistance to ensure a timely response; ii) delay the emergence of resistance to artemisinin and artemisinin-based combination therapy (ACT) partner drugs; and iii) limit the selection and spread of resistant parasites where resistance has been confirmed.

This document presents the World Health Organization Operational framework for building climate resilient and low carbon health systems*. ***The framework's goal is to increase the climate resilience of health systems to protect and improve the health of communities in an unstable and changing clima...te, while optimizing the use of resources and implementing strategies to reduce GHG emissions. It aims to contribute to the design of transformative health systems that can provide safe and quality care in a changing climate.
Implementation of the framework's ten components would help health organizations, authorities, and programmes to be better able to anticipate, prevent, prepare for, and manage climate-related health risks and therefore decrease the burden of associated climate-sensitive health outcomes. Implementing low carbon health practices would contribute to climate change mitigation while also improving health outcomes. Achieving these aims is an important contribution to universal health coverage (UHC), global health security, and specific targets within the Sustainable Development Goals (SDGs). The document is a useful resource for decision-makers in health systems, including public health agencies, and other specialized institutions, and for decision-makers in health-determining sectors.

The global tripartite self-assessment survey of country progress in addressing antimicrobial resistance (AMR) is a component of a broader approach for monitoring and evaluation of the global action plan on AMR. This report analyses the results of the second tripartite self-assessment survey. It has ...been developed and run by the three Tripartite organizations (Food and Agriculture Organization of the United Nations (FAO), World Organisation for Animal Health (OIE) and World Health Organization (WHO)) and reflects progress in the human, animal (terrestrial and aquatic), plant, food safety and environmental sectors. 154 countries out of 194 WHO Member States responded to this round of the self-assessment survey – a response rate of 79.4%.

Uganda is Africa's largest refugee-hosting country and ranks fifth globally. Over the decades, Uganda has hosted refugees from nations including South Sudan, the Democratic Republic of Congo, Eritrea, Somalia, Sudan, Burundi, and Rwanda. As of early 2024, it hosts 1 600 000 refugees, primarily in re...fugee settlements in northern and southwestern Uganda, and in Kampala City. Thirteen districts accommodate 94% of these refugees.
The World Health Organization (WHO) and Uganda’s Ministry of Health conducted a joint review mission to provide a comprehensive overview of the health system's response. The aim was to understand service delivery challenges and identify opportunities to further support Uganda in strengthening health system capacity and ensuring continued access to health services for refugees, migrants and host communities.
