This report on progress achieved in the WHO European Region and Member States in implementing the European food and nutrition action plan 2015–2020 presents selected epidemiological data on the nutritional status of populations throughout the Region and on implementation of policies recommended in... regional and global frameworks to promote healthy nutrition and prevent obesity. The data contained in the report are derived from the responses of Member States to the WHO Global nutrition policy review questionnaire.

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).

An estimated 1.3 billion people globally experience significant disability. This figure has grown over the last decade and will continue to rise due to demographic and epidemiological changes. In 2022, the World Health Organization launched the Global report on health equity for persons with disabil...ities. This report demonstrated that many persons with disabilities are still being left behind. Experiencing persistent health inequities, persons with disabilities die earlier, they have poorer health and functioning, and they are more affected by health emergencies than the general population. These differences are largely associated with unjust factors both inside and beyond the health sector and are avoidable. The Global Report called upon Member States to take actions to make health sector more inclusive for persons with disabilities through the primary health care approach. This will be essential for countries to make health coverage truly universal and to progress towards other health-related targets in the sustainable development goals.

Interim Guidance October 2022. This addendum addresses some of the methodological aspects of VE evaluations that have been learned during the past year, as well as those that have become relevant in the current epidemiological setting of the COVID-19 pandemic. For some of the COVID-19 vaccine method...ology issues there are still insufficient data to make a recommendation, in which case different options for approaching VE evaluations are presented.

This project aimed to reduce the risk of vector-borne infection with Chagas disease by
controlling triatomine bugs, the vectors transmitting the parasite of Chagas disease, and
establishing an epidemiological surveillance system with community participation.
This protocol establishes the principles and definitions of a surveillance system devised by the WHO Health in Prisons Programme (HIPP) to monitor the evolution of COVID-19-related epidemiological data in prisons and other places of detention and to report the main measures adopted to prevent,... control and manage the spread of the disease.

Heart failure is an important global health problem, and the associated public health and economic effect is increasing across all societies and geographies.
Epidemiological studies have estimated that there are more than 25 million patients with heart failure globally, and population-based studie...s from North America and Europe have estimated that 1–2% of people are living with heart failure. Factors such as ageing and expanding populations have contributed to increasing hospital admissions for heart failure.

Onchocerciasis used to be an important public health problem in Africa, with over 37 million people infected and millions suffering from debilitating skin disease, terrible itching, impaired vision and
blindness. But the epidemiological situation has improved dramatically over the last two decades.... Community directed treatment with ivermectin has effectively brought the disease under control in most endemic areas where onchocerciasis is no longer a public health risk.

Rwanda’s fourth health sector strategic plan (HSSP4) is meant to provide the health sector with a Strategic Plan that will highlight its commitments and priorities for the coming 6 years. It will be fully integrated in the overall economic development plan of the Government. HSSP4 will fulfill the... country’s commitment expressed in the national constitution, National Strategy for Transformation (NST) and the aspirations of the Health Sector Policy 2015. The strategies herein adhere to the Universal Health Coverage (UHC) principles towards realisation of the Sustainable Development Goals (SDGs). HSSP4 therefore lays a foundation for Vision 2050 (“The Rwanda We Want”), which will transform Rwanda into a high-income country by 2050. HSSP4 anticipates the epidemiological transition of the country, the increase in population and life expectancy and the expected increase of the health needs of the elderly, notably in Non Communicable Diseases (NCDs). HSSP4 also anticipates a decrease in external financial inflows, hence it is imperative to build secure / resilient health systems.

Chagas disease caused by Trypanosoma cruzi is a public health issue in Latin America. This highly diverse parasite is divided into at least seven discrete typing units (DTUs) TcI-TcVI and Tcbat. Some DTUs have been associated with geographical distribution in epidemiological scenarios and clinical m...anifestations, but these aspects remain poorly understood. Many studies have focused on studying the parasite and its vectors/hosts, using a wide variety of genetic markers and methods. Here, we performed a systematic review of the literature for the last 20 years to present an update of DTUs distribution in the Americas, collecting ecoepidemiological information. We found that the DTUs are widespread across the continent and that there is a whole gamma of genetic markers used for the identification and genotyping of the parasite. The data obtained in this descriptor could improve the molecular epidemiology studies of Chagas disease in endemic regions.

Recency assays use one or more biomarkers to identify whether HIV infection in a person is recent (usually within a year or less) or longstanding. Recency assays have been used to estimate incidence in representative cross-sectional surveys and in epidemiological studies to better understand the pat...terns and distributions of new and longstanding HIV infections.
This technical guidance outlines best practices regarding the appropriate use of HIV recency assays for surveillance purposes and updates 2011 technical guidance from the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) on the use of HIV recency assays.

I examine the effectiveness of donors in targeting the highest burden of malaria in the Democratic Republic of Congo when health information structure is fragmented. I exploit local variations in the burden of malaria induced by mining activities as well as financial and epidemiological data from he...alth facilities to estimate how local aid is matching local health needs. Using a regression discontinuity design, I find significant but quantitatively small variations in aid to health facilities located within mining areas. Comparing local aid with the additional cost of treatment and prevention associated with the increased risk of malaria transmission, I find suggestive evidence that local populations with the highest burden of the disease receive a proportionately lower share of aid compared to neighbouring areas with reduced exposure to malaria infection. The evidence of disparities in the allocation of aid for malaria supports the view that donors may have inaccurate information about local population needs.
