Although Shiga toxin-producing Escherichia coli (STEC) have been isolated from a variety of food production animals, they are most commonly associated with ruminants from which we derive meat and milk. Because of the widespread and diverse nature of ruminant-derived food production, coupled with the... near ubiquity of STEC worldwide, there is no single definitive solution for controlling STEC that will work alone or in all situations. Instead, the introduction of multiple interventions applied in sequence, as a “multiple-hurdle scheme” at several points throughout the food chain (including processing, transport and handling) will be most effective.
This report summarizes the review and evaluation of interventions applied for the control of STEC in cattle, raw beef and raw milk and raw milk cheese manufactured from cows’ milk, and also evaluates available evidence for other small ruminants, swine and other animals. The information is presented from primary production, to the end of processing, providing the reader with information on the currently available interventions based on the latest scientific evidence.
This work was undertaken to support the development of guidelines for the control of STEC in beef, raw milk and cheese produced from raw milk by the Codex Committee on Food Hygiene (CCFH).

As the Americas undergo profound demographic change and there are more persons aged 65 years or older than children younger than 5 years, it is crucial to recognize that national immunization programs must be redesigned to ensure comprehensive protection for individuals across the lifespan. By adopt...ing a life course approach (LCA) to immunization, vaccination programs can be tailored to close immunity gaps at different stages of life. The life course approach foresees the establishment of multiple strategies to reduce missed opportunities for vaccination according to age group. This technical document explains the key concepts of the LCA with a focus on immunization by vaccination, as well as the underlying biological mechanisms that require the application different vaccines at different life stages according to changes to the immune system and in the epidemiological situation of a community.

- The goal of diagnostic testing for Ebola and Marburg virus diseases is to identify cases to provide timely and appropriate care and to stop disease transmission.
- All individuals meeting the case definition for Ebola or Marburg virus diseases should be tested.
- The recommended sample type ...for testing for orthoebolaviruses and orthomarburgviruses is whole blood or plasma for living patients, and oral swab for deceased individuals.
- Laboratory confirmation of Orthoebolavirus and Orthomarburgvirus infections and further species identification should be done using nucleic acid amplification testing (NAAT).
- If a suspected case tests negative (living patient) and the blood was drawn less than 72 hours after symptom onset, a second test should be performed with blood drawn more than 72 hours after symptom onset.
- All manipulations in laboratory settings of samples originating from suspected, probable or confirmed cases of Ebola and Marburg virus diseases should be conducted with appropriate biosafety measures according to a risk-based approach.
- Whole or partial genome sequencing can be used to characterize viruses and complement epidemiologic investigations.
- Member States are strongly encouraged to share genetic sequence data (GSD) in publicly accessible databases.
- Member States are required to immediately notify the World Health Organization (WHO) under the International Health Regulations (IHR) 2005 of positive laboratory results.

The role of environmental contamination in transmission of COVID-19 virus is currently not clear. This protocol has been designed to determine (viable) virus presence and persistence on fomites in various locations where a patient infected with COVID-19 is currently receiving care or being isolated,... and to understand how this may relate to COVID-19 transmission events in these settings. It is therefore important that it is done as part of a comprehensive outbreak investigation and that information obtained by environmental studies is combined with the results of epidemiological, laboratory and sequence data from COVID-19 patient investigations.

The Global Burden of Disease (GBD) study, a collaborative endeavour of the World
Health Organization (WHO), the World Bank and the Harvard School of Public Health,
drew the attention of the international health community to the burden of neurological
disorders and many other chronic conditions. T...his study found that the burden of neurological
disorders was seriously underestimated by traditional epidemiological and health
statistical methods that take into account only mortality rates but not disability rates. The
GBD study showed that over the years the global health impact of neurological disorders
had been underestimated.

Indicators for monitoring the 2016 United Nations Political Declaration on Ending AIDS
UNAIDS supports countries to collect information on their national HIV responses through the Global AIDS Monitoring (GAM) framework—an annual collection of 72 indicators on the response to HIV in a country.... These data form part of the data set used to report back to the General Assembly.
Different from the HIV epidemiological estimates that countries produce for data on the state of the epidemic in a country—that is, data for making estimates on the number of people living with HIV, AIDS-related deaths, etc.—GAM collects information on HIV programmes, including the number of people living with HIV who know their HIV status and people on HIV treatment, and on stigma and discrimination. A full list of the indicators is given in the GAM guidelines.

All malaria-endemic countries in the Region of the Americas have taken on the challenge of eliminating malaria and have focused their health programs and strategies on that goal. The risk of emergence of artemisinin resistance in the Americas, the characteristics of P. falciparum parasite, and the e...pidemiological evidence of subnational territories experiencing reintroduction of P. falciparum urge for a call to push for P. falciparum elimination as an intermediate goal of the elimination of all malaria human species. Derived from the elimination of P. falciparum, other important results are expected, such as the empowerment of different actors and entities for the elimination of malaria inspired by the achievements of the elimination of P. falciparum, using early victories as a catalyst. This technical note provides guidance on actions to accelerate P. falciparum elimination in areas close to achieving this goal without compromising unified malaria elimination efforts (P. vivax - P. falciparum), while contributing to the country's ultimate goal of eliminating malaria overall. The acceleration of P. falciparum elimination has several goals: mitigating the risk that resistance to artemisinin and associated drugs will emerge and spread; accelerating the reduction in the total number of malaria cases in areas with a significant proportion of P. falciparum; accelerating malaria elimination (both P. vivax and P. falciparum), considering that P. falciparum is one of the triggers of P. vivax relapses; developing capacities in interventions to accelerate malaria elimination by building on the experience of P. falciparum elimination; and empowering different actors, including high-level authorities, donors, municipalities, and other entities involved in malaria elimination, by inspiring them with the achievements of P. falciparum elimination.

Cardiovascular disease (CVD) is the leading cause of global deaths, with the majority occurring in low- and middle-income countries (LMIC). The primary and secondary prevention of CVD is suboptimal throughout the world, but the evidence-practice gaps are much more pronounced in LMIC. Barriers at the... patient, health-care provider, and health system level prevent the implementation of optimal primary and secondary prevention. Identification of the particular barriers that exist in resource-constrained settings is necessary to inform effective strategies to reduce the identified evidence-practice gaps. Furthermore, targeting modifiable factors that contribute most significantly to the global burden of CVD, including tobacco use, hypertension, and secondary prevention for CVD will lead to the biggest gains in mortality reduction. We review a select number of novel, resource-efficient strategies to reduce premature mortality from CVD, including: (1) effective measures for tobacco control; (2) implementation of simplified screening and management algorithms for those with or at risk of CVD, (3) increasing the availability and affordability of simplified and cost-effective treatment regimens including combination CVD preventive drug therapy, and (4) simplified delivery of health care through task-sharing (non-physician health workers) and optimizing self-management (treatment supporters). Developing and deploying systems of care that address barriers related to the above, will lead to substantial reductions in CVD and related mortality.

WHO, in partnership with the International Society for Prosthetics and Orthotics (ISPO) and the United States Agency for International Development (USAID), has published global standards for prosthetics and orthotics. Its aim is to ensure that prosthetics and orthotics services are people-centred an...d responsive to every individual’s personal and environmental needs. The standards advocate for the integration of prosthetics and orthotics services into health services, under universal health coverage. Implementation of these standards will support countries to fulfil their obligations under the Convention on the Rights of Persons with Disabilities and towards the Sustainable Development Goals, in particular Goal 3: Ensure healthy lives and promote well-being for all at all ages.
The standards provide guidance on the development of national policies, plans and programmes for prosthetics and orthotics services of the highest standard. The standards are divided into two documents: the standards and an implementation manual. Both documents cover four areas of the health system:
policy (governance, financing and information);
products (prostheses and orthoses);
personnel (workforce);
and provision of services.
The Standards have been developed through consultation with experts from around the globe via a steering group, development group and external review group.
