Contact tracing for COVID-19 is the process of identifying, assessing, and managing people who have been exposed to someone who has been infected with the SARS-CoV-2 virus, while quarantine is the separation of contacts from other people after exposure to a probable or confirmed case of SARS-CoV-2 i...nfection. In the context of growing global population immunity from COVID-19 vaccination and past SARS-CoV-2 infection, WHO recommends that identification, contact, quarantine and follow-up should be prioritized for individuals at high risk who have been in contact with a confirmed or probable case of SARS-CoV-2 infection, rather than targeting all contacts. This updated guidance also introduces shorter recommended quarantine periods, including the ability to further shorten quarantine through the use of testing. National and local health authorities should use risk-based approaches to contact tracing and quarantine that include reviewing and adjusting to their local circumstances and disease epidemiology, population immunity, their health system’s capacities, and risk tolerance.

This module is part of the WHO series The Immunological Basis for Immunization, which was initially developed in 1993 as a set of eight modules, comprising one module on general immunology and seven modules each devoted to one of the vaccines recommended for the Expanded Programme on Immunization, i....e. vaccines against diphtheria, measles, pertussis, polio, tetanus, tuberculosis and yellow fever. Since then, this series has been updated and extended to include other vaccines of international importance. The main purpose of the modules is to provide national immunization managers and vaccination professionals with an overview of the scientific basis of vaccination against a range of important infectious diseases. The modules developed since 1993 continue to be vaccine-specific, reflecting the biological differences in immune responses to the individual pathogens and the differing strategies employed to create the best possible level of protection that can be provided by vaccination. The modules also serve as a record of the immunological basis for the WHO recommendations on vaccine use, published in the WHO vaccine position papers.*

Weekly Epidemiological Record No 9, 2022, 97, 61–80
This position paper supersedes the 2016 publication, “Malaria vaccine: WHO position paper-2016.”1 It includes the updated WHO recommendations on the wider use of the RTS,S/AS01 vaccine for the reduction of malaria morbidity and mortality in ...children living in areas of moderate to high malaria transmission. It also incorporates findings from the evaluation of the WHO-coordinated Malaria Vaccine Implementation Programme (MVIP), recommended by SAGE and MPAG in 2015, and from additional studies since 2015.
This paper does not include findings on vaccine efficacy in infants first vaccinated at 6–12 weeks of age. Because of the lower vaccine efficacy observed in this age category, WHO did not recommend pilot implementation or RTS,S/AS01 vaccine introduction for these young infants. Recommendations2 on the use of RTS,S/AS01 vaccine were discussed by SAGE and MPAG during a joint session in October 2021; evidence presented at the meeting can be accessed at https://terrance.who.int/mediacentre/data/ sage/SAGE_eYB_Oct2021.pdf

9 March 2022, Timely and accurate diagnostic testing for SARS-CoV-2 is an essential part of a comprehensive COVID-19 response strategy. Ag-RDTs can be performed by individuals in which they collect their own specimen, perform a simple rapid test and interpret their test result themselves at a time a...nd place of their choosing, termed COVID-19 self-testing. This interim guidance provides a new recommendation that COVID-19 self-testing, using SARS-CoV-2 Ag-RDTs, should be offered as part of SARS-CoV-2 testing services. It also includes implementation considerations that can guide decisions on whether, and how, to adopt self-testing in different contexts, including the populations being prioritized; the disease prevalence in that population; and the impact on accessibility of testing, health care services and result reporting.

Today, the Commission is proposing to activate the Temporary Protection Directive to offer quick and effective assistance to people fleeing the war in Ukraine. Under this proposal, those fleeing the war will be granted temporary protection in the EU, meaning that they will be given a... residence permit, and they will have access to education and to the labour market.
At the same time, the Commission is also putting forward operational guidelines intended to help Member States' border guards in managing arrivals at the borders with Ukraine efficiently, while maintaining a high level of security. The guidelines also recommend that Member States set up special emergency support lanes to channel humanitarian aid and recall the possibility of granting access to the EU on humanitarian grounds.

TNew data from the World Health Organization reveal that the COVID-19 pandemic has disrupted malaria services, leading to a marked increase in cases and deaths.
According to WHO’s latest World malaria report, there were an estimated 241 million malaria cases and 627 000 malaria deaths worldwide i...n 2020. This represents about 14 million more cases in 2020 compared to 2019, and 69 000 more deaths. Approximately two-thirds of these additional deaths (47 000) were linked to disruptions in the provision of malaria prevention, diagnosis and treatment during the pandemic.
As in past years, the report provides an up-to-date assessment of the burden of malaria at global, regional and country levels. It tracks investments in malaria programmes and research as well as progress across all intervention areas. This latest report draws on data from 87 countries and territories with ongoing malaria transmission.

When situations occur in which unwanted events are rightly or wrongly connected with vaccination, they may erode confidence in vaccines and the authorities delivering them. This document presents the scientific evidence behind WHO’s recommendations on building and restoring confidence in vaccines ...and vaccination, both in ongoing work and during crises. The evidence draws on a vast reserve of laboratory research and fieldwork within psychology and communication. It examines how people make decisions about vaccination; why some people are hesitant about vaccination; and the factors that drive a crisis, covering how building trust, listening to and understanding people, building relations, communicating risk and shaping messages to the audiences may mitigate crises. This document provides a knowledge base for stakeholders who develop communication strategies or facilitate workshops on communication and trust-building activities in relation to vaccines and immunization, such as immunization programme units, ministries of health, public relations and health promotion units, vaccine safety communication trainers and immunization advisory bodies.

As the world population is growing and health care resources are in high demand the pressure on medical services is becoming higher. Developing countries are already at a crisis point in health care provision, and time demands a new approach in structuring medical resources. Primary care is t...he vital pillar for fundamental health care at community level and has been deemed as a cost-effective modality. In the West the primary care physician manages chronic medical conditions in communities and therefore reduces unnecessary hospital admissions. In the West, the primary care system is extremely well organised. Low-income countries must improve teaching, training and funding in primary care. In this article the urgent need for primary care is discussed in developing countries, and ways to minimise costs and improve clinical outcomes at community level.

The meeting addressed the last key area, that is, determining the best method or combination of diagnostic methods for a control programme for S. stercoralis infections in humans.
Dr Montresor’s presentation highlighted that while there is currently no “gold standard” for the... diagnosis of S. stercoralis, there is a felt urgency to optimize diagnostic regimens that are currently available, and in the context of population-based testing (as opposed to individual focused diagnostics in clinical settings).
In other words, the diagnostic test(s) should have good accuracy, but we should remember that in public health we do not aim at individual diagnosis: rather, we need a tool that should help to estimate the prevalence in a population.

This publication presents the Agenda for the Americas on Health, Environment, and Climate Change 2021–2030 (the Agenda). The Agenda is a call to action to the health sector to lead the charge to address environmental determinants of health in the Americas. The Pan American Health Organization (PAH...O) will work with Member States to achieve its goal and objective to ensure healthy lives and promote well-being for all at all ages using a sustainable and equitable approach that places a priority on reducing health inequity. The Agenda has been developed under the umbrella of the WHO Global Strategy on Health, Environment, and Climate Change, and builds upon the commitments set forth in the Sustainable Health Agenda for the Americas 2018–2030 and the PAHO Strategic Plan 2020–2025. The Agenda was developed in consultation with the Technical Advisory Group and through a consensus-driven decision-making process with Member States during the 2019–2020 period. Looking toward the achievement of Sustainable Development Goal 3, the Agenda focuses on: improving the performance of environmental public health programs and institutions; fostering environmentally resilient and sustainable health systems; and promoting environmentally healthy and resilient cities and communities. Its implementation will be context-specific, based on the needs and realities of the countries. It will benefit countries and territories by promoting good governance practices, strengthening the leadership and coordination roles of the health sector, fostering cross-sectoral action, focusing on primary prevention, and enhancing evidence and communication. It will facilitate access to human, technical, and financial resources necessary to address environmental determinants of health and ensure that the Region is fully engaged in global health, environment, and climate change processes and agreements. The objective of the Agenda is to strengthen the capacity of health actors in the health and non-health sectors to address and adapt to environmental determinants of health (EDHs), prioritizing populations living in conditions of vulnerability, in order to meet Outcome 18 of the PAHO Strategic Plan 2020–2025 directly and several other outcomes of the Plan indirectly. To address and adapt to the challenges of EDHs in the Region, an integrated and evidence-informed approach within the health sector and across sectors will be needed, one enabled, and supported by good governance practices, adequate management mechanisms, high-level political will, and adequate human, technical, technological, and financial resources.
