Background
Noncommunicable diseases are major contributors to morbidity and mortality worldwide. Modifying the risk factors for these conditions, such as physical inactivity, is thus essential. Addressing the context or circumstances in which physical activity occurs may promote physical activity a...t a population level. We assessed the effects of infrastructure, policy or regulatory interventions for increasing physical activity.
Methods
We searched PubMed, Embase and clinicaltrials.gov to identify randomised controlled trials (RCTs), controlled before-after (CBAs) studies, and interrupted time series (ITS) studies assessing population-level infrastructure or policy and regulatory interventions to increase physical activity. We were interested in the effects of these interventions on physical activity, body weight and related measures, blood pressure, and CVD and type 2 diabetes morbidity and mortality, and on other secondary outcomes. Screening and data extraction was done in duplicate, with risk of bias was using an adapted Cochrane risk of bias tool. Due to high levels of heterogeneity, we synthesised the evidence based on effect direction.
Results
We included 33 studies, mostly conducted in high-income countries. Of these, 13 assessed infrastructure changes to green or other spaces to promote physical activity and 18 infrastructure changes to promote active transport. The effects of identified interventions on physical activity, body weight and blood pressure varied across studies (very low certainty evidence); thus, we remain very uncertain about the effects of these interventions. Two studies assessed the effects of policy and regulatory interventions; one provided free access to physical activity facilities and showed that it may have beneficial effects on physical activity (low certainty evidence). The other provided free bus travel for youth, with intervention effects varying across studies (very low certainty evidence).
Conclusions
Evidence from 33 studies assessing infrastructure, policy and regulatory interventions for increasing physical activity showed varying results. The certainty of the evidence was mostly very low, due to study designs included and inconsistent findings between studies. Despite this drawback, the evidence indicates that providing access to physical activity facilities may be beneficial; however this finding is based on only one study. Implementation of these interventions requires full consideration of contextual factors, especially in low resource settings.

Evidence-based psychological interventions are an important part of health, social, protection and education services and can help increase access to effective mental health treatments and progression towards universal health coverage.
This manual provides managers and others responsible for plan...ning and delivering services with practical guidance on how to implement manualized psychological interventions for adults, adolescents and children. It covers the five key implementation steps: make an implementation plan; adapt for context; prepare the workforce; identify, assess and support potential beneficiaries; and monitor and evaluate the service.

A Global Inventory of Alternative Medical Waste Treatment Technologies
Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a...nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.

Vol. 2: Clinicians' Guide
Clinicians’ Guide is designed to assist busy medical practitioners in the field with patient management by providing current, essential, practical guidance and background, packaged into a single resource
This handbook was designed primarily as a tool for district clinical specialist teams (DCSTs), and for the provincial specialists who will guide and support their work. This handbook will also be useful to managers of health facilities, heads of clinical units and nurses, doctors and allied health w...orkers at the coalface of clinical care. This handbook will be of interest to district managers and other members of the district management team who are dedicated to developing the capacity of the district health system to respond
effectively to the health needs of the population they serve. It will help them understand the role of the DCSTs and the type of
activities they need to engage in to improve the quality of care

In contrast to bilateral aid, aid disbursed from
multilateral institutions increased significantly at the onset
of the COVID-19 pandemic. Yet, at a time when a coherent
and effective multilateral response is needed most, the
COVID-19 pandemic revealed a shifting landscape of donor
agencies that... struggle with basic functions, such as crossnational coordination. While multilaterals are uniquely
positioned to transcend national priorities and respond
to pandemics, functionally we find official development
assistance (ODA) from these entities may increasingly
mimic the attributes of bilateral aid. We explore three
important, but not comprehensive, attributes of aid leading
up to and during the COVID-19 pandemic: (1) earmarking,
(2) donor concentration and (3) aid modality.

Cholera epidemics continue to be a major public health problem in many countries around the
world. When epidemics strike, they can spread rapidly. The disease can also evolve quickly;
patients with severe disease can die of dehydration hours after showing the first symptoms of
cholera.
For COVID-19, as for many infectious diseases, the true level of transmission is frequently underestimated because a substantial proportion of people with the infection are undetected either because they are asymptomatic or have only mild symptoms and thus typically fail to present at healthcare fac...ilities. There may also be neglected or under-served segments of the population who are less likely to access healthcare or testing. Under-detection of cases may be exacerbated during an epidemic, when testing capacity may be limited and restricted to people with severe cases and priority risk groups (such as frontline healthcare workers, elderly people and people with comorbidities). Cases may also be misdiagnosed and attributed to other diseases with similar clinical presentation, such as influenza.
Differences in mortality between groups of people and countries are important proxy indicators of relative risk of death that guide policy decisions regarding scarce medical resource allocation during the ongoing COVID-19 pandemic. This document is intended to help countries estimate CFR and, if possible, IFR, as appropriately and accurately as possible, while accounting for possible biases in their estimation

It is intended for clinicians who are working in intensive care units (ICUs) in low and middle-income countries and managing adult and pediatric patients with severe forms of acute respiratory infection (SARI), including severe pneumonia, acute respiratory distress syndrome (ARDS), sepsis and septic... shock. It is a hands-on practical guide to be used by health care professionals involved in clinical care management during outbreaks of influenza virus (seasonal) human infection due avian influenza virus (H5N1, H7N9), MERS-CoV, COVID-19 or other emerging respiratory viral epidemics.
