The World Health Organization (WHO) endorses the use of population-based prevalence surveys for estimating the prevalence of trachoma. In general, the prevalence of TF in children aged 1–9 years and the prevalence of TT in adults aged ≥ 15 years are measured at the same time in any district bein...g surveyed. This was the approach of the Global Trachoma Mapping Project, which undertook baseline surveys in > 1500 districts worldwide in order to provide the data required to start interventions where needed.
The survey design recommended by WHO is a two-stage cluster random sample survey, which uses probability proportional to size sampling to select 20–30 villages, and random, systematic or quasi-random sampling to select 25–30 households in each of those villages. In most surveys, everyone aged ≥ 1 year living in selected households is examined.

Many prevention of mother-to-child HIV transmission programmes across Africa initiate HIV-infected (HIV positive) pregnant women on lifelong antiretroviral therapy (ART) on the first day of antenatal care (“same-day” initiation...). However, there are concerns that same-day initiation may limit patient preparation before starting ART and contribute to subsequent non-adherence, disengagement from care and raised viral load. We examined if same-day initiation was associated with viral suppression and engagement in care during pregnancy.
The data suggest that same-day ART initiation during pregnancy is not associated with lower levels of engagement in care or viral suppression through 12 months post-delivery in this setting, providing reassurance to ART programmes implementing Option B+.

In the context of the floods in August 2015 in Myanmar, the Disaster Risk Reduction Working Group (DRR WG) was requested to provide clear recommendations to the DMH (Department of Hydrology and Meteorology)to strengthen preparedness activities, in particular for t...he next Monsoon season. UNDP as the lead of the DRR WG’s Policy Technical Task force carried out a desk review on EW (Early Warning) from all the DRR WG’s members at national and community levels. The document synthesizes the received information related to baseline surveys, lessons learned from the 2015’s floods, studies, project documents and initial recommendations on EW. Those serve as a base to this analysis and its overall recommendations.

This document was prepared in response to a need to review and potentially update the current recommendations for the antibiotic treatment of both inpatient and outpatient management of severe acute malnutrition (SAM). The current recommendations (Table 1) are based on guidelines published in 2013 i...n the WHO Pocketbook for Hospital Care for Children, and the 2013 update on SAM (outpatient management). The global threat of increasing antimicrobial resistance and new data on efficacy and safety profiles requires a re-review of the current evidence to ensure recommendations are the most appropriate. The evidence base for the use of antibiotics in children presenting with uncomplicated SAM has been recently enlarged.

2nd edition. The 2018 Roadmap incorporates an additional critical population: adolescents. Despite making up 1 in 6 of the world’s people, adolescents have been largely overlooked as global momentum to address TB has grown. Spanning the ages of 10–19 years, adolescents are both at risk of TB and... represent an important population for TB control. They often present with infectious TB and frequently have multiple contacts in congregate settings, such as schools and other educational institutions. Nevertheless, few countries capture TB data in suitably age-disaggregated ways to allow full understanding of its impact in this group and even fewer provide the adolescent-friendly services our young people need to access diagnosis and care.

This Community Health Systems (CHS) Catalog country profile is the 2016 update of a landscape
assessment that was originally conducted by the Advancing Partners & Communities (APC) project
in 2014. The CHS Catalog focuses on 25 countries deemed priority by the United States Agency for
Internation...al Development’s (USAID) Office of Population and Reproductive Health, and includes
specific attention to family planning (FP), a core focus of the APC project.
The update comes as many countries are investing in efforts to support the Sustainable Development
Goals and to achieve universal health coverage while modifying policies and strategies to better align
and scale up their community health systems.
The purpose of the CHS Catalog is to provide the most up-to-date information available on community
health systems based on existing policies and related documentation in the 25 countries. Hence, it does
not necessarily capture the realities of policy implementation or service delivery on the ground. APC
has made efforts to standardize the information across country profiles, however, content between
countries may vary due to the availability and quality of the data obtained from policy documents.

Background: Cervical cancer accounts for 23% of cancer incidence and 22% of cancer mortality among women in Burkina Faso. These proportions are more than 2 and 5 times higher than those of developed countries, respectively. Before 2010, cervical cancer prevention (CECAP) services in Burkina Faso wer...e limited to temporary screening campaigns.
Program Description: Between September 2010 and August 2014, program implementers collaborated with the Ministry of Health and professional associations to implement a CECAP program focused on coupling visual inspection with acetic acid (VIA) for screening with same-day cryotherapy treatment for eligible women in 14 facilities. Women with larger lesions or lesions suspect for cancer were referred for loop electrosurgical excision procedure (LEEP). The program trained providers, raised awareness through demand generation activities, and strengthened monitoring capacity.
Methods: Data on program activities, service provision, and programmatic lessons were analyzed. Three data collection tools, an individual client form, a client registry, and a monthly summary sheet, were used to track 3 key CECAP service indicators: number of women screened using VIA, proportion of women who screened VIA positive, and proportion of women screening VIA positive who received same-day cryotherapy.
Results: Over 4 years, the program screened 13,999 women for cervical cancer using VIA; 8.9% screened positive; and 65.9% received cryotherapy in a single visit. The proportion receiving cryotherapy on the same day started at a high of 82% to 93% when services were provided free of charge, but dropped to 51% when a user fee of $10 was applied to cover the cost of supplies. After reducing the fee to $4 in November 2012, the proportion increased again to 78%. Implementation challenges included difficulties tracking referred patients, stock-outs of key supplies, difficulties with machine maintenance, and prohibitive user fees. Providers were trained to independently monitor services, identify gaps, and take corrective actions.
Conclusions: Following dissemination of the results that demonstrated the acceptability and feasibility of the CECAP program, the Burkina Faso Ministry of Health included CECAP services in its minimum service delivery package in 2016. Essential components for such programs include provider training on VIA, cryotherapy, and LEEP; provider and patient demand generation; local equipment maintenance; consistent supply stocks; referral system for LEEP; non-prohibitive fees; and a monitoring data collection system.

3rd edition. In 2001, Uganda adapted the Integrated Disease Surveillance and Response (IDSR) developed by World Health Organization (WHO) for member states in African region. The Ministry of Health has been implementing the IDSR strategy since then with success across the country. This strategy prov...ides the opportunity for rational use of resources and maximises investments in health surveillance systems. The 3rd edition IDSR guidelines incorporates lessons learnt from previous
epidemics, new frameworks like the Global Health Security Agenda (GHSA), One Health, Disaster Risk Management (DRM), the WHO regional strategy for health security and emergencies, and the rising non-communicable diseases, and aims to strengthen implementation of IHR (2005) core surveillance and response capacities. These guidelines have been adapted to reflect national priorities, policies and public health structures; and shall be used in conjunction with other similar
guidelines/strategies or initiatives.
Overall, the 3rd edition technical guidelines will incorporate the following:
• Strengthening Indicator Based Surveillance
• Strengthening Event Based Surveillance
• Improving community-based disease surveillance
• Improving Cross Border Surveillance and response
• Scaling up e-IDSR implementation
• Improving reporting and information sharing platforms
• Improved data sharing across sectors
• Tailoring IDSR to Emergency or Disaster contexts
The 3rd edition guidelines are intended for use as:
• A general reference for surveillance activities across all levels
• A set of definitions for thresholds that trigger some action for response
• A stand-alone reference for level-specific guidelines on surveillance and response
• A resource for developing training, supervision and evaluation of surveillance activities
• A guide for improving early detection and preparedness for outbreak response.

Each humanitarian setting provides distinct opportunities and challenges for actors to coordinate and collaborate at strategic and operational levels. The Health and Protection Joint Operational Framework has been developed to ensure that the health and protection response during humanitarian emerge...ncies can adapt to each environment and is adequately coordinated to ensure high-quality services to meet the needs of affected individuals and at-risk groups based on their situation or vulnerabilities.
The Health and Protection JOF was conceived in 2019 as a collaboration between the Global Health Cluster (GHC), the Global Protection Cluster (GPC) and its Areas of Responsibility (AoRs), the Inter-Agency Standing Committee Reference Group on Mental Health and Psychosocial Support in Emergency Settings (IASC MHPSS RG), and the Inter-Agency Working Group for Reproductive Health in Crisis (IAWG), in addition to key technical experts.
A Steering Group (SG) comprised of representatives from each of these entities guided the framework through a joint global analysis of good practices, gaps, and barriers to integrated and inter-sectoral response coordination. This included a mixed methods review of policy and practice, a survey of humanitarian experts, multiple case studies, structured stakeholder interviews, and field visits. This exercise produced a zero-draft which was then reviewed by field practitioners in three operational contexts to clarify and fully coordinate its operationally focused lens. Finally, the JOF was reviewed by the SG including via a series of consultations in early 2023 to consolidate the current framework.

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.

Cystic fibrosis (CF) was earlier thought to be a disease prevalent in the West among Caucasians. However, quite a number of recent studies have uncovered CF cases outside of this region, and reported hundreds of unique and novel variant forms of CFTR. Here, we discuss the evidence of CF in parts of... the world earlier considered to be rare; Africa, and Asia. This review also highlighted the CFTR mutation variations and new mutations discovered in these regions. This discovery implies that the CF data from these regions were earlier underestimated. The inadequate awareness of the disease in these regions might have contributed towards the poor diagnostic facilities, under-diagnosis or/and under-reporting, and the lack of CF associated health policies. Overall, these regions have a high rate of infant, childhood and early adulthood mortality due to CF. Therefore, there is a need for a thorough investigation of CF prevalence and to identify unique and novel variant mutations within these regions in order to formulate intervention plans, create awareness, develop mutation specific screening kits and therapies to keep CF mortality at bay.

Reporting period: January 2014 – December 2014
The human immunodeficiency virus (HIV) epidemic in Myanmar is concentrated among men who have sex with men (MSM), people who inject drugs (PWID) and female sex workers (FSW). HIV prevalence in the adult population aged 15 years and older was esti...mated at 0.54% in 2014. But data from HIV Sentinel Sero-Surveillance (HSS) indicates higher prevalence in 2014 among key populations: FSW 6.3%, MSM 6.6% and PWID 23.1%. Compared to 2012 data, the prevalence has declined from 7.1% in FSW and 8.9% in MSM, but has increased from 18% in PWID.
Epidemiological modelling suggests that in 2014 there were around 212,000 people living with HIV (PLHIV) in Myanmar, 34% of whom were females. Nearly 11,000 people died of HIV-related illnesses, compared to approximately 15,000 in 2011. An estimated 9,000 new infections occurred in 2014.

Excessive consumption of salt (more than 5 g per day) raises blood pressure, a major risk factor for cardiovascular diseases such as heart disease and stroke, and is the leading cause of death in the WHO European Region. Many countries in the Region have initiated national salt reduction strategies,... including public awareness campaigns, reformulation, and front-of-pack nutrition labelling. However, despite ongoing efforts, surveillance data indicate that salt intake still far exceeds the limits recommended by WHO to protect health.

Since the release of the first volume in May 2020, the COVID-19 pandemic has continued to rage around the world. By mid-March, 2021, countries around the globe had reported over 123 million cases—a nearly five-fold increase since this report’s previous volume—and over 2.7 million deaths attrib...uted to the disease. And while new case loads are currently on the rise again, the global health community has already administered almost 400 million doses of vaccines, at last offering some signs of hope and progress.
Economic impacts threaten to undo decades of recent progress in poverty reduction, child nutrition and gender equality, and exacerbate efforts to support refugees, migrants, and other vulnerable communities. National and local governments—together with international and private-sector partners—must deploy vaccines as efficiently, safely and equitably as possible while still monitoring for new outbreaks and continuing policies to protect those who do not yet have immunity.
More than ever, the world needs reliable and trustworthy data and statistics to inform these important decisions. The United Nations and all member organizations of the Committee for the Coordination of Statistical Activities (CCSA) collect and make available a wealth of information for assessing the multifaceted impacts of the pandemic. This report updates some of the global and regional trends presented in Volume I and offers a snapshot of how COVID-19 continues to affect the world today across multiple domains.

Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha...ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.

Climate change is increasing risks to human health and to the health systems that seek to protect the safety and well-being of populations. Health authorities require information about current associatio...ns between health outcomes and weather or climate, vulnerable populations, projections of future risks and adaptation opportunities in order to reduce exposures, empower individuals to take needed protective actions and build climate-resilient health systems. An increasing number of health authorities from local to national levels seek this information by conducting climate change and health vulnerability and adaptation assessments. While assessments can provide valuable information to plan for climate change impacts, the results of many studies are not helping to build the global evidence-base of knowledge in this area. They are also often not integrated into adaptation decision making, sometimes because the health sector is not involved in climate change policy making processes at the national level. Significant barriers related to data accessibility, a limited number of climate and health models, uncertainty in climate projections, and a lack of funding and expertise, particularly in developing countries, challenge health authority efforts to conduct rigorous assessments and apply the findings. This paper examines the evolution of climate change and health vulnerability and adaptation assessments, including guidance developed for such projects, the number of assessments that have been conducted globally and implementation of the findings to support health adaptation action. Greater capacity building that facilitates assessments from local to national scales will support collaborative efforts to protect health from current climate hazards and future climate change. Health sector officials will benefit from additional resources and partnership opportunities to ensure that evidence about climate change impacts on health is effectively translated into needed actions to build health resilience.
