This paper introduces a new dataset of official financing—including foreign aid and other forms of concessional and non-concessional state financing—from China to 138 countries between 2000 and 2014. We use these data to investigate whether and to what extent Chinese aid affects economic growth ...in recipient countries. To account for the endogeneity of aid, we employ an instrumental-variables strategy that relies on exogenous variation in the supply of Chinese aid over time resulting from changes in Chinese steel production. Variation across recipient countries results from a country’s probability of receiving aid. Controlling for year- and recipient-fixed effects that capture the levels of these variables, their interaction provides a powerful and excludable instrument. Our results show that Chinese official development assistance (ODA) boosts economic growth in recipient countries. For the average recipient country, we estimate that one additional Chinese ODA project produces a 0.7 percentage point increase in economic growth two years after the project is committed. We also benchmark the effectiveness of Chinese aid vis-á-vis the World Bank, the United States, and all members of the OECD’s Development Assistance Committee (DAC).

Donor financing to low- and middle-income countries for reproductive, maternal, newborn, and child health increased substantially from 2008 to 2013. However, increased spending by donors might not improve outcomes, if funds are delivered in ways that undermine countries’ public financial managemen...t systems and incur high transaction costs for project implementation

Internationally, there is a growing concern over antimicro-bial resistance (AMR) which is currently estimated to ac-count for more than 700,000 deaths per year worldwide. If no appropriate measures are taken to halt its pro-gress, AMR will cost approximately 10 million lives andabout US$100 trillion... per year by 2050. In contrast tosome other health issues, AMR is a problem that con-cerns every country irrespective of its level of incomeand development as resistant pathogens do not respect borders.Despite the threat presented by AMR, the 2014 WorldHealth Organization (WHO) and the recent O’Neill re-port describe significant gaps in surveillance, standardmethodologies and data sharing. The 2014 WHOreport identified Africa and South East Asia as the regions without established AMR surveillance systems.

Taenia saginata is a zoonotic tapeworm that is of economic importance in countries where cattle are kept. The parasite is transmitted from human tapeworm carriers (taeniosis) to bovines (cysticercosis) by excretion of eggs or proglottids containing eggs into the environment via the stool. Bovines ca...n then ingest the eggs through contaminated feed or water. After ingestion, the eggs hatch and release oncospheres in the small intestines, where the oncospheres penetrate the intestinal wall to reach the blood circulation. This distributes them throughout the body, but primarily to muscle tissue, where they develop into cysticerci. For humans to become infected with T. saginata, raw or undercooked bovine meat or offal containing infective cysts must be consumed. Bovine cysticercosis has been associated with various environmental factors related to water sources, such as animals having access to surface water, flooding of pastures and proximity to wastewater sources.

Since 1996, trachoma has been targeted for elimination as a public health problem worldwide. The active trachoma criterion for national elimination as a public health problem is a TF1–9 < 5%, sustained for at least two years in the absence of antibiotic mass drug administration (MDA), in each form...erly endemic EU. Using A, F and E, health ministries and their partners have made considerable progress towards achieving this criterion in formerly endemic EUs worldwide. In 2002, an estimated 1517 million people lived in EUs in which EU-wide implementation of the A, F and E components of SAFE were thought to be needed for the purposes of global elimination of trachoma as a public health problem; by June 2021, that number had fallen to 136.2 million, a 91% reduction. Approximately 85% of the 136.2 million people living in EUs needing A, F and E in June 2021 were in WHO’s African Region.

The chapter Dementia in Latin America and the Caribbean: Prevalence, Incidence, Impact, and Trends over Time, is part of the publication series titled “Decade of Healthy Aging: situation and challenges”. This document aims to provide an outline of the current situation in Latin America and the C...aribbean in respect of the prevalence and incidence of dementia and its impact on the health status of older people. As dementia is a significant global health problem which also has social and economic impacts this document highlights the importance of monitoring dementia in the region. The document evidences that dementia is one of the main contributors to dependence and disability in older people in Latin America and the Caribbean and, although its prevalence and incidence increase exponentially with age, it is not part of normal aging. Alzheimer’s disease is the most common dementia, and there is no cure for this condition, but with timely diagnosis is possible to ameliorate symptoms. It is important to assess what are the needs of people leaving with dementia and their families and to integrate dementia risk reduction strategies in pre-existing strategies for other non-communicable diseases. As shown in the report, despite the huge burden dementia is still underdiagnosed, and it is fundamental to better monitor its prevalence, incidence and the different societal impact that dementia can have. For that, it is crucial to promote the use of harmonized methodologies to address this information in a broader number of studies and countries in the region. This can contribute to the generation of direct actions to decrease dementia risk and lead to healthier lives for people with dementia and their families.

Diarrhea is one of the world’s leading causes of child illness and death, and rotavirus is the most common cause of severe diarrhea. Yet it can be prevented and treated. There is a vaccine. And while hundreds of thousands of children in India will gain access to rotavirus vaccines -part of a natio...nal introduction marking Asia’s largest so far -millions of children globally still lack access. This new report from the Rota Council summarizes the latest evidence on rotavirus disease and vaccines and identifies 21 recommendations for stakeholders to scale up coverage and prevent hundreds of thousands of child deaths annually.

Mass population movements have accounted for the emergence of Chagas disease (CD) outside endemic regions,
including the European Union/European Economic Area (EU/EEA). The parasite responsible for causing CD,
Trypanosoma cruzi (T. cruzi), can be transmitted through substances of human origin (SoH...O), such as blood
transfusions and organ transplantations [1], posing a risk to the recipients. This, together with congenital
transmission, is of increasing concern in non-endemic countries

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.

Interim guidance, 6 October 2021
Direct detection of SARS-CoV-2 viral proteins (antigens) in nasal swabs and other respiratory secretions using lateral flow immunoassays (also known as rapid diagnostic tests, RDTs) offers a faster and less expensive method to test for SARS-CoV-2 than the reference ...method, nucleic acid amplification tests (NAATs). This interim guidance offers recommendations on the priority uses of antigen-detecting rapid diagnostic tests (Ag-RDTs) in specific populations and settings, including (i) for primary case detection in symptomatic individuals suspected to be infected and asymptomatic individuals at high risk of COVID-19, (ii) for contact tracing, (iii) during outbreak investigations and (iv) to monitor trends of disease incidence in communities. Ag-RDTs meeting minimum performance requirements can be used outside of clinical and laboratory settings, including in communities, by trained operators in accordance with instructions. The guidance additionally provides recommendations on implementation, product selection and storage.
