We combine data on Chinese development projects with data from Demographic and Health Surveys to study the impact of Chinese aid on household welfare in sub-Saharan Africa. We use a novel methodology to te
...
st the effect of Chinese aid on three important development outcomes: education, health, and nutrition. For each outcome, we use difference-in-difference estimations to compare household areas near Chinese project sites to control areas located farther away, before and after receiving Chinese aid. This empirical strategy rules out many confounding factors that can bias measuring the impact of Chinese aid on our outcome variables. First, we find that Chinese projects significantly improve education and child mortality in treatment areas, but do not significantly affect nutrition. Second, social sector projects have a larger effect on outcomes than economic projects. Third, we do not find significant effects for projects that ended more than five years before the post-treatment survey wave. Our results are robust to a host of robustness checks.

Objective: To identify gaps in national stroke guidelines that could be bridged to enhance the quality of stroke care services in low- and
middle-income countries.
Methods: We systematically searched medical databases
...
and websites of medical societies and contacted international organizations.
Country-specific guidelines on care and control of stroke in any language published from 2010 to 2020 were eligible for inclusion. We reviewed
each included guideline for coverage of four key components of stroke services (surveillance, prevention, acute care and rehabilitation).
We also assessed compliance with the eight Institute of Medicine standards for clinical practice guidelines, the ease of implementation of
guidelines and plans for dissemination to target audiences.
Findings: We reviewed 108 eligible guidelines from 47 countries, including four low-income, 24 middle-income and 19 high-income countries.
Globally, fewer of the guidelines covered primary stroke prevention compared with other components of care, with none recommending
surveillance. Guidelines on stroke in low- and middle-income countries fell short of the required standards for guideline development;
breadth of target audience; coverage of the four components of stroke services; and adaptation to socioeconomic context. Fewer low- and
middle-income country guidelines demonstrated transparency than those from high-income countries. Less than a quarter of guidelines
encompassed detailed implementation plans and socioeconomic considerations.
Conclusion: Guidelines on stroke in low- and middle-income countries need to be developed in conjunction with a wider category of
health-care providers and stakeholders, with a full spectrum of translatable, context-appropriate interventions.

ement considerations for COVID-19 self-testing. The Africa CDC recommends the use of rapid antigen self-testing within two key scenarios. The first includes testing for case identification within scenarios with a high risk of infection, including symptomatic cases and contacts of a confirmed case. The second scenario involves general screening within scenarios of low or unknown risk exposure allowing for self-care such as before gatherings with at-risk individuals and prior to participation in events involving members of different households. Within these scenarios, a positive test result indicates likelihood of current infection, while a negative test result indicates a lower risk of active infection, though it does not rule out infection altogether. All positive cases should be managed following the national COVID-19 management protocol of Member States.ssur

These questions can only be answered in post-introduction vaccine effectiveness studies.This guidance document outlines an approach to leverage existing surveillance systems for Severe Acute Respirato

ry Infection (SARI) to estimate COVID-19 vaccine effectiveness (VE) in preventing SARI associated with laboratory-confirmed SARS-CoV-2 using existing SARI surveillance systems. The approach uses the test-negative design to evaluate VE; cases are SARI patients who tested positive for SARS-CoV-2, and controls are SARI patients who tested negative for SARS-CoV-2.

INTRODUCTION: Health service use among the public can decline during outbreaks and had been predicted among low and middle-income countries during the COVID-19 pandemic. In March 2020, the governmen
...
t of the Democratic Republic of the Congo (DRC) started implementing public health measures across Kinshasa, including strict lock-down measures in the Gombe health zone.
METHODS: Using monthly time series data from the DRC Health Management Information System (January 2018 to December 2020) and interrupted time series with mixed effects segmented Poisson regression models, we evaluated the impact of the pandemic on the use of essential health services (outpatient visits, maternal health, vaccinations, visits for common infectious diseases and non-communicable diseases) during the first wave of the pandemic in Kinshasa. Analyses were stratified by age, sex, health facility and lockdown policy (i.e, Gombe vs other health zones).
RESULTS: Health service use dropped rapidly following the start of the pandemic and ranged from 16% for visits for hypertension to 39% for visits for diabetes. However, reductions were highly concentrated in Gombe (81% decline in outpatient visits) relative to other health zones. When the lock-down was lifted, total visits and visits for infectious diseases and non-communicable diseases increased approximately twofold. Hospitals were more affected than health centres. Overall, the use of maternal health services and vaccinations was not significantly affected.
CONCLUSION: The COVID-19 pandemic resulted in important reductions in health service utilizsation in Kinshasa, particularly Gombe. Lifting of lock-down led to a rebound in the level of health service use but it remained lower than pre-pandemic levels.

be obtained from underground sources by exploitation of springs, tubewells, or dug wells. No filtration will then be needed. However, if sources are not available or cannot be developed, the use of surface water from streams, rivers, lakes or ponds becomes necessary. Usually these surface sources are polluted. The level of faecal contamination can be measured by use of the Oxfam/Delagua Water Test Kit (see Section C). Where a serious level of faecal pollution exists, it is essential firstly to try to reduce the cause of contamination, and secondly to treat the water to make it suitable for human consumption. The Filtration equipment provides a simple, long-term physical and biological treatment system that requires no chemicals (except small amounts of chlorine required during filter cleaning) and needs only simple regular maintenance

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 being 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. more
