This report investigates the impact of potential misclassification of samples on HIV prevalence estimates for 23 surveys conducted from 2010-2014. In addition to visual inspection of laboratory results, we examined how accounting for potential misclassification of HIV status through Bayesian latent ...class models affected the prevalence estimates. Two types of Bayesian models were specified: a model that only uses the individual dichotomous test results and a continuous model that uses the quantitative information of the EIA (i.e., the signal-to-cutoff values). Overall, we found that adjusted prevalence estimates matched the surveys’ original results, with overlapping uncertainty intervals. This suggested that misclassification of HIV status should not affect the prevalence estimates in most surveys. However, our analyses suggested that two surveys may be problematic. The prevalence could have been overestimated in the Uganda AIDS Indicator Survey 2011 and the Zambia Demographic and Health Survey 2013-14, although the magnitude of overestimation remains difficult to ascertain. Interpreting results from the Uganda survey is difficult because of the lack of internal quality control and potential violation of the multivariate normality assumption of the continuous Bayesian latent class model. In conclusion, despite the limitations of our latent class models, our analyses suggest that prevalence estimates from most of the surveys reviewed are not affected by sample misclassification.

This document updates the 2009 ECDC guidance on chlamydia control in Europe. It was developed by a technical expert group which conducted a critical review of the scientific evidence on the epidemiology of chlamydia and the effectiveness of screening programmes.
The aim of this guidance is to suppo...rt Member States to develop, implement or improve strategies for chlamydia control. This guidance describes the current evidence base behind the proposed options, highlights key gaps in knowledge, and suggests effective options for national chlamydia control strategies. It is directed primarily at policy advisors but should also be useful for programme managers and experts in sexual health.

It is too early to know the full impact of COVID-19 on Africa. To date the experience has been varied. There are causes for concern, but also reasons for hope. Early estimates were pessimistic regarding the pandemic’s impact on the continent. But the relatively low numbers of COVID-19 cases report...ed thus far have raised hopes that African countries may be spared the worst of the pandemic. While the virus is present in all African countries, most countries have recorded fewer than 1,000 cases. The African Union acted swiftly, endorsing a joint continental strategy in February, and complementing efforts by Member States and Regional Economic Communities by providing a public health platform.

n response to the outbreak, the Africa Centres for Disease Control and Prevention (Africa CDC) has been supporting African Union Member States in responding to the COVID-19 pandemic through a variety of interventions such as non-pharmaceutical interventions, quarantine, testing, isolation, contact t...racing, and clinical management. The Test to Treat guideline aims to increase continental testing efforts and reduce COVID-19 transmission in Africa and put-up response measures to control the impact of the virus, both to limit spread and to reduce substantially the risks of severe health outcomes related to COVID-19 infection. These countermeasures include highly effective vaccines and boosters, rapid testing options for monitoring exposure, and effective therapeutic options for both pre-exposure prevention and treatment of mild-to-moderate disease, oxygen therapy for moderate-severe disease, all of which can potentially be updated efficiently as new variants emerge that may affect the effectiveness of the available tools.

Background
The core clinical symptoms of addiction include an enhanced incentive for drug taking (craving), impaired self-control (impulsivity and compulsivity), emotional dysregulation (negative mood) and increased stress reactivity. Symptoms related to impaired self-control involve reduced activi...ty in anterior cingulate cortex (ACC), adjacent prefrontal cortex (mPFC) and other brain areas. Behavioral training such as mindfulness meditation can increase the function of control networks including those leading to improved emotion regulation and thus may be a promising approach for the treatment of addiction.
Methods
In a series of randomized controlled trials (RCTs), we tested whether increased ACC/mPFC activity is related to better self-control abilities in executive functions, emotion regulation and stress response in healthy and addicted populations. After a brief mindfulness training (Integrative Body-Mind Training, IBMT), we used the Positive and Negative Affect Schedule (PANAS) and Profile of Mood States (POMS) to measure emotion regulation, salivary cortisol for the stress response and fMRI for brain functional and DTI structural changes. Relaxation training was used to serve as an active control.
Results
In both smokers and nonsmokers, improved self-control abilities in emotion regulation and stress reduction were found after training and these changes were related to increased ACC/mPFC activity following training. Compared with nonsmokers, smokers showed reduced ACC/mPFC activity in the self-control network before training, and these deficits were ameliorated after training.
Conclusions
These results indicate that promoting emotion regulation and improving ACC/mPFC brain activity can help for addiction prevention and treatment.

AMR is a serious and growing global problem. A WHO report released in 2014 stated that this serious threat is no longer a prediction for the future it is happening now in every region of the world and has potential to affect anyone, of any age in any community – a real threat to the public health.... The coming together of the various important stakeholders to develop this document is the testimony of their agreement of how serious is the issue at hand and their intentions to combat AMR is translated into an Action Plan. WHO also reported that there are about 2 million people in the US are infected with the AMR organism while 23,000 die annually from AMR infections. Fiji is just 10 hours journey away from the United States of America therefore Fiji must act now to keep our population safe from AMR organisms.

Many features of the environment have been found to exert an important influence on cardiovascular disease (CVD) risk, progression, and severity. Changes in the environment due to migration to different geographic locations, modifications in lifestyle choices, and shifts in social policies and cultu...ral practices alter CVD risk, even in the absence of genetic changes. Nevertheless, the cumulative impact of the environment on CVD risk has been difficult to assess
and the mechanisms by which some environment factors influence CVD remain obscure. Human environments are complex; and their natural, social and personal domains are highly variable due to diversity in human ecosystems, evolutionary histories, social structures, and individual choices. Accumulating evidence supports the notion that ecological features such as the diurnal cycles of
light and day, sunlight exposure, seasons, and geographic characteristics of the natural environment such altitude, latitude and greenspaces are important determinants of cardiovascular health and CVD risk. In highly developed societies, the influence of the natural environment is moderated by the physical characteristics of the social environments such as the built environment
and pollution, as well as by socioeconomic status and social networks. These attributes of the
social environment shape lifestyle choices that significantly modify CVD risk. An understanding
of how different domains of the environment, individually and collectively, affect CVD risk could
lead to a better appraisal of CVD, and aid in the development of new preventive and therapeutic
strategies to limit the increasingly high global burden of heart disease and stroke.

The Event-based Surveillance Framework is intended to be used by authorities and agencies responsible for
surveillance and response. This framework serves as an outline to guide stakeholders interested in implementing
event-based surveillance (EBS) using a multisectoral, One Health approach. To ...that end, the document is arranged
in interlinked chapters and annexes that can be modified and adapted, as needed, by users.
This is a revised version of the original “Framework for Event-based Surveillance” that was published in 2018. This
framework does not replace any other available EBS materials, but rather builds on existing relevant or related
documents and serves as a practical guide for the implementation of EBS in Africa. This framework is aligned with
the third edition of the WHO Joint External Evaluation for the following indicators: strengthened early warning
surveillance systems that are able to detect events of significance for public health and health security (Indicator
D2.1); improved communication and collaboration across sectors and between National, intermediate and local
public health response levels of authority regarding surveillance of events of public health significance (Indicator
D2.2); and improved national and intermediate-level capacity to analyse data (Indicator D2.3). As countries begin
to implement and demonstrate EBS functionality they will ensure an increase in JEE scores and progress towards
meeting the requirements outlined in the IHR3F
Additionally, in African Union Member States that have adopted the Integrated Disease Surveillance and
Response (IDSR) strategy, this document is a complement to and can enhance the implementation of IDSR,
especially for the 3rd edition (2019) that includes components related to EBS.

Background: Data on burden of peripheral artery disease (PAD) and its attributable risk factors are valuable for policymaking. We aimed to estimate the burden and risk factors for PAD from 1990 to 2019.
Methods: We extracted the data on prevalence, incidence, death, years lived with disability (YLD...s), and years of life lost (YLLs) from the Global Burden of Disease Study 2019 to measure PAD burden. Moreover, the attributable burden to PAD risk factors was also estimated.
Results: Globally, in 2019, 113,443,017 people lived with PAD and 10,504,092 new cases occurred, resulting in 74,063 deaths, 500,893 YLDs, and 1,035,487 YLLs. The absolute numbers of PAD prevalent and incident cases significantly increased between 1990 and 2019, contrasting with the decline trends in age-standardized prevalence and incidence rates. However, no statistically significant changes were detected in the global age-standardized death or YLL rates. The burden of PAD and its temporal trends varied significantly by location, gender, age group, and social-demographic status. Among all potentially modifiable risk factors, age-standardized PAD deaths worldwide were primarily attributable to high fasting plasma glucose, followed by high systolic blood pressure, tobacco, kidney dysfunction, diet high in sodium, and lead exposure.
Conclusion: PAD remained a serious public health problem worldwide. More strategies aimed at implementing cost-effective interventions and addressing modifiable risk factors should be carried out, especially in regions with high or increasing burden.

The world’s climate is changing. There is scientific consensus that since 1980 global temperatures have increased by almost 1°C. Most people experience climate change through extreme weather events, new and re-emerging infectious disease, and the long term effects of sea level rise, impoverishmen...t and armed conflict. This 30 minute film describes the range of morbidity and mortality of climate change related phenomena in six countries around the world.
The film describes the ways in which climate change will have – is already having – significant effects on human health. These effects are unequally distributed in terms of geographic location, social status, access to power or resources, and benefit from energy.

Latin America and the Caribbean is characterized by a matrix of social inequality whose axes —such as
socioeconomic stratum, gender, stage in the life cycle, ethnicity and race, territory, disability, and immigration
status— create multiple, often concurrent, situations of exclusion and discri...mination. The coronavirus
disease (COVID-19) pandemic has exacerbated wide social gaps and it is no coincidence that Latin America
and the Caribbean is one of the regions in which the health and socioeconomic impacts of the pandemic have
been the most severe, which shows that the costs of inequality are unsustainable

The rapid development of effective Covid-19 vaccines in 2020 gave hope to the world in the darkest days of the deadly pandemic. However, the vaccine roll-out has been massively skewed towards wealthy nations. While rich states have hoarded vaccines, companies have also played a decisi...ve role in restricting fair access to a life-saving health product. This report focuses on six leading vaccine developers, AstraZeneca, BioNTech, Johnson & Johnson, Moderna, Novavax and Pfizer, assessing each company’s human rights policy, pricing structure, records on intellectual property, knowledge and technology sharing, allocation of available vaccine doses and transparency.

On 19 August 2016, the former UN Secretary-General announced a new approach to cholera in Haiti, consisting of two tracks. Track 1 focuses on reducing cholera transmission, improving access to care, and addressing water, sanitation, and health system issues. Track 2 aims to provide material assistan...ce to those most affected by cholera. The Secretary-General urged Member States to show solidarity with Haiti by increasing contributions. The UN General Assembly, in resolution 71/161, recognized the UN's moral responsibility to cholera victims and called for support to eliminate cholera and address its victims' suffering. The Secretary-General was requested to provide an update on the progress of this approach.

KEY MESSAGES
Always talk to a GBV specialist first to understand what GBV services are available in your area. Some services may take the form of hotlines, a mobile app or other remote support.
Be aware of any other available services in your area. Identify services provided by humanitarian pa...rtners such as health, psychosocial support, shelter and non-food items. Consider services provided by communities such as mosques/ churches, women’s groups and Disability Service Organizations.
Remember your role. Provide a listening ear, free of judgment. Provide accurate, up-to-date information on available services. Let the survivor make their own choices. Know what you can and cannot manage. Even without a GBV actor in your area, there may be other partners, such as a child protection or mental health specialist, who can support survivors that require additional attention and support. Ask the survivor for permission before connecting them to anyone else. Do not force the survivor if s/he says no.
Do not proactively identify or seek out GBV survivors. Be available in case someone asks for support.
Remember your mandate. All humanitarian practitioners are mandated to provide non-judgmental and non-discriminatory support to people in need regardless of: gender, sexual orientation, gender identity, marital status, disability status, age, ethnicity/tribe/race/religion, who perpetrated/committed violence, and the situation in which violence was committed. Use a survivor-centered approach by practicing:
Respect: all actions you take are guided by respect for the survivor’s choices, wishes, rights and dignity.
Safety: the safety of the survivor is the number one priority.
Confidentiality: people have the right to choose to whom they will or will not tell their story. Maintaining confidentiality means not sharing any information to anyone.
Non-discrimination: providing equal and fair treatment to anyone in need of support.
If health services exist, always provide information on what is available. Share what you know, and most importantly explain what you do not. Let the survivor decide if s/he wants to access them. Receiving quality medical care within 72 hours can prevent transmission of sexually transmitted infections (STIs), and within 120 hours can prevent unwanted pregnancy.
Provide the opportunity for people with disabilities to communicate to you without the presence of their caregiver, if wished and does not endanger or create tension in that relationship.
If a man or boy is raped it does not mean he is gay or bisexual. Gender-based violence is based on power, not someone’s sexuality.
Sexual and gender minorities are often at increased risk of harm and violence due to their sexual orientation and/or gender identity. Actively listen and seek to support all survivors.
Anyone can commit an act of gender-based violence including a spouse, intimate partner, family member, caregiver, in-law, stranger, parent or someone who is exchanging money or goods for a sexual act.
Anyone can be a survivor of gender-based violence – this includes, but isn’t limited to, people who are married, elderly individuals or people who engage in sex work.
Protect the identity and safety of a survivor. Do not write down, take pictures or verbally share any personal/identifying information about a survivor or their experience, including with your supervisor. Put phones and computers away to avoid concern that a survivor’s voice is being recorded.
Personal/identifying information includes the survivor’s name, perpetrator(s) name, date of birth, registration number, home address, work address, location where their children go to school, the exact time and place the incident took place etc.
Share general, non-identifying information
To your team or sector partners in an effort to make your program safer.
To your support network when seeking self-care and encouragement.
