Gambiense human African trypanosomiasis is a deadly infectious disease affecting West and Central Africa, South Sudan and Uganda, and transmitted between humans by tsetse flies. The disease has caused several major epidemics, the latest one in the 1990s. Thanks to recent innovations such as rapid di...agnostic tests for population screening, a single-dose oral treatment and a highly efficient vector control strategy, interruption of transmission of the causative parasite is now within reach. If indeed gHAT has an exclusively human reservoir, this could even result in eradication of the disease. Even if there were an animal reservoir, on the basis of epidemiological data, it plays a limited role. Maintaining adequate postelimination surveillance in known historic foci, using the newly developed tools, should be sufficient to prevent any future resurgence.

For the molecular diagnosis of Chagas disease by real-time PCR (polymerase chain reaction), optimization of diagnostic accuracy is desirable. The detection limit of real-time PCR assays for the diagnosis of Trypanosoma cruzi in human serum is affected by various influences including the choice of th...e nucleic acid extraction assay. In this study, three nucleic acid extraction assays were compared regarding their influence on the sensitivity of a T. cruzi-specific real-time PCR with 62 reference sera containing T. cruzi target DNA (deoxyribonucleotide acid). More than 95% of the positive sera were correctly identified after all three nucleic acid extraction strategies with a detection rate ranging from 96.8% (60/62) for the worst assay to 100% (62/62) for the best one. A matched pairs analysis for the comparison of the cycle threshold (Ct) values obtained with the 59 reference samples with positive real-time PCR results after all three nucleic acid extraction schemes indicated differences in a range of about 3 Ct steps. Summarized, all three compared nucleic acid extraction schemes were basically suitable for T. cruzi-specific PCR from serum with some minor differences. However, in the case of low quantities of circulating parasite DNA in the serum of a patient with Chagas disease, even minor effects can make a difference in the individual diagnosis.

Chagas disease (CD) is endemic in the Americas, being present in 21 countries, where it affects about 6 million
people.(1) With such relevant numbers of people affected and disability adjusted life years lost, CD is a poverty-related
and poverty-promoting disease.
Although data describe a relevan...t ongoing public health problem for the American continent, significant results
in the interruption of transmission has been achieved by coordinated multi-country programs. In particular, the
Southern Cone Initiative (SCI), officially formalised in November 1991 by the Ministers of Health of Argentina, Brazil, Bolivia, Chile, Paraguay and Uruguay, has shown how a well-designed control program can significantly reduce
CD transmission.(2) Before this initiative, in these countries, there were 11 million infected persons and 50 million at
risk, 62% of the infected individuals of the whole continent.

The World Health Organization (WHO) and the global community of countries, partners, donors, technical experts, scientists and field implementation teams continue to work towards the ultimate goal of a world free of the burden of neglected tropical diseases (NTDs). This work is described in the NTD ...road map 2021–2030, WHO’s blueprint to drive global efforts in the fight against NTDs in the context of the United Nations Sustainable Development Goals. These goals encompass a vision of a world population for whom equality of opportunity and of health are fundamental.
Within this context, and during the two years since the launch of the road map (2021–2022), progress has been made. Nevertheless, hindrances towards achieving the targets for 2030 have arisen and work to overcome these obstacles continues. These endeavours have also revealed the scale of the task still facing the global NTD community.
Disruption as a result of the COVID-19 pandemic has continued to afflict longstanding and new programmes alike, while other entrenched issues have re-emerged in new and challenging ways. The global NTD community is also confronted with a changing, multi-dimensional funding landscape as donors reassess priorities and adapt to new ways of working, as well as a challenging and unpredictable international context. As a result, progress in controlling, eliminating or eradicating NTDs has not been as far-reaching as expected.

PLoS Neglected Tropical diseases August 16, 2021 https://doi.org/10.1371/journal.pntd.0009697
Chagas disease, also known as American trypanosomiasis, is a neglected tropical disease transmitted by triatomine insects, first identified in 1909. Chagas disease affects approximately 6–7 million peop...le globally and is highly prevalent in Latin America where most cases are reported. However, there is increasing evidence that Chagas disease is now an important public health issue outside the “classical” endemic countries due to population migration. Our understanding of Chagas disease, including its pathologies and factors relating to progression, remains to date limited, and is also challenged by lack of diagnosis and highly effective treatment. This systematic review aims to describe studies with Chagas patients receiving antiparasitic treatment. Databases were searched for relevant studies published after 1997, and the results of these searches were screened.

Atlas of African Health Statistics 2022: Health situation analysis of the WHO African Region
Since 2019, we have been implementing Phase 2 of the regional Transformation Agenda, which informs and aligns with the global WHO Transformation, to ensure WHO is accountable, driven by re- sults and provid...ing value for money in the pursuit of better health. Our global priority in this period is to contribute to delivering on the triple billion targets of expanding universal health coverage, protecting people from emergencies, and promoting health and well-being for people across the Region.
This year’s Atlas of African Health Statistics is being produced in the context of the COVID-19 pandemic that we have been expe- riencing for over two years. The ongoing coronavirus pandemic, together with other health emergencies in the WHO African Re- gion, is yet again testing the strength and resilience of our health systems. Indeed, the impact of COVID-19 is visible in the disruption of services. The report also presents the latest data for more than 50 health-related indicators of the Sustainable Development Goals and WHO’s “triple billion” targets and provides comprehensive country-level statistics using the results chain of the AFRO frame- work of actions for strengthening health systems to achieve UHC and the health-related SDGs.

The world faces grave consequences from the lack of available mental health services and treatment. Mental illness impacts every country, culture and community, with the World Health Organization (WHO) stating that 10% of the global burden of disease is related to mental, neurological and substance ...use disorders. In low-and middle-income countries, more than 75% of people with mental disorders receive no treatment at all for their disorder. During 2020, as a result of the global pandemic, 93% of countries reported their mental health services were either halted or interrupted (WHO, 2020e). WHO reported a 25% increase in depression and anxiety alone during the pandemic. The Organisation for Economic Co-operation and Development estimates depression and anxiety cost the global economy US $1 trillion dollars a year. All nurses have a health care role in mental health and substance use. ICN strongly advocates for the investment of further education and professional development in this area in order to support individuals and communities achieve the highest attainable standard of health which includes
physical, mental and social wellbeing.

EQUIP: Ensuring Quality in Psychological Support is a joint WHO/UNICEF project to improve the competence of helpers and the consistency and quality of training and service delivery. The EQUIP platform makes freely available competency assessment tools and e-learning courses to support governments, t...raining institutions, and non-governmental organizations, both in humanitarian and development settings, to train and supervise the workforce to deliver effective psychological support to adults and children.
EQUIP enhances training and supervision for improved mental health and psychosocial support services.
EQUIP used a consensus-building approach including key stakeholders to develop the evidence-informed competency-based training materials and guidance, as well as the competency assessment tools. These resources have been tested in Ethiopia, Jordan, Kenya, Lebanon, Nepal, Peru, Uganda and Zambia, with results demonstrating training improvements in groups that used the EQUIP platform. For example, use of EQUIP in Lebanon with children and adolescents led to an increase in mastery of core helping skills compared to standard training approaches.

Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

9 March 2022, Timely and accurate diagnostic testing for SARS-CoV-2 is an essential part of a comprehensive COVID-19 response strategy. Ag-RDTs can be performed by individuals in which they collect their own specimen, perform a simple rapid test and interpret their test result themselves at a time a...nd place of their choosing, termed COVID-19 self-testing. This interim guidance provides a new recommendation that COVID-19 self-testing, using SARS-CoV-2 Ag-RDTs, should be offered as part of SARS-CoV-2 testing services. It also includes implementation considerations that can guide decisions on whether, and how, to adopt self-testing in different contexts, including the populations being prioritized; the disease prevalence in that population; and the impact on accessibility of testing, health care services and result reporting.

A full-scale military attack (invasion) of Ukraine was started by Russia in the night of February 23/24, 2022. Cities, towns and other targets in all regions of Ukraine have been shelled or attacked with rockets, and columns of military vehicles have been invaded the country from three directions (n...orth, east and south). Fighting continues across all regions with Russian forces capturing cities along the south coast but facing tougher resistance in the northern parts of the country. Residential areas in cities such as Kharkiv, Kyiv and Mykolaiv have been shelled and destroyed, with many lives have been lost. Ongoing negotiations between the governments of Ukraine and Russia have yielded no results in bringing a ceasefire or end to the conflict.

This guidance addresses rationale, risk-based scenarios, practical considerations prior to adoption of the self-testing products, quality assurance, safety and ethical considerations, and data management considerations for COVID-19 self-testing. The Africa CDC recommends the use of rapid antigen sel...f-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

The World Health Organization and the Global Fund to Fight AIDS, Tuberculosis and Malaria are part of a group of agencies working together to accelerate progress towards the health-related SDGs through the Global Action Plan for Healthy Lives and Well-being for All. Understanding patterns of inequal...ities in these diseases is essential for taking strategic, evidence-informed action to realize our shared vision of ending the epidemics of HIV, TB and malaria.
This report presents the first comprehensive analysis of the magnitude and patterns of socioeconomic, demographic and geographic inequalities in disease burden and access to services for prevention and treatment.
The results confirm there have been improvements in service coverage and decreased disease burden at the national level over the past decade. But they also reveal an uncomfortable reality: unfair inequalities between population subgroups within countries are widespread and have remained largely unchanged over the past decade. For some disease indicators, inequalities are even worsening.
Moreover, the report points to the persistent lack of available data to fully understand inequality patterns in HIV, TB and malaria. Collecting data to improve the monitoring of inequalities in these diseases is vital to develop targeted responses for impact.
There are, encouragingly, isolated successes in reducing inequities. Change is possible when deliberate action is taken to reach disadvantaged populations.

Food and nutrition security in the Democratic Republic of the Congo is subject to the relentless impact of conflict, epidemics and climate events that have persisted in the country for decades, further compounded by the global COVID-19 pandemic. Lack of infrastructure and investment in agriculture, ...health and human capital development combine to impede progress towards the achievement of Sustainable Development Goals 2 and 17. While there are several legal instruments and policies that promote food and nutrition security, poor coordination, weak national capacity and exponential population growth present serious obstacles to the achievement of zero hunger. Political instability and siloed sectoral responses to humanitarian and development needs have also affected results to date.

Background: Healthcare workers’ mental health was affected by SARS-CoV-2 pandemic.
Aim: To evaluate healthcare workers’ mental health and its associated factors during the pandemic in Chile. Material and Methods: An online self-reported questionnaire was designed including the Goldberg Healt...h Questionnaire, the Patient Health
Questionnaire, (PHQ-9), and the Columbia-Suicide Severity Rating Scale among other questions. It was sent to 28,038 healthcare workers.
Results: The questionnaire was answered by 1,934 participants, with a median age of 38 years (74% women). Seventy five percent were professionals, and 48% worked at a hospital. Fifty nine percent of respondents had a risk of having a mental health disorder, and 73% had depressive symptoms. Significant associations were found with sex, workplace, and some of the relevant experiences during the pandemic. Fifty one
percent reported the need for mental health support, and 38% of them received it.
Conclusions: There is a high percentage of health workers with symptoms of psychological distress, depression, and suicidal ideas. The gender approach is essential to understand the important differences found. Many health workers who required mental health care did not seek or received it.
