During the year 2022, COVID-19 continued to be a significant challenge in Eritrea as in many other countries across the world. As COVID-19 devastated communities around the world, WHO worked with the MoH to strengthen the National and Sub-National health systems in order to meet community needs and ...mitigate the devastation during the pandemic and beyond.
One of the major achievements in the year 2022 was the beginning of the journey towards validation of
the elimination of mother to child transmission of HIV, syphilis, and hepatitis B. This is the culmination of years
of commitment and determination by the political leadership, national and international partnerships to
reduce the associated indices to levels that qualify for elimination.

In 2005, the World Health Organization (WHO) recognized Chagas disease (CD; Trypanosoma cruzi infection) as a neglected tropical disease (NTD) [1] and included it into the global plan to combat NTDs [2]. The Target 3.3 of the United Nations Sustainable Development Goals (UN/SDG) aims at ending the e...pidemics of NTDs by 2030 [3]. Mother-to-child (congenital/connatal) transmission is currently the main mode of transmission of T. cruzi over blood transfusions and organ transplantations in vector-free areas within and outside Latin America (LA). Based on recent demonstrations that congenital transmission can be prevented [4–7], WHO has shifted its objective, in 2018, from control to elimination of congenital CD (cCD).

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.

.Chronic manifestations of Chagas disease present as disabling and life-threatening condi-tions affecting mainly the cardiovascular and gastrointestinal systems. Although meaningful research has outlined the different molecular mech...anisms underlying Trypanosoma cruzi’s infection and the host-parasite interactions that follow, prompt diagnosis and treatment remain a challenge, particu-larly in developing countries and also in those where the disease is considered non-endemic. This review intends to present an up-to-date review of the parasite’s life cycle, genetic diversity, virulence factors, and infective mechanisms, as well as the epidemiology, clinical presentation, diagnosis, and treatment options of the main chronic complications of Chagas disease.

SECOND MEETING REPORT
DECATUR, GA, USA, 26 JUNE 2016
The main objective of the malaria prevention and control programme in Somalia is to prevent mortality and reduce morbidity due to malaria. The groups most vulnerable to the disease, children aged under 5 years and pregnant women, are especially targeted. Effective case management - early diagnosis a...nd treatment - is a critical component of malaria prevention and control. To achieve the main objective of reducing malaria morbidity and prevention of malaria mortality, the availability of safe, effective, affordable and accessible anti-malarial drugs is a prerequisite.

The Practical manual on laboratory strengthening, 2022 update provides practical guidance on implementation of WHO recommendations and best practices for TB laboratory strengthening. It is an updated version of the GLI Practical Guide to Laboratory Strengthening published in 2017 and provides the la...test practical guidance on use of newly recommended diagnostics as well as guidance in key technical areas, including quality assurance and quality management systems, specimen collection and registration, procurement and supply-chain management, diagnostic connectivity, biosafety, data management, human resources, strategic planning, and model algorithms. The key changes are:
inclusion of recent or updated WHO recommendations for tests to diagnose TB and detect drug resistance;
alignment with the latest WHO critical concentrations for phenotypic drug-susceptibility testing (DST) and the new definitions of pre-XDR-TB and XDR-TB;
updated information on building quality-assured TB testing and management capacity using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) approach (Score-TB package1);
updated information on assessing, analysing and optimising TB diagnostic networks; and
updated information on the use of next-generation sequencing (NGS) to detect mutations associated with drug resistance for surveillance purposes.
The document also provides references to resources and tools relevant for work on laboratory strengthening.

This document focuses on making recommendations for the diagnosis and treatment of Chagas disease, an infection caused by Trypanosoma cruzi, the protozoan agent of a systemic parasitic disease. Methodology: These clinical practice guidelines were prepared following the WHO handbook for guideline dev...elopment (5). A multidisciplinary development group was formed, comprised of thematic experts, epidemiologists, methodologists, and users. Since there were no existing guidelines that could be adapted, the guidelines were developed from scratch.

International commitment to eliminate trachoma as a public health problem worldwide is supported by resolution WHA51.11 of the World Health Assembly .1 Important progress towards this goal has been made by harnessing the mostly informal relationships that exist between partners including Member Stat...es, the World Health Organization (WHO), academic institutions, donors and nongovernmental organizations. Recognizing that work remains to be done and that the 2020 target2 for elimination is rapidly approaching, in February 2015 the WHO Department of Control of Neglected Tropical Diseases convened a group of academic institutions that had for many years helped WHO to implement its mandate on trachoma and to work towards establishing a Network of WHO collaborating centres (WHOCCs) for Trachoma. The report of that meeting has been published.

The leishmaniases are a group of diseases caused by Leishmania spp., which occur in cutaneous, mucocutaneous and visceral forms. They are neglected tropical diseases (NTDs), which disproportionately affect marginalized populations who have limited access to health care. HIV co-infected patients with... Leishmania infection are highly infectious to sandflies, and an increase in the coinfection rate in an endemic area is likely to increase the effective infective reservoir.

Antimicrobial resistance (AMR) is a threat to global health and development and it contributes to millions of deaths worldwide each year. Inappropriate use and overuse of antibiotics are driving an increase in AMR and have a detrimental impact on the effectiveness of these critical medicines. Throug...h the Global Action Plan on AMR, WHO is working to improve the surveillance of antimicrobial resistance and reduce inappropriate antibiotic consumption.
There is a recognized need for high-quality resources to improve antibiotic prescribing globally. To address this need, a pragmatic approach was taken by WHO to develop actionable guidance for empiric antibiotic use.
The WHO AWaRe (Access, Watch, Reserve) antibiotic book provides concise, evidence-based guidance on the choice of antibiotic, dose, route of administration, and duration of treatment for more than 30 of the most common clinical infections in children and adults in both primary health care and hospital settings. The information included in the book supports the recommendations for antibiotics listed on the WHO Model Lists of Essential Medicines and Essential Medicines Children and the WHO AWaRe classification of antibiotics.
The WHO AWaRe antibiotic book is accompanied by summary infographics for each infection for both adults and children that provide a quick-reference guide for health care workers at the point of care.

It is Zika virus (ZIKV) that most often causes these neurological effects it appears to be the only arbovirus than can cause congenital malformations such as microcephaly. In any case, more scientific tests are needed to establish the causal relationship between the virus and this malformation (7-10...).
This document is a practical tool designed to help health workers improve clinical diagnosis and provide timely care for patients infected
with the dengue, chikungunya, or Zika virus. It is intended mainly for
health workers in primary care facilities where laboratory diagnosis of
arboviruses is not always available. However, this guide may also be
very useful in hospitals that provide second- and third-level care, as it
describes the clinical manifestations of each of the three most important
arboviral diseases currently found in the Region, the elements for
differential diagnosis, and their clinical behavior.

Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

Many countries have made significant progress in the implementation of World Health Organization recommended preventive chemotherapy strategy, to eliminate lymphatic filariasis (LF). However, pertinent challenges such as the existence of areas of residual infections in disease endemic districts pose... potential threats to the achievements made. Thus, this study was undertaken to assess the importance of these areas in implementation units (districts) where microfilaria (MF) positive individuals could not be found during the mid-term assessment after three rounds of mass drug administration.
