These guidelines provide updated evidence-based recommendations on the priority HCV-related topics from the 2018 WHO Guidelines for the care and treatment of persons diagnosed with chronic hepatitis C infection and the 2017 WHO Guidelines on hepatitis B and C testing. These priority areas are:
... direct-acting antiviral (DAA) treatment of adolescents and children ages ≥3 years of age
simplified HCV service delivery (decentralization, integration and task sharing)
HCV diagnostics – use of point-of-care (POC) HCV ribonucleic acid (RNA) assays and reflex HCV RNA testing.
These guidelines also update existing chapters without new recommendations, such as the inclusion of new manufacturers’ protocols on the use of dried blood spot (DBS) for HCV RNA testing and new data to inform the limit of detection for HCV RNA assays as a test of cure, in addition to their use for diagnosis.

Addressing comorbidities and risk factors for TB is a crucial component of Pillar one of the End TB Strategy, which focuses on integrated patient-centred care and prevention, including action on TB and comorbidities. The Framework for collaborative action on TB and comorbidities aims to support coun...tries in the evidence-informed introduction and scale-up of holistic people-centred services for TB, comorbidities and health-related risk factors, with the goal of comprehensively addressing TB and other co-existing health conditions. It should be used in conjunction with relevant WHO guidelines. The Framework is intended for use by people working in ministries of health, other relevant line-ministries, policymakers, international technical and funding organizations, researchers, nongovernmental and civil society organizations, as well as primary care workers, specialist health practitioners, and community health workers who support the response to TB and comorbidities in both the public and private sectors.

The purpose of this book is to provide an overview of Buruli ulcer (Mycobacterium ulcerans infection) for the medical and scientific communities and the general public alike.
Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim...ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

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.

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.

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.

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.

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.
