4th edition
The WHO Laboratory Biosafety Manual (LBM) has been in broad use at all levels of clinical and public health laboratories, and other biomedical sectors globally, serving as a de facto global standard that presents best practices and sets trends in biosafety.
LBM encouraged countries t...o accept and implement basic concepts in biological safety and to develop national codes of practice for the safe handling of biological agents in laboratories within their geographical borders.
This fourth edition of the manual builds on the risk assessment framework introduced in the third edition. A thorough, evidence-based and transparent assessment of the risks allows safety measures to be balanced with the actual risk of working with biological agents on a case-by-case basis.
This novel evidence- and risk-based approach will allow optimised resource use and sustainable laboratory biosafety and biosecurity policies and practices that are relevant to their individual circumstances and priorities, enabling equitable access to clinical and public health laboratory tests and biomedical research opportunities without compromising safety.

Technical Update
Areas of Africa endemic for Buruli ulcer (BU), caused by Mycobacterium ulcerans, also have a high prevalence of human immunodeficiency virus (HIV), with adult prevalence rates between 1% and 5% (Maps). However, there is limited information on the prevalence of BU–HIV coinfection.... Preliminary
evidence suggests that HIV infection may increase the risk of BU disease (1–3). In the Médecins Sans Frontières project in Akonolinga, Cameroon, HIV prevalence was approximately 3–6 times higher among BU patients than the regional estimated HIV prevalence (2). Similarly in Benin and Ghana, BU
patients were 8 times and 3 times respectively more likely to have HIV infection than those without BU (1, 3). Further study is needed to clarify this association and enhance knowledge about the prevalence ofBU–HIV coinfection in endemic areas.

Antibiotics have been useful in fighting infectious diseases in our country for decades, but because of the overuse and misuse of these agents, an increasing number of organisms are now resistant to them. The Philippines, like other Southeast Asian countries, has already been encountering the many c...hallenges of antimicrobial resistance (AMR) which include increasing social and economic costs and rising patient mortality. Although considered a global threat, it is already an emerging local health concern which calls for an urgent collaboration among different sectors to provide solutions addressing this growing problem.

Interim guidance. 12 May 2021. The Continuity of essential health services: Facility Assessment Tool can be used by countries to rapidly assess the capacity of health facilities to maintain the provision of essential health services during the COVID-19 pandemic. It can help to alert the authorities ...and other stakeholders about where service delivery and utilization may require modification and/or investment. This assessment tool covers the following aspects of essential health services:
health workforce (numbers, absences, COVID-19 infections, health workforce management, training and support);
financial management and barriers;
service delivery and utilization (facility closures, changes in service delivery, community communication campaigns, changes in service utilization and catch-up strategies);
IPC capacities (protocols, safety measures, guidelines and the availability of personal protective equipment (PPE) for staff);
availability of therapeutics, diagnostics and supplies, and vaccine readiness; and
provision of COVID-19 primary care services.

Many critical questions remain about the effectiveness of COVID-19 vaccines in real-world settings. 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.

When situations occur in which unwanted events are rightly or wrongly connected with vaccination, they may erode confidence in vaccines and the authorities delivering them. This document presents the scientific evidence behind WHO’s recommendations on building and restoring confidence in vaccines ...and vaccination, both in ongoing work and during crises. The evidence draws on a vast reserve of laboratory research and fieldwork within psychology and communication. It examines how people make decisions about vaccination; why some people are hesitant about vaccination; and the factors that drive a crisis, covering how building trust, listening to and understanding people, building relations, communicating risk and shaping messages to the audiences may mitigate crises. This document provides a knowledge base for stakeholders who develop communication strategies or facilitate workshops on communication and trust-building activities in relation to vaccines and immunization, such as immunization programme units, ministries of health, public relations and health promotion units, vaccine safety communication trainers and immunization advisory bodies.

An overview of ethics and clinical ethics is presented in this review. The 4 main ethical principles, that is beneficence, nonmaleficence, autonomy, and justice, are defined and explained. Informed consent, truth-telling, and confidentiality spring from the ...principle of autonomy, and each of them is discussed. In patient care situations, not infrequently, there are conflicts between ethical principles (especially between beneficence and autonomy). A four-pronged systematic approach to ethical problem-solving and several illustrative cases of conflicts are presented. Comments following the cases highlight the ethical principles involved and clarify the resolution of these conflicts. A model for patient care, with caring as its central element, that integrates ethical aspects
(intertwined with professionalism) with clinical and technical expertise desired of a physician is illustrated

Tackling COVID-19 misinformation. Ensuring communities have access to lifesaving public health information from trusted sources and are not misled by misinformation is essential to ending the COVID-19 pandemic.
In an effort to empower doctors and nurses – some of the most effective and trusted... messengers of public health information – to actively address COVID-19 misinformation and build vaccine confidence globally, the WHO welcomes this social media toolkit for healthcare practitioners, developed by the Government of the United Kingdom.
This toolkit aims to provide healthcare workers with the tools, skills and content needed to effectively share authentic and reliable information online. Centered around three core vaccine confidence messages, Vaccine Safety, Vaccine Development and Vaccine Reducing Risk of Sickness; this toolkit sets out three approaches: creating your own posts, posting the images and videos provided in the toolkit, or resharing vaccine information from trusted sources.

In 2020, the COVID-19 pandemic impacted the world beyond imagination. To date, it has infected more than 135 million people, killed over 2.9 million people, and is projected to plunge up to 115 million people into extreme poverty.1 As countries have gone into lockdown, gender-based violence has incr...eased, unemployment has soared, and access to health care for the poorest and most vulnerable has been cut. COVID-19 has made people less likely to seek health care because they are afraid of getting infected with the virus. Fear and uncertainty surrounding COVID-19 have also increased stigma and discrimination. As frontline workers without enough access to personal protective equipment (PPE) risk their lives to treat patients, the virus pushes already fragile health systems to the brink.

The internationally recognized criteria for diagnosis of neurocysticercosis include a requirement for neuroimaging techniques, such as computerized tomography (CT) and/or magnetic resonance imaging (MRI), ideally supported by serology. These facilities are not available in all settings, especially i...n rural areas of low-income countries, making it difficult to identify and treat patients. Additionally, there is controversy about the role, type and duration of anthelmintic, antiinflammatory and antiepileptic drug (AED) treatments for different forms of neurocysticercosis.
These guidelines were developed to assist health-care providers in appropriate, evidence-based management of parenchymal neurocysticercosis. The guidelines do not address other forms of neurocysticercosis and do not include management of extraparenchymal disease (including cysticerci in the cerebral ventricles or subarachnoid space). The aim of the guidance is to improve decision-making to ensure appropriate patient care and to avoid misdiagnoses and inappropriate treatment of patients with neurocysticercosis.

Evidence shows that FGM can cause several physical, mental and sexual health complications in girls and women, and in newborns. Health-care providers play an important role in supporting girls and women living with FGM, and improving their health and well-being. They are in a unique position to infl...uence and change the attitudes of their patients about FGM.
WHO is committed to scaling up the health-sector response to address FGM prevention and care. One aspect is to strengthen the quality of FGM prevention and care services by building the capacity of health-care providers. Several guidance materials have been produced to target health-care providers. These include FGM content for training curricula, clinical guidelines and a clinical handbook.
This training manual complements previous publications by building person-centred communication skills specifically for FGM prevention.

As a result of Russia’s invasion of Ukraine, the people of Ukraine, especially the most vulnerable, are paying an enormous price. Lives and livelihoods are being lost, with more than ten million people forced from their homes— and their country—in search of safety. The war has unleashed catast...rophic damage to the country’s economy and threatens lasting increases in poverty and societal upheaval. The scale of the war and the devastation it has caused have jeopardized Ukraine’s hard-fought development gains, through destruction of production and property, disruption of trade, diminished investment due to amplified uncertainty, and erosion of human capita

Evidence-based guidelines are one of the most useful tools for improving public health and clinical practice. Their purpose is to formulate interventions based on strong evidence of efficacy, avoid unnecessary risks, use resources efficiently, reduce clinical variability and, in essence, improve hea...lth and ensure quality care, which is the purpose of health systems and services. These guidelines were developed following the GRADE methodology, with the support of a panel of clinical experts from different countries, all convened by the Pan American Health Organization. By responding to twelve key questions about the clinical diagnosis and treatment of dengue, chikungunya, and Zika, evidence-based recommendations were formulated for pediatric, youth, adult, older adult, and pregnant patients who are exposed to these diseases or have a suspected or confirmed diagnosis of infection. The purpose of the guidelines is to prevent progression to severe forms of these diseases and the fatal events they may cause. The recommendations are intended for health professionals, including general, resident, and specialist physicians, nursing professionals, and medical and nursing students, who participate in caring for patients with suspected dengue, chikungunya, or Zika. They are also intended for health unit managers and the executive teams of national arboviral disease prevention and control programs, who are responsible for facilitating the process of implementing these guidelines.

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.

Theodor Bilharz, a German professor of anatomy and chief of surgery at the Kasr El Ani Hospital of Cairo from 1850, first identified an infective organism, Distomum hematobium in 1851, which was renamed Schistosoma haematobium in 1858. It arose from a cestode worm, Hymenoleptis nana, lying in the sm...all colon of an Egyptian patient. He also discovered a trematode worm at the same time from an autopsy, thought to be the cause of urinary Schistosomiasis. Bilharz died from typhoid fever in 1862 at the age of 37. The Theodor Bilharz Research Institute in Giza, Egypt, stands as a tribute to him today. F. Milton published the first recorded peer-reviewed article report on Schistosomiasis in 1914.

Chagas disease (CD) is caused by the parasite Trypanosoma cruzi, and it is endemic in Central, South America, Mexico and the
South of the United States. It is an important cause of early mortality and morbidity, and it is associated with poverty and stigma. A third of
the cases evolve into chronic... cardiomyopathy and gastrointestinal disease. The infection is transmitted vertically and by blood/organ
donation and can reactivate with immunosuppression. Case identification requires awareness and screening programmes targeting the
population at risk (women in reproductive age, donors, immunocompromised patients). Treatment with benznidazole or nifurtimox is most
effective in the acute phase and prevents progression to chronic phase when given to children. Treating women antenatally reduces but does
not eliminate vertical transmission. Treatment is poorly tolerated, contraindicated during pregnancy, and has little effect modifying the
disease in the chronic phase. Screening is easily performed with serology. Migration has brought the disease outside of the endemic
countries, where the transmission continues vertically and via blood and tissue/organ donations. There are more than 32 million migrants
from Latin America living in non-endemic countries. However, the infection is massively underdiagnosed in this setting due to the lack of
awareness by patients, health authorities and professionals. Blood and tissue donation screening policies have significantly reduced
transmission in endemic countries but are not universally established in the non-endemic setting. Antenatal screening is not commonly
done. Other challenges include difficulties accessing and retaining patients in the healthcare system and lack of specific funding for the
interventions. Any strategy must be accompanied by education and awareness campaigns directed to patients, professionals and policy
makers. The involvement of patients and their communities is central and key for success and must be sought early and actively. This review
proposes strategies to address challenges faced by non-endemic countries
