Contact tracing for COVID-19 is the process of identifying, assessing, and managing people who have been exposed to someone who has been infected with the SARS-CoV-2 virus, while quarantine is the separation of contacts from other people after exposure to a probable or confirmed case of SARS-CoV-2 i...nfection. In the context of growing global population immunity from COVID-19 vaccination and past SARS-CoV-2 infection, WHO recommends that identification, contact, quarantine and follow-up should be prioritized for individuals at high risk who have been in contact with a confirmed or probable case of SARS-CoV-2 infection, rather than targeting all contacts. This updated guidance also introduces shorter recommended quarantine periods, including the ability to further shorten quarantine through the use of testing. National and local health authorities should use risk-based approaches to contact tracing and quarantine that include reviewing and adjusting to their local circumstances and disease epidemiology, population immunity, their health system’s capacities, and risk tolerance.

Hendra virus (HeV) continues to pose a serious public health concern as spillover events occur sporadically. Terminally ill horses can exhibit a range of clinical signs including frothy nasal discharge, ataxia or forebrain signs. Early signs, if detected, can include depression, inappetence, colic o...r mild respiratory signs. All unvaccinated ill horses in areas where flying foxes exist, may potentially be infected with HeV, posing a significant risk to the veterinary community. Equivac® HeV vaccine has been fully registered in Australia since 2015 (and under an Australian Pesticides and Veterinary Medicines Authority special permit since 2012) for immunization of horses against HeV and is the most effective and direct solution to prevent disease transmission to horses and protect humans. No HeV vaccinated horse has tested positive for HeV infection. There is no registered vaccine to prevent, or therapeutics to treat, HeV infection in humans. Previous equine HeV outbreaks tended to cluster in winter overlapping with the foaling season (August to December), when veterinarians and horse owners have frequent close contact with horses and their bodily fluids, increasing the chance of zoonotic disease transmission. The most southerly case was detected in 2019 in the Upper Hunter region in New South Wales, which is Australia's Thoroughbred horse breeding capital. Future spillover events are predicted to move further south and inland in Queensland and New South Wales, aligning with the moving distribution of the main reservoir hosts. Here we (1) review HeV epidemiology and climate change predicted infection dynamics, (2) present a biosecurity protocol for veterinary clinics and hospitals to adopt, and (3) describe diagnostic tests currently available and those under development. Major knowledge and research gaps have been identified, including evaluation of vaccine efficacy in foals to assess current vaccination protocol recommendations.

There is a broad consensus nowadays that the Earth is warming up as a result of greenhouse gas emissions caused by anthropogenic activities. It is also clear that current trends in the fields of energy, development and population growth will lead to continuous and ever more dramatic climate change. ...This is bound to affect the fundamental prerequisites for maintaining good health: clean air and water, sufficient food and adequate housing. The planet will warm up gradually, but the consequences of the extreme weather conditions such as frequent
storms, floods, droughts and heat-waves will have sudden onset and acute repercussions. It is widely accepted that climate change will have an impact on the spread of infectious diseases in Europe, which is likely to bring about new public health risks in the majority of cases. Transmission of infectious diseases depends on a number of factors, including climate and environmental elements. Foodborne and waterborne diseases, for instance, are associated with high temperatures. Disease-transmitting vectors (e.g. mosquitoes, sandflies and ticks) are highly sensitive to climate conditions, including temperature and humidity; their geographical distribution will widen as climate conditions change, potentially allowing them to spread into regions where they are not currently able to live.
The primary purpose of this manual on climate change and infectious diseases is to raise the awareness and the level of knowledge of health workers at national, regional and local levels in the former Yugoslav Republic of Macedonia on the health risks associated with climate change and infectious diseases. This manual was devel-
oped as part of the WHO Regional Office for Europe project, Protecting health from climate change: a seven–country initiative, implemented with financial support from the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety.

Tuberculosis (TB) is an infectious disease that usually affects the lungs, though it can affect any organ in the body. It can develop when bacteria spread through droplets in the air. TB can be fatal, but in many cases, TB is preventable and treatable. This report examines the human rights impact of... the prevalence of Tuberculosis (TB) and Multi-drug-resistant tuberculosis (MDR-TB) among the Indigenous San peoples of Namibia. Combining political economy and root-cause methodology, the report explores the socioeconomic factors that make the San vulnerable to TB and limit their access to adequate health services.

The Committee discussed the implications for preparedness for smallpox-like events reflected by the ongoing COVID-19 pandemic. The Committee noted how quickly diagnostics and vaccines could be developed and deployed when resources and political will were abundant. This rapidity was also due to the f...act that the genetic sequence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had been shared worldwide. It was noted that in one country SARS-CoV-2 had been reconstructed in a laboratory from the viral genome sequence before the first case of COVID-19 had been reported, highlighting the benefits of synthetic biology technologies for accelerated development of diagnostics as well as the oft-described potential risks. Lessons learned about clinical care during the COVID-19 pandemic were also discussed.

In sub-Saharan Africa (SSA), urgent action is needed to curb a growing crisis in cancer incidence and mortality.
Without rapid interventions, data estimates show a major increase in cancer mo...rtality from 520 348 in 2020 to about
1 million deaths per year by 2030. Here, we detail the state of cancer in SSA, recommend key actions on the basis of
analysis, and highlight case studies and successful models that can be emulated, adapted, or improved across the
region to reduce the growing cancer crises. Recommended actions begin with the need to develop or update national
cancer control plans in each country. Plans must include childhood cancer plans, managing comorbidities such as
HIV and malnutrition, a reliable and predictable supply of medication, and the provision of psychosocial, supportive,
and palliative care. Plans should also engage traditional, complementary, and alternative medical practices employed
by more than 80% of SSA populations and pathways to reduce missed diagnoses and late referrals. More substantial
investment is needed in developing cancer registries and cancer diagnostics for core cancer tests.

Loss and damage is an urgent concern, driven by the increasingly harmful effects of climate change. Communities are experiencing new types and forms of climate impact, of higher frequency and intensity, which they are not equipped to handle. These impacts compel vulnerable communities to migrate to ...find alternative livelihoods and ways to survive. But migration generates grave socioeconomic consequences. Through case study analysis from 12 regions in Asia, Africa and the Pacific, this paper explores how climate change-induced migration is creating physical health, mental health and wellbeing issues — both for migrants and the families they leave behind. It then provides recommendations to policymakers on how to strengthen policy, planning and response frameworks to support communities manage health and wellbeing risks created by climate impacts.

Indian markets caused a stir across the country.1
According to the Centre for Science and the Environment (CSE), a respected New Delhi-based NGO, most honey brands
sold in India contained varying amounts of antibiotics. Their consumption over time could induce resistance to antibiotics,
putting p...eople at risk of treatment failure in case of severe infections.
For the study, 12 samples were picked in Delhi, all well-known brands, including one each from Australia and Switzerland.
Antibiotics found included Chloramphenicol and various broad-spectrum drugs such as Ciprofloxacin and Erythromycin.

Abstract: Chagas disease is caused by infection with the protozoan Trypanosoma cruzi, and although over 100 years have passed since the discovery of Chagas disease, it still presents an increasing problem for global public health. A plethora of information concerning the chronic phase of human Chaga...s disease, particularly the severe cardiac form, is available in the literature. However, information concerning events during the acute phase of the disease is scarce. In this review, we will discuss the current status of acute Chagas disease cases globally, the immunological findings related to the acute phase and their possible influence in disease outcome, and reactivation of Chagas disease in immunocompromised individuals, a key point for transplantation and HIV invection management.

This sourcebook aims to detail why health needs to be part of urban and territorial planning and how to make this happen. It brings together two vital elements we need to build habitable cities on a habitable planet: 1) Processes to guide the development of human settlements – in this document ref...erred to as “urban and territorial planning (UTP)”; and 2) concern for human health, well-being and health equity at all levels – from local to global, and from human to planetary health.
This sourcebook identifies a comprehensive selection of existing resources and tools to support the incorporation of health into UTP, including advocacy frameworks, entry points and guidance, as well as tools and illustrative case studies. It does not provide prescriptions for specific scenarios – these should be determined by context, people and available resources.

FIND and Standard Diagnostics (SD) have developed a lateral flow rapid diagnostic test (RDT) to screen for
T.b. gambiense HAT that is cheap and easy to use. The tests are packed individually and are stable at 40°C for
up to 25 months; they are performed on fresh blood obtained from a finger prick..., and no instrument or electricity is required. The RDT detects host antibodies to infection in populations that are at risk, or in suspect individuals. Positive cases are subjected to further confirmatory methods to identify HAT patients.

Human African trypanosomiasis (HAT) has been an alarming global public health issue. The disease affects mainly poor and marginalized people in low-resource settings and is caused by two subspecies of haemoflagellate parasite, Trypanosoma brucei and transmitted by tsetse flies. Progress made in HAT ...control during the past decade has prompted increasing global dialogue on its elimination and eradication. The disease is targeted by the World Health Organization (WHO) for elimination as a public health problem by 2020 and to terminate its transmission globally by 2030, along-side other Neglected Tropical Diseases (NTD). Several methods have been used to control tsetse flies and the disease transmitted by them. Old and new tools to control the disease are available with constraints.
Currently, there are no vaccines available. Efforts towards intervention to control the disease over the past decade have seen considerable progress and remarkable success with incidence dropping progressively, reversing the upward trend of reported cases. This gives credence in a real progress in its elimination. This study reviews various control measures, progress and a highlight of control issues, vector and parasite barriers that may have been hindering progress towards its elimination.

Cutaneous leishmaniasis (CL) is a neglected infectious endemic disease that is transmitted through the bite of a vector insect (sandfly) of the Lutzomyia genus,typical of rural geographical territories, and causes disfiguring skin ulcers and disabilities. It is estimated that CL affects between 600 ...000 and 1 000 000 people a year around the world, mainly in the America s, the Mediterranean basin, the Middle East and Central Asia. Eighteen of the 21 countries that make up the Latin American (LA) region are considered endemic areas for this neglected tropical disease. Colombia is one of the countries that reports the majority of global cases with 6161 in 2020 and has the second highest number of cases in the Americas, after Brazil.

Mycetoma is a chronic infectious disease of the subcutaneous tissue with a high morbidity. This disease has been reported from countries between 30°N and 15°S since 1840 but the exact burden of disease is not known. It is currently unknown what the incidence, prevalence and the number of reported ...cases per year per country is. In order to estimate what the global burden of mycetoma is, a meta-analysis was performed. In total 50 studies were included, which resulted in a total of 8763 mycetoma cases. Most cases were found in men between 11 and 40 years of age. The foot was most commonly affected.

Snakebite envenoming affects millions of people worldwide annually and is a significant source of mortality. Preventing and treating the problem is complex and requires collaboration among the fields of public health, medicine, ecology, and laboratory science. After being removed from the category A... neglected tropical disease (NTD) list in 2013, snakebite envenoming was reinstated in 2017 in response to antivenom shortages and advocacy from researchers and international NGOs. In 2019, the World Health Organization (WHO) set a target to halve the number of deaths and cases of snakebite envenoming by 2030.

Yaws is targeted for eradication by 2030, using a strategy based on mass drug administration (MDA) with azithromycin. New diagnostics are needed to aid eradication. Serology is currently the mainstay for yaws diagnosis; however, inaccuracies associated with current serological tests makes it difficu...lt to fully assess the need for and impact of eradication campaigns using these tools. Under the recommendation of the WHO Diagnostic Technical Advisory Group (DTAG) for Neglected Tropical Diseases(NTDs), a working group was assembled and tasked with agreeing on priority use cases for developing target product profiles (TPPs) for new diagnostics tools.

The chapter Fostering Health Systems’ Monitoring to Better Serve Older Populations is part of the publication series entitled Decade of Healthy Aging: Situation and Challenges. The publications are designed to favor the prioritization of effective actions at the local level as well as the monitori...ng of data and public health policies, and providing evidence-based information. Along with the objective of presenting the available updated knowledge about the situation of health and aging at the beginning of the Decade of Healthy Aging in the Americas, this publication gives information about health systems’ monitoring to better serve the needs of older adults and emphasizes the need for societies and health systems to better adapt to an aging population. It introduces the 360-tool as a guide to adapt health systems through monitoring tracers/indicators and highlighting the data and information that is readily available, disaggregated by age. This information can aid in decision-making and resource allocation to support older adults’ needs. Concerning the 360-tool development, a consensus has been reached on seven tracer indicators with high relevance to informing policy, and case studies in selected countries have assessed the feasibility of this approach. The list of indicators and the process related to the development of the tool are presented in this publication. The Decade of Healthy Aging 2021-2030 is a period to guide action towards the transformation of societies by fostering the inclusion of older people in every decision. This publication intends to contribute to this strategy and highlight the upcoming challenges and opportunities on healthy aging.
