This practical guideline establishes definitions for “contact”, “contact person”, “contact tracing” and other associated concepts. It allows for improvement of contact tracing strategies and provides recommendations attempting to answer some, though not all, questions that arose during t...he 2019 coronavirus pandemic and other outbreaks. The use of this guideline begins once people have been diagnosed and the potential for transmission exists. It is not, however, intended to assist with case investigation. The guideline empowers health workers, governments, and public health officials with the tools to implement effective contact tracing strategies.

This paper reviews the effects of vertical responses to COVID-19 on health systems, services, and people’s access to and use of them in LMICs, where historic and ongoing under-investments heighten vulnerability to a multiplicity of health threats. We use the term ‘vertical response’ to describ...e decisions, measures and actions taken solely with the purpose of preventing and containing COVID-19, often without adequate consideration of how this affects the wider health system and pre-existing resource constraints.

Event-based surveillance (EBS) is defined as the organized collection, monitoring, assessment and interpretation of mainly unstructured ad hoc information regarding health events or risks, which may represent an acute risk to health. Both indicator-based and event-based surveillance components serve... the early warning and response (EWAR) function of the public health surveillance system. The Framework for Event-based Surveillance offers guidance to public health practitioners seeking to implement EBS at each administrative level in their countries.

he pandemic has produced an unprecedented economic and social crisis, and it could generate a food, humanitarian, and political crisis if urgent measures are not taken. The policy options for addressing the pandemic entail consolidating national plans and achieving intersectoral consensus. The respo...nse should be structured in three nonlinear and interrelated phases—control, reactivation, and rebuilding—involving the participation of technical actors representing not only the field of health but also other social and economic areas. Measures implemented to control the pandemic as well as measures for the reactivation and rebuilding phases will require increased public investment in health until the recommended parameters are achieved.

Advances have been made through expanded interventions delivered through five public health approaches: innovative and intensified disease management; preventive chemotherapy; vector ecology and management; veterinary public health services; and the provision of safe water, sanitation and hygiene. I...n 2015 alone nearly one billion people were treated for at least one disease and significant gains were achieved in relieving the symptoms and consequences of diseases for which effective tools are scarce; important reductions were achieved in the number of new cases of sleeping sickness, of visceral leishmaniasis in South-East Asia and also of Buruli ulcer.
The report also considers vector control strategies and discusses the importance of the draft WHO Global Vector Control Response 2017–2030.

WHO needs US$2.54 billion to provide life-saving assistance to millions of people around the world facing health emergencies. WHO’s Health Emergency Appeal is a consolidation of WHO’s priorities and financial requirements for 2023 to carry out health interventions in emergency and humanitarian r...esponses. The number of people in need of humanitarian relief has increased by almost a quarter compared to 2022, to a record 339 million. WHO is responding to an unprecedented number of intersecting health emergencies: climate change-related disasters such as flooding in Pakistan and food insecurity across the Sahel in the greater Horn of Africa; the war in Ukraine; and the health impact of conflict in Yemen, Afghanistan, Syria and north eastern Ethiopia – all of these emergencies overlapping with the health system disruptions caused by the COVID-19 pandemic and outbreaks of measles, cholera, and other killers. Contributions to the appeal can be fully flexible, flexible across a region, or flexible within a country appeal.

The results of the report clearly show that in 2020, a year dominated by the emergence of COVID-19 and its associated health and economic crises, governments around the world rose to the challenge. Sharp increases in government spending on health at all country income levels underpinned the rise in ...health spending to a new high of US $9 trillion (approximately 11% of global GDP). Government health spending generally increased and offset declines in out-of-pocket spending. Importantly, the rise in government health spending was part of a much broader fiscal response to the pandemic. In high income and upper-middle income countries social protection spending also increased sharply in as governments attempted to cushion populations from the economic impacts of COVID-19. In contrast to health and social protection, growth in education spending was relatively subdued. Countries face the further challenge of sustaining increased public spending on health and other social sectors in the face of deteriorating macroeconomic conditions and rising debt servicing. This also includes the challenge of sustaining external support for low income countries, which is essential for reducing ensuring poverty, ensuring access to health services and strengthening pandemic preparedness.

These guidelines form part of efforts to institutionalize the prevention and containment of antimicrobial resistance (AMR) in healthcare facilities in South Africa, as outlined in the Antimicrobial Resistance Strategic Framework and Implementation Plan. The focus of these guidelines is on two interr...elated aspects of prevention of healthcare associated infections (HAIs) and their spread; and the application of antimicrobial stewardship (AMS) practices at hospital level. They aim to serve as a practical, step-by-step or ‘how-to’ guide, addressing the infection prevention and AMS components of a robust response in a hospital. They draw on
evidence from various international guidance documents and standards for interventions that have been shown to be successful in infection
prevention and AMS programmes. These interventions have been customised to the South African hospital setting based on local
experiences in the public and private health sectors. This was done through a series of workshops and requests for comment involving
country-level experts.

For centuries, indigenous peoples around the world have used their traditional knowledge to prepare for, cope with and survive disasters. Their methods and practices originated within their communities and have been maintained and passed down over generations. Until recently, policy makers have larg...ely ignored this vast body of knowledge, in favor of ‘Western’ science and technologybased methods of disaster risk reduction and response. Today, however, many of these traditional practices are considered important and necessary contributions to the conservation of biodiversity and environmental sustainability. Yet at the same time, this knowledge is under constant threat of being eroded or lost, making these communities more vulnerable...

Leptospirosis is a zoonotic disease with epidemic potential, especially after a heavy rainfall,
caused by a bacterium called Leptospira. Leptospira interrogans is pathogenic to humans and
animals, with more than 200 serologic variants or serovars. Humans usually acquire
leptospirosis through dire...ct contact with the urine of infected animals or a urine-contaminated
environment. Human-to-human transmission occurs only very rarely. Leptospirosis may present
with a wide variety of clinical manifestations, from a mild illness that may progress to a serious
and sometimes fatal disease. Its symptoms may mimic many diseases, such as influenza,
dengue and other viral haemorrhagic diseases; making the correct diagnosis (clinical and
laboratory) at the onset of symptoms is important to prevent severe cases and save lives,
primarily in outbreak situations.

Since the release of the first volume in May 2020, the COVID-19 pandemic has continued to rage around the world. By mid-March, 2021, countries around the globe had reported over 123 million cases—a nearly five-fold increase since this report’s previous volume—and over 2.7 million deaths attrib...uted to the disease. And while new case loads are currently on the rise again, the global health community has already administered almost 400 million doses of vaccines, at last offering some signs of hope and progress.
Economic impacts threaten to undo decades of recent progress in poverty reduction, child nutrition and gender equality, and exacerbate efforts to support refugees, migrants, and other vulnerable communities. National and local governments—together with international and private-sector partners—must deploy vaccines as efficiently, safely and equitably as possible while still monitoring for new outbreaks and continuing policies to protect those who do not yet have immunity.
More than ever, the world needs reliable and trustworthy data and statistics to inform these important decisions. The United Nations and all member organizations of the Committee for the Coordination of Statistical Activities (CCSA) collect and make available a wealth of information for assessing the multifaceted impacts of the pandemic. This report updates some of the global and regional trends presented in Volume I and offers a snapshot of how COVID-19 continues to affect the world today across multiple domains.

Language influences the way we think, how we perceive reality, and how we behave. With respect to HIV, language can embody stigma and discrimination, which impacts access to testing, acquisition of HIV, and engagement with treatment. Language plays a role in supporting respect and empowerment of ind...ividuals, as communities shape how they are referred to and the labels they wish to use. Consideration and use of appropriate language can strengthen the global response to the HIV pandemic by diminishing stigma and discrimination and increasing support and understanding for individuals and communities living with HIV.

Viral hepatitis is defined as inflammation of the liver cells due to viral infection. The burden of liver disease in South Africa is mostly underestimated as viral hepatitis, in particular chronic infection, is a silent and neglected cause of morbidity and mortality. However, the burden of disease i...s likely substantial given the prevalence of chronic viral hepatitis. This burden is further compounded by the lack of screening and access to care and treatment as well as inadequate disease surveillance, human and financial resources.
The National Guidelines for the Management of Viral Hepatitis were developed, with the purpose to:
inform healthcare workers in the public and private sectors about the disease, its epidemiology in South Africa and current methods of diagnosis and therapy
strengthen the healthcare response to viral hepatitis
empower communicable diseases workers and stakeholders to make informed decisions regarding appropriate and cost effective interventions

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.
