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.

Interim Assessement Report
The EMA review was started by the Agency’s Committee for Medicinal Products for Human Use (CHMP) to support decision-making by health authorities. This first interim report includes information on seven experimental medicines intended for the treatment of people infecte...d with the Ebola virus:
BCX4430 (Biocryst);
Brincidofovir (Chimerix);
Favipiravir (Fujifilm Corporation/Toyama);
TKM-100802 (Tekmira);
AVI-7537 (Sarepta);
ZMapp (Leafbio Inc.);
Anti-Ebola F(ab’)2 (Fab’entech).
The amount of information available for the seven treatments is highly variable. For some compounds there is no data from use in human subjects available. A small number of treatments have been administered to patients in the current Ebola outbreak as compassionate use. Finally, there are also medicines included in this review that have already been studied in humans, albeit for the treatment of other viral diseases.

Infectious diseases cause over one billion human infections per year, with millions of deaths each year globally. Extensive health and financial burden is seen from both established and emerging infectious diseases. Infectious diseases also affect plants and animals, which may pose threats to agricu...lture and water supplies with additional impacts on human health. This Question and Answers, prepared by the World Health Organization (WHO) and Convention on Biological Diversity (CBD) Secretariat under their joint work programme on biodiversity and health, and launched of the occasion of the International Day for Biodiversity 2020, summarizes some of the interlinkages between biodiversity and infectious diseases.
WHO is continuously monitoring and responding to the COVID 19 outbreak. This Q&A will be updated as more is known about COVID-19, how it is affecting people worldwide, and the effectiveness of interventions against the disease.

Health system resilience is not an inevitable byproduct of any investment in health but must be intentionally programmed and developed with necessary input, investment and contextualization. This technical product aims to guide national, subnational, and global health actors to operationalize the co...ncept of health system resilience for advancement of universal health coverage, health security and ultimately better health for all. It supports the translation of relevant conceptual guidance and high-level recommendations into practical actions.
The specific objectives are to:
present a concise overview of the concept of health system resilience;
provide a roadmap outlining practical and foundational steps for building health system resilience to be adapted to different contexts;
share examples of actions and tools, including stakeholder roles, to support country application of the roadmap.
The target audience for this work is the various stakeholders involved in strengthening health systems and public health including management of emergencies (from prevention and preparedness to response and recovery) and other public health challenges in countries. This ranges from the donors, policy-makers and decision-makers at global, national and subnational levels to the implementing institutions and line managers of health system functions and services across the health system building blocks.

The arrival and rapid spread of the mosquito-borne viral disease Chikungunya across the Americas is one of the most significant public health developments of recent years, preceding and mirroring the subsequent spread of Zika. Globalization in trade and travel can lead to the importation of these vi...ruses, but climatic conditions strongly affect the efficiency of transmission in local settings. In order to direct preparedness for future outbreaks, it is necessary to anticipate global regions that could become suitable for Chikungunya transmission. Here, we present global correlative niche models for autochthonous Chikungunya transmission. These models were used as the basis for projections under the representative concentration pathway (RCP) 4.5 and 8.5 climate change scenarios. In a further step, hazard maps, which account for population densities, were produced. The baseline models successfully delineate current areas of active Chikungunya transmission. Projections under the RCP 4.5 and 8.5 scenarios suggest the likelihood of expansion of transmission-suitable areas in many parts of the world, including China, sub-Saharan Africa, South America, the United States and continental Europe. The models presented here can be used to inform public health preparedness planning in a highly interconnected world.

The 20th century was a period of unprecedented ecological change, with dramatic reductions in natural ecosystems and biodiversity and equally dramatic increases in people and domestic animals. Never before have so many animals been kept by so many people—and never before have so many opportunities... existed for pathogens to pass from wild and domestic animals through the biophysical environment to affect people causing zoonotic diseases or zoonoses. The result has been a worldwide increase in emerging zoonotic
diseases, outbreaks of epidemic zoonoses as well as a rise in foodborne zoonoses globally, and a troubling persistence of neglected zoonotic diseases in poor countries.

The risks of the use of nuclear, radiological, biological or chemical (NRBC) weapons are heterogeneous. Each risk has its own implications for developing and deploying any capacity to assist victims of an NRBC event and, in parallel, for the health and security of the people bringing this assistance.... At an international level, there are no plans for assisting the victims of an NRBC event which are both adequate and safe. Recognizing
the realities of the contexts associated with each risk throws up numerous challenges; such recognition is also a prerequisite for addressing these challenges. The realities that have to be considered relate to:
1. developing, acquiring, training for and planning an NRBC response capacity;
2. deploying a response capacity in an NRBC event;
3. the mandates and policies of international organizations pertaining to NRBC events. The challenges that will pose the greatest difficulty for a humanitarian organization are those for which the solutions are ‘non-buyable’ and which involve making extremely difficult decisions. Attempting to assist victims of an NRBC event without a reality-based approach might generate ineffective and unacceptably dangerous situations for those involved.

Recent forecasts by the Food and Agriculture Organization of the United Nations (FAO) have indicated a risk of locust invasion in West Africa from June 2020. From East Africa, some swarms could reach the eastern part of the Sahel and continue westwards from Chad to Mauritania.
Surveillance and co...ntrol teams will be mobilized across the region with a focus on Burkina Faso, Chad, Mali, Mauritania, and the Niger, and extended to Senegal. Countries such as Cameroon, the Gambia and Nigeria are also on watch in the event that desert locust spreads to these highly acute food-insecure countries. Since the region could be threatened in the coming months, FAO is strongly encouraging no regret investments in preparedness and anticipatory action to control swarms and safeguard livelihoods, given already high levels of acute food insecurity. Therefore, cost estimates for preparedness, anticipatory action and rapid response have been assessed.

Interim guidance, 6 October 2021
Direct detection of SARS-CoV-2 viral proteins (antigens) in nasal swabs and other respiratory secretions using lateral flow immunoassays (also known as rapid diagnostic tests, RDTs) offers a faster and less expensive method to test for SARS-CoV-2 than the reference ...method, nucleic acid amplification tests (NAATs). This interim guidance offers recommendations on the priority uses of antigen-detecting rapid diagnostic tests (Ag-RDTs) in specific populations and settings, including (i) for primary case detection in symptomatic individuals suspected to be infected and asymptomatic individuals at high risk of COVID-19, (ii) for contact tracing, (iii) during outbreak investigations and (iv) to monitor trends of disease incidence in communities. Ag-RDTs meeting minimum performance requirements can be used outside of clinical and laboratory settings, including in communities, by trained operators in accordance with instructions. The guidance additionally provides recommendations on implementation, product selection and storage.

Following a long recovery from the economic crisis (2007–2013), young people in the EU proved to be more vulnerable to the effects of the restrictions put in place to slow the spread of the COVID-19 pandemic. Young people were more likely than older groups to experience job loss, financial insecur...ity and mental health problems. They reported reduced life satisfaction and mental well-being associated with the stay-at-home requirements and school closures. While governments responded quickly to the pandemic, most efforts to mitigate the effects of restrictions were temporary measures aimed at preventing job loss and keeping young people in education. This report explores the effects of the pandemic on young people, particularly in terms of their employment, well-being and trust in institutions, and assesses the various policy measures introduced to alleviate these effects.

South Africa reported it fist case of COVID-19 on 5 March 2020. While the first cases were imported, local transmission has led to a rapid increase in the number of cases. As of 21 April 2020, more than 3,400 cases and 58 deaths had been confirmed. On 15 March, President Cyril Ramaphosa declared a n...ational state of disaster, and the government has since taken several measures to curb the spread of the virus, including closing borders, implementing strict social distancing measures and a 35-day nation-wide lockdown. These measures, along with the global economic shock caused by the pandemic, are expected to generate rising needs requiring an immediate and urgent response. Although South Africa is considered an upper-middle-income country, the amount of disparities—social, economic, and gender—make the country particularly vulnerable during this emergency.

Cascading risks from rising prices and supply disruptions, April 2022.
Global resource markets are still reeling from the impacts of Russia’s invasion of Ukraine; the two countries are major suppliers of energy, food and fertilizers. Supply disruption and the sudden imposition, in response to the... crisis, of unprecedented economic sanctions, trade restrictions and policy interventions have caused prices of commodities to skyrocket.
Before the conflict, demand for global resources already exceeded supply and drove up prices as economies rebounded after the COVID-19 pandemic. This gave rise to a global cost-of-living crisis, characterized by increasing levels of energy and food poverty. This situation is likely to become much worse as a consequence of the war in Ukraine, and poses a threat to human security, particularly among low-income and vulnerable populations.
