In 2019, a new human pandemic coronavirus (SARS-CoV-2) has emerged in Wuhan, China. We present the actual state of knowledge on Betacoronaviruses, including data on SARS-CoV-2, SARS-CoV and MERS-CoV. Betacoronaviruses are enveloped viruses with nonsegmented, positive-sense single-stranded RNA genome. SARS-CoV, MERSCoV, and SARS-CoV-2 are highly pathogenic zoonotic viruses. SARS-CoV-2 is an etiological factor of COVID-19, which has been brought to global attention and declared a pandemic by the World Health Organization in 2020. The SARS-CoV-2 is similar to other coronaviruses, nevertheless some differences were observed. As no specific therapeutics and vaccines are available for disease control, the epidemic of COVID-19 is posing a great threat for the global public health.

In March 2020, the World Health Organization (1) declared COVID-19 as a pandemic and a threat to global public health (2). The virus mainly affects the lungs and can cause acute respiratory distress syndrome (ARDS). In addition, coronavirus 2 severe acute respiratory syndrome (SARSCOV2) also has devastating effects on other important organs, including the circulatory system, brain, gastrointestinal tract, kidneys and liver

ArgumentScientific uncertainty is fundamental to the management of contemporary global risks. In 2009, the World Health Organization (WHO) declared the start of the H1N1 Influenza Pandemic. This declaration signified the risk posed by the spread of the H1N1 virus, and in turn precipitated a range of actions by global public health actors. This article analyzes the WHO's public representation of risk and examines the centrality of scientific uncertainty in the case of H1N1. It argues that the WHO's risk narrative reflected the context of scientific uncertainty in which it was working. The WHO argued that it was attempting to remain faithful to the scientific evidence, and the uncertain nature of the threat. However, as a result, the WHO's public risk narrative was neither consistent nor socially robust, leading to the eventual contestation of the WHO's position by other global public health actors, most notably the Council of Europe. This illustrates both the significance of scientific uncertainty in the investigation of risk, and the difficulty for risk managing institutions in effectively acting in the face of this uncertainty.

In the past 100 years, the world has faced four distinctly different pandemics: the Spanish flu of 1918-1919, the SARS pandemic of 2003, the H1N1 or “swine flu” pandemic of 2012, and the ongoing COVID-19 pandemic. Each public health crisis exposed specific systemic shortfalls and provided public health lessons for future events. The Spanish flu revealed a nursing shortage and led to a great appreciation of nursing as a profession. SARS showed the importance of having frontline clinicians be able to work with regulators and those producing guidelines. H1N1 raised questions about the nature of a global organization such as the World Health Organization in terms of the benefits and potential disadvantages of leading the fight against a long-term global public health threat. In the era of COVID-19, it seems apparent that we are learning about both the blessing and curse of social media.

Participation in the World Health Organization (WHO) is a multifaceted matter and should be understood as not only referring to the governance of WHO, but also to its scientific and technical work as well as its collaborative efforts towards advancing global public health more generally. The article is concerned, in particular, with the legal and political framework surrounding attendance and participation of states and various entities in the governing bodies of the Organization, at the global and regional level. It shows that participation in the governance of WHO is still today a domain reserved to the determination of its Member States. At the same time, solutions have been found and continued efforts are necessary to take into account geopolitical considerations and to ensure a meaningful and inclusive participation of all relevant actors in global health discussions.

Background: In 2020, the World Health Organization (WHO) released global guidelines on physical activity (PA) and sedentary behavior, for the first time providing population-based recommendations for people living with selected chronic conditions. This article briefly presents the guidelines, related processes and evidence, and, importantly, considers how they may be used to support research, practice, and policy. Methods: A brief overview of the scope, agreed methods, selected chronic conditions (adults living with cancer, hypertension, type 2 diabetes, and human immunodeficiency virus), and appraisal of systematic review evidence on PA/sedentary behavior is provided. Methods were consistent with World Health Organization protocols for developing guidelines. Results: Moderate to high certainty evidence (varying by chronic condition and outcome examined) supported that PA can reduce the risk of disease progression or premature mortality and improve physical function and quality of life in adults living with chronic conditions. Direct evidence on sedentary behavior was lacking; however, evidence extrapolated from adult populations was considered applicable, safe, and likely beneficial (low certainty due to indirectness). Conclusions: Clinical and public health professionals and policy makers should promote the World Health Organization 2020 global guidelines and develop and implement services and programs to increase PA and limit sedentary behavior in adults living with chronic conditions.

The Zika virus (ZIKV), first discovered in 1947, has emerged as a global public health threat over the last decade, with an accelerated geographic spread of the virus occurring in the last 5 years. The World Health Organization (WHO) predicts that millions of cases of ZIKV are likely to occur in the Americas between 2016 and 2017. These projections, in conjunction with an increase in newborn microcephaly cases that are suspected to be ZIKV-associated, prompted the WHO to declare a public health emergency of international concern in February 2016. With the current media attention, it is likely that GPs will be consulted on th topic, particularly by pregnant women.

Coronavirus disease - 2019 (COVID-19), caused by the SARS-CoV-2, is currently a major concern worldwide1. COVID-19 has produced millions of infections worldwide, also causing hundreds of thousands of deaths1, a fact that has led the World Health Organization (WHO) to declare COVID-19 as a pandemic2. This Letter aims to discuss the main characteristics of COVID-19 and to raise the need for a multidimensional and multidisciplinary approach to deal with this type of threat to global public health.

Abstract The World Health Organization designated the decade 2020–2030 as the “decade of healthy ageing.” It is a tragic irony that the year 2020 should begin with a pandemic that is so lethal for older persons. Not only are older persons the most vulnerable to COVID-19 mortality, but many of the mitigation efforts to slow the spread of the virus have imposed yet further emotional and mental health burdens on the most vulnerable among those older than 70 years. To help prevent future infectious disease mortality and suffering, as well as the profound health burdens from the chronic diseases associated with ageing, insights from biogerontology must become an integral part of global public health priorities. The timing is ripe for making the public health aspiration of developing an applied gerontological intervention a reality.
