ABSTRACT

The Global Virus Network (GVN) was established in 2011 to strengthen research and responses to emerging viral causes of human disease and to prepare against new viral pandemics. There are now 40 GVN Centers of Excellence and 6 Affiliate laboratories in 24 countries. The 2017 meeting was held from September 25-27 in Melbourne, Australia, and was hosted by the Peter Doherty Institute for Infection and Immunity and the Institut Pasteur. This report highlights the recent accomplishments of GVN researchers in several important areas of medical virology, including the recent Zika epidemic, infections by human papillomavirus, influenza, HIV, hepatitis C, HTLV-1, and chikungunya viruses, and new and emerging viruses in the Australasia region. Plans for the 2018 meeting also are noted.

ABSTRACT

The past five years have seen a revolution in the treatment of chronic hepatitis C, as short duration oral regimens of direct-acting antiviral drugs (DAAs), with nearly 100% cure rates for all genotypes, have replaced longer courses of ribavirin and injected interferon. Although initially very expensive, these DAAs are now becoming available in generic equivalents in countries with large numbers of chronically infected people, such as India. However, a number of obstacles may hinder the delivery of these drugs in resource-limited settings, including lack of access to diagnostic testing and the restriction of treatment to a small number of medical specialists. New approaches are therefore needed to make DAAs available to the estimated 71 million infected people, many of whom disproportionately live in low- or middle-income countries. A recent pilot study (ASCEND) of hepatitis C management in a low-income population in Washington, D.C., demonstrated that trained nurse practitioners, primary care physicians and hepatologists were equally successful in diagnosing and treating patients, indicating that such an approach might be successful in resource-limited regions of the world. Members of the Global Virus Network have received funding to carry out a similar training project in a region of India with a high prevalence of hepatitis C. This paper reviews the challenges of delivering DAA therapy in low- and middle-income countries, describes plans for performing and evaluating the effectiveness of a training program in India, and discusses future needs for the eventual elimination of hepatitis C.

ABSTRACT

In response to the outbreak of Zika virus (ZIKV) infection in the Western Hemisphere and the recognition of a causal association with fetal malformations, the Global Virus Network (GVN) assembled an international taskforce of virologists to promote basic research, recommend public health measures and encourage the rapid development of vaccines, antiviral therapies and new diagnostic tests. In this article, taskforce members and other experts review what has been learned about ZIKV-induced disease in humans, its modes of transmission and the cause and nature of associated congenital manifestations. After describing the make-up of the taskforce, we summarize the emergence of ZIKV in the Americas, Africa and Asia, its spread by mosquitoes, and current control measures. We then review the spectrum of primary ZIKV-induced disease in adults and children, sites of persistent infection and sexual transmission, then examine what has been learned about maternal-fetal transmission and the congenital Zika syndrome, including knowledge obtained from studies in laboratory animals. Subsequent sections focus on vaccine development, antiviral therapeutics and new diagnostic tests. After reviewing current understanding of the mechanisms of emergence of Zika virus, we consider the likely future of the pandemic.

ABSTRACT

The Global Virus Network (GVN) was established in 2011 in order to strengthen research and responses to current viral causes of human disease and to prepare against new viral pandemic threats. There are now 38 GVN Centers of Excellence and 6 Affiliate laboratories in 24 countries. GVN scientists meet annually to learn about each other's current research, address collaborative priorities and plan future programs. The 2016 meeting was held from October 23-25 in Hokkaido, Japan, in partnership with the Japanese Society for Virology, the National Institute of Infectious Diseases of Japan and the Research Center for Zoonosis Control of Hokkaido University. This report highlights the accomplishments of GVN researchers in many priority areas of medical virology, including the current Zika epidemic, infections by human papillomavirus, influenza, Ebola, Lassa, dengue, HIV, hepatitis C, and chikungunya viruses, and the development of improved diagnostics and new vaccines.

ABSTRACT

The recent spread of chikungunya virus to the Western Hemisphere, together with the ongoing Ebola epidemic in West Africa, have highlighted the importance of international collaboration in the detection and management of disease outbreaks. In response to this need, the Global Virus Network (GVN) was formed in 2011. The GVN is a coalition of leading medical virologists in 34 affiliated laboratories in 24 countries, who collaborate to share their resources and expertise. The GVN supports research, promotes training for young scientists, serves as a technical resource for governments, businesses and international organizations, facilitates international scientific cooperation, and advocates for funding and evidence-based public policies. In response to the spread of chikungunya, the GVN formed a task force to identify research gaps and opportunities, including models of infection and disease, candidate vaccines and antivirals, epidemiology and vector control measures. Its members also serve as authoritative sources of information for the public, press, and policy-makers. This article forms part of a symposium in Antiviral Research on "Chikungunya discovers the New World".

ABSTRACT

BACKGROUND: Some patients with medically unexplained symptoms or alternative medical diagnoses suspect that they chronically suffer from the tick-borne infection Lyme disease. These patients are commonly targeted by providers of alternative therapies. This study was designed to identify and characterize the range of unorthodox alternative therapies advertised to patients with a diagnosis of Lyme disease. METHODS: Internet searches using the Google search engine were performed to identify the websites of clinics and services that marketed nonantimicrobial therapies for Lyme disease. We subsequently used the PubMed search engine to identify any scientific studies evaluating such treatments for Lyme disease. Websites were included in our review so long as they advertised a commercial, nonantimicrobial product or service that specifically mentioned utility for Lyme disease. Websites with patient testimonials (such as discussion groups) were excluded unless the testimonial appeared as marketing on a commercial site. RESULTS: More than 30 alternative treatments were identified, which fell into several broad categories: these included oxygen and reactive oxygen therapy; energy and radiation-based therapies; nutritional therapy; chelation and heavy metal therapy; and biological and pharmacological therapies ranging from certain medications without recognized therapeutic effects on Borrelia burgdorgeri to stem cell transplantation. Review of the medical literature did not substantiate efficacy or, in most cases, any rationale for the advertised treatments. CONCLUSIONS: Providers of alternative therapies commonly target patients who believe they have Lyme disease. The efficacy of these unconventional treatments for Lyme disease is not supported by scientific evidence, and in many cases they are potentially harmful.

ABSTRACT

Advocacy for Lyme disease has become an increasingly important part of an antiscience movement that denies both the viral cause of AIDS and the benefits of vaccines and that supports unproven (sometimes dangerous) alternative medical treatments. Some activists portray Lyme disease, a geographically limited tick-borne infection, as a disease that is insidious, ubiquitous, difficult to diagnose, and almost incurable; they also propose that the disease causes mainly non-specific symptoms that can be treated only with long-term antibiotics and other unorthodox and unvalidated treatments. Similar to other antiscience groups, these advocates have created a pseudoscientific and alternative selection of practitioners, research, and publications and have coordinated public protests, accused opponents of both corruption and conspiracy, and spurred legislative efforts to subvert evidence-based medicine and peer-reviewed science. The relations and actions of some activists, medical practitioners, and commercial bodies involved in Lyme disease advocacy pose a threat to public health.

ABSTRACT

Johnson and Stricker published an opinion piece in the Journal of Medical Ethics presenting their perspective on the 2008 agreement between the Infectious Diseases Society of America (IDSA) and the Connecticut Attorney General with regard to the 2006 IDSA treatment guideline for Lyme disease. Their writings indicate that these authors hold unconventional views of a relatively common tick-transmitted bacterial infection caused by the spirochete Borrelia burgdorferi. Therefore, it should come as no surprise that their opinions would clash with the IDSA's evidence-based guidelines for the diagnosis and treatment of Lyme disease. Their allegations of conflict of interest against the IDSA resemble those made against the National Institutes of Health, the Food and Drug Administration and the Centers for Disease Control and Prevention in 2000, which were found to be baseless. It is the responsibility of all physicians and medical scientists to stand up to antiscientific, baseless and unethical attacks on those who support an evidence-based approach to caring for patients.

ABSTRACT

In 2001, spores of Bacillus anthracis were deliberately sent through the United States postal system, resulting in five deaths from inhalational anthrax. Rarely observed clinical symptoms associated with these cases led to a hypothesis about the etiology of the English Sweating Sickness. The disease appeared sporadically in England between 1485 and 1551. Numerous viruses have been proposed as possible causes of the "English Sweat". Anthrax has not previously been considered because, documented cases of inhalational anthrax have been rare and pronounced sweating was not a noted symptom of the more common cutaneous and gastrointestinal forms of anthrax. Victims of the English Sweating Sickness have recently been identified in undisturbed tombs. It may be possible to examine those bodies and coffins for the presence of resilient anthrax spores and DNA using modern genomic tools.
