This article reviews the different types of poxvirus infections. Smallpox, although eradicated, must continue to be monitored because of the potential risk of accidental or voluntary (by bioterrorism) reintroduction. Monkeypox and cowpox viruses are considered to be emergent today ; their high risk of dissemination is due to the increase in international transport as well as trends for new animals as pets and the loss of vaccinal protection against smallpox. Molluscum contagiosum (molluscipoxvirus) causes mild infections, is particularly frequent in children ; in adults it is a marker of the risk of sexually transmitted infections and can, in cases with profuse lesions, reveal AIDS...

Intentional release of infectious agents and biological weapons to cause illness and death has the potential to greatly impact pregnant women and their fetuses. We review what is known about the maternal and fetal effects of seven biological threats: Bacillus anthracis (anthrax); variola virus (smallpox); Clostridium botulinum toxin (botulism); Burkholderia mallei (glanders) and Burkholderia pseudomallei (melioidosis); Yersinia pestis (plague); Francisella tularensis (tularemia); and Rickettsia prowazekii (typhus)...

Argument Revising the diffusionist view of current scholarship on the Pasteur Institutes in China, this paper demonstrates the ways in which local networks and circumstances informed the circulation and construction of knowledge and practices relating to smallpox prophylaxis in the Southwest of China during the early twentieth century. I argue that the Pasteur Institute of Chengdu did not operate in a natural continuity with the preceding local French medical institutions, but rather presented an intentional break from them...

In the event of a bioterror attack with variola virus (smallpox), exposure may only be identified following onset of fever. To determine if antiviral therapy with brincidofovir (BCV; CMX001) initiated at, or following, onset of fever could prevent severe illness and death, a lethal rabbitpox model was used. BCV is in advanced development as an antiviral for the treatment of smallpox under the US Food and Drug Administration's 'Animal Rule'. This pivotal study assessed the efficacy of immediate versus delayed treatment with BCV following onset of symptomatic disease in New Zealand White rabbits intradermally inoculated with a lethal rabbitpox virus (RPXV), strain Utrecht...

The smallpox vaccine based on the vaccinia virus was successfully used to eradicate smallpox, but although very effective, it was a very reactogenic vaccine and responsible for the deaths of one to two people per million vaccinated. Modified Vaccinia virus Ankara (MVA) is an attenuated derivative, also used in the smallpox eradication campaign and now being developed as a recombinant viral vector to produce vaccines against infectious diseases and cancer. MVA can encode one or more foreign antigens and thus can function as a multivalent vaccine...

REVIEW

Regulated cell death is a powerful anti-viral mechanism capable of aborting the virus replicative cycle and alerting neighbouring cells to the threat of infection. The biological importance of regulated cell death is illustrated by the rich repertoire of host signalling cascades causing cell death and by the multiple strategies exhibited by viruses to block death signal transduction and preserve cell viability. Vaccinia virus (VACV), a poxvirus and the vaccine used to eradicate smallpox, encodes multiple proteins that interfere with apoptotic, necroptotic and pyroptotic signalling...

John Lloyd, James Cheyne
International efforts to eradicate smallpox in the 1960s and 1970s provided the foundation for efforts to expand immunization programmes, including work to develop immunization supply chains. The need to create a reliable system to keep vaccines cold during the lengthy journey from the manufacturer to the point of use, even in remote areas, was a crucial concern during the early days of the Expanded Programme on Immunization. The vaccine cold chain was deliberately separated from other medical distribution systems to assure timely access to and control of vaccines and injection materials...

This paper uses techniques of binary logistic regression to identify the spatial determinants of the last national epidemic of smallpox to spread in England and Wales, the variola minor epidemic of 1921-34. Adjusting for age and county-level variations in vaccination coverage in infancy, the analysis identifies a dose-response gradient with increasing odds of elevated smallpox rates in local government areas with (i) medium (odds ratio [OR] = 5.32, 95% Confidence Interval [95% CI] 1.96-14.41) and high (OR = 11...

The immune system contributes to the maintenance of health by preventing and limiting the clinical consequences of infections by pathogenic microorganisms. During the evolution of Homo sapiens, those with the fittest immune system survived. The immune system of Homo sapiens was further improved and adapted by admixture with Neanderthal genes. Nowadays, the human immune system provides adequate protection against the majority of infections. For some 20 infectious diseases, the immune system needs to be improved by vaccination...

Monkeypox virus (MPXV) is a human pathogen that is a member of the Orthopoxvirus genus, which includes Vaccinia virus and Variola virus (the causative agent of smallpox). Human monkeypox is considered an emerging zoonotic infectious disease. To identify host factors required for MPXV infection, we performed a genome-wide insertional mutagenesis screen in human haploid cells. The screen revealed several candidate genes, including those involved in Golgi trafficking, glycosaminoglycan biosynthesis and glycosylphosphatidylinositol (GPI) - anchor biosynthesis...

Background.: Human infection by orthopoxviruses is being reported with increasing frequency, attributed in part to the cessation of smallpox vaccination and concomitant waning of population-level immunity. In July 2015, a female resident of interior Alaska, presented to an urgent care clinic with a dermal lesion consistent with poxvirus infection. Laboratory testing of a virus isolated from the lesion confirmed infection by an Orthopoxvirus. Methods.: The virus isolate was characterized by using electron microscopy and nucleic acid sequencing...

Multicriteria decision analysis (MCDA) is rightly receiving increasing attention in health technology assessment. Nevertheless, a distinguishing feature of the health domain is that technologies must actually improve health, and good performance on other criteria cannot compensate for failure to do so. We argue for two reasonable tests for MCDA models: the treacle test (can a winning intervention be incompletely ineffective?) and the smallpox test (can a winning intervention be for a disease that no one suffers from?)...

The eradication of smallpox and the elimination of several other infectious diseases from much of the world has provided convincing evidence that vaccines are among the most effective interventions for promoting health. The current scepticism about immunisation among members of the new US administration carries a risk of decreasing immunisation rates also in Europe. While only a small minority of the population are strongly anti-vaccine, their public activities have significantly influenced an uncertainty among the general population about both the safety of and the necessity for vaccination...

Vaccinia Virus (VACV) is an enveloped double stranded DNA virus and the active ingredient of the smallpox vaccine. The systematic administration of this vaccine led to the eradication of circulating smallpox (variola virus, VARV) from the human population. As a tribute to its success, global immunization was ended in the late 1970s. The efficacy of the vaccine is attributed to a robust production of protective antibodies against several envelope proteins of VACV, which cross-protect against infection with pathogenic VARV...

INTRODUCTION: To guide the use of modified vaccinia Ankara (MVA) vaccine in response to a release of smallpox virus, the immunogenicity and safety of shorter vaccination intervals, and administration by jet injector (JI), were compared to the standard schedule of administration on Days 1 and 29 by syringe and needle (S&N). METHODS: Healthy adults 18-40years of age were randomly assigned to receive MVA vaccine subcutaneously by S&N on Days 1 and 29 (standard), Days 1 and 15, or Days 1 and 22, or to receive the vaccine subcutaneously by JI on Days 1 and 29...

An Adverse Event Following Immunization (AEFI) is an adverse reaction to a vaccination that goes above and beyond the usual side effects associated with vaccinations. One serious AEFI related to the smallpox vaccine is myopericarditis. Metabolomics involves the study of the low molecular weight metabolite profile of cells, tissues, and biological fluids, and provides a functional readout of the phenotype. Metabolomics may help identify a particular metabolic signature in serum of subjects who are predisposed to developing AEFIs...
