Myths and Misconceptions: Varicella-Zoster Virus Exposure, Infection Risks, Complications, and Treatments.

Myths and Misconceptions: Varicella-Zoster Virus Exposure, Infection Risks, Complications, and Treatments. Clin Ther. 2019 Jul 17;: Authors: Newman AM, Jhaveri R Abstract Varicella zoster and herpes zoster are infections caused by the highly contagious varicella-zoster virus (VZV). Despite widespread availability of vaccines against VZV, as well as varicella vaccination rates>95%, VZV remains a public health concern because of several common myths and misconceptions. Because of the success of routine varicella vaccination programs, some people mistakenly believe that varicella and herpes zoster are now no longer a threat to public health. Another common misconception is that shingles is less infectious than varicella; however, clinical evidence indicates otherwise. Several knowledge gaps exist around VZV transmission and the availability and use of varicella zoster immune globulin (human) for postexposure prophylaxis against VZV. To help reduce the incidence of severe disease in high-risk individuals (eg, elderly people, pregnant women, unvaccinated persons, infants, and immunocompromised children and adults), this article addresses misbeliefs and broadens awareness of VZV exposure, infection risks, complications, and treatments.

We present a young female patient (36 years) admitted to Department of Ophthalmology due to visual loss on the left eye. Magnetic resonance imaging showed demyelinating lesions in frontal and parietal lobe, periventricularly, in mesencephalon and right cerebellar hemisphere, and left optic neuritis; magnetic resonance angiography was normal. The patient's history revealed renal dysfunction, hypothyroidism, and miscarriage in the 6th month of pregnancy due to eclampsia, and Fabry disease in family (mother and two sisters). She was transferred to the Department of Neurology for further evaluation of the demyelinating disorde...

AbstractHerpes zoster (shingles) is the reactivation of dormant varicella zoster virus in individuals who previously experienced varicella infection or vaccination. Herpes zoster can occur in pregnancy, although it is rare. This case report describes the clinical presentation and diagnosis of herpes zoster and reviews current recommendations for treatment. Preventative measures and the role of immunization are discussed in addition to clinical implications for intrapartum, postpartum, and newborn care to guide practitioners in caring for women experiencing or exposed to herpes zoster in pregnancy.

Authors: Hayward K, Cline A, Stephens A, Street L Abstract An infection with the varicella-zoster virus (VZV) causes both varicella and herpes zoster (HZ). Although rare, the development of HZ does occur during pregnancy. Maternal HZ does not result in increased foetal mortality, and the passage of VZV to the foetus rarely occurs. However, HZ does increase maternal morbidity. Upon infection with HZ, patients typically present with a viral prodrome preceding the appearance of the characteristic zoster rash. HZ is usually diagnosed clinically by the zoster rash, but can also be confirmed by a polymerase chain reactio...

View Original Article Here: How Long Does Shingles Last In The Elderly? Shingles is a viral infection that follows a varicella-zoster infection, although it can take decades for symptoms of the secondary disease to emerge. The condition presents as a painful and blistering rash, but it is not life-threatening. According to the Center for Disease Control, there are nearly one million cases in the United States each year, and almost half of those cases are in older adults over age 60. Some people only see one instance of the illness, while others have recurring symptoms, but 30 percent of Americans will develop shingles at s...

Publication date: Available online 31 March 2017 Source:Reproductive Toxicology Author(s): Lawrence Segal, Karen Thacker, Michel Fochesato, Giulia Giordano, Nathalie Garçon, Eric Destexhe The herpes zoster subunit vaccine (HZ/su) is an investigational vaccine for the prevention of shingles, a disease caused by the varicella zoster virus (VZV). It is composed of recombinant VZV glycoprotein E (gE) and AS01. We assessed the potential toxic effects of gE/AS01 and AS01 alone on female and male fertility, and on embryo-fetal, pre- and post-natal development in Sprague-Dawley rats. Females were immunized before pairing a...

(Reuters Health) - Too many U.S. adults are not getting vaccinated, putting themselves and others at risk, immunization experts say. According to the latest available data, about 44 percent of adults over age 19 had a flu shot; 20 percent had a TDAP vaccine, which protects against tetanus, diphtheria and pertussis; and 20 percent of 19-to-64-year-olds at risk of pneumonia had that vaccine (compared to 60 percent of those over 65). Just 27 percent of those over age 60 were vaccinated against herpes zoster, which cuts the risk of shingles in half, according to new guidelines from the Advisory Committee on Immunization P...

​I want to reawaken awareness of a disappearing but highly contagious infectious disease — varicella. Thanks to immunizations for the wild-type varicella virus and shingles, or herpes zoster, younger health care providers are less aware of the appearance and clinical presentations of this viral infection.Presentations of this viral disease have markedly declined and presentations are often atypical since the advent of immunizations for varicella in 1995. This DNA virus within the herpes virus family is generally a mild childhood disease but can wreak physical havoc in adults, especially pregnant women. Immunosuppre...

Primary varicella infection (chickenpox) is common in the UK with over three-quarters of parents reporting a history of chickenpox in their children by 5 years of age.1 Following primary infection, the varicella zoster virus (VZV) remains dormant in the dorsal root ganglia and reactivates in later life following a decline in cell-mediated immunity to cause herpes zoster or shingles (HZ). Although chickenpox is generally mild and self-limiting in healthy children, secondary bacterial infections, pneumonia and neurological complications can occur. The risk of severe chickenpox is higher in immunocompromised individuals,...

This study aimed to evaluate HIV-1 and HIV-2 prevalence among pregnant women and to describe the demographic and clinical profile of patients with HIV-2 infection from 2003-2013 at St Camille and General Lamizana Military Medical Centers. A retrospective investigation was conducted using 12,287 medical records from patients screened for HIV. To respond to the lack of data available regarding HIV-2 treatment and also to address the approach to clinical, biological as well as therapeutic monitoring, 62 HIV-2 infected patients' medical records were studied. Seroprevalence of 10.6 and 0.14% were obtained, respectively for HIV-...
