We investigated a yearlong varicella zoster virus outbreak in a highly susceptible young adult population at a large university in India. Outbreaks of varicella infection among adults are not well described in the literature. Infection control measures and vaccination policy for this age group and setting are needed.

Simian varicella virus (SVV), the primate counterpart of varicella zoster virus, causes varicella (chickenpox), establishes latency in ganglia and reactivates to produce zoster. We previously demonstrated that a recombinant SVV expressing the enhanced green fluorescent protein (rSVV.eGFP) is slightly attenuated both in culture and infected monkeys. Herein, we generated two additional recombinant SVVs to visualize infected cells in vitro and in vivo One harbors eGFP fused to the N-terminus of open reading frame (ORF) 9 (rSVV...

BACKGROUND: Varicella zoster virus (VZV) reactivation spans the spectrum from uncomplicated segmental herpes zoster to life-threatening disseminated CNS infection. Moreover, in the absence of a small animal model for this human pathogen, studies of pathogenesis at the organismal level depend on analysis of human biosamples. Changes in cerebrospinal fluid (CSF) metabolites may reflect critical aspects of host responses and end-organ damage in neuroinfection and neuroinflammation. We therefore applied a targeted metabolomics screen of CSF to three clinically distinct forms of VZV reactivation and infectious and non-infectious disease controls in order to identify biomarkers for CNS involvement in VZV reactivation...

We report the first application of ultra-deep sequencing (UDS) to varicella-zoster virus (VZV) genotypic antiviral testing in a case of acyclovir-resistant VZV infection initially detected by Sanger sequencing within a deeply immunocompromised heart transplant recipient. As added-value compared to Sanger analysis, UDS revealed complex dynamics of viral population under antiviral pressure. Varicella-zoster virus (VZV) is a ubiquitous human herpesvirus affecting populations worldwide. VZV is commonly acquired in youth whose primary infection usually manifests as benign varicella (chickenpox)...

Infection caused by Varicella zoster virus (VZV) is a common etiology of acute peripheral facial palsy (APFP). We aimed to assess the clinical significance of detecting VZV DNA from the saliva of patients with APFP. Saliva collected from thirty-six patients with unilateral APFP at initial visit was analyzed to detect VZV DNA by polymerase chain reaction. The House-Brackmann (HB) scale was used to evaluate FP severity on admission day, at week 2, and at weeks 10-12 after start of treatment. Among the 28 patients without rash, VZV DNA was detected in 3 patients (10...

Varicella virus is a neurotropic virus that can reactivate later in life to cause zoster or shingles. Typically, it affects elderly, immunocompromised population. We report an unusual case of an immunocompetent young adult presenting with occipital headache and zoster rash, without preherpetic and postherpetic neuralgia, who was diagnosed with varicella meningitis on Polymerase chain reaction (PCR). He was treated with intravenous acyclovir and later discharged on famciclovir. Diagnosis of varicella meningitis is difficult in the absence of typical features of zoster rash and requires high index of suspicion...

BACKGROUND: Herpes zoster is an illness which is especially common amongst the elderly in the Netherlands and which can express itself in various ways. Besides affecting sensory nerves, which leads to postherpetic pain, the varicella zoster virus may also invade motor nerves. CASE DESCRIPTION: A 73-year-old female went to the surgeon with symptoms of a painful swelling in the left lower abdomen. She had experienced herpes zoster at the site of the swelling a few months earlier...

Immune dysfunction is a well-known phenomenon in end-stage liver disease (ESLD). The pretransplant period offers a unique window for primary care physicians to optimize the transplant's vaccine protection before antirejection medications are initiated. Live vaccinations are selected cautiously but the varicella-zoster virus (VZV) vaccine, Zostavax, is recommended for pretransplant candidates. This case highlights an ESLD patient who developed disseminated cutaneous VZV within 30 days of vaccination.

INTRODUCTION: Here we present a case of atraumatic splenic rupture secondary to varicella infection requiring emergency splenectomy. The presentation was as would be expected for epstein barr virus (EBV) related splenic injury, which is well documented in the literature. Dermatological findings however suggested varicella zoster, and viral serology subsequently confirmed the diagnosis.

Mood disorders are common mental illnesses. Among the factors associated with major depression are exposures to infectious diseases including hepatitis C, influenza, varicella-zoster, and herpes viruses. In this study, we sought to evaluate further associations between viral exposure and depression. From the US Center for Disease Control's National Health and Nutrition Examination Survey, we obtained data about depression status, antidepressant use, exposure to hepatitis A, hepatitis B, herpes simplex virus type 1, herpes simplex virus type 2, human immunodeficiency virus, and cytomegalovirus, and sociodemographic variables and evaluated associations between depression and viral exposure in adjusted multivariable models...

Bacterial, viral, and parasitic pathogens add significant morbidity and even mortality to pregnancy-with adverse effects extending to both the gravida and the newborn. Three herpesviruses deserve considerable attention given the effects of perinatal infection on obstetric outcomes, specifically maternal and neonatal morbidity. In the following review, we will provide a description of cytomegalovirus, herpes simplex virus, and varicella zoster virus. For each viral pathogen, we will describe the epidemiology, natural history, screening and diagnosis modalities, treatments, and implications for antepartum care...

OBJECTIVE: Serological testing guidelines for vaccine-preventable infectious diseases in pregnant women are heterogeneous. It is unclear how vaccination history influences health care workers' (HCWs) attitudes about testing. The aim of this study was to describe current practices in screening for rubella, hepatitis B, and varicella-zoster virus (VZV) in pregnant women in the province of Québec. METHODS: In 2015, an electronic survey was distributed to HCWs who followed the case of at least one pregnant woman in the previous year and who could be contacted by email by their professional association...

A 97-year-old woman presented with 4-day history of vesicular rash, initially at the feet but then spread up to the thighs bilaterally, abdomen and trunk. The initial differentials included bullous pemphigus and cellulitis by the emergency department. She was then managed as bullous pemphigus by the acute medical team and started on high-dose steroids, with no other differentials considered. When her care was taken over by the general medical team, varicella zoster virus (VZV) infection was suspected. After confirmation by the dermatology team regarding the clinical diagnosis and the positive VZV DNA swabs, she was started on acyclovir...

INTRODUCTION: Varicella zoster virus (VZV) causes chicken pox and herpes zoster and is a self-limiting disease in healthy children. Vaccination is recommended for children, adolescents, and adults. This study discusses a healthy pediatric patient with negative immunoglobulin (Ig) G VZV antibody (Ab) status after two doses of varicella vaccine and then subsequently re-immunized. Since measurement of serum IgG titers alone may not reflect vaccine protection, we further evaluated cell-mediated and humoral immune responses before and after re-immunization...
