Manipulation of the Innate Immune Response by Varicella Zoster Virus.

Front Immunol 2020 24;11. Epub 2020 Jan 24.

Infectious Diseases and Immunology, Faculty of Medicine and Health, Charles Perkins Centre, University of Sydney, Sydney, NSW, Australia.

Varicella zoster virus (VZV) is the causative agent of chickenpox (varicella) and shingles (herpes zoster). VZV and other members of the herpesvirus family are distinguished by their ability to establish a latent infection, with the potential to reactivate and spread virus to other susceptible individuals. This lifelong relationship continually subjects VZV to the host immune system and as such VZV has evolved a plethora of strategies to evade and manipulate the immune response. Read More

New approaches to controlling an outbreak of chickenpox in a large immigration detention setting in England: the role of serological testing and mathematical modelling.

Epidemiol Infect 2020 Feb 10;148:e25. Epub 2020 Feb 10.

North West London Health Protection Team, Public Health England, London, UK.

Chickenpox is caused by varicella-zoster-virus (VZV) and is highly contagious. Immigration detention settings are a high-risk environment for primary VZV transmission, with large, rapidly-changing populations in close quarters, and higher susceptibility among non-UK-born individuals. During outbreaks, operational challenges occur in detention settings because of high-turnover and the potential need to implement population movement restriction for prolonged periods. Read More

Characterization and Comparison of Genetic Variation in Clinical Varicella-Zoster Virus Isolates Collected from Shanghai and Urumqi, China.

Jpn J Infect Dis 2020 May 31;73(3):226-230. Epub 2020 Jan 31.

Department of Dermatology, Tongren Hospital, Shanghai Jiao Tong University School of Medicine.

Varicella-zoster virus (VZV) is a ubiquitous human herpesvirus that causes chickenpox and zoster. Considering that VZV is a relatively and genetically stable virus, its global surveillance clades provide essential information for VZV evolution, immigration, and importation of different viral strains and recombination events. Eighty-eight VZV isolates from China (Shanghai and Urumqi) were genotyped using a scattered single-nucleotide polymorphism method in this prospective study. Read More

Is antibody titer useful to verify the immunization after VZV Vaccine in MS patients treated with Fingolimod? A case series.

Mult Scler Relat Disord 2020 May 20;40:101963. Epub 2020 Jan 20.

Multiple Sclerosis Center, Second Division of Neurology, Department of Advanced Medical and Surgical Sciences, University of Campania "Luigi Vanvitelli", Italy.

Background: Fingolimod (FTY720, Gilenya) is a second line therapy to treat relapsing MS not responding to first-line treatments and/or with a high disease activity (according to Italian Regulatory authorities). Before starting Fingolimod, patients' immunity to varicella zoster virus (VZV) needs to be assessed and seronegative patients vaccinated. To test susceptibility and response, IgG antibodies are tested after immunization. Read More

Spatiotemporal Epidemiology of Varicella in Chongqing, China, 2014-2018.

Int J Environ Res Public Health 2020 01 20;17(2). Epub 2020 Jan 20.

Department of Epidemiology and Health Statistics, School of Public Health and Management, Chongqing Medical University, Chongqing 400016, China.

Although immunization against varicella using vaccines has been proven to be significant and effective in the past decades, varicella remains a major public health concern for many developing countries. Varicella vaccination has not been introduced into routine immunization programs in China, and varicella outbreaks have continued to occur. Taking the city of Chongqing, which has a high prevalence of varicella, as an example, this study explored the spatiotemporal epidemiology of varicella. Read More
