Objective. To evaluate the correlation between self-report of a prior history of chickenpox and results of varicella-zoster virus (VZV) immunoglobulin (Ig) G serologic test results in an outbreak of VZV infection among Thai healthcare workers (HCWs) and to conduct a cost-benefit analysis of establishing routine VZV immunization as part of an occupational health program on the basis of the outbreak data. Methods. All exposed patients received prophylaxis and the HCWs in our 3 intensive care… Expand
Varicella zoster virus infection among healthcare workers in Taiwan: seroprevalence and predictive value of history of varicella infection.
TLDR
A positive recall history of varicella infection and vaccination did not ensure the presence of protective VZV IgG, and a negative history was not predictive of a lack of immunity. Expand
Implementation of Hospital Policy for Healthcare Workers and Patients Exposed to Varicella-Zoster Virus
TLDR
The general information and healthcare-associated transmission of VZV is reviewed and the recommendations for the pre- and post-exposure management of HCWs and patients, in hospital settings are summarized. Expand
Varicella-zoster virus seroprevalence in healthcare workers in Kuala Lumpur, Malaysia.
TLDR
VZV screening of HCWs without a history of chickenpox, and vaccination of susceptible HCWs should be undertaken in this hospital. Expand
Prevalence and Characteristics of Pediatric Healthcare Workers without Immunity to Varicella zoster Virus.
TLDR
Implementing a strategy that involves testing of only those with an unknown VZV status and vaccination for only those determined to be non-immune costs 1,801 United States dollar (USD), less than the total cost (4,601 USD) for vaccinating all HCWs with uncertain status. Expand
Impact of varicella vaccine on nosocomial outbreaks and management of post exposure prophylaxis following in a paediatric hospital
TLDR
The number of annualvaricella hospital outbreaks at the HNRG decreased significantly after varicella vaccine was introduced to NIP in Argentina with a relevant reduction in terms of costs. Expand
Varicella Seroprevalence in Healthcare Workers at a Medical Center Following Changes in National and Local Hospital Vaccination Policies
TLDR
A small number of healthcare workers were inadequately protected, and antibody titers were lower than required to maintain herd immunity, and VZV IgG status should be documented for all HCWs, and susceptible HCWs should be vaccinated to avoid outbreaks. Expand
Screening and Vaccination Against Measles and Varicella Among Health Care Workers: A Cost-effectiveness Analysis
TLDR
Considering the progressive decline in antibody concentrations and the false-positive responses in self-reported histories, case 3, which involved administering 2-dose vaccinations to susceptible HCWs demonstrated by antibody screening tests for both measles and varicella, was the most cost-effective strategy. Expand
Seroepidemiology of Varicella and value of self-reported history of Varicella infection in Iranian medical students
TLDR
The relationships between marital status, number of family members, and acquired VZV history with immunity against the virus were statistically significant and students of Iranian medical sciences should be tested for Varicella immunity regardless of the history of previous infection. Expand
Is There any Seasonal Influence of Herpes Zoster
TLDR
A large-scale and prospective community based study is recommended to enrich the findings as well as a complete clinical and epidemiological picture of Herpes zoster in Bangladesh. Expand
Seroprevalence of measles, mumps, rubella, and varicella zoster virus antibodies among healthcare students: analysis of vaccine efficacy and cost-effectiveness
TLDR
In this study, participants’ immunity to measles and VZV was low, and prevaccination serological screening was cost-effectiveness method for preventing measles, mumps, rubella, and varicella infections. Expand

Varicella zoster virus immunity in multinational health care workers of a Saudi Arabian hospital.
TLDR
Overall, total varicella immunity of a multinational workforce can be realized through screening of HCWs and vaccination of susceptible individuals and serologic immunity to VZV infection proved consistent among the different nationalities and among the 4 occupational groups. Expand
A Cluster of Primary Varicella Cases Among Healthcare Workers With False-Positive Varicella Zoster Virus Titers
TLDR
LA may be prone to false- positive results and inappropriate for screening hospital HCWs and recommendations for avoiding false-positive serologic tests are provided. Expand
Susceptibility of hospital-based health care personnel to varicella-zoster virus infections.
TLDR
Screening strategies for VZV immunity in hospital employees could be made more efficient by performing serologic tests only on those persons aged 35 years or younger with a negative or uncertain history of the disease. Expand
High rate of varicella complications among Mexican-born adults in Alabama.
TLDR
Varicella is a more serious disease among adults than among children, and Mexican-born adults living in the United States might have a higher risk of acquiring varicella than US- born adults. Expand
Screening Healthcare Workers for Varicella-Zoster Virus: Can We Trust the History?
TLDR
The varicella-zoster virus seroprevalence among new employees was low, posing an important risk to existing employees and patients, and positive or negative history of chickenpox was an unreliable indicator of susceptibility among healthcare workers of different nationalities. Expand
Should health care workers in the tropics be immunized against varicella?
TLDR
Systematic selective vaccination of susceptible healthcare workers is recommended to break this cycle of annual varicella outbreaks among hospital personnel. Expand
Susceptibility to varicella-zoster virus in Thai children and young adults.
TLDR
The findings suggest that the IAHA and VZ skin test should be used together for assessing VZ immunity in immunocompromised children and young adults. Expand
Seroprevalence of varicella antibodies among new house officers.
TLDR
Although most house officers had protective titers, a reported history of varicella or the administration ofvaricella vaccine did not assure the presence of protective titer levels, and house officers should be tested for varICElla immunity regardless of a history of previous infection or the Administration of variceslla vaccine.

Review of varicella zoster seroepidemiology in India and South‐east Asia
TLDR
Age-related VZV seroprevalence patterns are described in Singapore Malaysia Philippines Thailand and India suggesting that temperate climates may favor the transmission of the varicella virus with incidence peaking during cooler months and in cooler more temperate regions. Expand
Reliability of a history of previous varicella infection in adults.
TLDR
A history of previous varicella infection in adults withvaricella may not be reliable and true second episodes of variceella are probably rare in immunocompetent adults. Expand
