Varicella Outbreak Surveillance in Schools in Sentinel Jurisdictions, 2012-2015.

Background: In 2007, a routine second dose of varicella vaccine was recommended in the United States for children aged 4 to 6 years to better control varicella-zoster virus circulation and outbreaks. Sentinel varicella outbreak surveillance was established to assess feasibility of surveillance and describe outbreaks that are occurring.

Methods: Through the Centers for Disease Control and Prevention Epidemiology Laboratory Capacity funding, health departments conducted active surveillance for varicella outbreaks in schools from 2012 to 2015.

Impact of the US Two-dose Varicella Vaccination Program on the Epidemiology of Varicella Outbreaks: Data from Nine States, 2005-2012.

Background: A routine 2-dose varicella vaccination program was adopted in 2007 in the US to help further decrease varicella disease and prevent varicella outbreaks. We describe trends and characteristics of varicella outbreaks reported to the Centers for Disease Control and Prevention (CDC) during 2005-2012 from 9 states.

Methods: Data on varicella outbreaks collected by 9 state health departments were submitted to CDC using the CDC outbreak reporting worksheet.

Two-dose varicella vaccine effectiveness and rash severity in outbreaks of varicella among public school students.

Background: Universal 2-dose varicella vaccination was recommended in 2006 to further reduce varicella disease burden. This study examined 2-dose varicella vaccine effectiveness (VE) and rash severity in the setting of school-associated varicella outbreaks.

Methods: A case control study was conducted from January 2010 to May 2011 in all West Virginia public schools.

Long-term efficacy of a program to prevent beryllium disease.

Background: In 2000, a manufacturer of beryllium materials and products introduced a comprehensive program to prevent beryllium sensitization and chronic beryllium disease (CBD). We assessed the program's efficacy in preventing sensitization 9 years after implementation.

Methods: Current and former workers hired since program implementation completed questionnaires and provided blood samples for the beryllium lymphocyte proliferation test (BeLPT).

Evaluation of a preventive program to reduce sensitization at a beryllium metal, oxide, and alloy production plant.

Objective: We evaluated a workplace preventive program's effectiveness, which emphasized skin and respiratory protection, workplace cleanliness, and beryllium migration control in lowering beryllium sensitization.

Methods: We compared sensitization prevalence and incidence rates for workers hired before and after the program using available cross sectional and longitudinal surveillance data.

Results: Sensitization prevalence was 8.

Efficacy of a program to prevent beryllium sensitization among new employees at a copper-beryllium alloy processing facility.

Objectives: In 2000, 7% of workers at a copper-beryllium facility were beryllium sensitized. Risk was associated with work near a wire annealing/pickling process. The facility then implemented a preventive program including particle migration control, respiratory and dermal protection, and process enclosure.

Prenatal marijuana exposure contributes to the prediction of marijuana use at age 14.

Aim: To evaluate the effects of prenatal marijuana exposure (PME) on the age of onset and frequency of marijuana use while controlling for identified confounds of early marijuana use among 14-year-olds.

Design: In this longitudinal cohort study, women were recruited in their fourth prenatal month. Women and children were followed throughout pregnancy and at multiple time-points into adolescence.
