Article Synopsis
- The study implemented a Test to Stay (TTS) strategy in 32 early care and education (ECE) facilities in Illinois to understand SARS-CoV-2 transmission and testing preferences among staff and children after COVID-19 exposure.
- During the testing period, 331 participants were exposed to COVID-19, with a low secondary attack rate of 4.2%, and no further transmission to additional cases occurred.
- The TTS strategy allowed for significant in-person attendance, saving about 1915 in-person days for children and staff and 1870 workdays for parents.
Project (VEZ), an intensified surveillance of pregnant women with symptoms of the Zika virus disease (ZVD) in Colombia, aimed to evaluate the relationship between symptoms of ZVD during pregnancy and adverse pregnancy, birth, and infant outcomes and early childhood neurodevelopmental outcomes. During May-November 2016, pregnant women in three Colombian cities who were reported with symptoms of ZVD to the national surveillance system, or with symptoms of ZVD visiting participating clinics, were enrolled in Project VEZ. Data from maternal and pediatric (up to two years of age) medical records were abstracted.

Data from two national population-based surveillance systems for symptomatic Zika virus disease (ZVD) and birth defects provided complementary information on the effect of the Zika virus outbreak on pregnancies and infant outcomes.
Methods: We collected national surveillance data regarding cases of pregnant women with ZVD that were reported during the period from June 2015 through July 2016.
Objective: To estimate the prevalence of microcephaly and central nervous system (CNS) defects during the Zika virus (ZIKV) epidemic in Colombia and proportion attributable to congenital ZIKV infection.
Study Design: Clinical and laboratory data for cases of microcephaly and/or CNS defects reported to national surveillance between 2015 and 2017 were reviewed and classified by a panel of clinical subject matter experts. Maternal and fetal/infant biologic specimens were tested for congenital infection and chromosomal abnormalities.
Purpose: This study compared two blood glucose (BG) point of care sampling methods to determine which is least painful yet accurate.
Design: The two-period, two-treatment crossover trial compared the traditional fingertip sampling method to a form of alternative site testing (AST), palm of the hand.
Methods: Subjects received both methods of BG sampling to compare comfort and accuracy.
