Abstract
IMPORTANCE Scalable programs for school-based SARS-CoV-2 testing and surveillance are needed to guide in-person learning practices and inform risk assessments in kindergarten through 12th grade settings. OBJECTIVES To characterize SARS-CoV-2 infections in staff and students in an urban public school setting and evaluate test-based strategies to support ongoing risk assessment and mitigation for kindergarten through 12th grade in-person learning. DESIGN, SETTING, AND PARTICIPANTS This pilot quality improvement program engaged 3 schools in Omaha, Nebraska, for weekly saliva polymerase chain reaction testing of staff and students participating in in-person learning over a 5-week period from November 9 to December 11, 2020. Wastewater, air, and surface samples were collected weekly and tested for SARS-CoV-2 RNA to evaluate surrogacy for case detection and interrogate transmission risk of in-building activities. MAIN OUTCOMES AND MEASURES SARS-CoV-2 detection in saliva and environmental samples and risk factors for SARS-CoV-2 infection. RESULTS A total of 2885 supervised, self-collected saliva samples were tested from 458 asymptomatic staff members (mean [SD] age, 42.9 [12.4] years; 303 women [66.2%]; 25 Black or African American [5.5%], 83 Hispanic [18.1%], 312 White [68.1%], and 35 other or not provided [7.6%]) and 315 students (mean age, 14.2 [0.7] years; 151 female students [48%]; 20 Black or African American [6.3%], 201 Hispanic [63.8%], 75 White [23.8%], and 19 other race or not provided [6.0%]). A total of 46 cases of SARS-CoV-2 (22 students and 24 staff members) were detected, representing an increase in cumulative case detection rates from 1.2% (12 of 1000) to 7.0% (70 of 1000) among students and from 2.1% (21 of 1000) to 5.3% (53 of 1000) among staff compared with conventional reporting mechanisms during the pilot period. SARS-CoV-2 RNA was detected in wastewater samples from all pilot schools as well as in air samples collected from 2 choir rooms. Sequencing of 21 viral genomes in saliva specimens demonstrated minimal clustering associated with 1 school. Geographical analysis of SARS-CoV-2 cases reported district-wide demonstrated higher community risk in zip codes proximal to the pilot schools. CONCLUSIONS AND RELEVANCE In this study of staff and students in 3 urban public schools in Omaha, Nebraska, weekly screening of asymptomatic staff and students by saliva polymerase chain reaction testing was associated with increased SARS-CoV-2 case detection, exceeding infection rates reported at the county level. Experiences differed among schools, and virus sequencing and geographical analyses suggested a dynamic interplay of school-based and community-derived transmission risk. Collectively, these findings provide insight into the performance and community value of test-based SARS-CoV-2 screening and surveillance strategies in the kindergarten through 12th grade educational setting.

Abstract
Familial juvenile nephronophthisis (NPH) is an autosomal recessive cystic disease of the kidney that leads to end-stage renal failure in adolescence. NPH is the most common genetic cause of end-stage renal disease in children. A gene locus for nephronophthisis (NPH1) has been mapped by linkage analysis to chromosome 2q13. We report here the construction of a complete YAC contig in the minimum genetic region for NPH1 by STS content mapping using clones of the CEPH YAC libraries. A physical map of maximum distances between 32 STS markers was constructed, thereby defining the order of a total of 27 STS markers. Since D2S340 and D2S121 have previously been identified as flanking markers to the NPH1 gene, the new contig defines on a physical map the NPH1 minimum genetic region to a 6.4-Mb interval. As a novel assignment, expressed genes, some of which may be candidates for the disease, were localized to the NPH1 region. In addition, the known interstitial telomeric repeat on chromosome 2 was physically mapped to this region. This contig assembly provides the basis for closer definition of the NPH1 critical region through identification of more narrow flanking markers and for the construction of a transcriptional map of the region towards isolation of the NPH1 gene.
