SARS-CoV-2 antibody testing allows quantitative determination of disease prevalence, especially important in high-risk communities. We performed anonymized convenience sampling of 200 currently asymptomatic residents of Chelsea, the epicenter of COVID-19 illness in Massachusetts by BioMedomics SARS-CoV-2 combined IgM-IgG point-of-care lateral flow immunoassay. The seroprevalence was 31.5% (17.5% IgM+IgG+, 9.0% IgM+IgG- and 5.0% IgM-IgG+). 50.5% of participants reported no symptoms in the preceding 4 weeks, of which 24.8% (25/101) were seropositive, and 60% of these were IgM+IgG-. These data are the highest seroprevalence rates observed to date and highlight the significant burden of asymptomatic infection.

Background: Teleophthalmology is an evidence-based method for diabetic eye screening. It is unclear whether the type of eye care provider performing teleophthalmology interpretation produces significant variability. Introduction: We assessed grading variability between an optometrist, general ophthalmologist, and retinal specialist using images from an urban, diabetic retinopathy teleophthalmology program. Methods: Three readers evaluated digital retinal images in 100 cases (178 eyes from 90 patients with type 2 diabetes). Fisher's exact test, percent agreement, and the observed proportion of positive (P pos ) or negative agreement (P neg ) were used to assess variability. Results: Among cases deemed gradable by all three readers (n = 65), there was substantial agreement on absence of any reti-

Following a court decision (Rosie D. v. Romney), the Medicaid program in Massachusetts launched the statewide Children's Behavioral Health Initiative in 2008 to increase the recognition and treatment of behavioral health problems in pediatrics. We reviewed billing data (n = 64,194) and electronic medical records (n = 600) for well child visits in pediatrics in 2 practices to examine rates of behavioral health screening, problem identification, and treatment among children seen during the year before and 2 years after the program's implementation. According to electronic medical records, the percentage of well child visits that included any form of behavioral health assessment increased significantly during the first 2 years of the program, and pediatricians significantly increased their use of standardized screens. According to billing data, behavioral health treatment increased significantly. These findings suggest that behavioral health screening and treatment have increased following the Rosie D. decision.
