COVID-19 Transmission Due to Delta Variant in New York City Public Schools From October to December 2021.

This cohort study assesses COVID-19 prevention measures against the Delta variant by measuring the secondary attack rate for cases in students, teachers, and staff of New York City public schools from October to December 2021 and analyzing the likely direction of transmission for secondary cases.

A population-based assessment of the health of homeless families in New York City, 2001-2003.

Objectives: We compared estimated population-based health outcomes for New York City (NYC) homeless families with NYC residents overall and in low-income neighborhoods.

Methods: We matched a NYC family shelter user registry to mortality, tuberculosis, HIV/AIDS, and blood lead test registries maintained by the NYC Department of Health and Mental Hygiene (2001-2003).

Results: Overall adult age-adjusted death rates were similar among the 3 populations.

Congenital tuberculosis and management of exposure in three neonatal intensive care units.

Congenital tuberculosis (TB) is uncommon, and diagnosis may be delayed. We report a case of congenital TB and the management of exposure in three different neonatal intensive care units. This case demonstrates the need for a high index of suspicion, active communication among maternal and neonatal medical providers, and timely provider reporting of maternal disease, and emphasizes the relatively greater risk of transmission to health care workers versus infants in this setting.

Factors associated with positive tuberculin skin test results among HIV-infected persons in Orel Oblast, Russia.

Background: The treatment of persons living with human immunodeficiency virus/acquired immune-deficiency syndrome (PLWHAs) for latent tuberculosis infection (LTBI) reduces tuberculosis (TB) morbidity. Despite a high TB burden and an expanding human immunodeficiency virus epidemic, Russia had limited data on the utility of the tuberculin skin test (TST) for LTBI diagnosis in PLWHAs.

Objective: To determine the prevalence and predictors of positive TSTs in PLWHAs in Orel Oblast.

Prevalence of tuberculin skin test positivity in clinical population in New York City.

The prevalence of latent tuberculosis infection (LTBI) in the various populations of New York City (NYC), a city with a high density of non-US-born persons, is unknown. We examined the prevalence of TST positivity in patients who received a tuberculin skin test (TST) between 1/2002 and 8/2004 at any of 10 NYC health department chest centers. A positive TST was defined as an induration reaction to tuberculin of ≥10 mm.
