Understanding prenatal household exposures to per- and polyfluorylalkyl substances using paired Biological and dust measurements with sociodemographic and housing variables.

Per- and poly-fluoroalkyl substances (PFAS) are chemicals of concern-they are ubiquitous, persistent, with known and suspected health impacts.

Process and Outcome Evaluation of the Centers for Disease Control and Prevention's Health Communications Campaign, United States, March-September 2022.

Objectives: The health communications campaign aims to increase the awareness of latent tuberculosis infection (LTBI) primarily among people born in the Philippines and Vietnam and other non-US-born groups (consumers) and the health care providers (providers) who serve them.
