Multilevel sociodemographic and socioeconomic disparities in COVID-19 outcomes in the Central Puget Sound region, 2020-2021
Presence of at least one underlying health condition (UHC) is positively associated with severe COVID-19. Although disparities in severe COVID-19 outcomes by race, ethnicity, and socioeconomic position (SEP) are extensively documented, there is little research examining these associations beyond the effect of UHCs. Studies also show regions of lower SEP and higher racial residential segregation…

In addition, the HIV/STI prevalence and behaviors of their sex…
New Insights into Neisseria gonorrhoeae (NG): Geographic heterogeneity in Black-White disparities and spatiotemporal trends among US females and the role of azithromycin use for STI treatment in antibiotic resistance
Gonorrhea (caused by the Neisseria gonorrhoeae (NG) bacterium) is the second most-commonly reported sexually transmitted infection (STI) in the United States (US) and can cause serious, permanent reproductive sequalae in females.
