Changes in HIV Preexposure Prophylaxis (PrEP) Awareness and Use Among Men Who Have Sex with Men — 20 Urban Areas, 2014 and 2017

CDC Media Relations

Use of a daily pill for HIV prevention – HIV preexposure prophylaxis or PrEP – has increased but remains too low, particularly among gay and bisexual African American and Latino men. More gay and bisexual men at high risk for HIV are using PrEP. CDC analyzed data from more than 7,800 interviews with gay and bisexual men at high risk for HIV in 20 U.S. cities. The analysis found that reported PrEP use increased from 6% to 35% — and that reported awareness of PrEP increased from 60% to 90% — among the survey participants between 2014 and 2019. Despite those increases, PrEP use remains too low. African American and Latino gay and bisexual men reported lower PrEP awareness and use than white gay and bisexual men. To end the HIV epidemic in the United States, healthcare providers should routinely test their patients for HIV, assess HIV-negative patients for indications of HIV risk, and appropriately prescribe PrEP.

Workplace Secondhand Tobacco Smoke Exposure among U.S. Nonsmoking Workers —National Health Interview Survey, 2015

CDC Media Relations

Although cigarette smoking has declined among U.S. workers, almost 20% of non-smoking workers reported exposure to secondhand tobacco smoke (SHS) at work, and 10% reported frequent exposure (twice a week or more). Non-smoking workers living in states without comprehensive smoke-free laws and workers in certain industries were more likely to report exposure to workplace SHS. The industries with the highest prevalence of SHS exposure and the highest number of exposed workers include outdoor workplaces and other settings that are unlikely to be protected by smoke-free laws. NIOSH encourages employers to implement workplace-specific smoke-free policies to complement state and local smoke-free laws.
