MMWR News Synopsis for March 19, 2015

Tuberculosis Trends - United States, 2014

New national TB surveillance data reaffirm that TB control is working in the United States. Together, CDC and its public health partners are steadily navigating the nation towards the elimination of TB. Preliminary data from CDC’s National TB Surveillance System reveal a continued drop in tuberculosis cases and rates with a total of 9,412 cases reported in 2014 and a 2.2 percent decline in the rate from 2013 (to 3.0 cases per 100,000 population). Yet, data suggest progress is slowing, with 2013-14 experiencing the smallest decline in TB rates in over a decade. TB also continues to strike a heavier blow in certain communities and vulnerable populations.
HIV Infection and HIV-Associated Behaviors Among Persons Who Inject Drugs — 20 Cities, United States, 2012

While HIV prevalence and risk behaviors among persons who inject drugs (PWID) have remained stable in recent years, and positive increases have occurred in behavioral intervention participation and hepatitis C (HCV) testing, risk remains high among this population. The National HIV Behavioral Surveillance (NHBS) system analyzes trends in HIV testing, risk behavior, and use of prevention services among PWID; in 2012, 10,002 PWID in 20 large U.S. cities participated. In comparison to 2009, data showed no significant changes in HIV prevalence, awareness of infection, reported risk behavior, or HIV testing. Eleven percent were infected with HIV, and 63 percent of those were aware of their infection.  

Healthful Food Availability in Stores and Restaurants - American Samoa, 2014

Rapid assessment of the retail food environment can generate data to support strategies to improve availability, affordability, and promotion of healthful foods. American Samoa (AS) has the highest recorded prevalence of adults with obesity (75%) worldwide. It is suspected that the nutritionally poor food and beverage options of food retail venues in AS communities are a contributing factor. A rapid assessment of the retail food environment was conducted using Nutrition Environment Measures Surveys in 9 grocery, 61 convenience stores, and 20 restaurants. In convenience stores, healthful items were not as available as less healthful counterparts, and some healthful items were more expensive than their less healthful counterparts.
