Scientists Examine HIV's Effect On Immune System
A study by researchers from Duke University and the University of North Carolina-Chapel Hill and published in PLoS Medicine has found that upon infection "three lines of attack by the immune system are quickly neutralized by HIV," findings they hope "will provide a better understanding of how to develop a vaccine to protect against the virus," the Raleigh News & Observer reports. The study, lead by Duke"s Barton Haynes, showed that HIV, "once considered a slow if stealthy invader, actually works incredibly fast at disarming key immune fighters in the body." Haynes said scientists still have a difficult task in developing a vaccine, adding, "It would have to be different than any other vaccine made" (Avery, 7/7).

CDC Report Examines Sexual Health, AIDS Rates Among U.S. Teenagers, Young Adults

CDC"s latest Morbidity and Mortality Weekly Report (MMWR) examines the sexual health of young adults and teenagers in the U.S., Reuters reports. "The data presented in this report indicate that many young persons in the United States engage in sexual risk behavior and experience negative reproductive health outcomes," the MMWR states (7/16). For the report, CDC compiled data from several different studies involving hundreds of thousands of teenagers and young adults age 10 to 25. Among other findings, the data indicated that AIDS rates among boys age 15 to 19 increased from 1.3 cases per 100,000 in 1997 to 2.5 cases in 2006. The report also said that new HIV and AIDS diagnoses were highest among young blacks across all age groups (Chicago Tribune, 7/17). Kevin Fenton, director of CDC"s National Center for HIV/AIDS, Viral Hepatitis, STD and TB Prevention, said, "It is imperative that all of us at the national and community level work together to ensure STD and HIV prevention programs are reaching young people, particularly in communities with the greatest burden of disease" (Brewington, "Picture of Health," Baltimore Sun, 7/16).
