Nearly half of HIV-positive young people don’t realize that they’ve been infected, according to U.S. health officials. In fact, says the U.S. Centers for Disease Control and Prevention, fewer than a quarter – 22 percent – of sexually active high school students are tested for the virus, which causes AIDS. “At the end of 2006, an estimated 48 percent of adolescents and young adults infected with HIV were unaware of their infection, representing missed opportunities for diagnosis, treatment, and reduction in the number of new HIV transmissions,” the CDC said. Using data from a 2007 survey of ninth- to 11th-graders, the CDC found that people ages 12 to 24 represented 4.4 percent of the estimated 1.1 million people in the United States infected with HIV. Still, that number represented 10 percent of the estimated 232,700 people living with the virus without knowing it. The CDC recommends that doctors offer HIV screening as part of routine checkups for U.S. high school students.

Sexually transmitted diseases are on the rapid rise throughout the United States, reports Mary Engel of The Los Angeles Times. She writes in Wednesday’s edition that: “Rates of the sexually transmitted disease chlamydia are climbing in the U.S., and rates of syphilis – once on the verge of elimination – rose for the seventh consecutive year, the Centers for Disease Control and Prevention said Tuesday in its annual report on STDs.

Government doctors fight staph infection.

Just as NBA Star Grant Hill rallies others who have experience with the flesh-eating staph infection known as MRSA, the U.S. Centers for Disease Control and Prevention launched a campaign to make parents more aware of the dangerous and potentially deadly effects of methicillin-resistant staphylococcus aureus (MRSA). The government campaign hopes to get parents to identify, prevent and combat the infection. Often mistaken for a spider bite as the symptoms, MRSA also causes painful, red, swollen areas on skin that sometimes ooz puss, experts say. MRSA infection begins as a bump or infected area on the skin, is warm to touch and maybe accompanied by fever. It is contracted when someone touches an infected area or shares a personal item with someone who is already infected. Athletes are more prone to this infection, but it is also common at hospitals. To prevent the disease, the CDC advises frequent hand-washing, no sharing of personal items such as towels and to keep any wound or cut clean and bandaged. Early detection is always advisable as the infection at a later stage becomes difficult to treat. As part of the awareness campaign, the CDC hopes to develop Web sites, brochures, fact sheets, posters, radio and print public services, Web banners and mom-blogging sites.

Study: Fast-Food Ads Target Blacks.   A higher exposure to fast-food ads and marketing of other fatty foods is in part to blame for why overweight and obesity rates are such a bigger problem for African Americans (68.9 percent) than for Whites (59.5 percent), says the numbers crunched by the Kaiser Family Foundation.

Blacks with lung disease have twice the cancer risk. Blacks with chronic obstructive pulmonary disease – including chronic bronchitis and some types of serious chronic asthma – have twice the risk of developing lung cancer than Whites with the condition, according to a study published in the journal Cancer Prevention Research, Reuters reports. For the study, lead researcher Carol Etzel of the University of Texas M.D. Anderson Cancer Center and colleagues developed a risk assessment model to help predict Blacks’ risk for lung cancer. Researchers analyzed data on 491 Blacks with lung cancer and 497 Blacks without the disease and compared those numbers against models that measured the disease in Whites. Researchers said the model will help doctors better predict lung cancer risk. The new model found that Black men with a history of chronic lung disease, often called COPD, had a more than a six-fold increased risk of developing lung cancer, which is about the same risk for those who smoke. According to Reuters, both Black and White smokers have a risk of lung cancer six times higher than that of non-smokers. Smoking is the leading cause of COPD, but pollution, and other environmental factors also play a role, Reuters reports. “What we hope is that a doctor can use these models to encourage their patients to take steps to prevent lung cancer,” Dr. Ezel says. “Even if they are never smokers, they can be at risk.”
