More than a quarter of new HIV infections in the U.S. occur among people ages 13 to 24, according to a new report released Tuesday by the Centers for Disease Control and Prevention. What's more, about 60% of those young people with HIV don't know they have the virus. The release represents the most recent analyses by the CDC. It was timed to coincide with World AIDS Day, which is Dec. 1. According to the CDC, about 12,200 young Americans became infected with HIV in 2010, with African Americans representing more than half of those newly infected.

HANALEI, Hawaii - When compiling a list of places that may be described as paradise, Hanalei Bay on the rugged north shore of the island of Kauai surely qualifies. The perfect crescent bay, rimmed by palm trees, emerald cliffs and stretches of white sand, has always had a dreamy kind of appeal. It was on these shores that sailors in the movie "South Pacific" sang of the exotic but unattainable "Bali Ha'i. " The problem is what lies below the surface of the area's shimmering blue waters.

The U.S. Centers for Disease Control and Prevention said there were no new reports of fungal meningitis linked to tainted steroid injections responsible for dozens of deaths nationwide, closing the window of all known cases in a 42-day period ended Wednesday. “People can rest a little easier but still remain vigilant,” CDC spokesman Curtis Allen told the Los Angeles Times. “What we're finding is that the further out you go from the last injection, the less the risk.” Wednesday was the end of the 42-day peak risk period since the CDC recalled the steroids Sept.

LONDON - Malala Yousafzai, the Pakistani teenage education-rights campaigner who was shot in the head by the Taliban, has been able to stand for the first time since the attack and is communicating by writing, a British hospital official said Friday. But the 14-year-old whose plight has aroused international concern is still fighting an infection caused by the bullet that entered her head, burrowed past her jaw and lodged above her shoulder blade, said David Rosser, medical director at Queen Elizabeth Hospital in Birmingham, in central England.

A 34-year-old man died in Switzerland this summer from rabies contracted from a bat in Contra Costa County - the first such death traced to the county in nearly 20 years, officials announced Friday. The man, whose name has not been released, became ill before leaving the United States to work overseas. He died in a hospital in July, according to Contra Costa Health Services. Tests confirmed rabies as the cause of death. The national Centers for Disease Control and Prevention was notified of the death in late August and launched an investigation.

If you're trying to ward off the sniffles, you can take vitamin D supplements out of your shopping cart: A new study reports that dosing with the vitamin does nothing to prevent colds or other forms of upper respiratory tract infections (URTI). The effect of vitamin D on the immune system has been debated for a long time. Controlled laboratory research has shown that vitamin D has several beneficial effects on the immune system, and some studies conducted in the past have suggested that people with low levels of the vitamin are at higher risk for URTIs.

A new study suggests that a physician's gut feelings -- a sense that something is wrong even when everything checks out in the standard clinical exam -- may contain more information than he or she gives them credit for. A growing literature has begun to ask whether such gut feelings add anything substantive to a doctor's clinical exam. But in general the studies have been limited by a shaky understanding of just what is meant by gut feeling -- specifically, which aspects of a patient visit lead to a doctor's gut feeling that are not part of the standard clinical exam.

Another person has been sickened by hantavirus originating in Yosemite National Park, the ninth case in a rash of the rodent-borne disease that has killed three visitors since mid-June. The latest case sickened a California resident who stayed in a Curry Village "signature tent cabin" in early July, park spokesman Scott Gediman said. The person has since recovered, he added. But the latest case was a milder infection, with flulike symptoms that did not advance to hantavirus pulmonary syndrome, the respiratory ailment that can prove fatal, according to park and health officials.

Last fall, Dena Harris went to a rehab facility to visit her 90-year-old mother, who was recovering from a broken hip. Harris knew something wasn't right: Her mother's skin was pale and her eyes glassy. The doctors diagnosed her with a raging gut infection of Clostridium difficile , a nasty bacterium that causes watery diarrhea. The Centers for Disease Control and Prevention estimates that C. difficile kills 14,000 people each year in the U.S. alone. Harris' mother, Ann Hart, received the standard treatment - a hefty dose of antibiotics - but the drugs provided only temporary relief.

The population of mice that carry hantavirus may have swelled in Yosemite National Park, a possible lead in the ongoing investigation into an outbreak of infections that has killed three people since mid-June. Recent trapping related to the investigation indicates that the park's deer mouse population is larger this year, said Dr. Vicki Kramer, head of the California Department of Public Health's vector-borne disease section. Deer mice are the primary carriers of hantavirus in the U.S. Agency officials have twice laid peanut butter-laced traps for the rodents at the park, Kramer said.
