HIV among injection drug users declines

U.S. health officials say the rate has dropped by half since the 1990s. The decline may be related to a growth in needle exchange programs. For the report more than 10,000 drug users in 20 metropolitan areas were surveyed and tested for HIV in 2009. About 1 in 10 tested positive for the virus. In the '90s, roughly 1 in 5 did. Addicts who inject heroin, cocaine or other drugs have been one of the groups hit hardest by AIDS.

WHO, PAHO release new guidelines on mosquito-borne chikungunya virus

The Pan-American Health Organization (PAHO), a regional arm of the World Health Organization (WHO), on Tuesday "unveiled new guidelines to help countries throughout the Americas detect and prevent transmission of the mosquito-borne chikungunya virus -- a disease which has already infected more than two million people around the world," the U.N. News Centre reports.

Ten symptoms and signs that a child may need a doctor

Unfortunately, kids get sick. Fighting a virus or common cold is good for a child's immune system and can help build antibodies that protect them from dangerous illnesses. Still, there are times when that tummy ache or cough may require medical attention.

Longer looks: Romney's evolution on abortion; The birth of the HIV epidemic

GOP presidential candidate Mitt Romney began his political career as a pro-choicer. In the story he tells, he had an epiphany, a flash of insight, and committed himself thereafter to protecting life. But that isn't what happened. The real story of Romney's conversion - a series of tentative, equivocal, and confused shifts, accompanied by a constant rewriting of his past - paints a more accurate picture of who he is.

U.S. panel may re-evaluate bird flu research after scientists present new data about risks to humans

Speaking at the American Society for Microbiology's (ASM) Biodefense and Emerging Diseases Research meeting in Washington, D.C., on Wednesday, Ron Fouchier, the leader of the team at Erasmus Medical Center in the Netherlands that genetically altered the H5N1 bird flu virus, making it transmissible among ferrets and "touching off public fears of a pandemic, said that the virus he created was neither as contagious nor as dangerous as people had been led to believe, prompting the United States government to ask that the experiments be re-evaluated by a government advisory panel that recommended in December that certain details of the work be kept secret and not published," the New York Times reports.

CD4 T cells can directly kill HIV-infected cells

A subpopulation of the immune cells targeted by HIV may play an important role in controlling viral loads after initial infection, potentially helping to determine how quickly infection will progress. In the February 29 issue of Science Translational Medicine, a team of researchers from the Ragon Institute of Massachusetts General Hospital (MGH), MIT and Harvard describe finding a population of HIV-specific CD4 T cells - cells traditionally thought to direct and support activities of other immune cells - that can directly kill HIV-infected cells.

Glucose meter could be adapted to monitor DNA

An inexpensive device used by millions of people with diabetes could be adapted into a home DNA detector that enables individuals to perform home tests for viruses and bacteria in human body fluids, in food and in other substances, scientists are reporting in a new study.

NKT cells may reduce monocytes accumulation, prevent lung injury in severe flu

While some scientists report engineering a super virulent strain of the H5N1 influenza virus, which could potentially wipe out a significant percentage of the human population, another group of researchers from the United Kingdom now reports a discovery that may one day help mitigate the deadly effects of all flu strains.

HPV and smear tests offer more effective approach for cervical screening

Testing for the human papillomavirus (HPV) - a virus most women will encounter at some point in their lives - followed by a smear test if they are HPV positive, provides the most effective approach for cervical screening, new research shows today.

Ultrasound-based TE more accurate in detecting hepatic fibrosis

Researchers from the Mayo Clinic confirm that ultrasound-based transient elastography (TE) provides excellent diagnostic accuracy for detecting cirrhosis due to recurrent infection with hepatitis C virus (HCV) infection following liver transplantation.

First clinical assessment of how interferon fights infections in people

A drug once taken by people with HIV/AIDS but long ago shelved after newer, modern antiretroviral therapies became available has now shed light on how the human body uses its natural immunity to fight the virus—work that could help uncover new targets for drugs.

Health indicator reports show more HIV-positive South Africans receiving care but costs increasing

Two new reports from southern Africa's Health Systems Trust show that pregnant women, infants, and people newly diagnosed with HIV infection are receiving more services, but the costs of care are increasing, PlusNews reports.

WUSM to study children with weakened immune systems

Not all viruses make us sick. But which ones are friends and which ones are foes? Researchers at Washington University School of Medicine in St. Louis have received a five-year, $3.3 million grant to study children with weakened immune systems to identify the viruses that make children sick.

IDWeek 2012 to take place October 17-21 in San Diego

Abstracts are now being accepted for IDWeek 2012, the first-ever combined meeting of the Infectious Diseases Society of America (IDSA), the Society for Healthcare Epidemiology of America (SHEA), the HIV Medicine Association (HIVMA), and the Pediatric Infectious Diseases Society (PIDS).

HPV vaccine now recommended for boys: American Academy of Pediatrics

Pediatricians in the U.S. say it's now time for boys, as well as girls, to be vaccinated against human papillomavirus or HPV. The American Academy of Pediatrics has updated its guidance to parents and doctors in favor of routine immunization for boys against the virus. Earlier the AAP had said it was OK to vaccinate boys against the HPV, but it only became part of the pediatricians' official schedule of recommended vaccines this month.

Scientists find evidence of a ‘different’ flu virus in bats

They were surprised to find genetic fragments of a flu virus in bats. So far, scientists haven't been able to grow it, and it's not clear if — or how well — it spreads. Flu bugs are common in humans, birds and pigs and have even been seen in dogs, horses, seals and whales, among others. About five years ago, Russian virologists claimed finding flu in bats, but they never offered evidence.

Rapid influenza diagnostic tests highly accurate in children than in adults

A new study conducted by researchers from McGill University, the Research Institute of the McGill University Health Centre (RI MUHC), and Sainte-Justine University Hospital Research Centre, Montreal, has put the accuracy of rapid influenza diagnostic tests (RIDTs) under the microscope.

WHO removes India from list of countries with endemic Polio

India is nearly free of deadly paralyzing viral infection polio. Health Minister Ghulam Nabi Azad says the WHO removed India from the list Saturday after the country passed one year without registering any new cases. This means only three countries with endemic polio — Pakistan, Nigeria and Afghanistan. India must pass another two years without new cases to be declared polio-free.
