Transitioning to an AIDS-Free Generation There was much to celebrate on World AIDS Day last week. Over the last decade, an unprecedented surge in donor support for HIV/AIDS treatment has lengthened and improved the lives of millions of people living with the disease. The number of people receiving antiretroviral treatment worldwide stands at more than six million in 2011, a 16-fold increase since 2003.
Will we ever have an HIV vaccine? | Not Exactly Rocket Science Here’s the seventh piece from my new BBC column For around 30 years we have lived under the spectre of HIV. In the early 1980s, the mysterious appearance of symptoms that would later be known as AIDS led to unprecedented efforts to unmask the cause.
Breast milk seems to kill HIV - health - 15 June 2012 Breast milk is starting to look like a potent HIV-fighter. An unknown component of breast milk appears to kill HIV particles and virus-infected cells, as well as blocking HIV transmission in mice with a human immune system. Even if babies born to HIV-positive mothers avoid infection during birth, around 15 per cent contract HIV in early childhood.
Facebook: The next tool in fighting STDs Imagine being able to download a Facebook app that would alert you to your sexually transmitted infection risk based on your friend’s status updates. This may sound far-fetched, and it still is, but as some researchers shift their focus to risk among friend groups, as opposed to just sexual partners, social networks are rapidly becoming a tool to prevent the spread of STIs. Peter Leone, a professor of medicine at the University of North Carolina’s Center for Infectious Diseases, is one of those experts.
Timeline: A Few Landmarks In the Effort to Treat AIDS
Colonialism in Africa helped launch the HIV epidemic a century ago As to the why, here is where the story gets even more fascinating, and terrible. We typically think of diseases in terms of how they threaten us personally. But they have their own stories. Diseases are born. They grow.
There is a lot of optimism now in the community of public-health officials and advocates who work on AIDS. People are being treated with more effective medicine in more places and in greater numbers around the world than many ever thought possible. The world is getting smarter about outsmarting the AIDS virus. But, even as we know more, there are still disputes about how best to move forward on both prevention and treatment. Such is the nature of AIDS, especially as it involves an attempt to understand the complexity of human behavior as it relates to sex. News Desk: The Changing AIDS Epidemic—and What to Do Next
In January, India marked an incredible achievement: one year since the country's last reported case of polio. That is cause for celebration -- not just in India but around the world. Twenty years ago, there were more than 100 polio-endemic countries; now, only three remain. Such a victory over polio seemed almost impossible just a decade ago. India's tropical climate is conducive to the survival and spread of the disease. Meanwhile, India's dense, ethnically and linguistically diverse population made it difficult for the government to reach its most at-risk citizens. India's Polio Win

Losing Polio - By Laurie Garrett Last week, a Pakistani doctor was sentenced by his government to three decades in prison for actions that helped the United States kill Osama bin Laden. Meanwhile, in far-off Geneva, the World Health Organization (WHO) declared a state of emergency in its decades-long battle to eradicate polio. That these two events are intimately connected speaks volumes about new challenges -- political ones -- that threaten to undermine extraordinary global health achievements. A tribal court in Peshawar sentenced Dr. Shakil Afridi to 33 years' imprisonment for treason -- a penalty considered mild given that the nontribal Pakistani government courts would have ordered death by hanging for the same alleged crime.
Vaccine development: Man vs MRSA Robert Daum has shown that MRSA is not confined to hospitals — and is determined to find a vaccine that will fight the bacterium. Over the years, Robert Daum has learned to respect his adversary. In 1995, he and his co-workers at the University of Chicago children's hospital in Illinois were investigating infections that had affected two dozen children in their emergency department. Three children had fast-moving pneumonia.
It all happens in a femtosecond – a quadrillionth of a second. That's the time an enzyme needs to shape-shift into its most reactive form, trigger a chemical reaction and snap back into its original shape. We can now enter this high-speed world to interrupt the chemical reactions that sustain some of our deadliest pathogens and cause disease. Doing so could lead to antibiotics that won't trigger bacterial resistance. Superfast drugs target shape-shifting enzymes - health - 13 March 2012

Hidden Epidemic: Tapeworms Living Inside People's Brains | Infectious Diseases Theodore Nash sees only a few dozen patients a year in his clinic at the National Institutes of Health in Bethesda, Maryland. That’s pretty small as medical practices go, but what his patients lack in number they make up for in the intensity of their symptoms. Some fall into comas.
As Diseases Make Comeback, Why Aren't All Kids Vaccinated? Progress is easy to take for granted. When I was a child in the '60s, polio was history, measles was on the way out, and diphtheria and whooping cough were maladies out of old movies. Now these contagious diseases are making a comeback. Take measles, for instance.
