New aggressive strain of HIV discovered

Researchers have discovered a new, more aggressive strain of the human immunodeficiency virus (HIV) that develops into AIDS much more quickly than other strains, Medical News Today reported.
In a new study published in the Journal of Infectious Diseases, scientists detailed the new strain as a “recombinant” virus – a hybrid of two virus strains. Called A3/02 – a cross between the 02AG and A3 viruses – the strain can develop into AIDS in just five years after first infection – one of the shortest time periods for HIV-1 types.
"Recombinants seem to be more vigorous and more aggressive than the strains from which they developed,” said first author Angelica Palm, a doctoral candidate at Lund University in Sweden.
So far, the A3/02 strain has only been seen in Guinea-Bissau, West Africa, but other studies have shown that recombinants are spreading more quickly across the globe.
"HIV is an extremely dynamic and variable virus. New subtypes and recombinant forms of HIV-1 have been introduced to our part of the world, and it is highly likely that there are a large number of circulating recombinants of which we know little or nothing,” said senior author Patrik Medstran, professor of clinical virology at Lund University. “We therefore need to be aware of how the HIV-1 epidemic changes over time."

Some 131,000 people were newly infected with HIV in Europe and nearby countries in 2012, an 8 percent rise from a year earlier and a worrying reversal of a recent downward trend in AIDS cases in the West.
A report published by the World Health Organisation's (WHO) European office and the European Centre for Disease Prevention and Control (ECDC) showed a steady increase in new HIV cases over the last year, but by far the majority of cases were in Eastern Europe and Central Asia.
"The high and increasing number of AIDS cases in the East is indicative of late HIV diagnosis, low treatment coverage and delayed initiation of life-saving HIV treatment," the ECDC/WHO report said.
Some 76,000 new HIV infections were reported in Russia alone, accounting for more than half the region's cases.
While reported AIDS cases had been declining steadily in western Europe - dropping 48 percent between 2006 and 2012 - in the east of the WHO's European Region, which includes many Asian former Soviet republics, the number of people newly diagnosed with AIDS increased by 113 percent.
Experts said this increase was closely linked to a lack of prevention measures for people at high risk of contracting the human immunodeficiency virus (HIV) that causes AIDS.
These include clean needles and syringes for drug users, free condoms and easy access to HIV testing for sex workers and gay men, and early access to treatment with AIDS drugs - known as antiretroviral therapy (ART) - for those who test positive.
"Our data show that nearly every second person tested positive for HIV (in the region) - that's 49 percent - is diagnosed late in the course of their infection, which means they need antiretroviral therapy right away because their immune system is already starting to fail," said the ECDC's director Marc Sprenger.
Worldwide, more than 35 million people have HIV - the vast majority of them in sub-Saharan Africa where access to prevention, testing and drugs is often limited by low funds.
Cocktails and combinations of AIDS drugs can keep the virus in check for many years, allowing those who are diagnosed and treated early to live full and long lives.
Yet even in the relatively wealthy WHO European Region, only one in three people with HIV is getting the ART treatment they need, Wednesday's report said.
Michel Kazatchkine, the United Nation's HIV/AIDS Special Envoy in Eastern Europe, told Reuters in an interview this month that HIV epidemics are becoming more concentrated in marginalized groups such as sex workers, drug users and gay men, and could defy global attempts to combat AIDS if no progress is made in turning them around.
Sprenger said that to start to do that more effectively "we need to make HIV testing more available across Europe to ensure earlier diagnosis and more effective treatment and care".
Zsuzsanna Jakab, the WHO's regional director for Europe, said providing AIDS drugs earlier for those infected with HIV would allow them to live longer and healthier lives, and help reduce the risk that they transmit HIV to others.
"While we are not at the end of the HIV epidemic in Europe, our goal of halting and reversing the spread of HIV by 2015 is still achievable in many countries," she said.

(No) Condom Culture: Why Teens Aren’t Practicing Safe Sex

The percentage of young people using condoms has stalled, while STD rates are on the rise

There were certain things that the 1990s just did better — including getting the word out about the dangers of unprotected sex.
According to the Centers for Disease Control and Prevention (CDC), the percentage of American students using condoms hit its peak at around 60% a decade ago, and has stalled since then, even declining among some demographics. A recent study released by the Sex Information and Education Council of Canada found that nearly 50% of sexually active college students aren’t using condoms. Other reports have found that while teenagers are likely to use a condom the first time they have sex, their behavior becomes inconsistent after that.
Health officials from Oregon to Georgia are ringing alarm bells about rising rates of sexually transmitted diseases, worried that kids aren’t getting the message. Sex education is more robust than it was for previous generations, but a 2012 Guttmacher Institute report revealed that while nearly 90% of high schools are teaching students about abstinence and STDs, fewer than 60% are providing lessons about contraception methods.
The CDC estimates that half of new STD infections occur among young people. Americans ages 15 to 24 contract chlamydia and gonorrhea at four times the rate of the general population, and those in their early 20s have the highest reported cases of syphilis and HIV. Young men and women are more likely than older people to report having no sex in the past year, yet those who are having sex are more likely to have multiple partners, which increases the risk of STDs.
“We need to do better as a nation,” says Laura Kann, an expert in youth risk behaviors at the CDC. “Far too many kids in this country continue to be infected with HIV and continue to be at risk.”
When condom-usage rates were on the upswing in the ’90s, America was in the midst of an AIDS epidemic that was claiming young lives daily. The fear of the disease gave heft to safe-sex campaigns. Today, public-health officials are partly a victim of their own success; contemporary teenagers grew up after the terror had subsided, thanks to antiviral drugs and those messages that helped bring infection rates down. “The young people today know HIV as a manageable, chronic disease,” Kann says. “It’s not something that can kill you in their eyes. So that leads, most likely, to an attitude that it’s not something that they have to protect themselves from.”
In Oregon’s Lane County, senior health official Patrick Luedtke is in the midst of confronting an ongoing gonorrhea outbreak, with rates jumping as much as 40% in recent years. Like Kann, he believes complacency is a large part of the problem. “People don’t have the fear of death from sex like they had 15 years ago,” he says. “For the teenagers, that fear is gone, and people are not practicing safe sex as much as they used to.”
Other research collected by the CDC shows that some schools aren’t hammering away at the safe-sex lessons like they once did. In Alabama, Alaska and Florida, for instance, fewer public schools are teaching teenagers how to obtain condoms and why it’s important to use condoms. “Schools have competing health issues that they’re asked to deal with, things like tobacco use, bullying, the obesity epidemic. It’s been hard to keep attention focused on HIV and STD prevention,” Kann says. “This complacency issue [is not] unique to just youth themselves.” Last week, the American Academy of Pediatrics issued a policy statement supporting better access to condoms for teenagers, saying schools are still hesitant to provide them because of an enduring fear that access to condoms will make kids have more sex.
Public institutions beyond schools have had setbacks too. Budget cuts in Oregon meant that Luedtke’s county closed its STD clinic. “People don’t stop having sex because of the bad economy,” he says. “Where are the resources?”
Even in places where there’s money and free condoms to go around, health departments haven’t necessarily seen safe sex go viral. New York City health officials are reporting that only 1 in 3 adult residents uses protection, despite years of PSAs and prophylactic handouts under Mayor Michael Bloomberg. While condom use among young people in New York City is slightly up since 2009, that puts it on par with the stagnant nationwide average.
Kann says there are broader societal factors at work too, ones that disproportionately affect African-American youth. Compared with the population as a whole, their parents are less educated and have lower incomes, both factors that have been linked to sexually risky behaviors, including having unprotected sex. Adolescents who postpone sex have parents who are more educated. Lower incomes, meanwhile, are associated with factors like parents working multiple jobs, which can mean kids are left home alone without a watchful eye to factor into their decisionmaking.
Some research has suggested that sexually active Americans simply assume their partner is free of STDs, and an infected partner may be unaware, given that diseases like “silent” chlamydia often don’t have obvious symptoms. And there is a perception — if not a diehard belief — that using condoms makes sex less pleasurable. That’s why Bill Gates challenged designers earlier this year to create a better-feeling condom that sexually active people might be more likely to use.
While it’s hardly a sexy, revolutionary proposition like remaking the condom, Kann says the key to driving condom use higher is more education. Canada’s survey, for instance, was revealing about how relatively unimportant the students considered STDs. Those who used condoms were much more likely to cite pregnancy than STDs as their main concern; 54% said their single motivation for using protection was birth control, while just 6% cited STDs as their sole reason.
“It’s really critical for kids to know about their risk,” Kann says. “They need to know how to get tested. They need to know how to prevent infection. And we can’t do that alone here at CDC. We’re going to need action not only by this agency but also by parents, by schools and communities.”
