Treating intravenous drug users with antiviral drugs may reduce their chances of HIV infection, according to a new study published Wednesday in the British medical journal The Lancet.
The Bangkok Tenofovir Study was done in Bangkok, Thailand, from 2005-2013. It was run by the Centers for Disease Control and Prevention in collaboration with the Thailand Ministry of Public Health.
Researchers recruited more than 24,000 people at 17 sites. Half took the pill tenofovir - an antiretroviral drug – daily, while the other half got a placebo. Participants were followed for about four years. Researchers found those taking the drug cut their chances of infection by 49% almost in half - approximately 49%.

There are about 20 million new sexually transmitted infections (STIs) each year in the United States, costing some $16 billion in direct medical costs, according to numbers released Wednesday by the Centers for Disease Control and Prevention.
Young people are disproportionately affected, the agency said, with half of all new infections occurring in people ages 15 through 24.
"In general, CDC estimated the total number of infections in the calendar year, rather than the number of individuals with infection, since one person can have more than one STI at a given time" or more than one episode of a single STI, officials said. But "CDC used conservative assumptions in generating its estimates, so the true numbers of STIs in the United States may be even higher than estimated." FULL POST

If you haven't received your flu shot yet, the Centers for Disease Control and Prevention says now is the time to make sure you're protected. The agency says flu season is ramping up early this year - for the first time in almost a decade.
According to CDC Director Dr. Thomas Frieden, H3N2 is the predominant strain this year. It's generally associated with a severe flu season. "The strains we are seeing suggest this could be a bad flu year," Frieden said. "But this year's vaccine is an excellent match with the influenza that's circulating."

Almost a quarter of new HIV cases are seen in young people, and more than half of them don't know they're infected, says a new report from the U.S. Centers for Disease Control.
According to the report, more than 12,000 new cases occurred in young people aged 13 to 24 in 2010, and close to 60% of them did not know their HIV status.
"That so many young people become infected with HIV each year is a preventable tragedy," wrote CDC Director Dr. Thomas Frieden in the report. FULL POST

The odds are increasing that you or someone you know has Type 2 diabetes. The latest Morbidity and Mortality report (MMWR) released by the Centers for Disease Control and Prevention shows that from 1995 to 2010, there was at least a 100% increase in the prevalence of diagnosed diabetes cases in 18 states. Forty-two states saw an increase of at least 50%.
"Even when you know that [the prevalence of diagnosed diabetes] is increasing, to see that level of increase was shocking to me," says Linda Geiss, a statistician with CDC's Division of Diabetes Translation and the lead author of the MMWR.
"It was the 100% figure. 100% – that's a large increase."
Predictably, states in the South where obesity levels have also steadily increased had some of the highest increases in diabetes. Oklahoma topped the list with an increase of 226%, followed by Kentucky with 158%, Georgia with 145%, Alabama with 140% and the state of Washington with 135%.

The number of teenagers who are drinking and driving has dropped by 54% in the past two decades, according to a new report released Tuesday by the Centers for Disease Control and Prevention.
In 2011, when asked if they drink and drive, 90% of the high school students 16 and older surveyed by the CDC said they did not.
However, “motor vehicle crashes remain the leading cause of death among teens in this country. There are more than 2,000 teens aged 16-19 killed each year and many of those deaths are alcohol-related,” said CDC Director Dr. Thomas R. Frieden. “Almost a million high school teens aged 16 and over drove after drinking alcohol in 2011 and we calculate that high school teens were responsible for about 2.4 million episodes of drinking and driving a month.”

Flu season has officially started and although most influenza cases don’t begin to pop up till late October, doctors say September is a perfect time to get vaccinated. And that includes getting shots for your youngsters and teens.
This week, the American Academy of Pediatrics released its new guidelines on influenza and children. Although there are no major changes, the group stresses it’s important for parents to talk to their child’s pediatrician about the vaccine.
Over the past few years, the Centers for Disease Control had recommended that children over the age of six months get either a traditional flu shot or a LAIV (live attenuated intranasal vaccine) sprayed in the nose, also known as FluMist. That has not changed. But because of the configuration of this year’s vaccine, the AAP is recommending parents be aware of how many shots their children should have.

They are used to power everything from flashlights to remote controls. So called "button batteries," which are the size of coins (and sometimes smaller), have grown in popularity over the past few decades. Now, the Centers for Disease Control is warning parents to keep them away from children.
According to this week's Morbidity and Mortality Weekly Report, approximately 40,400 children aged 12 and younger were treated in emergency rooms for battery-related injuries between 1997 and 2010
But here's the bigger concern: 14 children, all of them under the age of 4, died after swallowing batteries. Twelve of the 14 deaths involved button batteries. In most cases, the batteries got stuck in the esophagus. Experts say when that happens, or if the batteries make it down to the intestine, they can emit hydroxide which can cause chemical burns.

Fewer teens aged 15 to 17 are having oral sex now than in 2002, according to a new report from the U.S. Centers for Disease Control, but the number remains high.
The report, based on data from The National Survey of Family Growth, found that more than a third of teens had engaged in oral sex by the time they turned 17. That number climbed to almost 50% by age 19, and more than 80% for 24-year-olds.
The study - based on computer surveys given to over 6,000 teens - also looked at the timing of first oral sex in relation to the timing of first vaginal intercourse. It found that the prevalence of having oral sex before vaginal intercourse was about the same as those having vaginal intercourse before oral sex.

It's almost the beginning of summer and you know what that means: Swim season is here. But beware. No matter how clean they may look, public pools could have nasty germs lurking in the water causing them to be more like public bathrooms.
A recent survey conducted by the Water Quality and Health Council found one in five Americans admit to using a public pool for quick relief (urinating) and seven in 10 confessed to skipping a shower before going for a swim.
According to the Centers for Disease Control and Prevention, a pre-swim shower removes sweat, cosmetics and other dirt that could mix with chlorine to create irritants in pool water.
