SAN FRANCISCO (Reuters) - A drug-resistant strain of potentially deadly bacteria has moved beyond the borders of U.S. hospitals and is being transmitted among gay men during sex, researchers said on Monday.
They said methicillin-resistant Staphylococcus aureus, or MRSA, is beginning to appear outside hospitals in San Francisco, Boston, New York and Los Angeles.
Sexually active gay men in San Francisco are 13 times more likely to be infected than their heterosexual neighbors, the researchers reported in the Annals of Internal Medicine.
"Once this reaches the general population, it will be truly unstoppable," said Binh Diep, a researcher at the University of California, San Francisco who led the study. "That's why we're trying to spread the message of prevention."
According to chemical analyses, bacteria are spreading among the gay communities of San Francisco and Boston, the researchers said.
"We think that it's spread through sexual activity," Diep said.
This superbug can cause life-threatening and disfiguring infections and can often only be treated with expensive, intravenous antibiotics.
It killed about 19,000 Americans in 2005, most of them in hospitals, according to a report published in October in the Journal of the American Medical Association.
About 30 percent of all people carry ordinary staph chronically. It can be passed by touching other people or by depositing the bacteria on surfaces or objects.
The bacteria can cause deep-tissue infections if they enter the body through a wound in the skin.
Of those people who carry staph, most carry it in their noses but community-based MRSA also can live in and around the anus and is passed between sexual partners.
Incidence of MRSA is rising along with the resurgence of syphilis, rectal gonorrhea, and new HIV infections partly because of changes in beliefs about the severity of HIV and an increase in risky behaviors, such as illicit drug use and having sex that abrades the skin, Diep's team wrote.
"Your likelihood of contracting each of these diseases increases with the number of sexual partners that you have," Diep said. "The same can probably be said for MRSA."
Staph infections often look like raised red dots on the skin. Left untreated, the areas can swell and fill with pus.
The best way to avoid infection is by washing the hands or genitals with soap and water, Diep said.

MRSA：同性恋之间院外散播
SAN FRANCISCO (Reuters) - A drug-resistant strain of potentially deadly bacteria has moved beyond the borders of U.S. hospitals and is being transmitted among gay men during sex, researchers said on Monday.
圣弗朗西斯科（路透社）----周一研究人员声称，在美国一种可能致死的耐药菌株已经扩散到医院外，在同性恋者之间传播。
They said methicillin-resistant Staphylococcus aureus, or MRSA, is beginning to appear outside hospitals in San Francisco, Boston, New York and Los Angeles.
他们说，在圣弗朗西斯科、波士顿、纽约和洛杉矶耐甲氧西林金黄色葡萄球菌（MRSA）已经扩散到医院外。
Sexually active gay men in San Francisco are 13 times more likely to be infected than their heterosexual neighbors, the researchers reported in the Annals of Internal Medicine.
研究者在《内科学年鉴》（Annals of Internal Medicine）中发文指出，在圣弗朗西斯科性行为活跃的同性恋者感染MRSA的几率是其异性恋邻居的13倍多。
"Once this reaches the general population, it will be truly unstoppable," said Binh Diep, a researcher at the University of California, San Francisco who led the study. "That's why we're trying to spread the message of prevention."
圣弗朗西斯科加利福尼亚州大学主持这项研究的研究者Binh Diep说：“一旦细菌传播到普通人群中，真的将无法阻止。这是我们尽力传布预防信息的原因。”
According to chemical analyses, bacteria are spreading among the gay communities of San Francisco and Boston, the researchers said.
研究者们说，按照化学分析细菌在圣弗朗西斯科和波士顿的同性恋者间传播。
"We think that it's spread through sexual activity," Diep said.
Diep说：“我们认为是通过性交传播的。”
