VOA标准英语2010年-US Government Highlights Antibiotic Mi

（单词翻译）

A leading U.S. government health agency is focusing an annual campaign on educating patients, parents, and health care providers about the need to avoid the misuse¹ of antibiotics³. Inappropriate use of antibiotics can lead to "superbugs" that resist drugs.
The Centers for Disease Control and Prevention (CDC) is marking the third week in November as "Get Smart About Antibiotics Week." The agency wants to draw attention to the misuse of these powerful drugs, such as when a doctor prescribes an antibiotic² for something other than a bacterial⁴ infection, or when patients don't take the medicine as instructed.
The medical director for the CDC program, Lauri Nicks, DO, says antibiotics are over-prescribed for a variety of reasons.
"We're seeing that doctors are over-prescribing because of patient expectations, because of fear of making the wrong diagnosis," she says. "And, of course, patients are demanding antibiotics in many cases from their providers as well."Antibiotics can also be misused⁵ when the drugs are not taken under expert supervision⁶. In many countries, antibiotics require a doctor's prescription⁷. But Hicks says that's not true everywhere.
"In certain areas, antibiotics can be obtained without prescription, so there may be more inappropriate antibiotic use in some of those settings."The CDC says about half the antibiotics used in the U.S. each year are prescribed unnecessarily, costing more than a billion dollars in the United States alone.
Overuse of antibiotics can lead to drug-resistant⁸ bacteria that have to be treated with more powerful and often more expensive drugs. And sometimes there are no drugs that work effectively, which increases the danger to people who are infected.
The U.S. campaign for the smart use of antibiotics parallels similar efforts in Europe and Canada, which Hicks says underscores the international nature of the threat.
"Resistant bacteria don't respect country or national boundaries and can easily travel on planes. Antibiotic resistance anywhere is really antibiotic resistance everywhere."
