Drug-resistant superbug hits U.S.
A dreaded superbug found for the first time in a U.S. woman
Story highlights
- It is the first U.S. case of a bacterial infection that is resistant to all known antibiotics
- The CDC director warns that we may see more of these cases
- Dr. Tom Frieden urges the scientific community to develop new drugs
(CNN)The
United States' first known case of a superbug that cannot be killed by a
last resort-style kind of antibiotic was detailed in a report by the
U.S. Department of Defense on Thursday.
Centers
for Disease Control and Prevention Director Dr. Tom Frieden announced
the case at the National Press Club in Washington.
A 49-year-old Pennsylvania woman showed the presence of
a rare kind of E. coli infection that is resistant to antibiotics, even
Colistin, which doctors sometimes use as a last resort when other
antibiotics fail.
The
woman went to a clinic in Pennsylvania, and a sample was forwarded to
Walter Reed National Military Medical Center. Walter Reed found the
bacteria in her urine. No other details were available, including how
the woman became infected. She has not traveled outside the United
States within the past five months.
The
CDC and the Pennsylvania State Health Department mobilized immediately
to investigate the case and to trace the contacts the patient may have
had to see if the bacteria had spread.
The CDC also said it is looking for other potential cases in the health care facility the patient visited.
The bacteria have been identified in other infections outside the United States. Doctors saw cases in Europe, Canada and China.
One report suggests that this kind of infection can result in the deaths of half the patients who become infected.
Antibiotic resistance has become a growing problem in this country. The World Health Organization has warned that it is one of the biggest threats to global health today.
Frieden
warned that although this is the first case in the United States, we
should expect to see more such superbugs in the near future. Frieden,
who often warns doctors against overuse of antibiotics, urged scientists
to develop new drugs quickly.
Each
year in the United States, at least 2 million people become infected
with other kinds of bacteria that can't be beaten with most antibiotics,
and at least 23,000 people die each year as a result of those
infections, according to the CDC.
"The medicine cabinet is empty for some patients," Frieden said. "It is the end of the road unless we act urgently."
