WHO Issues Antibiotic Alert

WASHINGTON
(AP) - The World Health Organization warned Monday that increasingly
drug-resistant infections in rich and developing nations alike are threatening
to make once-treatable diseases incurable.
Scientists have been urging action for years to fight the growing problem of
infections becoming impervious to treatment. The WHO's new report adds to the
alarm.
”We're losing windows of opportunity,” said WHO infectious diseases chief
Dr. David Heymann. “It's
something we have to really address immediately or we're going to start losing
our antibiotics.”
”This is a major problem for us, and it isn't going to go away,” added Dr.
Jeffrey Koplan, director of the U.S. Centers for Disease Control and Prevention,
who helped WHO unveil the report. “We
use the same antibiotics as other countries do,” so resistance in one country
is bad news for everybody.
Bacteria, parasites and viruses all naturally evolve to fight treatment. It's
classic survival of the fittest: Bugs exposed to drugs that don't kill them
become stronger, able to withstand subsequent treatment attempts, and pass on
that drug resistance to their next generation.
Misuse of medications, particularly antibiotics, speeds this process.
In developed countries, people often overuse antibiotics, demanding them for
viruses like colds. The body always harbors germs, so each unneeded antibiotic
dose is an opportunity for them to evolve. U.S. and Canadian doctors are
estimated to overprescribe antibiotics by 50 percent, the WHO report said.
Impoverished developing countries have the opposite problem. Many patients can't
afford the full course needed to cure an infection. Antibiotics may be sold at
market stalls where people buy a few doses without a doctor's exam.
In Vietnam in 1997, researchers found more than 70 percent of patients
were prescribed inadequate doses to cure serious infections.
Then there's misinformation: In the Philippines, people mistakenly use low doses
of an anti-tuberculosis drug as a “lung
vitamin,” WHO said.
Animals add to the problem. Half the world's antibiotics are used on the farm,
sometimes to treat illness but mostly to help healthy animals grow bigger. That
encourages drug-resistant germs that cause food poisoning, WHO said.
What effect does all this have? Among the report's sobering examples:
Gonorrhea was once easily curable with penicillin and tetracycline.
“Today, you can't touch it anywhere in the world with those drugs,”
Heymann said. Poor nations can't afford more expensive alternatives and, to make
matters worse, untreated gonorrhea is fueling spread of the AIDS virus.
In Estonia, Latvia, and parts of Russia and China, more than 10 percent of
tuberculosis patients have strains resistant to two powerful medicines. Overall,
up to 2 percent of the world's 16 million TB sufferers have multi-drug resistant
strains, particularly frightening because TB is airborne, spread when people
cough.
Malaria, the mosquito-spread infection that kills a million people a year, is
resistant to the top medication 80 percent of the time.
Some 5,000 Americans may have suffered longer-lasting food poisoning in 1998
from drug-resistant germs in chicken.
Nobody counts deaths from drug-resistant infections. The CDC says 88,000
Americans a year die of infections they catch in the hospital, and many are
resistant to at least one antibiotic, complicating treatment attempts.
Wiser use of antimicrobial drugs is the solution, the WHO said. It recommended
increased funding to help poor countries afford enough antibiotics, and
education for poor and rich nations alike to avoid misuse.
WHO also recommended that human antibiotics not be used as growth promoters for
animals. Europe already has banned
several such drugs. The U.S. Food and Drug Administration has debated stricter
rules here for several years, but is under industry pressure not to tighten
animal drug restrictions.
