DRUG-RESISTANT TB JUMPS IN GERMANY, DENMARK, NEW ZEALAND|
By JOHN DONNELLY|
WASHINGTON Deadly drug-resistant tuberculosis, a highly
infectious disease, is spreading more rapidly from poor
nations to rich ones, raising a new health concern for
the Western world, researchers say. The infection
rate, though still low, jumped 50 percent in one year in Germany
and Denmark, and it doubled in New Zealand, according to a report being released Friday in Amsterdam by the World Health Organization and the
International Union Against TB & Lung Disease. Its a warning to the developed world, said
Nils Daulaire, president of Global Health Council, an
alliance of global health-care advocates. There are hot spots nowdeveloping and if we dont deal with it immediately,
its only going to get much worse.
While drug-resistant tuberculosis has taken root in many of the
worlds poorest countries, global health experts
believe the fight against TB will not fully begin until
it spreads to the wealthiest countries and those nations
see it as a national security threat, and begin spending billions of dollars to defeat it everywhere. Tuberculosis,
which spreads through the air when an infected person coughs, sneezes or spits, kills about 1.5 million people a year, 98 percent of them
in developing countries. The Mycobacertium tuberculosis bug develops
immunities to the most common drugs if the treatment isnt
completed or is improperly administered. But even as reports in recent years circulated about frightening epidemics
of drug-resistant TB in Russian prisons and slums in every continent,
no one knew the rate at which the infectious disease was
growing, or whether treatment was helping. For the first time, the 117-page report establishes the beginnings of a
baseline of information about the drug-resistant TB bug, comparing
data from 1994 to 1999, and it showed that proper
treatment had slowed the spread of drug-resistant TB.
Yet, several areas reported alarming increases in
drug-resistant TB, including Estonia; the Henan and
Zhejiang provinces of China; the Tamil Nadu region in
India; Iran; Mozambique; and Russia. Other countries reporting that drug-resistant TB accounts for more than 6
percent of all TB cases were Israel, Italy and Mexico.
The United States has reported only a handful of cases, and
almost all of them are transmitted by foreign travelers,
officials said. The numbers of cases in wealthy countries
still remains relatively small Germany has about
100 people infected with drug-resistant TB but only a few
years ago there were no cases. WHOs recommendation will be to increase by threefold a program
treating people with easily curable TB. The program is
called directly observed treatment, or DOTS. The
organization also supports several pilot projects to treat
those with drug-resistant TB.
Only a few years ago, the WHO said in a report that those who contract drug-resistant TB in poor countries would almost surely die because of the high cost of drugs. In response, a Cambridge, Mass. group called Partners in Health started a project in Lima, Peru, in which it cured more than 100 people in the Carabayllo slum who had drug-resistant TB. The cost per patient then was up to $10,000. Now, according to Jim Yong Kim, the groups executive director, the price of the drugs should drop to about $500 per patient as a result of negotiations with the pharmaceutical industry and WHOs reversal to a position that poor people with the illness could be cured, which created a market for the drugs. Kim, in a telephone interview from Amsterdam, where he is attending a TB conference, applauded the WHO report, saying it marks a real change in its policy that DOTS alone cannot solve the TB epidemic. Tuberculosis is dormant in most people, activated almost always when a persons immune system weakens. TB kills large numbers of people with HIV even in countries such as Botswana that have good anti-TB programs.
