Drug-resistant TB sweeps India
Country, China Account For
50% Of Disease
 New
Delhi: Drug-resistant TB, which does not respond to the most
effective drugs, is fast sweeping through the world. What’s
worse, India and China are home to 50% of the globe’s multi-drug
resistant TB (MDR TB) cases.
According to WHO’s global report on drug-resistant TB
released on Friday, an estimated 4.4 lakh people globally got
infected with MDR TB in 2008 while 1.5 lakh died of it.
Worldwide, there were an estimated 9.4 million cases of new TB
cases in 2008 with 1.8 million deaths.
India estimates that 3% of all new TB cases in the country
can’t be treated with standard drug regimens. Worldwide, of
those patients receiving treatment, 60% were cured. However,
only an estimated 7% of all MDR-TB patients are diagnosed.
MDR TB has several issues that can prove highly problematic
for India. As against the 6-month treatment regimen for normal
TB, MDR TB treatment can take up to two years or more to treat
with drugs that are less potent and more toxic.
Moreover, medicines for drug-resistant TB are highly
expensive. While a course of standard TB drugs costs $20, MDR TB
drugs can cost up to $5,000.
The worst form of drugresistant TB—the extreme type referred
to as XDR—is also raising its head much more frequently. WHO
estimates there may be around 25,000 XDR TB cases a year with
most proving fatal. Since XDR TB was first defined in 2006, a
total of 58 countries have reported at least one case of this
strain till 2008.
WHO also pointed to the fact that there was an urgent need
to expand and accelerate diagnosis capabilities in countries and
have technology that could diagnose MDR TB in two days rather
than traditional methods which can take up to four months.
Drug-resistant TB usually arises when people are poorly
treated or take substandard medicines. Not all countries have
the surveillance systems to pick up cases of XDR TB.
