US$2.15 billion plan to contain drug-resistant tuberculosis launched
22 June 2007, Geneva-- Hundreds of thousands of cases of drug-resistant tuberculosis (TB) can be prevented and as many as 134 000 lives saved through the implementation of a two-year response plan, published/launched today by the World Health Organization (WHO) and the Stop TB Partnership.
The Global MDR-TB and XDR-TB Response Plan 2007-2008 sets out measures needed now to prevent, treat and control extensively drug-resistant TB (XDR-TB)* and multidrug-resistant TB (MDR-TB)*. The plan also sets in motion actions to reach a 2015 goal of providing access to drugs and diagnostic tests to all MDR-TB and XDR-TB patients, saving the lives of up to 1.2 million patients.
"XDR-TB is a threat to the security and stability of global health. This response plan identifies costs, milestones and priorities for health services that will continue to have an impact beyond its two-year time line," said WHO Director-General Dr Margaret Chan.
The plan emphasizes the urgent need to boost basic TB control and target investment in key areas, including: strengthening programmes to treat drug- resistant TB; building capacity in diagnostic laboratories; expanding infection control and surveillance; and funding research into new and improved diagnostics, drugs and vaccines.
The plan lays out a strategy for sufficiently increasing the number of fully-equipped TB laboratories in countries with high levels of TB to achieve a ten-fold increase in detection of MDR-TB cases. If fully implemented, the plan will also increase by ten-fold the number of MDR-TB and XDR-TB patients being treated and cured under WHO guidelines.
"We have sounded the alarm on the potential for an untreatable XDR-TB epidemic. Today we issue our response on behalf of all patients and communities whose lives are most at risk. It is an ambitious plan that must be fully supported if we are to keep a stranglehold on drug-resistant TB," said Dr Mario Raviglione, Director of the WHO Stop TB Department.
The world first became aware of XDR-TB in March 2006 after researchers reported on an emerging global threat of highly resistant TB strains. Concerns were heightened six months later by a cluster of 'virtually untreatable' XDR-TB cases in an area of South Africa with high prevalence of HIV. All but one of the 53 patients died in an average of 25 days after samples were taken for drug resistance tests. Last month, the case of an air passenger from the United States infected with XDR-TB also focused attention on the need to address the TB epidemic as an immediate international priority.
"A highly important element of the plan is a steady supply of quality drugs to treat MDR-TB and XDR-TB in underserved countries," said Dr Marcos Espinal, Executive Secretary of the Stop TB Partnership. "The Partnership's Global Drug Facility is ensuring supply of these drugs to a growing number of countries, after our Green Light Committee has verified that applicant countries meet its technical standards and will use the drugs correctly."
The Global MDR-TB and XDR-TB Response Plan 2007-2008 details activities to be carried out in all six WHO regions. Its eight main objectives are those recommended by the WHO Global Task Force on XDR-TB, which met in October 2006.
The total budget for the two-year plan is US$ 2.15 billion, of which 80% is for country-specific needs. US$ 102 million is for essential support functions to fight TB drug resistance by international partners, including WHO and the Stop TB Partnership, at global, regional and national levels.
*Note to Editors:
MDR-TB is a form of TB that does not respond to the standard treatments and is defined as TB resistant to the main first-line drugs, isoniazid and rifampicin. There are an estimated 424 000 new cases of MDR-TB every year. Multidrug resistance emerges when there is mismanagement of drugs and under-investment in quality TB control. It can also be spread from one person to another. The cost of treating MDR-TB can be 1000 times more than treating standard TB.
XDR-TB occurs when there is resistance to all of the most effective anti-TB drugs, and is defined as TB with MDR-TB resistance as well as resistance to any one of the fluoroquinolone drugs and to at least one of the three injectable second-line drugs, amikacin, capromycin and kanamycin. Extensive drug resistance emerges through mismanagement of MDR-TB and can also spread from one person to another. There are an estimated 25 000 to 30 000 new cases of XDR-TB every year. So far, 37 countries have confirmed cases of XDR-TB.
