We need people – people like those in TB Alert, who are focused and ambitious and care for people at grass roots in the UK, India and Africa. Dr Lucica Ditiu, Executive Secretary of the Stop TB Partnership
It is estimated that a third of the global population is infected with latent TB - one in ten will go on to develop the disease. Annually, 8.6 million people develop TB, leading to 1.3 million deaths - deaths that are avoidable through early diagnosis and treatment.
The good news is that incidence of TB and TB-HIV coinfection is falling worldwide. But too many people continue to fall ill and die because of TB. As the world population has grown, absolute case numbers and deaths remain comparable to 1993 - the year that WHO declared TB a global emergency.
Cases of tuberculosis are concentrated in 22 ‘high-burden’ countries, countries that number among the poorest or most unequal societies. See: World Health Organisation map of TB incidence by country, 2012
TB and drug-resistance
Improper treatment, intermittent drug shortages and poor monitoring of TB patients under treatment has increased the threat of drug-resistant forms of TB. The majority of multi-drug resistant TB (MDR-TB) cases are concentrated in 27 ‘high MDR-TB burden’ countries. See: World Health Organisation map of new cases of TB with MDR-TB.
TB among people living with HIV (PLHIV)
WHO has estimated that 1.3 million lives have been saved by increased collaboration to tackle TB and HIV as a dual-epidemic. Though there is some way still to go to meet the target of halving TB-related deaths among people living with HIV (PLHIV) by 2015. See: World Health Organisation map of estimated HIV prevalence in new TB cases, 2012.
