The global tuberculosis deaths calculated by the World Health Organisation (WHO) and the Institute for Health Metrics and Evaluation (IHME) are considerable different in terms of absolute numbers for a dozen countries. This is the main conclusion of a study led by ISGlobal and published in The International Journal of Epidemiology. These discrepancies are due to different methodologies and data sources used by each institution.
The WHO estimated that the disease caused 1.8 million deaths in 2015, while the IHME, that leads the Global Burden of Disease study, estimated 1.3 million deaths for the same year. This difference of almost half a million deaths could have considerable impact on the design and evaluation of health interventions. The study detected considerable differences in particularly Nigeria, Bangladesh and Tanzania. They also identified other countries with lower disease incidence (such as Azerbaijan, Marshall Islands, Timor-Leste, Papua New Guinea or Egypt. - Carlos Sierra / PRBB
