The World Health Organization (WHO) has published a global TB report every year since 1997. Its purpose is to provide a comprehensive and up-to-date assessment of the TB epidemic, and of progress in the response to the epidemic, at global, regional and country levels, in the context of global commitments and strategies. The report is based primarily on data gathered by WHO in annual rounds of data collection, and databases maintained by other multilateral agencies. In 2019, data were reported by 202 countries and territories that account for more than 99% of the world’s population and estimated number of TB cases.
