world is infected with TB is based on a fundamental misunderstanding." The first BMJ article about latency was accompanied by an editorial written by Dr. Soumya Swaminathan, Deputy Director-General of the World Health Organization, who endorsed the findings and called for more funding of TB research directed at the most heavily afflicted parts of the world, rather than disproportionate attention to a relatively minor problem that affects just the wealthy countries. The World Health Organization no longer endorses the concept that all those with immunologic evidence of past TB infection are currently infected and so are at risk of developing TB some time in the future. In 2022, the WHO issued corrigenda to its 2021 Global TB Report to clarify estimates on the worldwide burden of infected people. These corrigenda deleted "About a quarter of the world's population is infected with M. tuberculosis" and replaced it with "About a quarter of the world's population has been infected with M. tuberculosis." The corrigenda also removed the prior estimate of the lifetime risk of TB of 5 to 10% among those with evidence of past TB infection, indicating that they no longer have confidence in earlier estimates that a substantial percentage of those with positive immunologic test results will develop the disease.
