The World Health Organization (WHO) Global Tuberculosis Report 2021 estimated that, in 2020, tuberculosis (TB) was the second most common infectious disease killer after coronavirus disease (COVID-19) and the 13th leading cause of death (1). Twenty-five per cent (25%) of the world’s population has latent TB infection, which can develop into disease. In 2020, WHO estimated that 9.9 million people fell ill with TB, but only about 5.8 million (60%) were diagnosed, reported and treated, an 18% fall from 7.1 million in 2019. WHO also estimates that, between 2019 and 2020, global TB mortality increased from 1.2 to 1.5 million, a 5.6% increase
