[The Conversation Africa] Important gains have been made in the global fight against tuberculosis (TB). Each year, fewer people are being diagnosed with the disease. The recent World Health Organisation (WHO) global TB report, which gathers data from 202 countries and territories, shows a 6.3% reduction in the number of new TB infections between 2015 and 2018. This trend of decreasing incidence is also evident in Africa, where it fell from 275 per 100 000 people in 2015 to 231 per 100 000 in 2018.
