The first estimates of the global burden of TB in children given by the WHO in 2012, suggested that there might be 530,000 children suffering from it. Subsequently there has been an uptake in the research in this field. A recent mathematical modelling study on the burden of childhood TB in 22 high-burden countries, (published in the Lancet) has revealed that there may be 650,000 annual cases of TB in children. Are these figures at odds with the estimate of 530,000 previously made by WHO?
