According to the WHO report of 2021, approximately 10 million new cases were reported in 2020, of which 1 million occurred in the pediatric population. However, epidemiological data available on tuberculosis (TB) in pediatric age are extremely limited due to diagnostic challenges in this patient category. Furthermore, children are almost never included in national surveillance systems due to the lack of connections between individual pediatricians, pediatric hospitals, and national surveillance programs. It is therefore reasonable to assume that the disease may be significantly underestimated both in Italy and worldwide.
