Tuberculosis (TB) in pregnancy is not only a matter of the past; it is also a current problem. These days, TB appears through mass migration and tourism in countries where it was believed that this condition is eradicated. Adequate knowledge about the medical history of patients, risk factors, diagnosis and treatment of tuberculosis should be part of the armamentarium of each physician involved in clinical practice. TB is mainly found in urban and socially deprived areas. Due to the length of the treatment, there is an increased risk of drug resistance in partially treated patients. Strong knowledge about the history, risk factors, diagnosis and treatment of TB should be part of the armamentarium of each physician.

Bypassing a diagnosis can have a devastating effect on the mother and fetus, as well as their family and medical staff.
