Tuberculosis is not hereditary, but it can be transmitted. Generally speaking, if a pregnant woman has tuberculosis in the first three months of pregnancy, it is best to terminate the pregnancy and have another child only after the tuberculosis has been cured for more than six months. If TB is found in the middle or late stages of pregnancy, it is possible to use anti-tuberculosis treatment, which has no or little effect on the fetus. The best case is a cesarean section. If you have been treated for more than six months, there is usually no tuberculosis bacteria in breast milk and feeding is not contagious. However, TB patients themselves are less nutritious and usually have less breast milk. If it is early, after the child is born and the TB is still infectious or not fully controlled, breastfeeding is not recommended.
